环境保护综合名录是实施绿色发展的抓手

绿色发展对生态文明建设具有重要支撑作用。现行的工艺导向型环境政策已不能很好地解决环境问题,难以满足绿色发展需要。环境保护综合名录属于产品导向型环境政策领域,是根据生命周期理论,对产品实施从“摇篮”到“坟墓”的全过程控制,它的鲜明特点是直接与环境保护经济政策挂钩,具有极大的生命力。因此,本文提出落实绿色发展,实践生态文明要以环境保护综合名录为抓手,并针对如何强化环境保护综合名录政策,提出以下建议:进一步提升名录制定工作的科学性与规范性;完善名录运行机制;制定与发布环保综合名录手册,在以往名录工作机制重“双高”定性的基础上,深入分析“双高”产品的污染节点、治理难点和监管重点,作为地方环保部门环保执法和政策制定的依据与参考;环境保护综合名录需要进一步实施推广与执法机制,使环境保护综合名录政策直接转变成生产力,这是环境保护综合名录政策直接落实到转变发展方式上的落脚点;强化环境保护协同控制政策,做好编制综合名录工作。

国家生态工业示范园对企业绿色创新的影响研究

国家生态工业示范园是中国工业绿色转型的主要载体。本文基于创建国家生态工业示范园为切入点,采用多期双重差分法（difference-in-differences, DID）和2002-2017年上市公司的面板数据,实证考察了国家生态工业示范园对企业绿色创新的影响。研究发现：①创建国家生态工业示范园显著促进了企业绿色创新,平均提升了上市公司绿色发明专利0.883项,绿色实用专利0.465项;②事件分析表明,国家生态工业示范园与企业绿色创新之间存在着“先增后降”的倒“U”形关系;③国家生态工业示范园显著增加了企业环保投资,抑制了企业排污费,但与政府环保补助之间没有必然联系;④国家生态工业示范园更有助于非国有企业、经营状况比较好的企业以及东部经济发达地区的企业绿色创新,并且其绿色创新效应不集中于特定行业（如重污染行业）。本文从微观企业层面为理解创建国家生态工业示范园的经济社会效益提供了启发。     

生态产品价值实现的“一村万树”绿色期权模式

随着经济的不断发展，越来越多的国家和地区开始重视绿色高质量发展，对生态产品的研究也在不断加强。各种政策工具相继出现，致力于将自然给予的生态产品资本化，并赋能经济发展。其中，衢州市柯城区的“一村万树”项目就是一种具有创新性的生态产品价值实现模式。本文对衢州市柯城区“一村万树”项目及其绿色期权模式进行研究，结合部门统计数据和空间信息数据，对“一村万树”项目实施区2018年的生态效益进行核算，并选取柯城区2010—2018年相关社会经济统计数据进行相关性分析，探析项目的社会经济效益，最后在量化分析的基础上结合公共池塘资源治理的八条设计原则，定性分析了“一村万树”绿色期权的合理性。结果显示：“一村万树”实施区2018年的生态效益为124.63亿元，约为研究区国内生产总值估算值的1.68倍，说明该项目具有巨大的生态效益；同时，相关分析结果表明该项目实施对当地第三产业的发展有较大的促进作用。柯城区“一村万树”项目以及绿色期权模式给当地带来了巨大的生态和社会经济效益，为我国的乡村绿化建设和生态产品价值实现提供了一种新范式。     

中国绿色转型测度与绿色消费贡献研究

本文通过构建综合性绿色转型指标和指数体系,测度了中国2004—2018年绿色转型进展。从计算结果看,2004—2008年,绿色转型指数逐年大幅提高;2009—2015年,绿色转型指数上升趋势减缓;2016年以来,绿色转型指数出现略微下降,其中,生产领域绿色转型指数的增大对整体绿色转型程度的提高起着关键支撑作用,但生产领域绿色转型增速开始放缓,消费领域绿色转型指数下滑趋势明显。为进一步推动中国绿色转型,针对消费领域亟待构建形成绿色消费政策体系,强化绿色消费激励约束机制,使得绿色消费成为促进生态环境质量改善的新抓手和推动经济高质量发展的新动能。     

工业园区绿色发展重点领域及其开发性金融应用研究

工业园区的绿色发展是我国经济绿色转型和可持续发展的基石,对实现我国生态文明建设具有重要的意义。而工业园区绿色发展中的基础设施建设等任务的资金需求周期长、盈利性较弱,极其需要开发性金融的大力支持。本文识别了开发性金融引导工业园区绿色发展的重点领域,主要包括构建生态产业链、完善环境基础设施建设、推进清洁生产、促进园区环境能力建设等,并进一步分析了各领域的建设目的、重点项目及实施主体。同时,从加强多方合作、优化投融资方式等角度,提出提升开发性金融服务能力、有效支持工业园区绿色发展的建议。     

特大城市集群绿色发展与生态足迹关联特征

本文以成渝城市群、长江中游城市群和长三角城市群为研究对象,解析不同空间尺度下绿色发展与生态足迹时空变化特征,并结合耦合协调度模型、环境库兹涅茨曲线（EKC）理论探究绿色发展与生态足迹的关联特征。研究表明,长江经济带城市群2000—2015年绿色发展水平逐年提升,约16.44%的城市达到较高水平,空间上呈现“东部高、西部低”的特征。人均三维生态足迹增长逐渐趋缓,成渝城市群达到峰值（5.21hm²）后逐年稳定下降。长江经济带绿色发展与生态足迹处于良好协调状态,绿色经济的快速发展带动了耦合协调度的提高。绿色发展与生态足迹存在倒“ U”形EKC曲线关系,由于自然资源基础和产业结构差异,成渝城市群（拐点出现在2008年）绿色发展与生态足迹协调关系好转早于中下游城市群（拐点分别在2019年、2012年）。四川、安徽应作为降低资源消耗的重点对象,未来应进一步加强区域中心城市的辐射带动作用,拉动周围城市提高绿色发展水平。研究成果能为区域绿色发展与生态环境协同管理提供思路与理论支持。     

Exergy and extended exergy accounting of very large complex systems with an application to the province of Siena, Italy

This paper describes the application of exergy and extended exergy analyses to large complex systems. The system to be analysed is assumed to be at steady state, and the input and output fluxes of matter and energy are expressed in units of exergy. Human societies of any reasonable extent are indeed Very Large Complex Systems and can be represented as interconnected networks of N elementary "components", their Subsystems; the detail of the disaggregation depends on the type and quality of the available data. The structural connectivity of the "model" of the System must correctly describe the interactions of each mass or energy flow with each sector of the society: since it is seldom the case that all of these fluxes are available in detail, some preliminary mass- and energy balances must be completed and constitute in fact a part of the initial assumptions. Exergy accounting converts the total amount of resources inflow into their equivalent exergetic form with the help of a table of "raw exergy data" available in the literature. The quantification of each flow on a homogeneous exergetic basis paves the way to the evaluation of the efficiency of each energy and mass transfer between the N sectors and makes it possible to quantify the irreversible losses and identify their sources. The advantage of the EEA, compared to a classical exergy accounting, is the inclusion in the system balance of the exergetic equivalents of three additional "Production Factors": human Labour, Capital and Environmental Remediation costs. EEA has an additional advantage: it allows for the calculation of the efficiency of the domestic sector (impossible to evaluate with any other energy- or exergy-based method) by considering the working hours as its product. As implied in the title, an application of the method was made to a model of the province of Siena (on a year 2000 database): the results show that the sectors of this Province have values of efficiency close to the Italian average, with the exception of the commercial and energy conversion sectors that are more efficient, in agreement with the rather peculiar socio-economic situation of the Province. The largest inefficiency is found to be in the transportation sector, which has an efficiency lower then 30% in EEA and lower than 10% in classical exergy accounting.     

Assessing the Effectiveness of a Constructed Arctic Stream Using Multiple Biological Attributes

Objective assessment of habitat compensation is a central yet challenging issue for restoration ecologists. In 1997, a 3.4-km stream channel, designed to divert water around an open pit diamond mine, was excavated in the Barrenlands region of the Canadian Arctic to create productive stream habitat. We evaluated the initial success of this compensation program by comparing multiple biological attributes of the constructed stream during its first three years to those of natural reference streams in the area. The riparian zone of the constructed stream was largely devoid of vegetation throughout the period, in contrast to the densely vegetated zones of reference streams. The constructed stream also contained lower amounts of woody debris, coarse particulate organic matter (CPOM), and epilithon; had lower coverage by macrophytes and bryophytes; and processed leaf litter at a lower rate than reference streams. Species richness and densities of macroinvertebrates were consistently lower in the constructed stream compared to natural streams. This contributed to differences in macroinvertebrate assemblage structure throughout the period, although assemblages showed some convergence by year 3. The effectiveness of the constructed stream to emulate natural streams varied somewhat depending on the biological attribute being evaluated. Assessments based on individual attributes showed that minimal to moderate levels of similarity between the constructed stream and natural streams were achieved. A collective assessment of all biological and ecosystem attributes suggested that the constructed stream was not a good surrogate for natural streams during these first years. Additional time would be required before many characteristics of the constructed stream would resemble those of reference streams. Because initial efforts to improve fish habitat in the constructed stream focused on physical structures (e.g., weirs, vanes, rock, groins), ecological factors limiting fish growth were not considered and likely constrained success. We suggest that a greater focus on organic characteristics and vegetation within the stream and its riparian zone could have accelerated compensation. The addition of woody debris and CPOM, combined with planting of shrubs and herbs along the stream, should provide a source of allochthonous matter for the biotic community while large cobble and boulders should improve the physical stability of stream system, protecting its organic components.     

Conversion of temperate forests into heaths: Role of ecosystem disturbance and ericaceous plants

Fire and logging in nutrient-poor temperate forests with certain ericaceous understory plants may convert the forests into heaths. The process of disturbance-induced heath formation is documented by using examples ofCalluna in western Europe,Kalmia in Newfoundland, andGaultheria (salal) in coastal British Columbia. In a cool, temperate climate, rapid vegetative growth ofCalluna, Kalmia, and salal following disturbance results in increasing organic accumulation (paludification), nutrient sequestration, soil acidification, and allelochemicals. These are thought to be the main reasons to conifer regeneration failure in disturbed habitats. If continuation in forest is a land-use objective, then temperate forests with an ericaceous understory should not be logged unless effective silvicultural methods are devised to control the ericaceous plants and restore forest regeneration. Preharvest vegetation control may be considered as an option. Failure to control the understory plants may lead to a long-term vegetation shift, from forest to heathland, particularly in nutrient-poor sites. Successful methods of controllingKalmia andGaultheria, however, have yet to be developed. While theKalmia- andGaultheria- dominated heathlands are undesirable in Canada and the Pacific Northwest, a wide range ofCalluna heathlands of western Europe are being conserved as natural and seminatural vegetation.     

Urban ecological systems: scientific foundations and a decade of progress

Urban ecological studies, including focus on cities, suburbs, and exurbs, while having deep roots in the early to mid 20th century, have burgeoned in the last several decades. We use the state factor approach to highlight the role of important aspects of climate, substrate, organisms, relief, and time in differentiating urban from non-urban areas, and for determining heterogeneity within spatially extensive metropolitan areas. In addition to reviewing key findings relevant to each state factor, we note the emergence of tentative "urban syndromes" concerning soils, streams, wildlife and plants, and homogenization of certain ecosystem functions, such as soil organic carbon dynamics. We note the utility of the ecosystem approach, the human ecosystem framework, and watersheds as integrative tools to tie information about multiple state factors together. The organismal component of urban complexes includes the social organization of the human population, and we review key modes by which human populations within urban areas are differentiated, and how such differentiation affects environmentally relevant actions. Emerging syntheses in land change science and ecological urban design are also summarized. The multifaceted frameworks and the growing urban knowledge base do however identify some pressing research needs.     

Neighbourhood characteristics and urban gardens in the Toledo metropolitan area: staffing and voluntarism,food production,infrastructure, and sustainability practices

Urban gardens are important sources of sustenance for communities with limited access to food. Hence, this study focuses on food production in gardens in the Toledo metropolitan area in Northwest Ohio. We administered surveys to 150 garden managers from November 2014 to February 2015 in our attempt to better understand how neighbourhood racial composition and poverty levels are related to staffing and voluntarism, food production and distribution, the development of infrastructure, and the adoption of sustainability practices in urban gardens. The results from 30 gardens are presented in this paper. We used Geographic Information Systems to map the gardens and overlay the map with 2010 census data so that we could conduct demographic analyses of the neighbourhoods in which the gardens were located. Though the gardens were small – two acres or less – up to 46 varieties of food were grown in a single garden. Gardens also operated on small budgets. Food from the gardens was gifted or shared with friends, family, and neighbourhood residents. Gardens in predominantly minority neighbourhoods tended to have fewer institutional partners, less garden infrastructure, and had adopted fewer sustainable practices than gardens in predominantly White neighbourhoods. Nonetheless, residents of predominantly minority and high-poverty neighbourhoods participated in garden activities and influenced garden operations. Volunteering and staffing were racialised and gendered.     

Using Paleo Reconstructions to Improve Streamflow Forecast Lead Time in the Western United States

In water stressed regions, water managers are exploring new horizons that would help in long‐range streamflow forecasts. Oceanic‐atmospheric oscillations have been shown to influence streamflow variability. In this study, long‐lead time streamflow forecasts are made using a multiclass kernel‐based data‐driven support vector machine (SVM) model. The extended streamflow records based on tree ring reconstructions were used to provide a longer time series data. Reconstructed data were used from 1658 to 1952 and the instrumental record was used from 1953 to 2007. Reconstructions for oceanic‐atmospheric oscillations included the El Niño‐Southern Oscillation, Pacific Decadal Oscillation, Atlantic Multidecadal Oscillation, and North Atlantic Oscillation. Streamflow forecasts using all four oscillations were made with one‐year to five‐year lead times for 21 gages in the western United States. This is the first study that uses both instrumental and reconstructed data of oscillations in SVM model to improve streamflow forecast lead time. SVM model was able to provide “satisfactory” to “very good” forecasts with one‐ to five‐year lead time for the selected gages. The use of all the oscillation indices helped in achieving better predictability compared to using individual oscillations. The SVM modeling results are better when compared with multiple linear regression model forecasts. The findings are statistical in nature and are expected to be useful for long‐term water resources planning and management.     

Predicting deer-vehicle collisions in an urban area

Collisions with deer and other large animals are increasing, and the resulting economic costs and risks to public safety have made mitigation measures a priority for both city and wildlife managers. We created landscape models to describe and predict deer-vehicle collision (DVCs) within the City of Edmonton, Alberta. Models based on roadside characteristics revealed that DVCs occurred frequently where roadside vegetation was both denser and more diverse, and that DVCs were more likely to occur when the groomed width of roadside right-of-ways was smaller. No DVCs occurred where the width of the vegetation-free or manicured roadside buffer was greater than 40 m. Landscape-based models showed that DVCs were more likely in more heterogeneous landscapes where road densities were lower and speed limits were higher, and where non-forested vegetation such as farmland was in closer proximity to larger tracts of forest. These models can help wildlife and transportation managers to identify locations of high collision frequency for mitigation. Modifying certain landscape and roadside habitats can be an effective way to reduce deer-vehicle collisions.     

AN APPLICATION RUNOFF MODEL STRATEGY FOR UNGAGED WATERSHEDS1

ABSTRACT: Mathematical models for predicting watershed surface flow responses are available, most of which are elaborate nonlinear numerical surface and channel flow models linked with infiltration models. Such models may be used to make predictions for ungaged areas, assuming an acceptable fitting of the model to the topography and roughness of the real system. For some application purposes, these models are impractical because of their complexity and expensive computer solutions. A procedure is developed that uses a complex model of an ungaged area to derive a simpler parametric nonlinear system model for repetitious simulation with input sequences. The predicted flow outputs are obtained with the simpler model at significant savings of money and time. The procedures for constructing a complex kinematic model of a 40 acre (161,880 m²) reference watershed and deriving the simpler system model are outlined. The results of predictions from both models are compared with a selected set of measured events, all having essentially the same initial conditions. Peak discharges ranged from 3 to 118 ft³/sec (0.085 to 3.34 m³/sec), which includes the largest event of record. The inherent limitations of lumped systems models are demonstrated, including the bias caused by their inability to model infiltration losses after rainfall ceases. Computer costs and times for the models were compared. The derived simple model has a cost advantage when repeated use of a model is required. Such an applications hydrologic model has an engineering tradeoff of reduced accuracy, and lumping bias, but is more economical for certain design purposes.     

MANGANESE CYCLE IN IMPOUNDMENT WATER

Manganese entering impounded water will undergo a cyclic transformation. Oxidation precipitates manganese from top waters. At the bottom of the lake, biological activity will render manganese soluble by both intracellular as well as extracellular activity. The study was made to demonstrate that biological reduction and transformation, organometallic complexation, together with the presence of carbon dioxide and the lowering of pH all have some effect on the solubility of manganese. Dissolved manganese may be brought back to top waters during the lake overturn and therefore deteriorates the water quality.     

Surface applied water treatment residuals affect bioavailable phosphorus losses in Florida sands

Water treatment residuals (WTR) can reduce runoff P loss and surface co-application of P-sources and WTR is a practical way of land applying the residuals. In a rainfall simulation study, we evaluated the effects of surface co-applied P-sources and an Al-WTR on runoff and leacheate bioavailable P (BAP) losses from a Florida sand. Four P-sources, namely poultry manure, Boca Raton biosolids (high water-soluble P), Pompano biosolids (moderate water-soluble P), and triple super phosphate (TSP) were surface applied at 56 and 224kgPha(-1) (by weight) to represent low and high soil P loads typical of P- and N-based amendments rates. The treatments further received surface applied WTR at 0 or 10gWTRkg(-1) soil. BAP loss masses were greater in leachate (16.4-536mg) than in runoff (0.91-46mg), but were reduced in runoff and leachate by surface applied WTR. Masses of total BAP lost in the presence of surface applied WTR were less than approximately 75% of BAP losses in the absence of WTR. Total BAP losses from each of the organic sources applied at N-based rates were not greater than P loss from TSP applied at a P-based rate. The BAP loss at the N-based rate of moderate water-soluble P-source (Pompano biosolids) was not greater than BAP losses at the P-based rates of other organic sources tested. The hazards of excess P from applying organic P-sources at N-based rates are not greater than observed at P-based rates of mineral fertilizer. Results suggest that management of the environmental P hazards associated with N-based rates of organic materials in Florida sands is possible by either applying P-sources with WTR or using a moderate water-soluble P-source.
