建立我国安全生产应急救援标准体系的初步构想

我国安全生产应急救援工作日益受到政府和企业的重视，但是应急救援标准非常薄弱，造成应急管理和实际救援工作困难，建立安全生产应急救援标准体系是应急救援工作和保护人民生命财产的迫切需要。在总结国内外应急救援标准工作的基础上，本文提出了我国安全生产应急救援标准体系框架以及标准制定的原则和重点。     

NUTRIENT CONCENTRATION CRITERIA AND CHARACTERIZATION OF PATTERNS IN TROPHIC STATE FOR RIVERS IN HETEROGENEOUS LANDSCAPES1

ABSTRACT: A method is demonstrated for the development of nutrient concentration criteria and large scale assessment of trophic state in environmentally heterogeneous landscapes. The method uses the River Environment Classification (REC) as a spatial framework to partition rivers according to differences in processes that control the accrual and loss of algae biomass. The method is then applied to gravel bed rivers with natural flow regimes that drain hilly watersheds in New Zealand's South Island. An existing model is used to characterize trophic state (in terms of chlorophyll a as a measure of maximum biomass) using nutrient concentration, which controls the rate of biomass accrual, and flood frequency, which controls biomass loss. Variation in flood frequency was partitioned into three classes, and flow data measured at 68 sites was used to show that the classes differ with respect to flood frequency. Variation in nutrient concentration was partitioned at smaller spatial scales by subdivision of higher level classes into seven classes. The median of flood frequency in each of the three higher level classes was used as a control variable in the model to provide spatially explicit nutrient concentration criteria by setting maximum chlorophyll a to reflect a desired trophic state. The median of mean monthly soluble reactive phosphorus and soluble inorganic nitrogen measured at 68 water quality monitoring sites were then used to characterize the trophic state of each of the seven lower level classes. The method models biomass and therefore allows variation in this response variable to provide options for trophic state and the associated nutrient concentrations to achieve these. Thus it is less deterministic than using reference site water quality. The choice from among these options is a sociopolitical decision, which reflects the management objectives rather than purely technical considerations.     

The Bhopal gas leak: Analyses of causes and consequences by three different models

The Bhopal Gas Leak, India 1984 is the largest chemical industrial accident ever. Haddon's and Berger's models for injury analysis have been tested, together with the project planning tool Logical Framework Approach (LFA).

The three models provide the same main message: That irrespectively of the direct cause to the leakage, it is only two parties that are responsible for the magnitude of the disaster: Union Carbide Corporation and the Governments of India and Madhya Pradesh. The models give somewhat different images of the process of the accident.

Models developed for analysis of injuries can be used for analysing a complicated mega accident like the Bhopal gas leak, although different models might stress different aspects.

生态文明体制全面改革的“四然”问题

生态文明体制改革的问题导向性、目标适应性、统筹兼顾性,既是现实的环境问题所迫,也是生态文明理论和建设目标的内在要求。近两年来,为了促进生态文明体制的全面改革,中央发布了《关于加快推进生态文明建设的意见》、《生态文明体制改革总体方案》等系列文件。其中,《生态文明体制改革总体方案》因对生态文明体制改革作出全面部署,理论性和实践性相结合,科学性和民主性相结合,制度规范与考核评价相结合,成为统帅生态文明体制改革的纲领性文件。系列改革文件在治理理念、治理策略、治理主体、治理结构、治理依据、治理方法、治理功能和治理体系的运转方面,逻辑自洽,提出了自己的历史使命。"十三五"时期,要使改革的措施和要求落地生根,须在营造氛围和措施的具体推进方面,开展相关的工作。     

论构建中国用能权交易体系的制度衔接之维

用能权是具有公私法双重属性的管制性财产权。用能权交易是我国推进绿色发展的一项制度创新,对实现能耗总量和强度"双控"目标具有重要意义。用能权交易制度旨在从供给侧实现节能降耗目标,与其并行的节能减排市场化机制还包括节能量交易和碳排放权交易。节能量交易与用能权交易的规制对象、规制手段、制度设计目的和约束功能相近,故两者存在制度重复建设问题。用能权交易和碳排放权交易的制度设计目的具有协同性、规制对象有交叉,但两者在用能权指标和碳排放配额初始分配、履约等方面存在制度衔接不畅问题。通过法学和制度经济学分析,对用能权交易、节能量交易和碳排放权交易的制度整合与重构提出了建议。中国应当取消目标节能量交易制度,并以核定用能权交易取代项目节能量交易。用能权交易和碳排放权交易的制度衔接层面,应当打通用能权交易体系和碳排放权交易体系,建立联合履约机制,即允许用能单位或排放单位在满足一定条件的情况下使用用能权指标、核定用能权、碳排放配额或核证减排量履约。用能权指标与碳排放配额在履约方面的衔接机制重点在于一级市场的对接。用能权的初始分配仅仅是为重点用能单位设定节能义务的过程,应当以公平为原则,并且采取免费分配的方式。相对于用能权交易制度,碳排放权交易制度则是为了控制排放单位对碳排放空间这一资源的过度利用。因此,在碳排放配额初始分配环节,政府应当通过有偿分配的方式以实现国家对碳排放空间这一稀缺资源的所有者权益。建立核定用能权和核证减排量的联合履约机制,既允许用能单位购买核证减排量抵消其超额耗能,也允许排放单位购买核定用能权以抵消其超额排放,并对抵消比例设定限制。     

生态文明制度体系研究——以江苏省为例

生态文明制度体系是由制度构成的一个相互配合、有机联系的整体。本文基于文献统计分析与实地调研咨询,从广义和狭义层面,分别对生态文明制度进行梳理。根据国家生态文明建设需求与省级层面实际情况,本文将广义的生态文明制度体系分为源头保护制度体系、损害赔偿与激励体系、追责考评制度体系和污染治理制度体系四大板块,并针对国家与省级重点生态文明制度,构建生态资源保护制度链与污染防治制度链。同时,对制度地位、制度衔接、相互关系及其优化选择进行分析,以提高环境管理效能,推进生态文明研究纵深发展。     

Valuation of ecotoxicological impacts from tributyltin based on a quantitative environmental assessment framework

In the scientific literature, few valuations of biodiversity and ecosystem services following the impacts of toxicity are available, hampered by the lack of ecotoxicological documentation. Here, tributyltin is used to conduct a contingent valuation study as well as cost–benefit analysis (CBA) of measures for improving the environmental status in Swedish coastal waters of the Baltic Sea. Benefits considering different dimensions when assessing environmental status are highlighted and a quantitative environmental assessment framework based on available technology, ecological conditions, and economic valuation methodology is developed. Two scenarios are used in the valuation study: (a) achieving good environmental status by 2020 in accordance with EU legislation (USD 119 household⁻¹ year⁻¹) and (b) achieving visible improvements by 2100 due to natural degradation (USD 108 household⁻¹ year⁻¹) during 8 years. The later scenario was used to illustrate an application of the assessment framework. The CBA results indicate that both scenarios might generate a welfare improvement.

The data not collected on community forestry

Conservation and development practitioners increasingly promote community forestry as a way to conserve ecosystem services, consolidate resource rights, and reduce poverty. However, outcomes of community forestry have been mixed; many initiatives failed to achieve intended objectives. There is a rich literature on institutional arrangements of community forestry, but there has been little effort to examine the role of socioeconomic, market, and biophysical factors in shaping both land‐cover change dynamics and individual and collective livelihood outcomes. We systematically reviewed the peer‐reviewed literature on community forestry to examine and quantify existing knowledge gaps in the community‐forestry literature relative to these factors. In examining 697 cases of community forest management (CFM), extracted from 267 peer‐reviewed publications, we found 3 key trends that limit understanding of community forestry. First, we found substantial data gaps linking population dynamics, market forces, and biophysical characteristics to both environmental and livelihood outcomes. Second, most studies focused on environmental outcomes, and the majority of studies that assessed socioeconomic outcomes relied on qualitative data, making comparisons across cases difficult. Finally, there was a heavy bias toward studies on South Asian forests, indicating that the literature on community forestry may not be representative of decentralization policies and CFM globally.     

企业环境寻求、污染密集型生产区际转移与环境监管

在当前强调产业结构调整的政策背景下,产业有序转移必须以有利于或者加强环境保护为基本目标。环境规制差异造成了不同经济地域之间污染密集型生产的比较优势调整,强化了高污染产业进行生产区位选择的动机,以规避来自政府的环境监管。环境治理成本的不同是高污染企业区际转移的重要驱动因素,企业环境寻求策略推动了污染密集型生产由环境规制强度高的地区向环境规制松弛地区的转移。企业污染密集型生产的区际转移受到环境要素产品生产比较优势的明显影响,这些环境要素产品与区际环境规制差异、企业市场内部化战略以及污染密集型产品的生命周期密切关联。借鉴一般均衡分析框架,可以明晰企业环境寻求策略下污染密集型生产转移的内在机制。一方面,环境成本差异决定了非环境友好产品生产转移的意愿,高强度的环境规制使得企业生产的边际环境治理成本和平均环境治理成本提高,污染密集型生产外迁的动力加强,生产效率高的企业对环境规制强度更加敏感。污染密集型生产承接地提高环境规制强度能形成对环境负面影响的有力对冲,遏制环境恶化趋势。另一方面,合理的区际环境政策差异能在产业有序转移中发挥重要作用。合理设定区际环境规制级差与碳信征信系统建设,加强分类监管与行业节能减排,建立拟承接生产项目的效率筛选机制,提高区域市场开放程度、降低产业优惠政策所形成隐性市场保护等环境监管手段是保证欠发达地区通过产业承接实现跨越式发展的关键所在。
