凤凰城旅游景区转让后的效应评价

在我国经济市场化改革的大背景下，转让景区经营权、实行企业化运作成为一些风景名胜区经营管理改革过程中的一种制度创新模式。地处西部大开发战略图中的湘西凤凰县由于在旅游开发中受到了资金缺口和管理瓶颈的双重制约，于2001年底将其辖域内的八大景区（点）的50年经营权转让给了湖南黄龙洞投资股份有限公司。景区经营权转让是一个十分复杂而敏感的话题。本文避开关于景区经营权转让的各种是非争论，基于对旅游地社区各利益主体以及旅游者的实地调查和访谈记录分析，对凤凰景区企业化运作三年来的绩效与影响作了较为客观的评估，并就如何完善景区企业化运作模式、规避经营管理风险和负面影响等提出了相关理论思考和政策建议。     

Modeling of food security and ecological footprint of coastal zone of Bangladesh

This paper presents the present status of food security and ecological footprint, an indicator of environmental sustainability of the coastal zones of Bangladesh. To estimate the present status of the food security and ecological footprint of the coastal zone of Bangladesh, primary and secondary data were collected, and the present status of food security and environmental degradation (in terms of ecological footprint) were calculated. To estimate the household food security, primary data were also collected from all the households in a representative selected village. A quantitative method for computation of food security in grain equivalent based on economic returns (price) is developed, and a method of measuring sustainable development in terms of ecological footprint developed by Wackernagel is used to estimate the environmental sustainability (Wackernagel and Rees in Our ecological footprint: reducing human impact on the earth. New Society, Gabrioala, BC, 1996; Chambers et al. in Sharing nature’s interest-ecological footprint as an indicator of sustainability. Earthscan, London, 2000). Overall status of food security at upazila levels is good for all the upazilas except Shoronkhola, Shyamnager and Morrelgonj, and the best is the Kalapara upazila. But the status of food security at household levels is poor. Environmental status in the coastal zones is poor for all the upazilas except Kalapara and Galachipa. The worst is in the Mongla upazila. Environmental status has degraded mainly due to shrimp culture. This study suggests that control measures are needed for affected upazilas and any further expansion of the shrimp aquaculture to enhance the food security must take into account the environmental aspects of the locality under consideration.     

后巴黎时代气候变化公约资金机制的构建

气候变化公约资金机制是串联全球开展应对气候变化行动的纽带,也是通过国际合作实现"2℃"乃至"1.5℃"温控目标的关键支撑。多年来,由于发达国家和发展中国家在是否依据历史责任划分履约义务上存在根本分歧,公约资金机制面临多渠道并行、运行规则多样化、资金使用分散、运行效率偏低、绩效评估欠缺等问题。本文对气候变化公约缔结20余年来各资金机制的产生和运行进行了系统梳理;对其存在的不足以及在全球气候融资体系中面临的挑战进行了剖析;并基于《巴黎协定》资金案文描述和履约要求,围绕气候资金从筹集到最终绩效产出全过程,就如何构建未来气候变化公约资金机制进行了统筹规划和设计。在机制建设层面,通过出资分摊机制以及公约下集中式管理平台的构建,确保气候资金的充足性、可预见性以及对公约的责任性;在运行操作层面,通过各渠道重点业务领域及国别资金分配体系的优化,推动气候资金的公平性和有效性;在资金使用层面,通过受援国气候资金统一管理实体和监督评估体系的建立,提高气候资金的国家主导性和环境效益。未来,公约资金机制仍将是全球开展应对气候变化国际合作的主要渠道,在《巴黎协定》达成、绿色气候基金正式运行、国际气候制度重新构建的背景下,利用资金机制推动发达国家履行公约义务,切实向发展中国家提供资金、技术和能力建设支持,对确保公约各要素的全面性和平衡性,推动全球应对气候变化行动开展,强化发展中国家集团统一立场都有着重要的现实意义。     

Adaptation of institutional arrangements to management of Northern Rangelands of Kenya

Northern Rangelands of Kenya have continued to grapple with management challenges largely due to a lack of understanding of the dynamics thereof. Eroding customary institutions and new institutional arrangements characterize the system suggesting that adaptation is taking place to cope with the change. It is imperative that these socio-ecosystems adjust to the disturbance without disintegrating into a different state that is controlled by a different set of processes to ensure sustainable rangeland management. To understand the nature of change, the study sought to evaluate institutional arrangements engaged in tackling growing socio-economic and ecological factors challenging development within the last decade. Three study sites namely Kinna, Makurian and Westgate, representing three types of institutional arrangements (elders only, group ranch committee and community conservancy board), were investigated. Key informants, focused group discussions and household survey methods were used to gather data. Data were managed and analysed using Ms Access, Ms Excel, social network analysis and SPSS. Findings indicate that more actors (internal and external) are engaging in management of social economic and ecological factors challenging development within the last decade. The co-management approach allows increased capacity to tackle these challenges and further presents more opportunities for a diversified livelihood, two key features of ecosystem resilience. Findings are useful as the Kenya government implements the National Land Policy that recognizes the need to restructure community land and its management.     

生态中心论之后现代视域的辨析

作为当代环境伦理学之生态中心论的代表,克里考特以新物理学与生态学的视角引向后现代主义的整体观。这一思路指向的是整体论系统观的范式,后者具有四项特征:1整体的性质不能被还原为部分的性质;2整体是部分形成的原因与依据;3部分是系统地互相联系的;4部分是内在地互相联系的,即关系决定存在。以该整体论系统观的范式为依据,克里考特的后现代视域既涉及本体论,也指向价值论。在本体层面,克里考特借鉴了深生态学中"充分实现的自我"的概念试图解构笛卡尔的主客二分。进而,在削弱现代哲学中三类性质(数量性、质量性与价值性)区分的同时,克里考特提出了"实质价值"的概念,并试图以实质价值消解内在价值的同时统摄固有价值与工具价值。在文本梳理的基础上,本文也考察了克里考特的后现代视域的逻辑依据与实践可能。具体地,本文指出:1克里考特以实证科学之认知来架构形上本体的思路混淆了科学命题与玄学命题的区别内涵;2建立在消解三类性质基础上的"实质价值"架空了价值本身的应然引力;3克里考特过分地强调了整体与部分的对立从而容易陷入逻辑悖论;4克里考特以关系消解实体的本质是将关系作了唯内在性的理解,而这种理解是缺乏支持力的。特别地,克里考特以整体解析部分并以关系消解个体的进路将导致伦理虚无主义。针对克里考特理论的缺陷,本文指出,以"关系"为纽结的部分与整体之间是体用统一的;而实体间的关系,既具有内在性的一面,也具有外在性的一面;并且,关系的外在性既具有本然的维度,也具有应然的维度,即,它是道德实践的必要前提。     

海洋碳汇渔业绿色发展空间外溢效应评价研究

海洋碳汇渔业绿色发展空间关联性及其外溢效应对于海水养殖业的有效协调和区域海洋环境的有效保护具有重要意义,科学估算沿海各省(自治区)海水养殖渔业碳汇量并探讨其空间相关性特征是制定差异化渔业碳汇发展政策的重要基础。根据2006—2016年中国大陆沿海9个省(自治区)的碳汇渔业资源清查数据,在检验和比较省域空间渔业碳汇总量相关性特征的基础上,运用空间计量模型分析了渔业碳汇的外溢效应及其影响因素。结果表明:①中国海水养殖渔业碳汇量整体上呈现上升趋势,但各省渔业碳汇量也存在明显差异。②研究期内的Moran's I指数整体呈现为"V"型的波动变化特征,渔业碳汇在省域空间分布上的差异性并不是随机的,而是具备显著的空间相关性。③海水养殖渔业碳汇存在明显的空间外溢效应,通过随机效应的杜宾模型分解后得出渔业产值、劳动力投入的直接效应为正,而渔业受灾面积和科研项目经费投入的直接效应为负;从间接效应来看,渔业产值在各省域间存在竞争与依存关系,海水养殖业劳动力投入和渔业技术推广的项目经费投入在各省域间存在互补关系。因此,中国沿海各省份在发挥海洋水产养殖业生态功能时,应当考虑省域区位因素,合理制定兼具差异化和协调性的海洋碳汇渔业发展政策。     

我国农村生态环境保护社区“自组织”载体刍议

当前,我国农村生态环境保护社区"自组织"的载体是居委会,已经得到法律与行政层面的认可.本文认为,社区"自组织"的载体不能仅仅局限于村委会,无论在理念层面还是在实践层面,村委会都存在着缺陷与不足,不能完全代表村民利益共同体.合作组织具有很多优势,应当成为我国农村生态环境保护社区"自组织"的重要载体之一.当前,合作组织载体作用的发挥还面临着许多难题,例如如何处理与村委会的关系、如何保证合法性等等.为此,我们认为,当前必需把合作组织自身建设与政府支持以及规范相互结合起来,合作组织自身建设的重点在于规章制度等环节,政府支持的重点在于人力资源培训以及保证合法性等环节,政府规范的重点在于立法、监督以及矫正等环节.同时,我们还要加强合作组织网络、综合性合作组织以及跨村域合作组织的建设,形成利益嵌套格局,以真正发挥合作组织在农村生态环境保护中的载体作用.     

中国参与经济全球化的区域格局响应研究

以加入WTO为标志.中国积极参与经济全球化已成为一种必然.但由于我国的国土规模、自然环境、气候条件等方面的地区差异很大,地区之间在发展水平上一直存在着差距,地区发展不平衡是个长期的国内政治经济现象.这种地区发展的差距表现为各类地区融入经济全球化的程度不同,反应不同.有些地区能够借助经济的全球化而发展自身,有些地区则无法从中受益,甚至因而处于更加落后的境地.本文从三大经济地带、各经济区和各省(市)区三个屡次分析和探讨了不同区域对经济全球化响应的差异,并对全球化条件下我国内部区域一体化格局进行了深入的研究.

The present article makes a detailed analysis on the causes of the difference. The analysis shows difference in results of the socio-economic and urban development stage, industrial features, population density, and technological progress. Finally, it proposes some suggestions to improve the efficiency of the industrial land use.     

A review of the drivers of 200 years of wetland degradation in the Mekong Delta of Vietnam

This paper examines the anthropogenic factors that have contributed to wetland loss and degradation in the Mekong Delta, Vietnam from 1816 AD to present. Our analysis is framed over five historical periods and highlights the role that seven drivers of wetland degradation have played in the Mekong Delta, including: resettlement and economic development policies; population growth and urbanization; demand for food and reclaiming wetland for agriculture; construction of canals construction of dykes flood protection systems; expansion of travel systems (waterway and roads); and exploitation of wetland natural resources. Of these, government policies for resettlement and economic development seem to have had the greatest impact on wetland loss and degradation in the Mekong Delta throughout the course of history. As a result of these factors, only 0.068 million hectares of the original 4.0 million hectares of the Mekong Delta currently remains as primary swamp forest ecosystem. History suggests that future management of the Mekong Delta should take a holistic approach that includes a better understanding of the implications of past decisions on wetland loss.     

Regulation of numbers of insects on islands of the Kuibyshev Reservoir

The main regulatory mechanism of populations is revealed for some insect groups (Carabidae, Curculionidae, Chrysomelidae, and Hemiptera) on islands of the Kuibyshev Reservoir. This mechanism is the dynamics of the ratio of species with imaginal and preimaginal winter diapause. The extent of these dynamics depends on the stability of habitats, which in turn depends on water-level conditions in the reservoir. The period of adaptation of the community of carabids of the most flooded biotope to the extreme impact of water conditions is determined.     

An overview of sustainability of common effluent treatment plant for clusters of tanneries

This paper presents an overview of sustainability of implementation of Common Effluent Treatment Plant (CETP) in Southern India. Implementation of a CETP for the treatment of combined wastewater from small-scale tannery has proved to be a techno-economic option and offered environmentally and economically sustainable method of treatment. Various aspects such as adequacy assessment and upgradation of CETP based on the treatability studies, energy audit, cost-benefit analysis, effect of implementation of CETP on surrounding groundwater and organizational management set-up were studied over a period of 4 years to analyse the sustainability of the CETP. The concept of CETP makes effective use of human, technical, and financial and natural resources and financially sustainable, i.e. being a collective responsibility, it does not fail due to financial constraints. The implementation of CETP is a true example of a step towards sustainable development and suggests that this concept can be effectively used for treatment of various industrial wastewaters emanating from small-scale clusters.     

生态文明建设的关键因素识别

生态文明建设是共创民族伟业、中国圆梦的时代重任,提高生态文明建设水平需要对生态文明建设的关键因素进行分析识别。本文从生态文明意识、生态文明制度和生态文明行为三个方面建立生态文明建设影响因素指标体系,选取全国31个省份2012至2014年的相关数据,运用BP神经网络法降低DEMATEL模型中专家打分建立关联矩阵的主观性,结合摆幅置权法(SW)得出综合重要度,遴选出生态文明建设关键因素。其中,年份最近的2014年计算得出的关键因素按照重要度排序依次为:本级环保能力建设资金使用总额、排污费解缴入库户金额、机动车污染物排放总颗粒物、网站主动公开各类政府环境信息条数和环保系统人员总数。将这些因素按照生态文明的基本内涵划分为三大类,得到3点结论:生态意识虽不起决定性作用,但能强化整个社会的生态文明建设的思想和理念,生态文明意识所占的比例先降后升,不断提高;随着生态文明建设理论和实践经验的丰富,逐渐感受到成熟的制度设计、明确的制度规范才是根本,生态文明制度类别在关键因素中所占的比例越来越高;生态文明行为作为表现形式,随着其他两方面的变化,生态文明行为不断改善,在生态文明建设的关键因素中所占比例下降。本文在生态文明意识方面提出要针对性地帮助和鼓励各级环保部门开展信息公开工作;在生态文明制度方面提出强化环保能力建设资金的监管力度,发挥排污费的真正作用,提升环保系统人员的能力素养,探索新工作思路等举措;在生态文明行为方面提出综合车、油、路等多方面措施防治机动车排放污染等建议。
