国内、外生态工业园实践及理论研究进展
A Review on the Practice and Research of Eco-Industrial Parks
 [PDF]

王震,
Advances in Environmental Protection (AEP) , 2011, DOI: 10.12677/aep.2011.11001
Abstract: 本文旨在从行动和理论两个层面,总结国内外目前生态工业园的实践现状和研究前沿。首先介绍了生态工业园的国内、外实践现状,并分析了其实践过程中面临的几个主要问题。其次,进一步结合国际产业生态学的研究动态,对生态工业园的一些新的理论研究方向,作了一系列的介绍(包括经济学、系统理论、社会学科等研究方向),并就生态工业园在实践中的几个热点方面做了归纳,其中包括概念在不同行业、区域中应用,以及在规划、政策等中的应用。最后,本文总结了几个当前生态工业园研究与应用三个的特点。
From the views at practice and theory levels, this paper is aimed to summarize the current situations of eco-industrial parks (EIP) both in and out China. Firstly, two problems are concluded from reviewing the current initiatives of EIP. Secondly, based on tracking an international conference of industrial ecology, some directions of research at theoretical level are introduced, which includes economic, systemic, and sociological aspects. Thirdly, this paper summarizes some new trends of applying EIP concept into practice, such as in planning and managing local industrial sectors with specific regional backgrounds. Finally, three characters of current research on EIP are provided.
水生态系统服务价值评估及工业活动影响——山东省齐河县案例
Assessment of Water Ecosystem Service Value and Industrial Impacts in Qihe, Shandong Province
 [PDF]

云昀,
Sustainable Development (SD) , 2015, DOI: 10.12677/SD.2015.53011
Abstract:
本文基于生态系统评估框架建立了针对区域复合生态系统的水生态系统服务价值评价指标体系,并对2012年山东省齐河县水生态系统服务价值进行了核算。结果显示,2012年齐河县的水生态服务价值总计为39.13亿元。其中,调节服务和文化服务的价值较高,分别为26.41亿元和9.67亿元,占总价值量的67.50%和24.71%,其次为供给服务、支持服务,分别为2.73亿元和0.32亿元。从单项水生态服务价值来看,气候调节、娱乐和生态旅游及地表水调蓄的服务价值排在前三位,分别为20.5亿元,9.67亿元和5.78亿元。工业活动会通过影响水生态系统的水量、水质和水功能而对系统服务造成影响,其中工业取水用水、废水排放和废水处理过程会直接造成水资源消耗和水污染从而影响水生态系统服务价值,而工业用地、原料能源消耗及废物排放等过程会间接损害水生态系统健康,使生态系统服务减值。
Based on the United Nations Millennium ecosystem assessment framework, this paper established a water ecosystem service evaluation system. According to the framework, we carried out the cal-culation and analysis of water ecosystem service value in Qihe, Shandong Province in 2012. The results showed that the total economic value of water ecosystem service of Qihe was 3.913 billion RMB. From the perspective of value, the highest two kinds of ecosystem services were regulating services, 2.641 billion RMB and cultural services, 0.967 billion RMB, accounting for 67.50% and 24.71% of total economic value. And the values of provision service and supporting service were 0.273 billion and 32 million. In terms of individual ecosystem service value, the top three ecosys-tem services were climate regulation, recreation & eco-tourism and surface water regulation & storage, the values of which were 2.05 billion, 0.967 billion and 0.578 billion. Industrial activities have impact on ecosystem by influencing water quantity, water quality and water functions. Among different impact factors, water consumption, wastewater discharge and treatment have a direct impact on water ecosystem service values, while industrial land use, raw materials & energy consumption and waste emission are indirect factors, which will cause impairment of ecosystem services.
Industrial ecology: a critical review
工业生态学的内涵与发展


生态学报 , 2008,
Abstract: With a development history of less than 20 years, it is time for industrial ecology to define its academic scope and theoretical basis. This paper first reviews the four main areas of industrial ecology: (1) Social metabolism, the well-developed area of industrial ecology. It provides macro-level methods and tools to observe and measure the linkages between economic development and material flows. The further research is to refine and strengthen the material flow picture and mechanism behind it; (2) Industrial symbiosis, the main characteristics of the industrial ecology fields. It is in fact the re-understanding of industrial system from waste exchanging perspectives. A unified framework with stringent rules of logic will benefit the development of industrial symbiosis theory and practice; (3) Infrastructure, cities and regional economic systems, a series of objects with spatial characteristics. Infrastructure and industries, with mutual co-evolution relationship, together constitute the material basis for the city, and then the city is the subset of the regional economic system. This group of fields needs to deal with conflicts resulting from the globalizing nature of the industry and the localization nature of social and ecological factors; (4) the diversity, complexity and sustainability of industrial development, the theoretical core of industrial ecology. All these bring great challenges to research agenda of industrial ecology, and remind us to avoid falling into the trap of simplistic reduction. Finally, four important directions are presented, following the definition of the academic scope of industrial ecology from ontology, methodology and metaphor guidelines.

单位共同犯罪中的两个关键问题

法学家 , 2006,
Abstract: 在基本形态或者本体意义上,单位犯罪就是单位的单独犯罪,既不是单位与直接责任人员的共同犯罪,也不能将其归结为直接责任人员的共同犯罪。单位共同犯罪是我国刑法的客观存在。成立单位共同犯罪,应当具备主体、主观方面等条件。在主体条件中,两个以上因为出资、隶属等原因而存在相互联系的单位共同实施犯罪的,认定是单位犯罪还是单位共同犯罪,需要明确的关键在于,实施犯罪行为的到底是一个单位还是两个以上单位。如果单位内部成员以其自然人的身份,出于自己的意志,与单位形成共同犯罪故意,应认定构成单位共同犯罪。单位与其委托代理人之间可以成立单位共同犯罪。在主观条件中,主体间的意思联络是以实行犯与其他共犯人之间具有直接意思联络为核心的。确定单位主体间具有犯罪的意思联络,关键在于单位参加犯罪是单位意志的表现。单位共同犯罪的形式,不存在单位犯罪集团的形式。
