基于适应性管理的水污染控制体系构建——以太湖流域为例

从规划内容与目标、规划方法及方案实施和评估3方面对太湖近20年水污染物控制历程进行综合分析,认为太湖水污染物控制正处面源污染、生活污染及新型污染问题凸显且更难处理,更为广泛的利益相关者和科研队伍积极参与的转型期.这种变化将导致污染治理面临更难应付的动态性和复杂性,使得当前以环境容量为总量为指导通过自上而下分配排污量和削减量的控制方案面临极大挑战.结合太湖水污染现状,通过与现行治理方法在管理假设、适合对象、协调管理手段、管理目标、规划方法、公众参与程度以及规划的优劣势等方面的比较发现,适应性管理可以积极有效应对由于环境趋势和管理协调对象变化所带来的系统不确定性和复杂性,将是一个积极有效的补充方法.同时,本文基于适应性管理提出了太湖水环境污染物排放控制体系的构建框架,突出适应性管理平台、科学研究及公众与基层单位参与在污染物控制中的重要作用.     

试论宜居性城市绿地的规划与建设

在生态城市、可持续发展等社会思潮的推动下,宜居性城市已逐渐成为新的城市发展观。我国的城市绿地建设也由过去的点缀性工作上升为城市基础设施建设的重点内容。但从城市的宜居性角度分析,我国城市绿地的规划与建设主要存在定位比较模糊,重综合公园和专类公园绿地、轻社区绿地,重绿地美化亮化效果、轻绿地生态效益,重整体性评价指标、轻宜居性指标等问题。立足于城市绿地规划的宜居性导向,提出了合理定位、绿地工程与主体工程“四同时”, 按自然规律进行城市绿地的建设与管理,突出社区性绿地,推行“绿径＋缀块”的绿地网络布局,强调绿地的“可达性＋开放性＋复合性”,以及适度兼顾绿地规模等宜居性城市绿地规划与建设的策略。     

福州市城区内河引闽冲污后水质变化趋势及防治对策

简述了福州市城区内河河网结构特点和河网水文特征,对1994年-2003年福州城区内河的水质变化趋势进行了分析和评价。结果表明,自1998年福州市全面开始内河引水冲污工程后,内河水质得到了改善,有机污染得到缓解,基本消除了水体的黑臭现象。指出了在内河整治中存在的一些问题。提出,应优化引水方案,最大限度发挥效益;明确河段的使用功能,发挥其潜能;开展生物防治,建立良性循环的水生生态系统,对内河实施综合管理。

Transnational environmental collective action facing implementation constraints – the case of nutrient leakage in the Baltic Sea Action Plan

While scholars have showed a long-standing interest for how to design effective environmental treaties and other international agreements, less interest has been paid to implementation phases of these agreements. This article takes the Eutrophication Segment in the Baltic Sea Action Plan as an example of a regional effort to reduce nutrient leakages, where national reporting of adopted strategies has been a key mechanism to improve implementation effectiveness. It is shown that although transnational collective action theory is a powerful tool to analyse underlying drivers and priorities in state implementation policies, a deeper analysis of domestic and external constraints can shed additional light on observed implementation gaps. Varying views among countries on, for example, the role of stakeholder participation, legitimacy and top-down governing versus multi-stakeholder governance approaches may comprise domestic constraints that make effective and efficient implementation problematic. In terms of external constraints, states’ balancing of action plan objectives versus other international commitments, such as other environmental treaties and EU Directives, is shown to potentially reduce implementation efficiency as well.

A methodology for assessing urban sustainability: Aalborg commitments baseline review for Riga, Latvia

Both the Aalborg Commitments and the guidance on integrated urban environmental management and sustainable urban transport plans proposed by the EU Thematic Strategy on the Urban Environment foresee a baseline review as the first step in developing integrated urban management plans and systems. A baseline review of urban sustainability undertaken in Riga reveals significant discrepencies between the sustainability criteria of the Aalborg Commitments and the: responsibilities and competencies of the municipal government and administration as defined by statutes; policy goals and measures defined in municipal planning documents; policy goals and measures defined in the Riga Development Plan. To better orient the mandate of the municipality towards sustainable development, municipal statutes should be supplemented to more fully reflect the issues defined by the Aalborg Commitments and should include sustainability as a goal. In order to strengthen the implementation of sustainable development specific policy goals, measures and targets should be formulated for all the Aalborg Commitments issues when revising existing municipal planning documents or developing a municipal sustainable development management plan. An analysis of the European Common Indicators and the State of the Environment in Riga 2001 indicators indicates that they can only partially fulfill a monitoring function for the implementation of the Aalborg Commitments. This highlights a need to better coordinate sustainable development initiatives at the European level. The methodology used for the baseline review in Riga is useful for assessing the status of urban sustainability when preparing integrated urban management plans or systems, but requires testing elsewhere.
