产业园区是我国经济发展的重要载体,同时也是污染物排放相对集中的区域,需要进行有效的生态环境管理。以广东省产业园区为研究对象,系统梳理了近年来产业园区生态环境管理取得的成效以及存在的不足。研究表明,广东省产业园区规划环评开展情况较好,园区污染治理能力得到有效提升,节能减排工作稳步推进,但同时也存在规划环评动态管理不及时、规划环评效力发挥不充分、园区管理机构工作机制不健全、外部生态环境监管不足等问题。针对存在的问题,从健全规划环评法规制度体系,压实园区管理机构主体责任,完善生态环境主管部门监管职责等方面提出了对策建议,以期为强化产业园区生态环境管理效能提供支撑。

落实生态文明、陆海统筹的战略离不开合理的海岸带水环境管理顶层设计。本文针对中国海岸带水环境管理构建了一套制度安排。这套制度安排以最新国家级规划和部委规章为基本政策依据,以资源环境承载力预警机制为核心内容,以满足水体的流动性及河海的连通性为基本原则,具备较强的科学性和可操作性。本文最后以环渤海地区为例给出了中央和地方各有关单位落实这套制度安排的具体工作步骤。 相似文献

雨洪管理措施的应用可有效控制雨水径流量及其污染物,系统分析雨洪管理措施对径流及其污染物的影响有助于理解雨洪管理的水环境效应。本文基于Meta方法整理国内已发表的文献案例,通过提取雨洪管理措施的类型、应用尺度、降雨特征及径流量和污染物削减率等信息,综述了雨洪管理措施应用后径流量和污染物的变化。结果表明:(1)不同雨洪管理措施所产生的水环境效应存在差异,样本中屋顶绿化的径流削减能力最强,透水铺装的径流污染物削减效果最佳;(2)雨洪管理措施对水环境的影响具有尺度效应,大尺度区域内雨洪管理措施对径流量削减作用较弱,而小尺度区域内径流污染物削减作用较弱;(3)雨洪管理措施对径流量及其污染物的削减能力随降雨量增加呈下降趋势。结合案例数据,系统分析了雨洪管理措施在径流量及其污染物控制效果上的差异及成因,可为径流调控与污染治理等实践提供理论参考。 相似文献

Risk-cost trade-offs are deemed to provide a basis for selecting between those risk reductions which are economic and those which are non-economic. Insufficient work has been done in environmental risk management decision-making practice to validate this assumption, or to develop an analytical framework within which it may be employed. Empirical evidence from the literature is offered for the existence of risk-cost trade-offs and the relationship of risk-cost trade-offs to the benefits side of the management decision-making issue is discussed. The risk-cost trade-off curve alone does not provide a complete basis for selecting between economic and non-economic risk-cost combinations. When combined with information on the willingness-to-pay for risk reductions, the risk-cost trade-off curve may be used to distinguish between risk reduction possibilities in a risk management decision-making context. Results allow for a more developed theoretical decision- making framework that, when amended for uncertainty, produces decision criteria useful for environmental risk management decision-making. 相似文献

This paper concentrates on the internal reporting methods applied to cleaner production and environmental management accounting programmes in Argentina. Questions on how environmental costs and benefits are defined, the mechanisms adopted to measure the continuing benefits arising from certain changes in management and processes and practical issues of data collection and collation are included. Furthermore, situations in which the ideally desired information is not immediately available from existing accounting or other information systems within the companies are also discussed. The success of communication initiatives, in particular, rests on both the environmental accounting messages and the ability of the users to understand the information. From this perspective, the worksheets included are considered to be an important tool to following the programmes and communicating the results. The integration of data through a set of indicators organised according to an environmentally balanced scorecard methodology may provide important information for decision-makers and add real value to sustainable development by helping people become conscious of sustainability-related matters. In addition, accountants need to know about the information improvements they can obtain using the EMA methodology. 相似文献
