关于完善中国战略环境影响评价制度的探讨 总被引:3,自引:1,他引:2
虽然中国已经将规划环境影响评价纳入法律要求,并开始尝试更高层次的战略环境影响评价,但由于没有实施细则,战略环境影响评价制度并不完善.主要存在规则筛选程序不清晰、评价深度缺乏规范要求、审查主体的权威性不足、公众参与质量不高及评价对象的层次较低等问题.在分析上述问题的基础上,提出完善战略环境影响评价制度,提高其有效性的对策建议. 相似文献

论中国环境影响评价中公众参与的一般模式 总被引:10,自引:0,他引:10
公众参与在环境影响评价中的作用是不可替代的,并成为各国环评的基本内容.环评中公众参与的一般模式包括公众享有环境知情权和参与决策权、合适的公众参与的主体范围、明确的公众参与环评的程序和方法以及公众参与环评的保障机制.为更好地发挥环评的作用,应当从实体和程序两方面对法规加以完善.还应在信息公开、立法的完善和配套制度的建立等方面完善环评中的公众参与制度. 相似文献

环境监测在环境影响评价中的作用分析 总被引:2,自引:0,他引:2
在新时期,环境保护工作的发展面临着新的机遇和挑战。环境监测贯穿于整个环境影响评价体系之中,即环境影响评价中的评价初期、建设期、运行期以及后评价期,均需环境监测数据来支撑,因此,环境监测是环境影响评价的技术基础,同时还具有较强的监督功能。 相似文献

区域规划环境影响跟踪评价的理论研究 总被引:4,自引:0,他引:4
随着环境影响评价制度的深入实施,其实施领域已由项目环评向区域环评和规划环评转变,评价内容也由广泛实施的预测评价向后评价和跟踪评价转变。然而,对于区域规划环评的评价层次、评价程序和评价内容,目前还没有明晰的认识;同时,对于促进规划环评有效实施的跟踪评价,其相关的理论和实践研究几乎没有。文中就此问题作了深入探讨。 相似文献

基于水动力数值模型的港口规划累积影响评价 总被引:2,自引:0,他引:2
累积影响评价是战略环境评价的主要方法和重要内容之一,但目前还缺乏通用的评价程序和方法.通过识别港口规划的累积影响源和途径,建立了基于水动力数值模型的累积影响评价的量化评估和分析框架.以厦门港嵩屿港区规划为例,通过对海湾纳潮量及各敏感点流速的模拟,计算淤积量及其分布变化,进而推测海域水质和底质变化,并分析了由此引起的海洋生物群落的变化趋势.通过比较不同岸线方案的累积影响,为港区岸线优选提供了科学判据.实践表明,该方法框架综合运用定量预测和定性分析手段,其结果能为港口规划的战略环境评价提供科学依据. 相似文献

As one of the unconventional natural gas family members, coalbed methane (CBM) receives great attention throughout the world. The major associated problem of CBM production is the management of produced water. In the USA, Canada, and Australia, much research has been done on the effects and management of coalbed methane produced water (CMPW). However, in China, the environmental effects of CMPW were overlooked. The quantity and the quality of CMPW both vary enormously between coal basins or stratigraphic units in China. The unit produced water volume of CBM wells in China ranges from 10 to 271,280 L/well/day, and the concentration of total dissolved solids (TDS) ranges from 691 to 93,898 mg/L. Most pH values of CMPW are more than 7.0, showing the alkaline feature, and the Na-HCO3 and Na-HCO3-Cl are typical types of CMPW in China. Treatment and utilization of CMPW in China lag far behind the USA and Australia, and CMPW is mainly managed by surface impoundments and evaporation. Currently, the core environmental issues associated with CMPW in China are that the potential environmental problems of CMPW have not been given enough attention, and relevant regulations as well as environmental impact assessment (EIA) guidelines for CMPW are still lacking. Other potential issues in China includes (1) water quality monitoring issues for CMPW with special components in special areas, (2) groundwater level decline issues associated with the dewatering process, and (3) potential environmental issues of groundwater pollution associated with hydraulic fracturing. 相似文献

Green infrastructure (GI) and ecosystem services (ES) are promoted as concepts that have potential to improve environmental planning in urban areas based on a more holistic understanding of the complex interrelations and dynamics of social–ecological systems. However, the scientific discourses around both concepts still lack application-oriented frameworks that consider such a holistic perspective and are suitable to mainstream GI and ES in planning practice. This literature review explores how multifunctionality as one important principle of GI planning can be operationalized by approaches developed and tested in ES research. Specifically, approaches developed in ES research can help to assess the integrity of GI networks, balance ES supply and demand, and consider trade-offs. A conceptual framework for the assessment of multifunctionality from a social–ecological perspective is proposed that can inform the design of planning processes and support stronger exchange between GI and ES research. 相似文献
