【摘要】 作为战略环境评价的一种类型,政策环境评价是指对已有的或计划制定的政策及其替代方案可能产生的环境影响进行的系统、综合的评价过程。文章以生态系统服务功能价值为评价指标,通过对政策实施前后生态服务功能价值变化的比较分析,对吉林省生态省建设中土地利用政策的环境影响进行定量分析评价。结果表明,从生态环境和自然资源保护角度出发,该政策基本可行,但需要加强对社会用地等方面的控制。文章对生态系统服务功能价值核算理论的应用以及政策环境评价方法进行了探索。更多还原

【Abstract】 Being one type of strategic environmental assessment (SEA), policy environmental assessment (policy EA) is to analysis, predict and assess the significance of the potential environmental impacts of policy and its options or alternatives, both negative and active, in a systematic, comprehensive procedure, and then to make sure the results are considered by the policy makers and integrated into decision-making process as early as possible. Being in the higher hierarchy of decision-making, and because of the complexity and uncertainty of the proposed policies, policy EA are falling behind that of program and planning EA both in the academic researches and practices. The effective, systematic and universal methodology to policy SEA is still not formed, which is the main obstacle for its application in practice. In this study, the environmental assessment of land-use policy in Jilin Province is navigated using the possible changes of ecological service values as criteria. The ecological service values were considered to be the combined, quantitative exhibition of the conditions of ecosystem. The changes of ecological service values can reflect the impacts of land-use policy execution. It is shown that the land-use policy of Jilin Province proposed during the process of constructing ecological province is generally rational from the environmental and natural resources preservation perspectives, while the common land expansion should be controlled strictly. It is significant to apply the ecological services evaluation theory to quantitative policy SEA methods in the further studies.更多还原
