【摘要】：丹江口水库是南水北调中线工程核心水源地,战略地位十分重要。本文以丹江口库区河南辖区为研究区域,以生态学、水土保持学、经济学等多种学科为基础,采用生态足迹分析法和生态系统服务价值评价法,同时又结合SPSS软件,对丹江口库区河南辖区2005-2013年间,生态环境可持续发展情况以及“丹治”工程水土保持生态系统服务功能进行定量评价,对影响该研究区生态环境可持续发展的相关因子进行精确地分析。结果表明:从2005年南水北调中线工程开工建设到2013年通水前,研究区人均生态足迹增长了1.12001hm2,人均生态承载力增长了0.063343hm2,人均生态赤字扩大了1.056658 hm2,库区生态整体上处于不可持续发展状态;城镇消费水平的过快提高是导致人均生态足迹以及人均生态赤字扩大的主要原因;2007年后,随着库区“丹治”工程等专项行动的实施,库区生态保护工作取得了一定成效,扭转了生态承载力下降的趋势。经计算,研究区“丹治”工程生态服务价值约为8.7922亿元,是其年成本的39.34倍,对研究区生态承载力提升的贡献率为39.80%,可见其生态经济效益非常显著,该工程已成为提升库区生态承载力的关键之一。在各项效益中,水圈效益尤其是水污染防治价值最为突出,是该项工程生态服务价值的最主要体现,这和该工程的实施目标是一致的。
[Abstract]:Danjiangkou reservoir is the core of North Water Transfer Project water source, the strategic position is very important. This paper take the Danjiangkou reservoir area of Henan as the study area, the soil and water conservation, ecology, economics and other disciplines, the analysis method of ecological footprint and ecological system service value evaluation method, combined with SPSS software, the Danjiangkou reservoir area the Henan area in 2005-2013 years, the quantitative evaluation of soil and water conservation ecosystem service function of ecological environment and sustainable development "tajihi" project, the accurate analysis of the related factors affecting the ecological environment of the study area of sustainable development. The results showed that: from 2005 the middle route project of South to North Water Diversion Project started construction in 2013 to pass before the water, the per capita ecological footprint research area the growth of 1.12001hm2, the per capita ecological carrying capacity increased by 0.063343hm2, the per capita ecological deficit increased by 1.056658 hm2 in students The whole state is in a state of unsustainable development; improve the level of consumption of urban too fast is the result of the per capita ecological footprint and ecological deficit per capita main reason; after 2007, with the area of "tajihi" projects such as the implementation of the special action, ecological protection work has achieved certain results, reversing the downward trend. The ecological carrying capacity calculation, research area ecological service "tajihi" project value of about 879 million 220 thousand yuan, is 39.34 times the annual cost, to enhance the ecological carrying capacity of the study area the contribution rate was 39.80%, the ecological and economic benefits is very significant, the project has become one of the key ecological carrying capacity promotion. In the benefit of the hydrosphere especially the benefit of water pollution prevention and control value of the most prominent is the main embodiment of the ecological service value of the project, and the implementation of the project objectives are consistent.
