摘要
本文以青海玉树藏族自治州为研究对象,以遥感影像图为数据源,结合实地调查和社会经济等数据,采用层次分析和综合评价法对玉树州各市(县)2000年-2015年的生态承载能力进行了分析。研究结果表明:玉树州的生态承载力处于完全可载状态,各县的生态承载力排序为:治多县>曲麻莱县>称多县>杂多县>玉树市>囊谦县,特别是玉树市和囊谦县在15年间出现严重超载。在此基础上,本文进一步分析了玉树州生态承载力的空间差异以及变化规律,探讨了影响和制约该州生态环境保护的主要因素和保护对策。
This paper take yushu prefecture of sanjiangyuan region in qinghai province as the research object, making use of remote sensing image as data source, combined with field survey and social economy data, using analytic hierarchy process （AHP） and fuzzy comprehensive evaluation method to make the analysis of ecological environment carrying capacity in yushu prefecture＇s cities （counties） of 2000-2015. The research results demonstrate that the ecologieal capacity of yushu prefecture showed a trend of polarization, and can completely be carried on the whole, the order of the counties＂ capacity is： Zhiduo County 〉Qumalai County 〉Chengduo county 〉Zaduo county 〉Yushu city〉Nangqian county, Yushu city and Nangqian county have been ＇overloading Severely during 15 years. This paper analyzed the rule of the capacity of interregional differences in each county, discussing the main factors affecting and restricting Yushu prefecture＇s ecologically environmental improvement and strategies.
