| 摘 要： | 根据安徽省升金湖国家自然保护区1986,1995,2000,2004,和2011年五期TM影像,运用ERDAS,ARCGIS等软件,获取了20余年升金湖保护区实验区,缓冲区,核心区三个功能区不同时期的土地利用信息,结合社会经济数据,选取影响土地利用生态风险变化指标,建立土地利用生态风险评价指标体系。在此基础上,用层次分析法和专家打分法确定指标权重,利用模糊数学综合法建立土地利用生态风险评价模型。

| Abstract: | Based on TM image of the Shengjin Lake National Natural Reserve in Anhui Province in five time slices of 1986, 1995, 2000, 2004 and 2011, this paper obtained land use information on the pilot area, buffer area and core area of the lake over 20 years, combined it with social and economic data, chose land use ecological risk change norms, and established a land use ecological risk appraisal norms system. On this basis, it determined the weight of each norm by analytic hierarchy process and expert scoring, and made an appraisal model using fuzzy math comprehensive method. |
