摘要: 应用RS和GIS技术,以栅格为评价单元,结合已有生态安全评价和森林生态系统健康评价研究,从生态环境状况、生态系统结构与稳定性、景观结构和外界干扰这4个方面选取指标,构建江西省生态安全评价体系。应用变异系数法、层次分析法确定权重,系统评价分析了江西省000- 2010 年时间段内生态安全变化状况。评价结果显示: 2000——2010 年,江西省生态安全指数从63. 0794升至63.2933,区城生态安全指数值较大,处于较安全等级,且整体生态状况有所好转。对江西省11个地级市2000- 2010 年的生态安全评价结果分析发现:总体上抚州市、景德镇市、吉安市、鹰潭市和宜春市生态安全水平相对较高,而萍乡市、南昌市、新余市、九江市、上饶市以及赣州市的生态安全水平则相对较低。

Abstract: Based on RS and CIS technoo ,a regiona co-scoi assn sstem comsits of regiona ecological background, coystem structure and stabli,landscape structure and exemal inerferene combined wih cological securit asesnn and forest costem heath evaluation . In this study ,evaluation unit was a grid which is 250m x 250m With the spp of coficinie of vriaio metod AHP and comprehensive evaluation mechod,a set of regiona cologica scurit asesn was cnstncted The resuts analyzed the eological securit and is trend in Jiangxi povinice Fom 20000 to 2010. During this period,, ecological securit index mose from 63. 0794 to 63.2933. They showed that the co-securt indexes value was larger and the ecologicac security situation was in a reavl sate level which indicaed that this rgion was gra clolcal stale and securwe. the cological comlition of Jiangi prvine had improved. In the analysi of cological securit evaluation resuls of 11 cities in Jiangxi Province, we find that Fuhou City ,Jingdeche Ciy ,Ji' an City,Yichum City and Yingan City have higher levels of colocal scurirytwhmie the coloicac scurit le of Pingxing City ,Nanchang, Xingu City ,Shangao City and Ganzhou City is rlatively lower.
