摘要

生态省(市、县)和国家级生态示范区建设指标的引入

可以进一步完善区域土地生态安全评价指标体系。依据区域土地生态安全评价一般性指标体系和现有的土地生态安全评价实例

结合江苏省的实际情况

建立了由18项指标组成的土地生态安全评价指标体系。运用层次分析法确定各指标权重

通过加权求和计算得到江苏省2000

2005和2008年的土地生态综合安全值分别为0.812

0.840和0.845。研究结果表明

江苏省土地生态安全水平达到良好级。通过对江苏省土地生态安全进行评价研究

可为江苏省土地资源的可持续利用提供理论基础和实践经验。

Abstract

The specific establishment of evaluation indices for ecological demonstration area at provincial orcounty levels can improve the index systems for assessing regional ecological security of land resources.Anindex system consisting of 18indices was established for Jiangsu Province based on the commonly used indices and existing examples of evaluation.The current status of the province was carefully considered in establishing the index system.Analytic hierarchy process method was applied to determine the weight of each index.Weighted sums as comprehensive scores of ecological security were 0.812

0.840and 0.845for theyears 2000

2005and 2008

respectively

indicating good land ecological security status of Jiangsu Provincein these years.The evaluation of land ecological security can provide theoretical basis and practical experiencefor the sustainable use of land resources in Jiangsu Province.
