摘要

以干旱内陆河流域典型区域甘肃省张掖市甘州区为研究对象

通过构建土地利用规划环境影响评价的生态安全综合指数及其评价方法

并基于GIS对研究区进行了土地利用规划前后的环境影响评价。结果表明

土地利用规划方案实施后

研究区内没有生态极不安全区分布;甘州区平均生态安全指数为2.453

处于生态较安全等级;评价结果能反映土地利用规划方案环境影响的空间特征

便于识别空间差异和主导生态环境问题

说明构建的生态安全综合指数与评价方法是可行的。

Abstract

By taking Ganzhou District in Gansu Province

a typical region in the arid inland river basin of Northwest China

as a study object and constructing comprehensive ecological security index and its assessment method

environmental impact assessments before and after land use planning were performed based on GIS techniques.Results showed that there was no extremely insecure area in the study region after performing land use planning.The ecological security index in the region was 2.453 on average

corresponding to a relatively secure statue.Result from the assessment may depict the spatial characteristics of environmental impacts by land use planning and can be used to identify the spatial variation and the problems influencing ecological environment

which implies that the comprehensive ecological security index and the evaluation method developed in the study are feasible basically.
