摘要

针对传统生态环境压力指数(ESI)模型评价结果缺少普适性的缺陷, 本研究提出改进的对应分析- ESI模型, 并以2010年陕西省北部地区为例进行社会经济发展对生态环境压力的特征及成因分析. 在生态环境压力法评价各市县生态压力等级的基础上, 利用对应分析法根据影响指标的不同将各市县分类, 并提出相应的应对策略. 结果表明: 1) 陕西省北部地区主要的生态环境的压力来源于环境污染. 2) 陕西省北部地区13个市县可分为3个区: Ⅰ区应适度转换耕地用途; Ⅱ区应着重治理工业三废问题; Ⅲ区应减少农用化肥施用量以及降低生活污水的排放量.

Abstract

Since results from the Eco-environmental stress index (ESI) method could not be generalized , a correspondence analysis-ESI method ( CA-ESI) was developed . The new method was used to , analyze the origin and characteristics of eco-environmental stress due to economic development in north eastern Shaanxi Province in 2010 . After evaluation of eco-environmental stress in each city and each town with traditional ESI , correspondence analysis was applied to categorize the cities and towns according to influence index , strategies to mitigate eco-environmental stress were proposed accordingly for each category . Environmental pollution was found to be the main eco-environmental stress in north eastern Shaanxi Province . The 13 cities and towns in north eastern Shaanxi Province could be divided into three regions . Cultivated land of region I should be cautiously changed to other usages . In region II , special attention should be directed to remediation of the three industrial wastes . Agricultural fertilizer as well as sewerage discharge should be reduced in region III
