Eco-environmental stress evaluation of northeastern Shaanxi Province on a modified correspondence analysis-eco-environmental stress index (ESI)model
摘要
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 northeastern 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 northeastern Shaanxi Province.The 1 3 cities and towns in northeastern 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.关键词
