摘要

以江淮分水岭部分为研究对象

选取植被指数、干度指数、湿度分量、地表温度分别表示绿度、干度、湿度和热度等指标

结合主成分分析法构建了生态系统质量综合评价指数(CEQEI)

对研究区的生态环境状况进行了综合评价。结果表明

研究区CEQEI的均值从2000年的0.357增长至2005年的0.529

继续增长至2010年的0.615

说明该区生态环境整体状况不断改善。研究表明CEQEI能够较为系统地对研究区的环境状况进行评价。

Abstract

Jianghuai watershed area was selected as the research object. The vegetation index

dryness index

humidity component and surface temperature were selected to express green degrees

dryness

humidity and heat indexes. Comprehensive ecological quality evaluation index(CEQEI) was built in combination with principal component analysis to evaluate ecological environment condition comprehensively in the study area. The results showed that the average of CEQEI growth from 0.357 in 2000 to 0.529 in 2005

and it continued to grow to 0.615 in 2010. It indicated that the whole situation of ecological environment improved continually

and CEQEI could be used to evaluate the environmental conditions systematically in the study area.
