ECO-ENVIRONMENTAL SYNTHETIC EVALUATION BASED ON GIS TECHNOLOGY IN HUNAN PROVINCE
研究结合GIS与层次分析法，评价湖南省生态环境，发现其空间格局从东向西递减，自然因素起决定作用，但灾害、污染和社会经济也有影响。
Eco-environment evaluation index system includes many indexes,and the result of evaluation should reflect the spatial pattern of regional eco-environment.In order to analyze and evalute eco-environment in Hunan province,this research use the combination of geographical information system(GIS) with AHP.The result found that eco-environmental situation of Hunan province decreases from east to west.With exception in a few areas,the spatial pattern of society economic and eco-environment is consistent with that of natural environment.It indicates that natural factors determine the spatial pattern of eco-environment of Hunan province.However,some other factors also affect the eco-environment and influence its spatial pattern in some cases,such disasters,pollution and society and economic.
