摘    要:采用GIS技术与层次分析法相结合,对湖南省生态环境质量状况进行了综合评价。通过建立综合评价的指标体系和基本评价单元,应用层次分析法确定各评价指标的权重,再运用GIS技术,计算评价单元的质量指数和分指数,自动生成湖南省生态环境综合评价等级图,并从自然环境、灾害状况、环境污染和社会经济状况方面进行了空间分界规律分析。结果表明,社会经济与自然环境状况的空间格局大体吻合,湖南省生态环境质量基本上由东向西逐渐降低,但局部地区有差异。说明自然条件对湖南省生态环境质量的空间分异起主要作用,但灾害状况、社会经济和环境污染等因素也在一定程度上影响了生态环境质量的空间格局。

关 键 词:GIS  层次分析法  生态环境综合评价  湖南省

Abstract:Eco-environment evaluation index system includes many indexes,and the result of evaluation should re- flect the spatial pattern of regional eco-environment. In order to analyze and evalute eco-environment in Hunan province,this research used the combination of geographical information system(GIS) with AHP. The mathemat- ical methodology for study on eco-environment was explored and developed. This research focused on the analysis of eco-environment in Hunan province. Firstly,this paper set up the eco-evironment indexes system based on the eco-evironmental characteristic of Hunan province. Secondly,calaculating the weight of each selected indexes and the value of each evluation cell by AHP. Finally,got the synthetic eco-environment evaluation result map of Hu- nan province by GIS. It found that eco-environmental quality 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.
Keywords:GIS  AHP  eco-environmental synthetic evaluation  Hunan province
