摘要
通过分析从1996年和2005年Landsat TM影像数据提取的区域生态环境状况评价信息,在研究土地利用变化的基础上,运用RS及GIS空间分析等手段进行叠加和统计分析,借助于土地生态环境状况指数(EI)模型评价区域生态环境质量。结果表明:耕地、林地和草地三者的比例之和处于绝对优势地位,区域以农林牧业生产为主;两期区域土地生态环境状况总体一般,2005比1996年相对较好。
The regional ecological environment assessment information was extracted from the 1996 and 2005 Landsat TM image,the RS and GIS spatial analysis and other means of superposition and statistical analysis were used based on land use change.the ecological environment index（EI） model was made to evaluate the regional eco-environmental quality.The results showed that： the total proportion of farmland,woodland and grassland was dominant in study region,this region was major agriculture and forestry,land-forestland,the total of the land eco-environmental status in 2005and 1996 was general,the tendency was better compared with 1996.
