中文摘要	吉林西部是一个典型的自然、经济和社会的复合系统,生态环境脆弱,土地沙化、碱化严重.在分析该区环境的基础上,提出了生态系统退化度的概念.以长岭县为例建立了生态系统退化度评价指标体系,包括土地背景质量、生态环境现状、经济发展水平、生态破坏速度诸要素15项指标.运用RS、GIS和数据库管理技术建立了生态系统退化度研究数据库.采用层次分析法,开展了以乡为单元的生态系统退化度评价,用MapInfo软件绘制了生态系统退化度数字化图,为研究区的生态建设提供了科学依据.
英文摘要	The western of Jilin Province is a typical compound system of nature, economy and socie-ty, with vulnerable eco-envirohment. The desertification and basification of the soil is serious there. Based on the environment analysis, it was put forward that the concept of the eco-environment degraded degree (EDD). The estimation flow was built taking Changling County as an example ( and the index system as well, which was composed of thirteen indexes such as soil quality, eco-environment states, e-conomy developing level, ecology destroying speed and so on. Database on EDD study was built using RS, GIS and database management technology. Adopting analytic hierarchy process (AHP) , EDD esti-mation was developed taking village as a unit, and numerical figures were protracted by Maplnfo. The study afforded scientific foundation on ecology construction of the area.
