陕南山地生态环境质量综合评价

A SYNTHETICAL EVALUATION OF THE ECO-ENVIRONMENT QUALITY IN THE MOUNTAINOUS REGION OF SOUTHERN SHAANXI PROVINCE

利用陆地卫星TM图像作为遥感信息源,运用GIS新技术方法,结合地学、生态学分析,以陕南山地为例,建立了山地生态环境定量评价标准、评价体系及模式。对研究区内所划分的14种生态类型单元进行了环境质量综合评价,并进一步聚类为5大景观类型区。针对各类型区环境质量分异的特点及存在的问题,提出了优化建设的对策。

Base TM image of landsat on the resource of remote-sensing information, using G1S new technology and the analysis methods of geography and ecology ,taking the mountainous region in Southern Shaanxi Province as an example,the mountainous region eco-environment quantitative evaluation standard,system and model. 14 ecology type units divided in study region are evaluated. According to these results, landscape type regions were summed 5. In connection with the characters of environment quality's difference and problems in every type region,The optimal constructive countermeasure was put forward.
