摘    要:该文以鲁中南山区泰安市为例,构建了土地生态环境状况评价指标体系。利用RS技术从TM影像上提取土地生态环境状况评价信息,与GIS技术结合,通过土地生态环境状况指数(EI)模型进行评价,对比两期评价结果研究其土地生态环境状况的变化情况。研究结果表明:2005年泰安市土地生态环境状况总体良好,优等占总面积的14.34%,良占39.19%,一般占12.40%,较差占15.61%,差占18.46%,与1987年相比有变好的趋势。在各类别分析的基础上,提出了泰安市土地生态环境保护措施。该研究探索了RS和GIS技术相结合的土地生态环境状况评价方法,分析了区域土地生态环境状况及其变化趋势,对区域土地生态环境的保护和改善具有积极意义。

关 键 词:遥感  GIS  土地生态环境状况  动态变化  泰安市

Abstract:This study chose the middle and southern mountainous region of Shandong province and took Tai'an City as a case study.Index system of land eco-environmental status evaluation was constructed.The land eco-environmental information was extracted from the TM images by remote sensing technique,evaluation method was adopted combining RS and GIS technique,evaluation was conducted by land eco-environmental status index(EI)model,and dynamic change was completed by comparison results of the two period evaluations.The results show that the land eco-environmental status in Tai'an City was generally good in 2005.The area of the excellent grade is 14.34%of the total area,that of the good grade was 39.19%,the common grade was 12.40%,the worse grade was 15.61%and the worst grade was 18.46%of the total area.Compared with that of 1987,the land eco-environmental status had a meliorate trend.Based on the analysis of the various land categories in Tai'an City,the land eco-environment protection measures were advanced.Land eco-environmental status evaluation methods were explored which combined RS and GIS technique,and the regional land eco-environment status and the variation trend were analyzed;therefore,this study has noticeable significance to the regional land eco-environment protection and its improvement.
