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。
This study chose the middle and southem 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.
