鞍山市生态资源与环境质量的遥感数据分析

利用美国陆地卫星资源LandsatTM遥感监测数据,参考相关图件,进行解译判别,监测鞍山市区及各县区土地类型、土地退化类型,并结合水资源的调查结果,对鞍山市生态环境质量进行评价,分析结果表明,鞍山市全境存在一定程度的土壤侵蚀现象,但基本上为微度侵蚀,重度侵蚀和中度侵蚀面积较小;鞍山市区和台安县生态环境状况指数一般,较适合人类生存,岫岩县和海城市生态环境状况指数良好,生物多样性较好,基本适合人类生存。

A Remote-sensing-data-based Analysis of Anshan Ecological Resources and Environmental Quality

The U.S. Landsat TM resources remote sensing data were adopted, with related maps for reference, to interpret, decide and monitor the land type and the land degradation type in the Anshan urban districts and its counties and suburban districts, and to make an evaluation for the quality of the Anshan ecological environment in the light of the result of the investigation into water resources. The result of analysis showed that soil erosion exists to certain degrees all over the Anshan region but the soil erosion roughly belongs to slight erosion and the area which is severely and moderately eroded is relatively small; the indexes of the ecological environments in the Anshan urban districts and Taian County belong to average, which means the two places are suitable for human living; and both Xiuyan County and Haicheng City present good indexes of ecological environment, which means the two places are of good bio-diversity and suitable for human living.
