基于遥感的公路边坡生态环境健康评价研究进展

Research Progress of Ecological Environmental Health Evaluation of Highway Slope Based on Remote Sensing

与传统的监测方法相比,遥感技术具有高时效、受限少等优势,这些优势使得遥感技术在边坡生态领域成为重要技术手段。首先,阐述遥感获取的数据包括MODIS数据、Landsat TM数据等;然后对层次分析法、模糊数学评判法等评价方法进行表述;在此基础上,对植被覆盖率、土地利用/土地覆盖变化等影响因子进行总结;最后围绕公路边坡生态环境的遥感评价研究,提出存在的问题(解译信息程度不够,边坡生态研究少等)和研究展望。

Compared with traditional monitoring methods,remote sensing technology has advantages such as high time limitation,limited limitation.These advantages make remote sensing technology become an important technical means in the ecological field of slope.Firstly,the data of remote sensing acquisition include MODIS data,Landsat TM data,etc.And the traditional methods of analytic hierarchy process,fuzzy mathematics evaluation and so on;On this basis,the factors such as vegetation coverage,land use and land cover change are summarized;Finally around the highway side slope ecological environment and the traditional remote sensing evaluation studies,put forward the problems existing in(interpret information degree is not enough,less slope ecological health evaluation,etc.)and the research prospects.
