摘　　要：以EOS/MOD IS及TM/ETM卫星资料为主要数据源,对广西生态质量气象评价指标中的植被覆盖指数、水体密度指数、土地退化指数及灾害指数4个指标信息的提取进行了方法研究,并结合地面气象观测资料,以2008年第一季度为例以地市级为评价单元进行了广西生态质量气象评价,其结论对广西生态省建设工程及北部湾经济区的发展具有客观、科学的指导意义。Using the satellite data of EOS/MODIS and TM/ETM as the main data sources, this paper studies on the information extraction of indexes, including index of vegetation coverage, index of water body density,index of soil degradation and index of disaster, and then are applied for the meteorological evaluation of Guangxi ecological quality in the first season of 2008 combined with the meteorological data. The results are scientific, which have instructional meaning for the ecological engineering of Guangxi and the development of economic zone of North Gulf.
