基于RS&GIS的河北省生态质量气象评价

The Meteorological Evaluation of Ecological Quality of Hebei Based on RS & GIS

采用卫星遥感(RS)和地面监测、统计相结合的各项数据,选取湿润指数、植被覆盖指数、水体密度指数、土地退化指数及灾害指数为评价指标,对河北省及各市2001-2007年进行生态质量气象评价。结果表明,7年间河北省整体气象生态质量一般,但时空差异较大,各指标地区表现也不一致。

The quality of eco-meteorological of Hebei province from 2001 to 2007 was evaluated using satellite remote sensing combined with the dates from monitoring and statistics, selecting the vegetation index, index of water density, land degradation and hazard index for evaluation. Results shows that the score is normal in 7 years. However, large differences are in time and space and the performance of the index area is also inconsistent.
