摘要:
我国是世界上水土流失最严重的国家之一,已成为我国的头号环境问题.以北京地区Landsat ETM和DEM为主要数据源,依据水利部颁布的《土壤侵蚀分类分级标准》(SL190-96),采用了第二次全国土壤侵蚀遥感调查中的多因素综合法,选取土地利用类型、植被覆盖度和坡度三个因子,对北京地区水土流失状况进行了快速监测,该方法简单易行,结果基本符合实际情况.
Abstract:
The soil erosion in China is very serious in the world,and the soil erosion has already become the No.1 environmental question.According to"the soil erosion classification grade criteria"(SL 190-96) issued by the Ministry of Water Resources,the multifactor comprehensive method in the second national soil erosion investigation based on remote sensing was adopted,and land use type,the fractional vegetation cover and slope were the three factors affecting soil erosion.The land use type and the fractional vegetation cover of Beijing area were derived from Landsat ETM image acquired on May 22,2002,and the slope of Beijing area was mapped from the 1:250 000 DEM.Therefore,the soil erosion state of Beijing area can be calculated and analyzed.The method is easy, and the mapped soil erosion result was consistent with the in situ investigation and the actual status.
