摘要
Land cover is one of the important research fields of global change and regional sustainable development. High quality of basic data is the fundamental guarantee of reliability of production of science research. In order to evaluate accuracy of the land cover remote sensing mapping, a field survey was carried out in Hulun Buir in east Inner Mongolia and information from 190 sampling sites was collected. The results from verification show that overall accuracy of data based on 190 sampling sites reaches 84.21%. The incorrect classification cases mainly include that: 1) bottomland of river and lake was interpreted to marsh; 2) irrigable land was interpreted to paddy field; 3) meadow grassland interpreted to typical grassland; 4) typical grassland interpreted to desert; and 5) forest interpreted to grassland.
