The major findings of this research can be summarized as follow:1 The comparison of USPED model-estimated amounts of soil erosion based on four different scales of DEMs (1:250,000, 1:50,000, 1:10,000, and 1:5,000) indicates that 1:50,000 -scale DEM is almost as good as higher-resolution DEM data in providing needed topographic information for assessing soil erosion, whereas 1:250,000-scale DEM underestimates soil erosion mainly because rill erosion and sheet erosion are greatly underestimated.2 Since precipitation is the most important forcing factor for soil erosion, the accuracy of soil-erosion estimates understandably relies on the adequacy of spatially distributing point-observed precipitation data.
取得的主要成果如下:(1)基于四个尺度(1∶250,000,1∶50,000,1∶10,000,and 1∶5,000)的数字高程模型和USPED模型计算的土壤侵蚀结果对比表明,1∶50,000的数字高程模型与更高分辨率数字高程模型提供了几乎一样的用以估算土壤侵蚀所需的地形信息,而1∶250,000的数字高程模型,由于过低的估算了细沟侵蚀和片蚀,从而过低的估算了土壤侵蚀的总量。
