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。

结果表明：土体厚度和表层有机质含量与地形因子之间有着显著相关性；建立的线性回归模型分别能解释土体厚度、表层有机质含量空间变异的32.2%和35.3%；依据该模型预测的土体厚度和表层有机质含量具有较高的准确度，并能制图表达土壤属性在空间上的自然连续性。

measurement of image matching, scanned topographic map, features with symmetric figure, automatic extraction

二值图象的形态学 MM匹配量度 [1 ]不能用于曲线图象的匹配，因为曲线的尺寸较小从

The measurement takes account of accumulation of discrepancy signals, distribution of discrepancy signals, and treatment of preternatural discrepancy signals. Based on the measurement, this paper presents, at the same time, a new algorithm for extracting features with symmetric figure on scanned topographic map.

前者匹配效率高，稳定性好，对图象的非本质的变化不敏感；而后者利用图象中的所有信息，所以区分不同图象的能力强，精度高，特别是它能在十分复杂的图象环境下(此时很难甚至不可能使用特征匹配法)有效地工作。
