摘要
通过对分别位于北京山区和平原区两种地貌类型的2个开发建设项目新增水土流失预测的研究,提出了原地貌和扰动地表水土流失的预测方法。研究表明,新增水土流失的预测,主要是对原地貌和扰动地表土壤侵蚀模数的确定,确定时主要采用实测数据、类比法、水文资料查阅法以及模数修正法等。
Based on the study of extra soil erosion of two construction projects which were located in mountain areas and plain areas of Beijing respectively, the prediction method of soil erosion for original geomorphology and disturbed surface soil is proposed. It was shown that the prediction of extra soil erosion was mainly determined by the soil erosion modulus of the original geomorphology and disturbed surface soil. The experimental data, analogical method, hydrological data and modulus reserved are manly the methods when the soil erosion modulus are determined.
