该文研究黄土区以小流域为尺度的暴雨径流泥沙规律，为该地区林业生态工程建设和林业生态工程效益评价提供理论依据．该文以森林水文的较大研究尺度流域综合试验为出发点，在晋西黄土区小流域分类的基础上，选择了具有代表性的典型小流域１１个，对这些小流域进行了３～８ａ的定位观测，获得了１３１场暴雨产流和产沙资料．在分析这些资料的基础上，系统地研究了降雨、土壤入渗、流域产流、汇流及输沙的理论与方法，获得精度较高、适用性较强的流域径流、泥沙统计模型和数理模型．
This paper studies the law of heavy rain-runoff-sediment in the small watershed on the Loess Plateau, which provides the theoretical basis for the evaluation of the forestry ecological engineering construction and forestry ecological engineering in this area. Based on the comprehensive study of watersheds on a larger scale of forest hydrology, based on the classification of small watersheds in the loess area of western Shanxi, 11 typical small watersheds were selected, and 3 ~ 8a Positioning observation, access to 131 field runoff and sediment yield data. Based on the analysis of these data, the theories and methods of rainfall, soil infiltration, runoff generation, confluence and sediment transport are systematically studied, and the runoff and sediment statistical models and mathematical models with high accuracy and applicability are obtained model.
