摘要
晋西黄土丘陵沟壑区坡面径流预报模型为R=[(P—z)—FTL-u]T_pC。本模型是为了满足晋西黄土丘陵沟壑区水土保持规划的要求而建立的。模型建立以晋西离石王家沟为试验研究区,考虑了降雨、植被拦截、土壤入渗、耕作方式、土地利用以及表土结皮等因素的影响,所用的资料均是在天然或人工模拟降雨条件下获得的。这一模型可用于预报晋西黄土丘陵沟壑区坡面每次降雨所产生的径流总量。据检验,模型变量设置基本合理,具有良好的预报精度。
The prediction model of runoff on slope surface of gullied rolling loess area in west Shanxi is R=[(P-Z) - FTLu]TPC. The model is set up for meeting the requirement of planning the soil conservation of gullied rolling loess area in west Shanxi. The model is built based on the experimental plot in Wangjiagou, Lishi. west Shanxi, considering the factors of precipitation, vegetation, infiltration, way of tillage, land utilization and the coating effect of surface soil. All the data is obtained under conditions of natural or artificial precipi-tation. Total volume of runoff produced by each rainfall on the slope surface of gullied rolling loess area in west Shanxi can be predicted by the model. According to that variables used in the model is reasonable and the precision of prediction fairly good.
