摘要
黑龙江省西部半干旱区为我国重要的粮食生产基地,为了摸清该区降雨入渗规律,以增加降雨入渗,提高降雨利用率,减少水土流失。采用人工降雨的方法,在黑龙江省甘南县国家863试验基地进行了土壤水分入渗性能研究。在此基础上,分别采用Horton、Philip和Kostiakov入渗公式对该区的降雨入渗进行了模拟,探讨了入渗公式在该区的适用性。结果表明,3个模型在黑龙江省西部半干旱区的适用性依次为Kostiakov、Horton和Philip。同时说明Kostiakov入渗公式尽管从模型结构分析来看,不符合垂直入渗条件,但对该区降雨条件下的入渗规律模拟较为准确。
The west semiarid region Heilongjiang province is a important base for grain production in our country. In order to make the regularity of infiltration clear for rainwater use rate promotion and erosion control, the experiment of infiltration characteristics of soil was conducted by means of artificial rainfall in Gan＇nan county, the national 863 project experiment base. And the precipitation were simulated by 3 famous infiltration models of Horton, Philip and Kostiakov, the applicability of the models were discussed. The results show that the order of 3 models＇ applicability in the west semiarid region Heilongjiang province were Kostiakov, Horton and Philip. And although it is not suitable to vertical infiltration condition from the analysis of the model itself, Kostiakov model was more accurate for infiltration simulation under rain condition in the region.
