从农田土壤水分平衡方程出发,综合考虑了农田水分的主要收支项,特别是对水分渗漏量估算进行了必要的改进,建立了旱地农田土壤水分的动态模型。
Soil water balance of grassland in gully regions on the Loess Tableland in various hydrological years was simulated numerically with simulated rainfall.
采用人工降雨的试验方法,对黄土高原沟壑区荒草坡地不同水文年土壤水平衡进行了数值模拟,结果表明:当植被覆盖率较高时,WAVES模型可以应用于荒草坡地土壤水平衡的模拟;土壤储水量的模拟结果与实测值趋势很吻合,但有关参数的取值还有待于进一步研究;荒草地土壤水分收支基本平衡所需的雨季降雨量和年总降雨量分别为507。
