摘要 以中国南方地区为研究区域,基于南方典型流域VIC模型的水文参数率定结果,运用多元逐步回归的方法分析了VIC模型水文参数与气候、土壤、地形地貌和植被因子之间关系,构建了中国南方地区VIC模型水文参数网格化公式,并对其进行了验证。结果表明,所建的南方地区VIC模型水文参数网格化公式均通过了显著性水平5%下的F检验,在验证流域上的应用效果较好,具有较高的模拟精度,为VIC模型在资料稀缺地区的应用提供了有力的技术支撑。 Taking southern region of China as an study area, based on the hydrologic parameters calibration of variable infiltration capacity (VIC) model in typical basin, multiple stepwise regression method is applied to analyze the rela tionship between hydrologic parameters of VIC model and climate, soil, topography and vegetation characteristics. And then a modification for hydrologic parameter gridding formulas of the VIC model is established. The result shows that the gridding formula has higher precision and passes F-test at a significance level below 5%; it has good application effect in
