重点阐述国内自主研发的水循环综合模拟系统（ HIMS，hydro?infomatic modelling system）降雨产流模型的新发展。 HIMS原有产流计算主要是基于降雨动态入渗机制的LCM模型，该产流模型是通过大量野外小流域观测试验提出的经验模型。为进一步揭示其物理机制， HIMS研究团队基于物理机制清晰的Green?Ampt模型，提出了新的GAF模型。从理论上通过GAF模型可以直接推导出LCM模型，以及SCS?CN模型，并证明了LCM模型是GAF模型的高精度幂指数近似，而SCS?CN模型是GAF模型的倒数线性近似解简化；通过对GAF模型解析解的深入分析，提出了两参数SCS?CN修正模型，使之包含了雨强的影响。

This paper focuses on the new developments in the rainfall?runoff model of the hydro?informatic modeling system (HIMS). The original rainfall?runoff model of HIMS is the LCM model, which is based on the dynamic rainfall infiltration mechanism and has been built through a large number of field observation experiments in small watersheds. In order to further understand the physical mechanism of the LCM model, the HIMS research team proposes a new GAF model based on the Green?Ampt model whose physical mechanism is clear. Theoretically, the LCM model and the SCS?CN model can be directly derived from the GAF model, it is proven that the LCM model is a high?accuracy power exponent approximation of the GAF model, and that the SCS?CN model is a simplification of the reciprocal linear approximation solution of the GAF model. Based on deep analysis of the analytical solution of the GAF model, a modified SCS?CN method with two new parameters, which considers the impact of rainfall intensity, is proposed.
