| 摘 要： | 构建基于元胞自动机(CA)模型的分布式水文模型,模拟小流域内降雨径流过程。从元胞状态、转换规则与时间步长3个方面扩展普通CA模型,包括5个子状态、5个元胞系数及两条转换规则,并实现模型与GIS的集成。以黄土高原岔巴沟流域的降雨径流观测数据对模型进行了验证分析。试验结果表明,确定性系数、峰现时差与洪峰误差3个评价指数都达到一定精度,实现了流域内径流过程的可视化。结合CA模型与GIS技术可以较为有效地模拟流域次降雨径流过程,模型在该试验区是基本适用的。

| Abstract: | A distributed hydrological model based on cellular automata(CA) is developed to simulate the rainfall-runoff process in small sized watersheds.The distributed model is built by extending cellular states and transformation rules,as well as the time step in the general CA model.The model consists of five substates with five cellular parameters and two transformation rules,and is fully integrated with a geographic information system(GIS) platform.The model is validated using the observed rainfall-runoff data f... |
