Recent Advances and Research of TOPMODEL
【摘要】 TOPMODEL是一种基于物理过程的半分布式水文模型,该模型以计算地形指数的空间格局来反映流域饱和缺水量的空间分布,物理意义明确。介绍了TOPMODEL的原理,以及地形指数的意义和计算方法,讨论了TOPMODEL与GIS集成,以及模型尺度等热点问题。
【Abstract】 TOPMODEL is a semi-distributed physical model to simulate the hydrological process.The model makes use of topographic information and the spatial distribution of topographic index to represent the spatial variability to contributing of watershed saturation deficit.The structure of model is distinct.It shows the TOPMODEL theory,signification of topographic index and the computing method.In the end,scale TOPMODEL and integration of watershed hydrologic model with Geographic Information System were discussed.
