摘要
本文针对在产流理论方面形成的“蓄满型”与“超渗型”两种不同的学术观点 ,从不同径流成分的产流机制、各种产流机制不同的组合而形成的产流类型 ,以及产流机制的统一性和相互转化关系等方面不仅论证了在同一地区超渗产流与蓄满产流方式将随着降雨特性和下垫面条件的变化 ,而相互转化、相互补充 ,而不是相互对立的辩证关系 ;而且阐明了超渗地表径流与超渗产流模型、饱和地表径流与蓄满产流模型是不同的物理概念。
It is known that there exist two runoff yielding patterns,one is that the runoff yields after the moisture content in aeration zone of the soil reached up to the field moisture capacity,another is that the runoff yields at the time when the rainfall intensity is greater than the infiltration intensity of the soil. In this paper,the writer described that there are transformation and replenishing of water between the two patterns,and pointed out in conclusion that any one of the two patterns may be used in the same basin,so far as the correctness is concerned,that is,whether it should be used or not,it will mainly depend on the agreement degree in the runoff and in the runoff hydrograph between these which are measured at the outlet of the whole basin and those which are obtained by computation based on the runoff yielding pattern used,this is the sole criteria for choosing correctly the runoff yielding pattern.What has higher precision has to be chosen.
