曲阜九仙山小流域降雨径流关系变化分析

Analysis on the Relationship Between Rainfall and Runoff in Jiu Xianshan Watershed in Qufu

以曲阜九仙山小流域为例,收集了该流域2017—2019年的降雨、径流等实地观测数据,通过对该流域5个径流小区的降雨、径流和泥沙过程进行分析,阐述了流域径流在降雨过程中产生水土流失效应及内在机理,为小流域水土流失防治提供了理论依据。

This paper takes Jiu Xianshan watershed in Qufu as an example,collecting the field observation data,such as rainfall,runoff from 2017 to 2019.By analyzing the process of rainfall,runoff and sediment in 5 runoff plots in this watershed,the paper states the effect of soil and water loss and internal mechanism in the process of rainfall,providing the theoretical basis for the prevention and control of soil erosion in small watershed.
