黄河支流延河在2013 及1977 年7 月发生极端暴雨事件,但由于所处时间流域下垫面的
差异,暴雨的灾害表现迥异。论文比较分析延河流域2013 和1977 年7 月暴雨的降雨量、强度、
频率及其水沙变化特征,讨论了产生灾害不同的主要原因。结果表明:2013 年7 月延河流域降
雨总量、笼罩面积、降雨强度、暴雨频率均大于1977 年,而日最大径流量、最大输沙量、最大含沙
量、洪峰流量、峰值沙量、高含沙量历时却低于1977 年。2013 年延河流域暴雨灾害以地质灾害
为主,1977 年则以河道洪水灾害为主。退耕还林(草)工程实施后流域内植被大面积恢复,导致

Other Abstract

Yanhe River Basin suffered from rainstorm events in July 1977 and 2013. However,
the disasters showed different features due to the changes of underlying surface condition. This
paper investigated the amount, intensity and frequency of these two rainstorm events and
analyzed their relations with the runoff and sediment variations in the Yanhe River Basin. The
results showed that the amount, intensity, frequency of the rainstorm in 2013 were all higher
than those in 1977. However, the maximal daily runoff, maximal daily sediment, maximal daily
sediment concentration, peak runoff discharge, peak sediment discharge and the duration of
high sediment concentration in 2013 were all lower than those in 1977. The disasters in July
2013 were mainly caused by landslide and debris flow, while the disasters in July 1977 were
mainly caused by flood. Large-scale vegetation rehabilitation in the Yanhe River Basin after the
launch of“Grain for Green”program, which has changed the processes of runoff sediment,
was the main reason of the different results of the disasters.
