河西走廊地处西北内陆河流域,由于气候干旱、风大沙多,风沙对水利工程的填埋淤积非常严重。在对河西走廊水利工程风沙危害现状全面调查的基础上,按风沙危害成因,将危害类型划分为以风沙流为主、以河道水力输沙为主和以沙丘前移为主的三种形式,并分别以榆林河水库及干渠、双塔水库和解放村水库为例,研究建立了不同危害类型的防治措施配置体系,以期延缓风沙对当地水利工程的填淤过程。
Hexi Corridor is located in the northwest inland river basin, due to the arid climate, wind and sand, wind and sand filling of the water conservancy project siltation is very serious. Based on a comprehensive survey of the status quo of wind and sand hazards in Hexi Corridor water conservancy project, according to the causes of sandstorm damage, the types of hazards are classified into three types, which are mainly sandstorm flow, hydraulic sand conveyance and predominant sand dune advance. Taking Yulinhe reservoir, main canal, Shuangta reservoir and Jiefang village reservoir as examples, the disposition systems of different hazard types were set up in order to delay the filling process of wind-blown sand to local water conservancy projects.
