宝泉岭水文站上游洪水地区组成分析

Composition Analysis of Flood Area on Upper Baoquanling Hydrological Station

梧桐河是松花江左岸一级支流,流域面积4516km^2,其支流自上而下有细鳞河、石头河、鹤立河等。梧桐河干流上仅有一处水文站即宝泉岭水文站,集水面积2750km^2,关门嘴子水库坝址位于该水文站以上的梧桐河干流,集水面积1 846 km^2,为了满足关门嘴子水库设计的要求,文章分析了宝泉岭水文站控制断面以上洪水地区组成,通过分析计算得到满足关门嘴子水库设计要求的设计洪水成果。

The Wutong River is a branch of grade one on left bank of the Songhua River with the watershed area of 4516 km2, down the branches in order is the Xilin river, Shitou river and Heli river, etc,. The Baoquanling Hydrological Station, the only one hydrological station on the main stream of Wutong River, its collection area is 2750km2 ; the dam site of Guamenzuizi reservoir is located on the main stream of Wutong River on the upper hydrological station with the collection area of 1846km2. In order to meet the design demands of Guanmenzuizi reservoir, the flood area composition on the upper control section of Baoquanling Hydrological Station was analyzed in the paper, by analyzing and calculating, the design flood results were obtained to meet the design demands of Guanmenzuizi reservoir.
