摘要
根据昌图县工业园区发展规划,拟建一座人工湖,设计并计算人工湖需水量,结合实地调查,选取北洼子与王家油房两座水库为水源。因地区缺乏实测径流资料,采用参数等值线法计算北洼子水库与王家油房水库多年平均及75%保证率下的来水量,根据水库调节方法与原则,进行两座水库供水调节计算,根据水库实际供水量,以定供需,确定人工湖用水量,从而为人工湖设计提供有力的保证。
According to Changtu county industrial park development,an artificial lake will be built,whose capacity is needed to design and calculate.In the paper,combined with field surveys,two reservoirs were selected to supply water,which is respectively Beiwazi reservoir and Wangjiayoufang reservoir.Due to lack of area measured runoff data,the parameter contour method was applied to calculate the inflow between annual average rate and 75% guaranteed rate.According to the methods and principles of regulating reservoir,the two reservoirs supply adjustment calculation is concluded.Referred to the actual water supply of reservoirs,make sure the capacity of artificial lake determined by water supply and demand,which can provide a stong guarantee for the design of the artificial lake.
