关河水库流域降雨径流关系的研究
发布时间：2019-05-23 19:48
【摘要】：近年来,由于自然降雨减少,人类活动加剧,城市化进程加快,经济社会发展迅速,漳河上游流域内用水量大增,造成河道来水量锐减,水供需矛盾加剧。 关河水库流域错综复杂的水网和水流的不确定性,决定了关河水库流域的降雨径流的特点。本文主要针对关河水库流域的降雨、蒸发及径流的规律及降雨与径流之间的关系进行数据研究。通过1981-2010年的日降雨量的分析,得出平均每月的降雨量及平均每年的降雨量,并通过曲线直观的表现出来；通过30年每日的温度资料分析,得出平均每月、平均每年的的蒸发量,并进行比较；通过水库提供的30年每月库容变化等资料分析出平均每月、平均每年的径流量进行比较。然后进行降雨与径流之间的关系比较并分析结果。 通过分析得出关河水库流域降雨量与径流量均有下降的趋势,而蒸发量却逐步增加,径流量的大小不仅仅与降雨量的大小有关,还有蒸发、水库的调节、植被、下垫面等因素制约。
[Abstract]:In recent years, due to the decrease of natural rainfall, the intensification of human activities, the acceleration of urbanization and the rapid development of economy and society, the water consumption in the upper reaches of Zhanghe River has increased greatly, resulting in a sharp decrease in the incoming water volume and the aggravation of the contradiction between water supply and demand. The intricacies of water network and water flow in Guanhe Reservoir Basin determine the characteristics of rainfall and runoff in Guanhe Reservoir Basin. In this paper, the law of rainfall, evaporation and runoff in Guanhe reservoir basin and the relationship between rainfall and runoff are studied. Through the analysis of daily rainfall from 1981 to 2010, the average monthly rainfall and average annual rainfall are obtained, and the curve is intuitively shown. Through the analysis of daily temperature data for 30 years, the average monthly and average annual evaporation is obtained and compared, and the average monthly and average annual runoff is compared through the 30-year monthly reservoir capacity change and other data provided by the reservoir. Then the relationship between rainfall and runoff is compared and the results are analyzed. Through the analysis, it is concluded that the rainfall and runoff in Guanhe Reservoir Basin have a downward trend, but the evaporation is gradually increasing. The runoff is not only related to the rainfall, but also evaporation, reservoir regulation, vegetation. The underlying surface is restricted by factors such as the underlying surface.
