汤旺河流域径流变化研究
Study of Runoff Variation in Tangwang River Basin
摘要
Abstract
Climate is an important factor in hydrologic cycle,it will directly affect the allocation of river basin water resources.In order to study the runoff variation of the Songhua River Basin under global climate warming,as a branch of the Songhua River,the Tangwang River is chosen as an object in this study.We use regression analysis method,Mann-Kendall test method and wavelet analysis method to investigate the runoff data from 1956 to 2013 of Chenming hydrologic station.The results indicate that the runoff in a year shows a single peak.The maximum monthly runoff turns out in August;the runoff in summer takes 57％ of the total annual volume.The annual runoff shows an insignificant decreasing trend;the decrease range is 2.33 billion cubic meters/10a.Annual runoff has 3 cycle periods of time scale.According to the main period of 18 years,we indicate that there will be a wet season in the future.关键词
