清流河流域水文气象要素历史演变特征
Eevolution characteristics of history of hydrological and meteorological elements in Qingliu river basin
摘要
Abstract
Based on the observed data of precipitation ,temperature, pan evaporation and runoff from1961 to 2012 ,the paper usedstatistical analysis method to investigate the evolution characteristics of hydro -me-teorological element at different temporal scales for the QingliuRivercatchment .The results indicate thatin recent 50 years from 1961 to 2010 , the temperature in summerpresented insignificant risingtrendwhilean-nual and other seasonal temperature showed significant rising trend .However , temperature exhibited the-declining trend after 2007 .The precipitation in annual , summer and winter presented the increasing trend, but that inspring and autumnpresented the insignificant decreasing trend .The water surface evapo-ration presented the decrease trend in annual and the other three seasons except spring .The evaporation paradoxis obvious .The variation of runoff is generally in accordance with that of precipitation .Bothannual and seasonal runoff presented increasing trend whilerunoff in winter presented significant increasing trend.The correlation coefficientbetween runoff and precipitation is higher than 0.65.Therefore ,precipi-tation is a major driver of runoffvariation .It is necessary to pay sufficient attention to the impact of cli-mate change and especiallyprecipitationchange on water resources .关键词
