Abstract
Based on the precipitation,air temperature and runoff records out of Tailan Hydrological Station from 1957 to 2010,various hydrological and meteorological factors were analyzed by multiple mathematical statistics methods. The results of analysis demonstrate that precipitation generally had a rising trend with increasing interan-nual change amplitude and basically stable long-time average annual value;air temperature generally had a rising trend with remarkable dropping trend and rising trend before and after 1980 respectively;runoff had notable rising trend. It is preliminarily concluded that air temperature is the dominant factors influencing runoff in spring;while precipitation and air temperature jointly affect the runoff during summer,autumn and winter.关键词
