• Research manifests that : ( 1 ) allocation in the year of precipitation is very uneven , and yearly precipitation is different in great scope , negative anomaly of precipitation appear concentratly in the 1990s , the precipitation in the 1990s decreased in different degree ; ( 2 ) close positive correlation exists between runoff and precipitation , runoff is abundant in the year with prolific precipitation , and generally in the year with scarce rain the volume of runoff is not enough ; ( 3 ) there is 20 % margin in their changes amplitude , this mainly resulted from high frequent human activities
  结果表明： ( 1 )流域内降水年内分配极其不均；年际变化剧烈，进入90年代后降水负距平集中出现， 20世纪90年代降水较多年均值有较大程度的减少； ( 2 )流域内河川径流与降水之间存在密切的正相关关系，降水量多的年份，河川径流丰富，反之较枯； ( 3 )河川径流积极响应降水的变化，然而河川径流变化幅度却比降水变化幅度大20 % ，这个偏差主要是由于频繁的人类活动的干扰造成的。
