| 摘 要： | 雅砻河是雅鲁藏布江重要支流之一,依据雅砻河某水文站提供的水文资料,运用基流分割法计算出雅砻河流域以地下水补给为主,其次为降水和冰川融水补给.通过多元回归分析表明,该流域消融期径流量的变化与温度、降水相关性极高:温度升高,降雨增多,径流量相应的增加,反之则反,气温对径流起着积极主导作用；非消融期径流与温度、降水关系不密切...

| Abstract: | The Yalong river is main tributary of Yarlung Zangbo river.Based on the hydrology data supplied by hydrometric station of Yalonghe river,the main recharge of Yalonghe river is derived from groundwater,followed by precipitation and glacier through the base flow separation calculation method.Analysis of multiple regression shows the runoff change has closely related with temperature and rainfall: rainfall and runoff increase with temperature rising and vice versa,temperature has positive effect on runoff in ablation period;runoff change has no significantly related with temperature and rainfall in non ablation period. |
