摘要
本文采用自相关分析法对内蒙古大兴安岭北部根河流域的相依性进行分析，结果表明，根河年径流相依性弱，这一特性的现实意义在于它揭示了该地区冻土对河川年径流的作用。同时也反映出森林的变化可以削弱年径流之间的关系。
The article analysed the annual runoff correlation of Genhe drainage area,which lies north of Daxinganling forest district,Inner Mongolia.It concluded that the correlation is not significant,and that forzen soil can affect the annual runoff.The relationship that forest changes can lessen the annual runoff was also revealed.
