通过对南瓮河国家级自然保护2012年6月15日—9月25日落叶松林降雨的观测,研究了穿透雨、树干径流和树冠截留之间的关系,结果表明：黑龙江南瓮河国家级自然保护区观测期间总降雨量为216.6 mm,穿透雨为121.6 mm,占总降雨量的56.2%,树冠截留量为62.5 mm,占总降雨量的28.8%,径流量为32.5 mm,占总降雨量的15%；随着降雨量增加,穿透雨和径流量增加,树冠截留量减小；随着冠层减少,穿透雨和径流量增加,树冠截留量减少；树干径流量取决于降雨量、降雨强度和树冠特征。
通過對南甕河國傢級自然保護2012年6月15日—9月25日落葉鬆林降雨的觀測,研究瞭穿透雨、樹榦徑流和樹冠截留之間的關繫,結果錶明：黑龍江南甕河國傢級自然保護區觀測期間總降雨量為216.6 mm,穿透雨為121.6 mm,佔總降雨量的56.2%,樹冠截留量為62.5 mm,佔總降雨量的28.8%,徑流量為32.5 mm,佔總降雨量的15%；隨著降雨量增加,穿透雨和徑流量增加,樹冠截留量減小；隨著冠層減少,穿透雨和徑流量增加,樹冠截留量減少；樹榦徑流量取決于降雨量、降雨彊度和樹冠特徵。

The rainfall of larch forest was observed in Nanwenhe National Nature Reserve from June 15,2012 to September 25,2012 .The relationship among the throughfall,runoff and canopy interception were studied.Result shows that the total rainfall is 216.6 mm.The throughfall which is 121.6 mm constitute 56.2% of the total rain-fall.The canopy interception which is 62.5 mm constitutes 28.8% of the total rainfall.The runoff which is 32.5 mm constitutes 1 5% of the total rainfall.Throughfall and runoff increase with the increase of the rainfall.The can-opy decrease with the increase of the rainfall.With the reduction of the canopy,the canopy interception decrease. The runoff depends on rainfall,rainfall intensity and canopy characteristics.
