对桤木人工林的林冠层截留效应、枯落物层蓄水特征以及土壤水分物理性质的测定与研究。结果表明：观测期内穿透雨占总降水量的80.96%，林冠截留量占总降水量的16.98%，树干茎流量占总降水量的2.07%；林下枯落物累积为7.86 t•hm-2，其最大持水量为2.48mm，半分解层的最大持水量是未分解层的5.80倍；0-45cm层土壤最大持水量为198.86mm，K10值为0.72。

Through mensuration and research of the Interception by Canopy,Litter Moisture Content Impress and Soil water physical characteristics of Alnus cremastogyne Burli.

结果表明：观测期内穿透雨占总降水量的80.96%，林冠截留量占总降水量的16.98%，树干茎流量占总降水量的2.07%；
The result shows: of the total precipitation,the penetrable rain take 80.96% ,the interception by canopy take 16.98%,the bole caudex flux take 2.07%;

林下枯落物累积为7.86 t•hm-2，其最大持水量为2.48mm，半分解层的最大持水量是未分解层的5.80倍；0-45cm层土壤最大持水量为198.86mm，K10值为0.72。
The litter storage is 7.86 t•hm-2, the maximum moisture content is 2.48mm. The half decomposable layer maxium moisture content is 5.80 times of the undecomposable layers.The 0-45cm layer soil maximum moisture content is 198.86mm,the K10 value is 0.75.
