摘要：通过对长江三角洲城市森林生态定位站的北亚热带次生毛竹林林冠降雨再分配的观测研究,探讨了不同叶面积指数下场降雨林冠截留、透流和干流动态过程。结果表明:叶面积指数对小雨时林冠截留过程影响不大,对中、大雨时林冠截留过程影响显著;对透流雨和干流的影响主要表现在波峰值的大小和峰值形成时间上的差异;随叶面积指数的递增,则透流雨的峰值减小,形成时间滞后,而干流峰值显著增加,形成时间超前。
The rainfall redistributions by crown layer in bamboo forests in the urban forest ecological station in Yangtze River delta were monitored,the dynamic process of the canopy interception,throughfall and stemfall in different leaf area index were discussed.The results showed that the change of leaf area index effected the canopy interception not obviously at the light rain class and it was obvious at moderate and heavy rain class;it mainly embraced in the wave crest value and the formation time,with leaf area increasing,the wave crest value of throughfalls decreased,the formation time generally run behind,and the wave crest value of stemfalls increased,the formation time generally run beforehand.
