摘  要:
对不同月份叶面积指数时空分布及其对林冠截留、透流及干流的影响进行观测研究。结果表明:2~8月份叶面积指数一直在递增,9~1月份叶面积指数一直在递减,8月份叶面积指数达最大值7.5,2月份叶面积指数达最小值为3.1。各月林冠截留、干流与叶面积指数呈正相关性,透流与叶面积指数呈负相关性。当降雨量小时,随叶面积指数的递增则林冠截留、干流递增缓慢;当降雨量和降雨强度较大时,随叶面积指数的递增则林冠截留、干流递增加快。

摘  要:
Distribution of time and space of leaf area index(LAI)in different months and its influence on canopy interception,throughfall and stemfall were observed and studied.The results showed that LAI was increasing from February to August,LAI was reducing from September to January,LAI maximal value(7.5)in August,LAI minimal value(3.1)in February.In every month canopy interception and stemfall had positive relevance to LAI,throughfall had negative relevance to LAI.Fllowing LAI increasing,canopy interception and stemfall increased slowly while rainfall was small,canopy interception and stemfall increased fast while rainfall and its intensity was large.
