摘要
对长江三角洲森林生态系统定位站的北亚热带毛竹林干流影响因素—降雨量级和竹干胸径进行了观测研究。结果表明:毛竹林的干流与降雨量级、竹干胸径存在不同程度的相关性,干流量与降雨量级成正相关性,差异性极显著,干流率与降雨量级关系是:先正相关性后负相关性。而干流量与竹干胸径的关系比较复杂,当降雨量级较小或较大时,干流量与竹干胸径成负相关性,差异性极显著或显著;当降雨量级中等时,干流量与竹干胸径成正相关性,差异性显著。
Factors which consisted of rainfall grade and the diameter of bamboo influencing the stemflow of northern subtropical bamboo forests were observed and studied in the Yangtze River delta forest located ecosystem station.The results showed that the stemflow（rate） of bamboo forest was correlated with different degree of rainfall class,the diameter of bamboo,The stemflow had positive relevance to rainfall grade,the difference was most noticeable,while the stemflow rate had positive relevance to small rainfall grade and had negative relevance to middle and large rainfall grade.The stemflow had negative relevance to the diameter of bamboo when rainfall grade was small or large,and the difference was most noticeable or noticeable;The stemflow had positive relevance to the diameter of bamboo when rainfall grade was middle,and the difference was noticeable.
