| 摘 要： | 对长江三角洲森林生态定位站的北亚热带毛竹林林冠截留作用进行了观测研究，结果表明：研究区毛竹林的林冠全年截留总量为171.7 mm，场均截留率为29.4%，有着较好的生态水文作用。不同雨量级、雨强级下，毛竹林林冠截留效果差异显著，在小雨量级、雨强级下，毛竹林林冠截留效果较好。毛竹林林冠截留量(率)与降雨量、降雨强度、降雨历时、叶面积指数、枝叶雨前干燥度存在不同程度的相关性，降雨历时对林冠截留量起重要作用，降雨强度对林冠截留率起重要作用。在已有的林冠截留模型基础上，引入叶面积指数变化动态加以改进，改进后的模型有更好的适用性。

| Abstract: | The canopy interception effects of northern subtropical bamboo forests were observed and studied in the Yangtze River delta forest located ecosystem station.Our result showed that the annual canopy interception amount was 171.7 mm,average canopy interception rate was 29.4%,which had better eco-hydrological effect.The canopy interception effects of bamboo forest were different markedly under the different rainfall level,rainfall intensities level,it had better interception effect under small rainfall level a... |
