| 摘 要： | 林冠是森林生态系统影响降雨的第一作用层。降雨经过林冠后,被进一步分为林内穿透雨、树干径流和林冠截留。林冠的截留作用不仅改变了降雨的空间分布格局,而且影响了与之相关的物质循环和能量转换(李振新等,2004)。目前,已有大量文献报道我国热带雨林(周光益,1997;张一平等,2003)、亚热带常绿阔叶林(崔向慧等,2006)和温带落叶阔叶林(万师强等,1999)的林冠截留特征。我国主要森林生态系统的林冠截留率为11.40%～

| Abstract: | Throughfall, stem flow and rainfall were measured from Jul. 2009 to Sep. 2010 in an evergreen broad-leaved secondary forest in Yangdongshan, North Guangdong. The characteristics of rainfall and canopy interception of the forest were analyzed. The results indicated that the total rainfall was 2 362.6 mm during the experimental period. Rain days with 0.0-5.0 mm daily rainfall accounted for 55.2% of all rain days, but the rainfall accounted for only 8.0% of the total rainfall. However, rain amount of 10.0-25.0... |
