中文摘要：
对天宝岩国家级自然保护区3种典型森林类型内粗死木质残体（CWD）的持水量进行研究。结果表明,柳杉（Crytomeria fortunei）林内CWD的持水量最低;不同森林类型各类CWD的水分蓄持能力不同,猴头杜鹃（Rhododendron simiarum）林内以倒木〉枯立木〉树桩,长苞铁杉（Tsuga longibracteata）林和柳杉林内为枯立木〉倒木〉树桩;CWD有效持水量和自然含水率随CWD腐烂程度增加呈上升趋势。
英文摘要：
The natural moisture content and effective water holding capacity of coarse woody debris（CWD） in three typical forest ecosystems in Tianbaoyan National Nature Reserve were studied.The results showed that the water holding capacity of CWD was the lowest in the Crytomeria fortunei forest;the water holding capacity was in order as fallen treesnagsstumps in Rhododendron simiarum forest,and snagsfallen treestumps in Tsuga longibracteata and Crytomeria fortunei forests.The effective moisture holding capacity of CWD increased with decay class of CWD increment,as well as the natural moisture content of CWD.
