| 摘 要： | 对天宝岩国家级自然保护区不同海拔长苞铁杉林粗死木质残体(coarse woody debris,CWD)的直径、数量、体积、高度及腐烂等级的分布特征进行对比研究.结果表明:(1)不同海拔的CWD主要分布在0-20 cm的小径级范围,数量和体积随径级的增加呈下降趋势;(2)海拔对倒木数量分布有极显著影响(df=2,P=0.006),倒木的数量随海拔上升而减少;枯立木的数量、体积随海拔的上升而增加;(3)不同海拔CWD主要分布在0-5 m高度级,且此高度级内CWD的数量分布随海拔的下降而增加;(4)倒木数量在不同腐烂等级上的分布差异显著(df=4,P=0.033). |

| Abstract: | The comparative study on the diameter,number,volume,height and decay class distribution of coarse woody debris(CWD) at different elevations in Tianbaoyan national nature reserve was conducted.The results were as follows:(1) Tsuga longibracteata forest was mainly composed of small-diameter-class CWD at different elevations,the number and volume of CWD decreased with the increase of diameter;(2) the elevation significantly affected the number of fallen trees(df=2,P=0.006),the number of fallen trees decreased ... |
