摘要： 对秦岭巴山冷杉林粗死木质残体的研究表明：1)林内粗死木质残体的现存量为15.848t·hm-2，平均死亡增枯量1.877t·hm-2·a-1，平均分解量1.310t·hm-2·a-1，周转时间约为12.09年；2)粗死木质残体在碳素和养分的保持方面具有一定作用，在野生动植物生境构成中的作用较大。

Abstract: A study of coarse woody debris (CWD) in an Abies fargesii forest in the Qinling Mountains showed that, 1) the total amount, the annual average increment and the decomposition rate of CWD in the forest were 15.848t·hm-2, 1.877 and 1.310 t·hm-2·a-1 respectively. 2) CWD played a less important role in maintaining carbon and nutrients and a relatively important role in the formation of habitats for the wild life.
