摘　　要：为了解猫儿山常绿阔叶林木质残体储量特征,以猫儿山常绿阔叶林1 hm^(2)样地为研究对象,调查和分析不同类型、分解等级和径级木质残体储量特征。结果表明,猫儿山常绿阔叶林木质残体数量为404根/公顷,其中倒木数量为180根/公顷,枯立木数量为67根/公顷,细木质残体数量为157根/公顷。木质残体总储量为57.11 t/hm^(2),其中粗木质残体储量为41.54 t/hm^(2),细木质残体储量为15.57 t/hm^(2);倒木是木质残体储量的主要来源,占木质残体总储量的61.52%。分解等级为Ⅲ和Ⅳ级的粗木质残体储量均较高,分解等级为Ⅴ级的细木质残体储量最高。10~<20 cm径级粗木质残体储量最高。猫儿山常绿阔叶林木质残体储量在相同纬度地区处于较高水平。To understand storage characteristics of woody debris in forest ecosystem of Mao'er Mountain evergreen broad-leaved forest,1 hm^(2) smaple plot in Mao'er Mountain evergreen broad-leaved forest was selected as research object to investigate and analyze storage characteristics of woody debris in different types,decomposition classes and diameter classes.Results showed that total number of woody debris in Mao'er Mountain evergreen broad-leaved forest was 404 individual/hm^(2),with 180 individual/hm^(2) logs,67 individual/hm^(2) snags and 157 individual/hm^(2) fine woody debris.Total woody debris storage was 57.11 t/hm^(2) with coarse wood debris storage of 41.54 t/hm^(2) and fine wood debris storage of 15.57 t/hm^(2).Logs were main source of woody debris,accounting for 61.52%of total woody debris storage.Coarse woody debris with decomposition classes ofⅢandⅣhad higher storages,while fine woody debris with decomposition class ofⅤhad the highest storage.Coarse woody debris in 10-<20 cm diameter class had the highest storage.Woody debris storage of Mao'er Mountain subtropical evergreen broad-leaved forest was at relatively high level compared with other areas at the same latitude.
