| 摘 要： | 对龙陵县三江口国有林场中不同林分类型凋落物的储量、持水量、持水率和吸水速率进行了研究。结果表明:不同林型的凋落物贮备量有所差异,难被微生物降解的云南松林凋落物贮备量最大(2.66 kg/m2),其次是西南桦林(2.03 kg/m2)、旱冬瓜林(1.97 kg/m2),最小的是栎类林(1.81kg/m2)。旱冬瓜林(落叶阔叶林)的最大持水率最高,其次是西南桦林(落叶阔叶林)和栎类林(落叶阔叶林),云南松林(常绿针叶林)最低。

| Abstract: | Characteristics of litter from different forest types in Sanjiangkou state-owned forest farm of Longling County,including litter amounts,water holding capacity,water holding rate and absorption rate,have been studied. The results show that stockage of forest litter in different forest types is different,the largest stockage of forest litter is Pinups yunnanensis forest（ 2. 66 kg /m-2）,followed by Betula alnoides（ 2. 03 kg /m-2） and Alnus nepalensis forest（1.97 kg/m-2）,and the least stockage of forest litter is oak forest（ 1. 81 kg /m-2）. By contrast,the largest water holding rate of litter is A. nepalensis forest,followed by B. alnoides forest and oak,and the least water holding rate is P. yunnanensis forest. |
