摘要
利用蘸水法分析了在西双版纳普文山地营造的西南桦、山桂花人工纯林的乔、灌、草、枯落物等 4个层次的最大持水能力 ,以及测定了这两种人工林土壤的蓄水能力 ,得出西南桦全林最大持水量为 6 2 93mm ,山桂花林为 6 7 94mm。于此对西双版纳种植的西南桦、山桂花人工林在水源涵养功能和作用上有所了解。
The maximum moisture retention power of four layers, namely tree, shrub, herb and litter of pure stands of Betula alnoides and Paramichelia baillonii established at Puwen, Xishuangbanna were analyzed using dipping plant method. The water storage capacity of soil of these plantations were determined as well. The maximum water storage capacity of Betula alnoides plantation and Paramichelia baillonii plantation were 62 93 mm and 67 94 mm respectively. Some understandings were achieved on the water conservation functions and roles of Betula alnoides plantation and Paramichelia baillonii plantation.
