摘    要:季节雨林和橡胶林是西双版纳热带森林系统中可以代表原始林和大面积种植的人工林两种林型,采用水量平衡法,利用对以上两种林分林冠水文各分量1996~2001年的观测结果,初步分析其林冠水文效应,结果表明:一年内,季节雨林林冠截留量660.6mm,树干径流量80.7mm,穿透降雨量,853.2mm,分别占同期降雨总量的41.43%、5.24%、53.74%;橡胶林林冠截留量393.5mm,树干径流量104.1mm,穿透降雨量1096.8mm,分别占同期降雨总量的24.68%、6.68%、67.85%;两种林分森林水文各分量干、雨季差异显著,在研究中还发现,季节雨林中树干径流量随径级的增大而减小,干季出现密林(季节雨林)的穿透降雨量大于疏林(橡胶林)的反常现象;与我国其他地区相比,季节雨林和橡胶林有较大的林冠截留率及干流率。

关 键 词:热带季节雨林  橡胶林  降雨  林冠截留  水文效应  树干径流  西双版纳  热带森林系统  林分

Abstract:The Region of Xishuangbanna is located in the north edge of the distribution of tropical rainforest in the world, and it has remarkable seasonal climate variations which is different from tropical rainforest in other regions. In Xishuangbanna, the canopy of rubber forest (Hevea brasiliensis) plantation often form a single layer structure that is different from the multiplayer canopy found in natural tropical seasonal rainforest. The objective of this research is to compare and quantify the hydrological char...
Keywords:tropical seasonal rainforest  rubber forest  rainfall  canopy interception  stemflow  throughfall  Xishuangbanna
