| 摘 要： | 为了研究橡胶林生态系统中降雨在林冠层、土壤层等不同界面层的水分转换机制及各项水因子量之间的关系，利用野外观测试验站，针对橡胶林水分循环动态变化过程中各项相关因子进行持续1年的观测。结果表明：穿透雨量、树干茎流量、林冠截留量分别占年降水量的71.63%、11.54%、16.30%；净降水中以地表径流、渗漏形式损耗的水分分别占年降雨量的4.71%、26.23%；橡胶林林冠和土壤以蒸散形式返回大气系统的水分分别占总降雨量的52.65%、16.30%。分析比较橡胶林水分循环过程中各水因子量的分配特征，从理论基础和量化指标的角度上阐明了橡胶林生态建设的水文效应评价问题。

| Abstract: | To research the transforming mechanism of the rainfall in the canopy and soil layer,and the relationship between each water factors,the author investigated the factors for a year.The results showed that throughfall,stemflow and canopy interception made up of 71.63%,11.54%,16.30% of the rainfall,respectively,and stemflow,infiltration out of net rainfall accounted for 4.71%,26.23% respectively,and evapotranspiration from canopy and soil accounted 52.65%,16.30% for the rainfall respectively.Besides,the author analyzed the distribution characterization of water factors associated with hydrology,and indicated the effect in the hydrologic assessment in the ecological construction of the rubber forest from the aspects of theory and quantized index. |
