| 摘 要： | 本文对研究区的油松人工林和天然白桦次生林不同林龄的林冠截留量、枯落物持水量及土壤层的持水量进行了观测,并通过SAS数据处理软件对观测数据进行了分析。建立了自然降雨与林冠截留的回归方程,不同分解程度枯落物持水比率及持水速率的表达式,并对不同林分类型土壤持水量进行多重比较分析,结果显示油松人工林和天然白桦次生林的幼龄林、中龄林、成熟林土壤持水量依次增大并随着土层深度的增大持水能力呈下降趋势,天然白桦次生林的土壤持水量高于人工油松林。

| Abstract: | In this paper,the canopy interception,water holding capacity of litter and soil moisture level was observed in natural pine forest and the different ages of secondary birch,and the observation data were analyzed by SAS data processing software.The regression equation of natural rainfall and canopy interception was established.The result shows that soil water holding capacity is increasing from the Pinus tabulaeformis plantation and young-aged forest、middle-aged forest、matured forest of Betula platyphylla natural secondary forest,but there is a downward trend as soil depth increased.Soil water holding capacity of Betula platyphylla natural secondary forest is higher than that of Pinus tabulaeformis plantation. |
