摘要
应用土壤物理学的方法、理论和参数,对研究地区现有的水土保持林的林地土壤水分物理性质进行了实地观测和分析,实验采用了玛立奥特瓶定水头供水的渗透仪法和野外实地土壤水分再分布法,其结果为该地区水土保持和森林水文效益评价研究提供了可靠的依据。
By means of the method of soil physics this paper is to determine the physical char-acteristics of soilmoistiire in shdter forests.Thestudy isbased on themeasurement of saturatedhydraulic conductivity with a constant-head parameter and in-site measuring of soil water redis-tribution. The result of this study is useful for the research and appraising of the effect of soil andwater conservationand forestry hydrology at local regions.
