天涝池流域祁连圆柏林地土壤持水特征研究
TV11%S152.7; 探究祁连圆柏林地的土壤持水能力,对研究高寒山区土壤水运动、溶质运移、林草植被生理用水等具有重要意义.本研究以祁连圆柏样地0～60 cm处的土壤为研究对象,利用离心分离法获取不同土层深度在指定转速下的土壤含水率,并选用Gardner、van Genuchten、Broods Corey、Fredlund Xing 4种经验模型对实测含水率和土壤基质势进行拟合,得到拟合土壤水分特征曲线.研究结果表明:①van Genuchten与Fredlund Xing模型的拟合精度最高且相差较小,因此两者均可作为祁连圆柏样地的最优拟合模型,但Fredlund Xing模型参数的物理意...

| Abstract | TV11%S152.7; 探究祁连圆柏林地的土壤持水能力,对研究高寒山区土壤水运动、溶质运移、林草植被生理用水等具有重要意义.本研究以祁连圆柏样地0～60 cm处的土壤为研究对象,利用离心分离法获取不同土层深度在指定转速下的土壤含水率,并选用Gardner、van Genuchten、Broods Corey、Fredlund Xing 4种经验模型对实测含水率和土壤基质势进行拟合,得到拟合土壤水分特征曲线.研究结果表明:①van Genuchten与Fredlund Xing模型的拟合精度最高且相差较小,因此两者均可作为祁连圆柏样地的最优拟合模型,但Fredlund Xing模型参数的物理意义更加明确.②祁连圆柏样地不同土层深度的土壤持水能力不同,且随土壤含水率的降低,这种差异性更加显著,其中40～50 cm土层在高吸力下(>0.1 MPa)仍能释放较多的水分,保持较高的含水率,持水能力相对较强;而0～10 cm土层释放水分少,含水率低,持水能力相对较弱;此外,30～60 cm土层的土壤持水性整体上要优于0～30 cm土层,因此30～60 cm土层是祁连圆柏样地的主要水源涵养层. |
