南岳林地的水文——物理特性及涵养水源能力研究

The hydrologic physical character and conserve water abillity of forest in Nanyue District

对南岳不同类型的林地的水文———物理特性 ,即土壤团聚体含量、水稳性指数、土壤入渗特性、土壤贮水特性的测定来反映不同类型林地土壤的抗冲抗蚀能力、土壤渗透能力及涵养水源能力 ,从而揭示不同植被———土壤系统对生态环境因子———水的影响。

Based on the determination hydrologic physical character in different type forest in Nanyue district.The determination including aggregated content of soil,index of water stability,water storage character of soil.Through them to reflect the antilash and antierosion ability soil penetrability and conserve water ability in different type of forest soil.The effect of the ecological environment factor, water in the different vegetative cover-soil system were announced in the paper.
