摘要: 通过对内蒙古大青山3种典型植被及其土壤的测定,研究比较了不同森林植被的水源涵养功能。结果表明:油松林的林冠截留量最大,为0.170mm,落叶松林和白桦林依次为0.104mm和0.052mm;落叶松林枯落物持水能力显著高于白桦林和油松林,白桦林土壤贮水能力大于落叶松林和油松林;经综合评价,落叶松林水源涵养能力最强,油松林其次,白桦林水源涵养能力最差。

Abstract: Based on the measurement of forest and soil of 3 typical types of vegetation of Daqing Mountain in Inner Mongolia, water conservation functions of different forest vegetation were studied and compared. The results showed that the canopy interception of Pinus tabulaeformis is 0.170mm, that of Larix principis-rup prechtii and Betula platyphylla 0.104mm and 0.052mm. Water-holding capacity of Larix principis-rup prechtii's litters is significantly higher than Betula platyphylla's and Pinus tabulaeformis's, water-retaining capacity of Betula platyphylla's soil is greater than Larix principis-rup prechtii's and Pinus tabulaeformis's. Through comprehensive evaluation, water conservation function of Larix principis-rup prechtii is the strongest, then Pinus tabulaeformis and Betula platyphylla is weakest.
