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。
Through the determination of three kinds of typical vegetation and its soil in Daqingshan, Inner Mongolia, the water conservation function of different forest vegetation was studied. The results showed that the maximum canopy interception of Pinus tabulaeformis forest was 0.170mm, the larch and Betula platyphylla forest were 0.104mm and 0.052mm, the water holding capacity of larch forest was significantly higher than that of Betula platyphylla forest and Pinus tabulaeformis forest, Larix gmelinii forest and Pinus tabulaeformis forest were better than those of Larix principis-rupprechtii forest and Pinus tabulaeformis forest. After comprehensive evaluation, Larix gmelinii forest had the strongest water conservation ability.
