摘要
对不同杉木混交类型幼龄林林分的林冠层、林下植被和枯枝落叶层以及林地土壤贮水性能的研究分析表明：在各杉木混交模式中以杉木×米老排的林分涵养水源能力最强，地上部分总持水量和林地土壤贮水量都大，总持水量为2918．12t／hm2，具有较大的初渗值（24．20mm／min）和终渗值（10．49mm／min）。
This paper presented hydrologic characteristics of canopy, understory, litter and mineral soil indifferent kinds of young mixed forests of Chinese fir by measuring water-holding, Through anlysing andcomparing, the results showed that the mixed stands of Cunninghamia lanceolata with Mytilaria laosensis hadthe strongest function of water conservation, its total water-holding above groung and total water-holding inmineral soil all larger than others, and the original permeation value and end permeation value were also larger than others, reached to 24. 20rum/min and 10. 49mm/min respectively.
