摘　　要： 采用区域调查和定位试验研究方法,以梅江区为研究区域,系统研究了不同森林类型土壤理化性质及其对水源涵养功能的影响。结果表明,在相同立地条件下,天然常绿阔叶林比马尾松林具有更显著的改善土壤理化性质的能力。天然常绿阔叶林总贮水量高达每公顷2749.8t,分别比人工桉树林、灌木林、马尾松林增加6.1%、8.9%和12.7%。依据林地总贮水量的大小,4种林分的水源涵养功能依次为天然常绿阔叶林>人工桉树林>灌木林>马尾松林。 The soil physical and chemical properties and the water-conservation function of different forest have been researched on the base of the methods of typical region investigation,experiment study in site in the fixed standard area in Meijiang. The result showed that there existed significant differences in soil properties and water conservation function among forest types. Under the similar site condition, the broad-leaf forest had greater water conservation function and better maintenance of soil fertility than the Coniferous forest did. The total water-holding capacity of broad-leaf forest is 2 749.8 t·hm^-2, higher than eucalyptus forest, shrub forest and Coniferous forest respectively by 6.1%,8.9% and 12.7%. Based on the total water-holding capacity of litter and soil （0-60 cm）, the orders of the water conservation function for the four forest types was： broad-leaf forest〉eucalyptus forest〉shrub forest〉Coniferous forest.
