摘要
本文对不同人工林下黑土的水分状况、土壤结构、酸碱性、有机质含量及腐殖质组成进行了研究。结果表明，由于常绿针叶林春季强烈的蒸腾作用，使土壤明显干燥，而阔叶林下土壤则水分充足，针叶林特别是常绿针叶林土壤ＰＨ值有所下降，而阔叶林的土壤趋于中性；造林３０年后，表土有机质含量明显增加，其幅度阔叶林比针叶林大。
This paper concerns water situation,soil constitution,PH value,organic matter content and humic composition of chernozem under different artificial forest.The result showsthe soil under conifer forest is dry due to strong transpiration in spring,and soil water isabundant under deciduous forest;PH value of soil reduces under conifer forest,particularlyevergreen conifer forest and PH value tends to neuter under deciduous forest;After 30 yearsold of reforestation,the organic matter content of surface soil increases,obsviously and larger range of deciduous forest than conifer forest.
