摘要
本文介绍了南岳的自然条件以及森林土壤的基本特点如酸碱度、土壤含水量、比重、浸水容重、质地、有机质、有效氮、速效磷、速效钾等情况。作者首次应用定量方法即回归分析研究了土壤紧实度与土壤层次、结构及其有机质含量的关系,还讨论了土壤侵蚀和人畜践踏对土壤紧实度的影响。
This paper introduces the natural conditions, pH-value, moisture content,specific gravity, unit weight, texture, organic matter, capacity of effective N, available P2O5 and available K2O of the forest soils in Nanyue. The author studies the relationshiphs among the layer, structure,organic matter and compactness of soil in Nanyue by using the quantitative method i. e. regressive analysis;Besides,it discusses that soil erosion and trample of the person and domestics etc. have the influence upon soil compactness.
