为了解马尾松林土壤异质性规律，分别在4个地点于4个季节进行取样，分析土壤 pH、速效氮、速效磷和速效钾等4个指标的变化。结果表明：不同地点的 pH、速效氮、速效磷和速效钾均存在差异，并达到显著差异水平（p＝0），而不同季节的变化也不同，除 pH 未达到显著性差异外（p ＝0．571），有机质、速效氮、速效磷和速效钾的含量均达到显著差异水平（p ＝0），研究区域的马尾松林分土壤不仅存在空间异质性，同时也存在时间异质性。

To explore the nutrient heterogeneity law of P .massoniana forests soil,variation of soil pH,available N,available P and available K was studied in Spring,Summer,Fall and Winter in four forests.Results:pH,available N,available P and available K varied in different forests(p=0),which were different in different seasons either,the four indicators but pH(p =0.571)were of significant difference (p=0).These showed that there not only had space nutrient heterogeneity,but also had time nutrient heterogeneity in P .massoniana forests soil in study area.
