摘　　要：对江西吉安不同类型退化湿地松群落土壤物理性质及养分状况进行了分析,结果表明:土壤孔隙度和自然含水量均为对照样地最小,孔隙度的顺序为:类型Ⅰ>补植木荷样>类型Ⅱ>补植胡枝子样>对照;自然含水量的顺序为:类型Ⅰ>类型Ⅱ>补植木荷样>补植胡枝子样>对照;土壤容重以对照样地和补植胡枝子样地较大,其余3种类型样地土壤容重相对较小。补植木荷和补植胡枝子样地土壤有机质、全氮、碱解氮含量比类型Ⅰ、类型Ⅱ样地低,但比对照样地高;土壤速效磷和速效钾含量在不同类型群落间差异没有规律性。Physical properties and nutrient contents of the degenerated soil of Pinus elliottii communities in Ji＇an of Jiangxi Province China, were measured. The results showed that the porosity ranked as type I Schirna superba 〉type Ⅱ 〉Lespedeza bicolor〉control, and natural water content： type I〉type Ⅱ 〉S. superba〉L, bicolorⅡ control. The stocking volumes in L. bicolor and control communities were larger and small in other three types. The soil organic matters in S. superba and L. bicolor forests were less than those in type I and typeⅡ forests, but more than those in control forest, so did the changing trend of soil total nitrogen and hydrolysable nitrogen. There was no regularity about soil available phosphorus and available potassium in different community types.
