摘　　要：对怀化市马尾松林地土壤调查取样,分析土壤理化性状及养分含量分布格局。结果表明:人工马尾松林地对氮素积累效应明显,全磷全钾含量低于荒山对照,有机质含量有明显提高,pH值有所下降,土壤有酸化的趋势;怀化地区马尾松林地多分布在低氮低磷区,磷素缺乏,林区土壤全钾和有机质分布较均匀。The soil from Pinus massoniana forestland in Huaihua city was sampled to analyze physiochemical characteristics and nutrient content distribution pattern. The results show that the nitrogen accumulation effect in artificial Pinus massoniana forestland was obvious; the contents of total P and total K were lower than that in control （barren hills）, the content of organic matter had been significantly improved, but the pH value decreased, and the trend of soil acidification existed; Pinus massoniana forestland in Huaihua city mainly distribute in areas with low nitrogen and low phosphorus, where lack phosphorus, but total potassium and organic matter are uniformly distributed.
