江西庐山自然保护区不同森林植被下土壤理化性状研究

以庐山自然保护区内6种主要森林植被下土壤为研究对象，对其进行植被因子调查及其土壤理化性状分析比较。结果表明：不同森林植被下平均土壤硬度的变化范围是13．24±8．63-25．43±7．72kg·cm^-2；马尾松林下土壤硬度平均值最小，土壤毛管孔隙度、饱和持水量、田间持水量的平均值最大，而黄山松林下土壤容重值最大；在林地土壤养分方面，阔叶林下土壤有机质、全氮、碱解氮等养分含量相对较高，而土壤含磷、钾量相对偏少。

Analysis of the Physi-Chemical Characters of Soil in Lushan Natural Reserve of Jiangxi

Based on six representative types of forest vegetation in Lushan Natural Reserve, the vegetation factors are investigated and the physi-chemical characters of soil are analyzed and compared. The results show that the average soil hardness under different vegetation ranges from 13.24±8.63 to 25.43±7.72 kg.cm^-2. The average soil hardness under the Pinus massoniana forest is the least, while its average gross soil porosity, saturation moisture capacity, field moisture capacity are the largest. The soil bulk density under Pinus Taiwanensis Hayata is the largest. As to the soil nutrient under the Conifer forest, the content of organic matter, total N and alkali-hydrolyzable nitrogen are comparatively high, while the content of P and K are relatively low.
