摘要
对辽宁清原森林的三种森林类型(红松林、落叶松林、次生林)不同层次(0～10cm,10～20cm)土壤的化学性质进行了测定对比分析,结果表明:同种林型,不同层次的土壤养分存在着明显的差异;pH值和土壤养分也因林型不同而呈现不同的变化趋势。土壤有机质与氮、磷、钾等养分含量相对较高。从而在化学性质方面有力地揭示了清原森林不同森林类型的土壤特征。
The chemical properties of soil under three types of forests in Qingyuan forest including Korean pine forest, larch and secondary forest are analyzed. The results show that for the same forest type, the nutrients in the soil at different levels （ 0～ 10cm and 10～20cm ）are different and soil nutrient and pH value are varied with different forest type. As for the soil nutrient, the soil organic matter and the content of N, P and Kof the soil are comparatively high under the Qingyuan forest .Thus the characteristics of different forest types of soil inQingyuan forest are revealed in the chemical property aspect.
