Chemical properties of different forest types of soil in mountain area of eastern Liaoning

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.
