人工油松林火烧前后土壤化学性质变化的研究

Study on the Changes in Some Chemical Soil ProFerties After Burning

本文对人工油松林火烧前后土壤化学性质变化进行了研究。研究结果表明，火烧后土壤ｐＨ值、土壤盐基饱和度、土壤交换性阳离子和土壤阳离子交换量等土壤化学性质均受到不同程度影响。其中，以土壤表层变化最强烈。

Having studied the changes in some chemical soil properties after burning,the following results are obtained;the chemical soil properties,for example,base saturation, pH value,exchangeable cation and exchange capacity ect, all of changes in varying degrees,especially the properties of soil epipedon.
