辽西山地典型森林土壤物理性质分析

Analysis of Soil Physical Properties of Typical Forest in Western Liaoning Mountainous Area

文章以辽西地区分布最广的油松、山杏林下土壤为研究对象,以土壤物理性质为主线,通过设置样地、采样、指标测定等方法,分析了土壤物理性质,揭示油松、山杏、油松—山杏混交林3种人工林林下土壤物理性质的区别。分析结果表明,在密度适宜的情况下,建立针阔混交林,例如,油松+山杏混交林,能进一步提高林地土壤的物理状况。

This paper takes the soil under Pinus tabulaeformis and Apricot forests,which are the most widely distributed in western Liaoning,as the research object,and takes the soil physical properties as the main line.By setting sample plots,sampling and index determination,the soil physical properties are analyzed,and the differences of soil physical properties under three plantations,namely Pinus tabulaeformis,Apricot and Pinus tabulaeformis-Apricot mixed forest,are revealed.The analysis results showed that the establishment of coniferous and broad-leaved mixed forest,such as Pinus tabulaeformis+Prunus armeniaca mixed forest,could further improve the physical condition of forest land soil under the condition of appropriate density.
