摘要
以太原市西山油松人工林地为研究对象,对三个开采强度下油松林不同深度土壤物理属性和水分状况进行调查和分析测定,对比分析煤炭开采的影响。结果表明:随着煤炭开采强度的加大,土壤总孔隙度、毛管孔隙度、非毛管孔隙度下降,土壤上层和下层容重趋于一致,土壤饱和含水量下降。说明随着煤炭开采强度的加大,导致林地土壤结构变化,损害了林地土壤的保水性能。
The study put the soil in artificial forest land in Tai Yuan East Mountain as research material.In this study,locating the plots with three gradients coal mining,the soil physical properties and water content in different depths were investigated and analysed.The results showed that with the increased intensity of coal mining,total porosity,capillary porosity,non-capillary porosity in the soil decreased,the upper and lower soil bulk density tended to be identical,soil saturation moisture content decreased.The results suggested quantitatively that the increase of coal mining changed soil structure and damaged soil water retention.
