摘　　要：为后期平衡施肥、改善土壤质量提供有针对性的参考,以吕梁山南部高天山地区分布的典型林分土壤为研究对象,通过测定土壤主要化学性质,对其养分状况进行分析,并对土壤养分含量进行分级。结果显示:该区域内土壤呈弱碱性或碱性;有机质含量较高,能够满足植物生长所需;整体缺乏磷肥,油松林地普遍缺乏氮肥,部分林地缺乏速效钾。To provide a targeted reference for balanced fertilization and improvement of soil quality in the later stage,taking the typical forest stand soil distributed in the Gaotian Mountain area in the southern of Lyuliang Mountain as the research object,by determining the main chemical properties of the soil,its nutrient status were analyzed,and the soil nutrients were analyzed.The content was classified.Result shows that the soil in this area is weakly alkaline or alkaline;the organic matter content is high,which can meet the needs of plant growth;the overall lack of phosphate fertilizer,Pinus tabulaeformis forest land generally lacks nitrogen fertilizer,and some forest land lacks available potassium.
