摘　　要：研究土壤中植物生长必需营养元素含量,对植物正常生长发育具有十分重要的意义。以辽南丘陵区熊岳、山前冲积平原区牧城驿两个地区的棕壤剖面为研究对象,采用野外土样采集和室内实验测试分析相结合的研究方法,对每一剖面不同发生层营养元素的分异特征进行测试研究。结果表明:辽南棕壤剖面不同发生层中大量营养元素,虽然各有差异,但均具有不同程度的变异性。Researches on plant growth essential nutrition elements contents in soil is of great significance for studying the nor- mal growth and development of plant. With the two objections, South Liaoning hilly zone XiongYue and plain alluvial MuChengyi two regions of the soil profile＇ as research objects, the research adopts the method of field soil sampling and laboratory test analysis to discuss each section of different characteristics of layer of nutrient elements. The results show that：The average content of large nu- trient elements in southern Liaoning soil profiles of different layers of all nutrient elements have different degrees of variability.
