摘　　要：基于对松嫩盐碱草地植物种群分布特点及影响植物种群分布格局的生态环境因素的分析，提出了盐碱草地植物种群分布与土壤营养关系的一种分析方法──土壤营养位分析。给出了土壤营养位的计测方法，并讨论了土壤营养位效能指标的选择和土壤营养轴上测定指标的处理。Based on the distribution of plant population on Songnen alkaline grassland and ecofogica environmental characters affecting the pattern of plant population distribution, this paper proposes an approach to analyzing the relationship between plant population and soil nutrition on alkaline grassland, which is called as soil nutrient field analysis. The methods measuring and calculating soil nutrient field has put forward,selection of the parameter of soil nutrient field efficiency as well as disposal methods of soil data on soil nutriment axis is discussed in this paper， too．
