摘　　要：以塔里木盆地特有种硬枝碱蓬为研究对象，调查了35个硬枝碱蓬群落的层盖度、层高度、总盖度及伴生植物，同时分析、测定了35个群落的土壤总盐、pH、水解氮、速效P和速效K，并对数据进行多元统计分析。结果表明：硬枝碱蓬在含盐0．39～13％的土壤上可以正常生长，土壤盐分对其层盖度、层高度、总盖度影响不显著，水解氮和速效钾对硬枝碱蓬影响达0．05显著水平，pH和速效磷对硬枝碱蓬影响达0．01极显著水平，说明pH和速效磷是影响硬枝碱蓬生长及层盖度、层高度、总盖度的主要因素.Based on the object of Suaeda linifolia Pall grows in Trim basin, the layer overlay degree, height, total overlay degree, associated plant of 35 communities were investigated, soil total salt content, pH, available N, available P, available K were also determined ; Through multianalysis, the result showed that Suaeda linifoliaPall could natural grow in the soil with the salt content of 0. 39 13% so, soil salt effect was unapparent for layer overlay degree, height, total overlay degree; available N, available K were 0. 05 prominence level, available P, pH were 0.01 prominence level for Suaeda linifoliaPall growth. That indicated that available P and pH were the main factors which affected Suaeda linifoliaPall growth, layer overlay degree, height, total overlay degree.
