| 摘 要： | 在大庆地区苏打盐渍土典型地段设置样方90个,对样方内地表植被种类、覆盖度及植被生长状况进行了调查,在土壤剖面0～20cm范围内取样,测定土壤pH值、水溶性总盐量及有机质含量。据此对大庆苏打盐渍土壤的碱度、盐化程度及养分等级进行划分,采用聚类分析方法对大庆苏打盐渍土进行分类和评价,探讨了苏打盐渍土的盐肥关系。

| Abstract: | Ninety sample plots were set up at the typical areas of soda saline soil in Daqing. Vegetation species, coverage and growth conditions of vegetations were investigated and recorded in every sample plot, and soil samples were taken to determine pH, total content of water-soluble salt and soil organic matter content. With the method of cluster analysis, the soda-saline soil was classified and evaluated by alkalinity, electropositive degree and nutrient level based on the obtained data. The relationships between soil pH, total content of water-soluble salt and soil organic matter content were analysed. |
