摘    要:对东帕米尔高原海拔3 000~4 100 m范围内的高寒土壤的有机质含量进行分析,揭示其随海拔高度变化的分布规律,并与土壤pH值及可溶盐含量进行相关性分析,探讨造成该区土壤有机质分布的原因.研究表明,该区土壤有机质含量丰富,平均值为20.943 g/kg,但不同采样点土壤有机质含量悬殊,标准差为8.370.随着海拔高度增加,有机质含量先增加后减小,在海拔3 600 m左右出现极小值.土壤有机质和可溶盐含量、土壤pH值均呈明显负相关关系,表明土壤含盐量和pH值对有机质积累有重要影响.

关 键 词:高寒土壤;有机质;相关分析;东帕米尔

Abstract:Alpine soil organic matter analysis which is from east Pamirs at an altitude of 3 000~4 100 m reveals the distribution law changing with altitude, soluble salt and soil pH. This study shows that the soil organic matter is rich, with the average of 20.943 g/kg, but different sampling points show a large disparity, with the standard deviation of 8.370. The organic matter increases between 3 000 m and 3 600 m, but decreases above 3 600 m. Soil organic matter shows obvious negative correlation to the soluble salt content and soil pH. Soil salinity and pH have important effects on the organic matter accumulation.
Keywords:alpine soil   organic matter   correlation analysis   east pamir
