| 摘 要： | 对青藏高原东缘贡嘎山东坡森林土壤有效微量元素的含量、分布及影响因子进行了研究。结果表明,四种典型土壤土层中有机质、水解氮、有效磷和速效钾的含量基本表现为由上而下逐渐降低的趋势;且在不同林型条件下,土壤养分含量分布也有差异;位于不同海拔高度的土层中,有机质等常量养分的分布表现出两头高、中间低的态势。土壤中B、Zn、Mn三种元素的含量均低于或远远低于各自的临界值;除Mn以外,有效态微量元素B、Cu、Zn、Fe含量均呈现出自上而下逐渐减少的趋势,即为表层富集型。

| Abstract: | According to data from forest soil of east slope,Gongga mountain,Qinghai-Tibet Platean,the content,the distribution and effecting factors of elements in soil were analyzed.The results show that in four soils,the content distributions of macro nutrients such as organic matter represent a trend decreasing top to bottom,it also varies with different forests.Furthermore,the content of macro nutrients is higher than that in higher and lower altitudes but it is lower in the middle altitude.The content of B,Cu,Zn,Fe is much lower than their critical values.Except for Mn,the content of B,Cu,Zn,Fe was decreased from top to bottom. |
