| 摘 要： | 讨论了西藏高原３６种元素的植物含量水平及其在土壤－植物系统的分而特征、影响因素、利用吸收系数和统计分析的方法，定量描述了植物对土壤不同元素的吸收、富集能力，研究结果表明，在西藏高原的土壤－植物系统中，亲硫元素和碱金属、碱土金属元素的生物地球化学行为较亲铁元素活跃，植物元素的类型划分和元素的地球化学行为密切相关。

| Abstract: | Contents of 36 element and their distribution in the soil-plant system on Xizang plateau as well as the factors influencing the distribution are discussed.Uptake and concentration of the elements in the soil by plant were analyzed statistically.The resutls of cluster analysis show that there is a close relationship between the classification of elements in plants and the element geochemical behavior.It is also demonstrated that the biogeochemical behavior of chalcophile elements, alkali and alkaline-earth metals are more active than those of siderophile elements in soil-plant system on the studied area. |
