| 摘 要： | 本文以我国云南典型热带森林生态系统为研究对象,在物质循环较封闭的地段,按照不同地貌部位、不同的物质淋溶堆积景观类型进行采样,采样时在同一单元景观内同时收集土壤、风化壳、植物和天然水的样品,分析各样品中九种重金属元素的含量分布以及土壤风化壳样品中各元素的六种赋存形态的含量分布,通过对比元素在不同单元景观间、不同景观要素间和景观要素内部的分异特征,从而给出热带森林生态系统中元素的分布形成规律和动态分异特征。

| Abstract: | According to the principles and methods cf landscape geochemistry, the samples of soil, plant and surface water collected at the same time eluvial, super-aqual and aqual landscapes in the different landforms were studied and analysed as a whole ecosystem.The abundance of the eight trace elements in every landscape's component and the geochemical patterns of the landscape were given, and the relationship between the couse of the characteristics and ; the environmental factors was disscussed by analyzing the ... |
