摘要: 收集了海南岛49个植物采样点约300个样品,用光谱法和化学法测定了植物中大量元素(N、P、K、Ca、Mg)和微量元素(Zn、Cu、Mo、Pb、Cr、Ni、Cd、Fe、As、Hg)的含量。在应用数理统计处理数据的基础上,对海南岛86种植物的化学成分特点及各元素间的相关关系进行了分析和讨论,初步建立海南岛植物元素间的相关方程式,从而可了解元素间含量变化的特征。

Abstract: In observance of the requirement for specimens sampling, about 300 samples from 49 sampling stations of plant communities in Hainan Island were colected. The contents of macronutrients (N, P, K, Ca, Mg) and trace elements (Fe, Zn, Cu, Mo, Pb, Cr, Ni, Cd, As, Hg,) were determined by spectrophotometric and chemical methods.By statistical processing of the obtained data, both the characteristics of chemical composition and the interrelationship between the elements in 86 plant species were studied. With the help of an electronic computer, some correlation equations were established between the elements in the plants. As a result there is a possibility for forecasting the changes among the elements in plants in this island.
