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.
