| 摘 要： | 分析了海南80种植物（青梅，坡垒，黄杞，荷木，海南蒲桃，琼南柿，油丹，琼楠，陆均松，海南油杉，橡胶，木麻黄等）叶片15个元素的含量，探讨这些元素在不同植物生活型的变化及元素间的相互关系。结果表明：植物叶片的元素含量在种间和元素间的变化范围都较大，植被类型和植物生活型对叶片元素含量有显著影响。海南大多数植被的N/P比率较小，属于N含量制约的植被类型。元素比值和元素相关分析结果说明植物体内必需的营养元素具有一定的比例组成和协调关系。

| Abstract: | This paper dealt with variation of chemical elements and relationship between the elements in various vegetation types and plant life forms of Hainan Province,based on the analysis of 15 elements in plant leaves of 80 species.The results showed that:there were big ranges of element concentrations in plant leaves among the species or elements.The vegetation types and plant life forms had the obvious effects on element concentrations in plant leaves.N/P ratios were small for most vegetation types of Hainan Province.This indicated that N concentration was a major limited factor for plant growth.It was pointed out by the analysis of element ratios and correlation coefficients that plants had relatively constant composition and coordinated relationship for necessary nutrient elements. |
