摘　　要：文章以海南省儋州市南部植胶区各农场橡胶人工林地为研究对象,运用典型相关分析研究了橡胶人工林地土壤酶活性和土壤微量元素含量关系。结果表明,土壤有效锰与土壤过氧化氢酶活性的关系最大;土壤有效锌、有效铜与土壤脲酶、多酚氧化酶活性关系密切。各橡胶人工林样点,在典型变量排序图上以不同成土母岩聚集。In farm rubber plantations of the west of Danzhou, Hainan province, canonical correlation analy-sis was applied to the research of relation between soil enzyme activities and soil available microelement. The resuits showed that among the test elements, only available Mn, Zn and Cu affected enzyme activity. The available Mn had great relation with the activity of soil peroxidase, both available Zn and Cu were closely related with the activities of soil urease and polyphenol oxidase. The samples of rubber plantations were conglomeration by different soil mother rock in graph of canonical variables ordination.
