摘　　要：对海南省儋州市南部植胶区橡胶人工林土壤腐殖质组成与有效微量元素Cu、Fe、Zn、Mn含量进行了研究,结果表明:该植胶区橡胶林0～20cm土壤腐殖质组成是以富里酸为主,胡敏素次之,胡敏酸最小;土壤有效铁和有效锌含量较高,但有效铜和有效锰含量较低。典型相关分析表明,土壤腐殖酸、胡敏素均与有效铜关系密切且呈正相关。Soil humus composition and contents of available microelements （available Cu, Fe, Zn, Mn） were studied in rubber plantations in the west of Danzhou, Hainan Province. Results showed that soil humus composition was dominated by fulvic acid, followed by humin, and humic acid the lowest, and that soil available Fe and available Zn were rich in the rubber plantations while available Cu and available Mn poor. Canonical correlation analysis showed that the soil humic acid and humin were closely and positively correlated with available Cu.
