摘　　要：[目的]研究海南3种森林类型的土壤特性及水源涵养功能。[方法]以海南岛琼中地区天然次生林、马占相思林和15年生的橡胶林为研究对象,对不同森林类型的土壤理化特性和水源涵养功能进行了研究。[结果]不同森林的土壤理化特性及其持水量差异明显,天然次生林和马占相思林土壤容重小、孔隙多、有机质含量丰富、持水量大,而橡胶林土壤容重较大、孔隙少、有机质含量低、持水量低。3种森林类型0~40 cm土层的饱和持水量、毛管持水量从大到小依次为天然次生林、马占相思林、橡胶林。[结论]该研究可为海南岛森林生态系统可持续发展提供科学依据。[ Objective] To study the soil characteristics and water conservation function of forest types in Hainan Island. [ Method] The soil prop-erties and water conservation function of three different type forests （ Secondary forest, Acacia mangiurn forest and Hevea brasiliensis forest） in Hainan Island of Qiongzhong District were studied. [ Result ] The results showed that existed significant differences in soil properties and water conservation function among three types forest. The seconnary forest and Acac ie m a n g ium forest had small bulk density, more soil porosity, richorganic matter and large water-holding capacity in soil. But the Hevea brasiliensu forest had matter and low water-holding capacity in soil. The saturation moisture capacity and capillary moisture capacity in forest types from big to small were secondary forest, Acacia m a n g u r n forest, Hevea brasiliensu forest. [ Conclusion] entific basis for the sustainaie development of Hainan Island forest ecosystem.
