[ Objective] The aim was to study the growth and environment factors of three native tree species ( Thespesia lampas, Calophyllum inophyllum and Hernandia sonora) in Hainan in coastal Casuarina equisetifolia plantation. [ Method ] The coastal sandy soil was treated by adding wood chips, bagasse and the control without adding anything in the plant pits. The growth of three native tree species planted for one year was analyzed. [ Result ] ① One year later, the survival rate showed an order of T. lampas ＞ H. sonora ＞ C. inophyllum;the net increase of basal diameter showed an order of H. sonora ＞ T. lampas ＞ C. inophyllum;while the net increase of plant height showed an order of T. lampas ＞ C.inophyllum ＞ H. sonora. The difference of survival rate between T. lampas and C. inophyllum was extremely significant, the difference of survival rate between H. sonora and C. inophyllum was significant, but the survival rate between T. lampas and H. sonora showed no significant difference. The difference on net growth of plant height among T. lampas, C. inophyllum and H. sonora was extremely significant, and the different on the net growth of basal diameter between T. lampas and C. inophyllum was significant. ② Among different soil treatments,the survival rate of three native tree species in the treatment by adding wood chips, bagasse were higher than the treatment without adding anything, and the difference of survival rate of T. lampas between the treatment by adding wood chips, bagasse and the treatment without adding anything was extremely significant, but the treatment by adding wood chips and bagasse had not significant difference. ③ The growth of three native tree species showed some correlation with environment factors ( | r |＞0.3). The survival rate of T. lampas showed higher correlation with soil pH value and soil moisture, and the basal diameter and height of T. lampas showed some correlation with soil pH value and soil temperature. The survival rate of C. inophyllum showed higher correlation with soil pH value, soil temperature and light intensity, while the basal diameter and height of C. inophyllum showed some correlation with soil temperature. The survival rate of H. sonora showed higher correlation with soil salinity and soil temperature, while the basal diameter and height of H. sonora showed some correlation with soil temperature. The basal diameter and height of three native tree species had higher correlation (r＞0.5), which had reached a significant level. [ Conclusion] In the one-year growth period in C. equisetifolia forest, the native tree species of T. lampas grew best and it was the most potential forest species mixed with C. equisetifolia.
