Abstract: The growing properties and adaptability of Casuarina equisetifolia, Pinus elliottii, and Acacia crassicarpa on coastal sandy sites were studied. The results showed that the growth of stand is closely related with the site types. The sandy soil deposited by wind is most suitable for the growth of 3 species. However, the hydrated soil deposited by wind and the uneven soil deposited by wind are not suitable for them. Their growing performances and adaptability were different. The growing speed was A. crassicarpa>C, equisetifolia>P, elliottii, the strong wind resistance was P. elliottii>C, equisetifolia>A, crassicarpa, and the moist sea wind resistance was C. equisetifolia>A, crassicarpa>P, elliottii. In general, C. equisetifolia still was the best tree species for constructing the coastal protection forest in the frontal costal sandy site. However, P. elliottii had the ability to resist the strong sea wind, and A. crassicarpa could adapt the dry sand site, grow fast in the coastal area, and improve the soil fertility. So, the different tree species could be selected to construct the coastal protection forest in different sites in order to get the best protection effect.
