摘　　要：[目的]为红树林的生态恢复提供参考。[方法]对海南东寨港国家级自然保护区不同离岸距离潮滩上生长的11年生海桑+无瓣海桑红树群落的物种多样性及林分结构进行调查研究。[结果]用海桑和无瓣海桑造林能有效地在天然红树林外缘促进以秋茄、桐花、白骨壤为主的乡土红树植物的生长;在不同离岸距离潮滩上生长的海桑+无瓣海桑人工林的林分结构有较大差异,近岸边区域,林内非先锋乡土树种的发育程度要比远离岸边的区域高,初步推断这可能与风浪大小有关。[结论]在进行红树林人工造林时,应充分考虑当地海滩的风浪情况;可考虑以天然林的林缘潮位作基准以确定滩涂的相对潮位,以反映不同红树林生长区内红树植物适生的周期性淹浸深度。[ Objective] The reference for the ecological recovery of Mangroves was provided through the research. [ Method ] The diversity and composition of species in the mangrove community grown for 11 years at the different distances away from the offshore tidal flat in State Hainan Dongzhai Harbour Natural Protection Zone were investigated and studied. [ Results] The growth of indigenous mangrove such as Kano delia Candel, Aegiceras aorniculatum and Avicennia outside marina of the artificial forest system of S. carseolaris and Sonneratia apetala could be promoted. There was great difference in the structure of S. carseolaris ＋ Sonneratia apetala with the variable distances away from offshore tidal flat. It was in general showed that the development of non-pioneer native forest in nearly shore was higher than in the far from shore, which, could be related with the windy degree. [ Conclusion ] The windy wave in sea-beach should be appropriately considered in the construetion of the artificial forest of S. carseolaris ＋ Sonneratia apetala mangrove forest. The tidal flatting location reflected by the natural forest can be referred for the research on the tidal flat on the mangrove growth in the ecological system.
