中文摘要：以广东湛江港航道的红树林典型样方的群落为研究对象,开展船舶兴波对红树林空间结构的影响研究。应用混交度、大小比数、角尺度和竞争指数等空间结构指标,构建了红树林航道防护功能指数,同时运用该指数分析了湛江港特呈岛不同林分的防护功能状况。结果表明:A样带的白骨壤林分航道防护功能指数为0.32,为Ⅳ级较低防护水平;B样带白骨壤+红海榄+木榄混交林航道防护功能指数为0.67,为Ⅱ级较高防护水平。因此,特呈岛白骨壤林分防护指数低,混交林林分防护指数高。

外文摘要：By takin g the community in mangroves typical plots along the laterals of Zhanjiang, Guangdong harbor channel as the research object, the effects of ship wave-making on mangrove forest spatial structure were studied. With the spatial structure indexes etc.（ mingling,neighborhood comparison,neighborhood pattern and competition index）, the man grove waterways protection index model was put forward. At the same time, by using the obtained index model, the protective function status of different forest stands along Techeng Island, Zhanjiang Port was analyzed. The results show that the waterway protection function index of Acacia marina in A-sample zone was 0.32, being Ⅳ level（low protection level）; that of A. marina＋Rhizophora ＋ Bruguiera gymnorrhiza mixed forest in B-sample zone was 0. 67, being Ⅱ level（high protection level）. Therefore, the index of A. marina in A-sample zone was low, while that of the mixed forest was high.
