中文摘要：应用传统踏查法对特呈岛主要红树林群落林窗边界木开展地径、冠幅、树高、枝下高、叶面积指数、偏冠率、健康指数等调查,分析特呈岛严重干扰下红树林林窗边界木特征。结果表明,特呈岛红树林将近一半林窗位于中潮带区,平均每个林窗拥有17.9株边界木,边界木以白骨壤和红海榄为主;边界木地径为0-20 cm,树高为3-6 m,呈正态分布;叶面积指数绝大分以Ⅰ级(0-5)为主;3级亚健康、4级不健康和5级垂死等健康指数的边界木株数接近一半;平均偏冠率仅为0.571 9。与健康林窗边界木对比,特呈岛严重干扰下红树林林窗边界木以低龄为主、株数多、健康指数及叶面积指数偏低,呈生长衰退现象。过于持续强烈的风浪干扰是主因。

外文摘要：By a survey of the ground diameter, crown, tree height, branches high, leaf area index, partial crown rate and health index, etc. The main border tree characters of serious disturbance mangrove forest gap in Techeng Island were investigated. The survey results showed that： nearly half of the gaps were in the middle tidal zone area, there were average 17.9 border trees in one gap, the main border trees were Avicennia marina and Rhizophora stylosa. The border tree ground diameter was mainly in 0 -20 cm, tree height was in 3 - 6 m, which appeared to be a normal distribution. The leaf area index substantially distributed in grade I （0 - 5 ） , the nmnbers of border trees of 11I inferior health class, IV ill health class, and V dying class, were close to the half, and the average partial crown rate was only 0. 571 9. Therefore, contrast to the health-wood forest gap, the severely disturbed mangrove forest gap border trees were mainly at younger age and the average number of trees was more than the heahh-wood forest gap. The health index and leaf area index were low, which showed a growth recession. Too continued strong storms interference was the main cause.
