中文摘要：利用Hegyi提出的单木竞争指数模型分析湛江市特呈岛红海兰混交群落种内和种间竞争指数。结果表明,红海兰种内种间竞争指数随着林木径级增大而减少;径级在3.0-3.9cm时受到的竞争强度最大;种内竞争远大于种间竞争;种间竞争强度的顺序为海榄雌〉木榄〉秋茄树;红海兰种内、种间和林分竞争强度服从幂函数关系。

外文摘要：Using intraspecific and interspecific competition of Rhizophora stylosa occurring in Techeng Isle of Zhanjiang were analyzed by using Hegyi＇s competition index model for individual tree. The results showed that intraspecific and interspecific competition index of R. stylosa reduced with the increase in diameter scale of the trees. The competitive intensity reached the maximum when the diameter class was between 3.0 cm and 3.9 cm. The intraspecific competition was much larger than interspecific competition. The order of interspecific competition was listed as ：Avicennia marina〉Bruguiera gymnorrhiza〉Kandelia candel. The intraspecific and interspecific, as well as forest stand competitive intensities of R. stylosa matched the power function CI=-AD^B .
