漳江口红树林国家级自然保护区无瓣海桑的扩散现状研究

摘要

Based on the field survey,the diffusion of Sonneratiaapetala in Zhangjiangkou Mangrove National Nature Reserve was analyzed.Results showed that (1)Sonneratiaapetala is in the early stages of diffusion,the number of individual increase by year;(2)they concentrated distribution in the mixing zone of fresh and salty water in middle reaches;(3)Sonneratia apetala exited niche overlap with native mangroves;(4)Sonneratia apetala seedlings are mainly from natural diffusion.%通过对漳江口红树林自然保护区无瓣海桑分布现状进行研究，结果表明：(1)漳江口红树林国家级自然保护区内的无瓣海桑尚处于扩散的早期阶段，个体数量呈逐年增长趋势；(2)中游咸淡水交汇区是无瓣海桑分布较集中的区域，且多沿潮沟生长分布；(3)无瓣海桑和乡土红树植物的生态位重叠；(4)保护区内无瓣海桑幼苗主要来源于自然扩散。
