| 摘要: |
| 为全面了解广西廉州湾红树林群落本底数据，预测其发展方向，本研究以广西廉州湾红树林群落为研究对象，在东江口、木案、针鱼墩、垌尾设置4条典型断面共计36个样方，调查红树林群落的类型、树高、覆盖度、冠幅、基径等，并计算物种重要值、多样性指数等指标，分析种群动态及分布格局。结果表明，广西廉州湾红树林树种以演替前中期树种为主，群落结构简单；物种重要值的排序为桐花树（Aegiceras corniculatum）>秋茄（Kandelia obovata）>白骨壤（Avicennia marina）>老鼠簕（Acanthus ilicifolius），大多种群主要呈集群分布；更新层以桐花树和秋茄幼苗为主，与该地现有成年红树植物物种重要值排序一致。广西廉州湾红树林群落是由陆向海逐渐发育的，未来该地红树林群落物种组成发生变化的可能性不大。如果人为干扰得以控制，红树林面积有望继续增加。 |

| Abstract: |
| In order to fully understand the background data of mangrove community in Lianzhou Bay,Guangxi and predict its future development direction,the mangrove community in Lianzhou Bay of Guangxi was taken as the research object.A total of 36 samples in 4 typical sections were set up in Dongjiangkou,Mu'an,Zhenyudun and Dongwei.The mangrove species,plant height,coverage,crown diameter and base diameter of mangrove community were investigated.The important values and diversity of species were calculated,and the population dynamics and distribution pattern were analyzed.The results showed that the mangrove in Lianzhou Bay,Guangxi,were mainly species in the early and middle stages of succession,and the community structure was simple.The order of important value for each specie was Aegiceras corniculatum>Kandelia obovata>Avicennia marina>Acanthus ilicifolius,mainly distributed in clusters.The regeneration layer was dominated by A.corniculatum and K.obovata,which was consistent with the order of the important values of the existing adult mangrove plant species in the area.Mangroves in Lianzhou Bay,Guangxi are gradually developed from land to sea.It is unlikely that the species composition of mangrove community will change in the near future,but the area of mangrove is expected to continue to increase if human disturbance can be effectively controlled. |
