以广西竹山红树林群落为研究对象,调查了红树林群落类型、密度、高度、覆盖度、更新层等,研究表明广西竹山红树林群落从内滩到外滩的演替规律为:桐花树、桐花树+白骨壤群丛→桐花+白骨壤-秋茄+海漆-桐花树+老鼠勒+卤蕨、白骨壤+桐花树→桐花树、桐花+白骨壤。种群分布格局为:桐花树呈集群分布,白骨壤、秋茄、海漆、老鼠簕呈随机分布。该群落人为干扰较多,在较小面积的滩面内集中了相对较多的群落类型,以桐花树群丛和桐花树+白骨壤两种群落为主,呈低矮的单层灌木状。样方中各个滩位均有更新层,且更新层的高度差异显著,表明该地区的红树林群落处于发展的初期。
Taking the mangrove community of Zhushan in Guangxi as the research object, the type, density, height, coverage and renewal layer of mangrove community were investigated. The succession rule of Mangrove community in Inner Mongolia from inland to the Bund was: Aegicerasian tree + Avicennia group → Aegiceras corniculata - Avicennia marina + Aegiceras corniculatus - Aegiceras corniculatus + Lemna exolera, Avicennia marina + Aegiceras corniculatus → Aegiceras corniculatus, Aegiceras corniculatum + Avicennia marina. Population distribution pattern: Aegiceras corniculatus was cluster distribution, Avicennia marina, candelia, sea lacquer, mice were randomly distributed. There were more man-made disturbances in this community, and relatively more community types were concentrated in the smaller area of the beach surface. The communities were mainly of the two shrubs, Aegiceras corniculatum and Aegiceras corniculatum, with low shrubs. There is an updated layer at each beach level in the quadrat and the height of the updated layer is significantly different, indicating that the mangrove community in the area is in the early stage of development.
