摘要
镇江北固山湿地属于长江近河口段淡水潮汐湿地,植物群落基本保持原生演替的前期状况。根据对该湿地的实地观测研究,描述了河滨湿地植物的生长特性;结合湿地的水文特征刻画了湿地高等水生植物在时间、空间和景观上的生态过程;综合河滨湿地植物的生长特性及湿地的水文特征探讨了镇江淡水潮汐湿地的演变趋势。对湿地面临的问题进行了讨论,从而为长江淡水潮汐湿地的生态修复和增加生物多样性及湿地保护提供参考。
Beigushan wetland is a newly formed tidal freshwater wetland which is not far to the Changjiang Estuary. The plant community in the wetland was in its prophase status of the primary successions. According to the survey on the Beigushan wetland, growing characteristics of the wetland plants were described. In combination with hydrological characters, the paper discussed the evolution rule for the dominance in this community in relation to the temporal, spatial and landscape changes and also to the trend of the wetland evolution. The problems existed in the wetland communities were also discussed, the conclusions may provide important information for the ecological restoration, and the protection of biodiversity and then wetland.
