摘　　要：海岸带生态环境是一个复杂的生态系统,由于生态系统结构和功能的多样性,生态修复需因地制宜,制定适合本土化的生态修复措施。分析广州市虎门大桥(北侧)海岸带生态环境现状,开展水环境调查和生物群落调查,根据调查结果开展水质、沉积物及生物群落多样性等评价,提出相应的生态修复建议,并提出适合一般海岸带生态修复的基本设计思路。研究结果表明:该研究区无机氮和活性磷酸盐超标,水体质量较差,不利于浮游植物生长,底栖动物生态环境受损。结合生态环境现状,建议开展以种植红树林为主的生态修复,增加红树林物种类型,优化群落结构。Coastal ecological environment is a complex ecosystem.Due to the diversity of ecosystem structure and function,ecological restoration needs to adapt to local conditions and formulates ecological restoration measures suitable for localization.By analyzing the current situation of the ecological environment in the coastal zone of Humen Bridge in Guangzhou,the investigation of water environment and biological community in the coastal zone on the north side of Humen Bridge were carried out.According to the investigation results,the evaluation of water quality,sediment and biological community diversity were carried out,the corresponding ecological restoration suggestions were put forward,and the basic design ideas suitable for general coastal ecological restoration were put forward.The results showed that the inorganic nitrogen and active phosphate exceeded the standard,and the water quality in the study area was poor,which was not conducive to the growth of phytoplankton and the ecological environment of zoobenthos was also damaged.Combining with the current situation of habitat,it was recommended to carry out ecological restoration based on planting mangroves,and increase the species types of mangroves and optimize the community structure.
