ABSTRACT

Background

Rapid urbanization has greatly changed land-use patterns in many estuarine areas around the world, including the Guangdong–Hong Kong–Macao Greater Bay Area (GBA) resulting in serious water pollution and ecosystem degradation. Shenzhen City has conducted comprehensive ecological management and restoration in the Shenzhen Bay since 2007. The natural vegetation consisting of mangroves, semi-mangroves, wetland plants, and terrestrial plants were restored from the bund to the inner bank of the Fengtang River. Rain and sewage flow diversion systems were established. The non-point source and point-source sewage are now treated in municipal sewage treatment plants, then naturally flow through the constructed wetland, and then through a natural wetland, restored natural embankment, and finally through mangrove communities substantially improving water quality.

Result

The restoration of the wetland has increased animal and microbial diversity and has supported the establishment of a complex and stable food web. With water purification and habitat restoration, the number of alien invasive plants in the estuarine ecosystem has decreased, and the diversity of native species of birds, fish, macrobenthos, amphibians, and reptiles has increased.

Conclusion

These improvements indicate that human beings and nature can coexist in support of the sustainable development of Shenzhen City.

环境整治促进华南深圳湾口生物多样性恢复

摘要

背景

快速的城市化进程极大地改变了世界许多河口地区的土地利用模式，包括粤港澳大湾区（GBA），导致严重的水污染和生态系统退化。深圳市自2007年起对深圳湾进行全面生态治理和修复，外滩至凤塘江内岸恢复了红树林、半红树林、湿地植物、陆生植物等自然植被。建立雨污分流系统。面源和点源污水现经市政污水处理厂处理后，自然流经人工湿地，再流经天然湿地，恢复天然堤岸，

结果

湿地的恢复增加了动物和微生物的多样性，并支持建立一个复杂而稳定的食物网。随着水的净化和栖息地的恢复，河口生态系统中外来入侵植物的数量减少，鸟类、鱼类、大型底栖动物、两栖动物和爬行动物的本土物种多样性增加。

结论

这些改善表明人与自然可以共存，支持深圳市的可持续发展。
