摘　　要：广西北海市合浦县党江镇南流江入海口红树林遭受鱼藤危害。鱼藤通过攀援覆盖,蔓延成灾,导致连片红树林植物枯死,从而破坏了红树林生态系统。鱼藤是红树林常见攀援类伴生物种,在全球变化背景下,局部地区鱼藤已变成了危害红树林湿地的"植物杀手",急需采取措施保护受危害的红树林湿地。The damage to mangrove forest by Derris trifoliate occurred at the estuary of Nanliu River in Dangjiang Town, Hepu Country, Beihai city, Guangxi. And it was not reported before. The mangrove forest in Dangjiang Town plays an irreplaceable role in the ecological system of Beibu Gulf zone. Derris trifoliate climbs over the mangrove trees and weakens photosynthesis of the mangrove trees, leading to die back of the mangrove trees. Derris trifoliate can produce roots when it touches soil and spreads quickly, but it has no main root. The invasive plant has caused disastrous damage by its spread. The mangrove ecosystem has been severely destroyed. And the damage will be difficult to restore in a short time. Derris trifoliate is a common climbing plant associated with mangrove trees. In the context of global change, the growing conditions of Derris trifoliate have also been affected. In some areas, Derris trifoliate has become the ＂plant killer＂ in mangrove forest wetland. It is in urgent need of taking measures to protect the damaged mangrove forest wetland.
