无瓣海桑造林是否造成九龙江口生物入侵的探讨

尽快恢复和发展红树林、营造防潮抗灾能力强、生产力高的红树护岸林体系,改造沿海滩涂生态环境,是沿海防护林体系建设的主要任务。无瓣海桑是从孟加拉国引进的速生红树树种,生长快,生产力高,在较短时间内能起到保护海堤和稳定海滩的作用,但无瓣海桑毕竟是外来种,是否造成生物入侵并给滨海滩涂带来生态灾害众说纷纭。本文从入侵种的生态影响入手进行分析,认为无瓣海桑造林目前尚未造成九龙江口生物入侵。

Whether or Not the Sonneratia apetala B.Ham Plantation Caused Biological Invasion in Jiulong River Estuary

It is the main task of the coastal shelterbelt forest development program to restore and expand the Mangrove forest to establish a coastal shelterbelt forest system with strong resistance to tide disasters and high timber productivity and to improve the ecological environment of coastal land and beaches. Sonneratia apetala B. Ham is a fast growing species introduced from Bangladesh, it has fast-growth and high timber productivity. The species can be grown to protect seashores and fix beaches within relatively short period. However, Sonneratia apetala is an exotic species, whether or not it causes biological invasion and ecological damages to the coastal land is still under debate. Investigations were conducted by starting from ecological impact analysis of the species. No evidence was found that Sonneratia apetala has caused any biological invasion so far.
