船舶兴波导致红树林生态系统退化的机理

Mechanisms on Mangrove Ecosystem Degradation from Waves by Boats

通过分析波浪在林内和光滩上传播途径,阐述了船舶引起的频繁巨浪造成红树植物死亡、林内动物种群和数量减少、滩涂断层及红树植物难以自然扩展等生态系统退化机理;在此基础上提出消除和减少船舶兴波对红树林生态系统危害的有效对策。

In this paper, different paths of wave spreading in the bare mudflat and vegetated areas were analyzed, and damages from boat-generated waves to mangrove ecosystems were summarized as follows： the death of mangrove plants, decrease of benthic animal species and quantity, erosion of tidal flat, restriction of mangrove natural extension. Finally, some feasible strategies were pro- posed to eliminate and/or reduce hazards from boat-generated wave to mangrove ecosystems.
