摘要 海岸沙地生态系统是海岸带陆地、海洋和大气交互作用形成的典型生态系统,具有重要的服务功能和价值。本文通过对国内外文献进行综述,认为海岸沙地生态系统主要具有3个功能:(1)海岸地区的天然防护屏障;(2)生物多样性的保护基地;(3)滨海旅游服务的基础。探讨了海岸沙地受到破坏的主要原因及其保护面临的挑战,认为海岸沙地生态系统服务价值评估的不确定性以及构成的不对称性,是其保护面临的最大挑战。未来需要加强对海岸沙地生态系统服务价值的准确评估,在此基础上制定合理的保护政策,将海岸沙地的保护和开发结合起来,充分发挥海岸沙地生态系统的服务功能,为海岸地区的可持续发展提供依据。 Coastal dunes ecosystems are typical ecosystems formed by the interaction among land,ocean and atmosphere,and have important ecological functions.All the published papers about ecological functions of coastal dunes were reviewed and we believed that there are 3 main ecological functions for the coastal dunes:natural protective barrier in coastal areas,conservation bases of species biodiversity and basis for seaside tourism service.Furthermore,primary reason for the destroy of coastal dunes and challenges faced for its protection were discussed,the results suggested that evaluation uncertainties of ecological service value and its unbalanced constitution in coastal sand dunes were the two chief challenges.So accurate evaluation of ecological services in the coastal dunes should be enhanced,by which reasonable protection policies should be formulated,protection and development of coastal dunes must be combined together,which will favor the adequate play of ecological function services in the coastal dunes,and provide some useful suggestions for the sustainable development of coastal areas.
