摘要
根据自然地理、海洋动力、生物等特征!本文研究受大河作用的大丰潮滩地貌、沉积过程,讨论老黄河和长江对该潮滩发育的影响和潮滩生物群落空间分布及演变规律。本文评价了大丰潮滩开发利用现状,分析了它们的经济效益和环境效益,提出把目前受到强烈改造、过度利用的模式改变为顺应潮滩自然演变、有步骤合理开发利用潮滩的模式。
On the basis of the characteristics of physical geography, marine dynamics and biology of Dafeng coast, this paper makes a study on the geornorphological and sedimentary processes of the tidal flats of Dafeng affected by larg rivers, discusses the influence of the old Huanghe River and Changjiang River in the area, and expounds the space structure and evolution of the ecological communities of the tidal flats. This paper also reviews the current state of the exploitation of the tidal flats and their economic and environmental benefits. According to the understanding of the characteristics of the natural ecosystem, a rational exploitation model of the tidal flats of Dafeng was proposed.
