THE ECOLOGICAL SYSTEM AND THE EXPLOITATION MODEL OF TIDAL FLATS--A CASE STUDY OF THE TIDAL FLATS OF DAFENG COUNTY, JIANGSU PROVINCE
潮滩生态特征及开发利用模式——以江苏大丰潮滩研究为例

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.
