The Research on the Farmer Households' Economic Behavior and Sustainable Utilization Issues in Tidal Flat of Jiangsu Province

摘要

Associated with the overexploitation of coastal resources, a set of problems has been brought out, for example, unreasonable land reclaiming, overdeveloped urbanization, heavy agriculture pollution, etc. The research on sustainable use of coastal tidal flat has been increasingly emphasized. Farmer household is a relatively independent unit in coastal rural economic activities, which creates noticeable impacts on the coastal wetland ecosystem. The present research takes Sheyang and Dafeng counties of Yancheng City as research areas. The three different villages have been surveyed for the purpose of numerical economic model development. 220 farmer households were interviewed to support the model building. Besides, the correlation model between farmer households' economic behaviors and environmental impacts has also been developed. The research shows that the farmer households' economic behaviors have direct impacts on the ecological quality of the coastal tidal flat. The other determinants to the local coastal ecological quality are the areas of land with economic activities, land use types, investment of production, investment intention, individual education level etc. Finally, the main problems and environmental stresses are analyzed and management approaches are proposed in the paper.
