摘要: 江苏海岸带位于我国沿海中部,有广阔的海涂,丰富的土地、生物和水资源,以及充裕的劳动力。但资源分布不均,目前的利用效率也不高,开发潜力很大。海岸带土地利用具有以下四方面的特点,即:利用类型的多样性,地域分布的差异性,各种类型之间的联系性以及利用方式的变动性。研究这些特点,有助于海岸带资源的合理开发利用。

Abstract: Most of the coastal land of Jiangsu Province came into being due to the coast advance caused by the capture of the Huaihe River by the Huanghe River in the 12th century, consisting of two parts: the alongshore land about 10-20 kilometers in width and the tidal flat of about 4800 square kilometers. By centuries management it has been developed into an intensive farming area in which salt industry and aquatic products industry have been developed to some extent. The land use in this area influenced by natural features,resource structure and human activities is characteristic of the following. 1) The land use patterns in the area are more diverse than in contiguous inland area. 2) Different segments have different land use patterns. Salt industry are dominant sector in northern part, while cultivation and aquatic products industry in southern part. 3) All patterns of land use are interrelated and interact on each other, benefit or restrict each other. 4) The land use patterns are easy to change with natural and socioeconomic conditions. One must keep the above characteristics in mind when making project for using and developing the coastal land. In order to change the sigle-product economic situation we should pay attention to not only the dominant sector of certain segment but also the comprehensive utilization of natural resources.
