摘　　要：江苏沿海滩涂土地资源丰富,其中盐城市海岸线占全省的56%,滩涂资源接近46万hm2,滩涂围垦活动较为频繁,滩涂围垦与开发是盐城市重要的土地利用模式,也是耕地占补平衡的重要手段。该研究分析了盐城市沿海滩涂土地利用现状,研究其土地利用的结构变化和空间变化。结果表明:盐城市沿海滩涂围垦区农用地、建设用地、未利用地规模不断增加,但是未利用地增速远超于农用地和建设用地增速,说明滩涂开发速度超过利用速度。The resources of coastal beach is very abundant in Jiangsu Province, the coastline in Yancheng accounts for 56 percent longer than Lianyungang and Nantong, and the coastal beach is close to 46 million ha. The activities of inning fiats is frequently, have become one of im- portant land use pattern, and approach to keep the amount of field acreage an appropriate level. The paper analyzed the current coastal beach land use, studied on land use structure change and spatial - temporal change. The study indicated that agricultural-land building-land and un- used-land increased quickly, but the speedup of unused-land far faster than the speedup of agricultural-land and building-land, meaning that the exploitation of coastal beach exceeding the utilization of inning flats.
