摘要
近百年来江苏沿海进行了大规模的滩涂围垦开发。本研究评估了近代以来江苏沿海滩涂围垦历史演变情况,分析其演变机理。研究搜集整理了清末至今多种历史地形图、地方志、遥感资料,利用统计分析以及空间分析,定量地揭示近百年来江苏沿海围垦时空变化,并简要分析变化背后的机理。研究结果表明:(1)在围垦的时间分布上,不同时期的历史围垦程度不同,其中民国时期1910年代和解放以后的1950年代的围垦规模分别为解放前和解放后的两个围垦高峰时期;(2)在围垦的空间分布上,总的来说,盐城市围垦面积最大,总量占全省总围垦面积近70%,南通、连云港市相对较少,而沿海三市围垦面积排名前五名的分别是大丰市、射阳县、连云区、响水县、如东县;(3)从围垦特点看,空间缓冲区分析显示历史上江苏沿海围垦多为鱼鳞似的圈围,用途则以农业生产、水产养殖、国营盐场为主,工业用地、港口建设用地大大不足,用地综合效益不高。
The large-scale tidal flats have been reclaimed in the Jiangsu coastal areas during the last century. The purpose of this study is to evaluate and analyze the historical evolution of Jiangsu coastal reclamation. A variety of historical maps, local chronicles and remote sensing data are collected and collated since the late Qing Dynasty, and statistical analysis and spatial analysis are used to examine the temporal changes over the past century. The results are shown as follows. （1） The 1910s and 1950s are two relatively high-density periods before 1949 and after 1949. （2） The reclamation lands are mostly distributed in Yancheng, accounting for 70% of the total in Jiangsu coastal areas, and they are relatively small in Nantong and Lianyungang. In terms of the reclamation areas, the top five counties are Dafeng, Sheyang, Lianyungang, Xiangshui, and Rudong. （3） Buffer zone analysis shows that the pattern of Jiangsu coastal reclamation is like a mosaic fish-scale shape, and the reclamation lands are mainly used for agriculture, aquaculture, and salt industry, while less are used for industrial purpose and port construction.
