【摘要】 滩涂围垦是基础设施建设占用大量耕地情况下江苏省实现耕地总量动态平衡的主要途径之一,随着社会经济的发展和对土地需求量的不断增加,滩涂围垦与海岸带环境保护之间的矛盾日渐突出。但以实现耕地总量动态平衡为目的的滩涂围垦需要以滩涂总量动态平衡为前提才能保证滩涂资源的可持续利用。通过对江苏海岸的发育和围垦历史以及淤蚀动态的分析,提出以滩涂总量动态平衡为前提的滩涂围垦适宜速度,并对江苏海岸不同岸段的适宜围垦速度进行计算分析,提出围垦活动的强度应当同时综合考虑围垦后的经济和社会效益与拟围滩涂所在岸段的自然淤蚀状况(即滩涂的承载力),以实现同时满足围垦活动与滩涂资源保护的平衡。更多还原

【Abstract】 Reclamation of tidal flat is one of the main ways to get a dynamic balance of the total amount of plowland. With the development of social economy and the increasing demand for plowland, the contradiction between tidal flat reclamation and environment protection becomes more and more outstanding. However ,tidal flat reclamation should also follow the dynamic balance of total amount of tidal flat amount. The paper analyzed the history of reclamation and development of Jiangsu mud coast, and calculated the feasible rates of tidal flat reclamation on different stretches respectively, and pointed out that both the economic social benefits of reclamation and the natural erosion-accretion conditions of the coasts should be taken into consideration in deciding the intensity of tidal flat reclamation, so as to satisfy demands on both reclamation and protection of tidal flat resource.更多还原
