摘要
伴随着大规模的围海造地活动,"蓝色土地"成为沿海各地发展新的经济增长点。然而,人类大规模开发近岸陆域带资源的行为已经严重改变了原有的海岸动力系统,致使海岸防线以及海岸生态环境遭受巨大的破坏,海岸灾害隐患进一步加剧,大规模的围海造地和港城建设活动给沿海生态环境带来更为巨大的压力。另一方面,合理开发利用滩涂资源已成为国家开发的一项战略措施。通过对江苏省盐城市开展沿海滩涂变化监测试点工作,结合"十五""十一五""十二五"省级基础测绘、第一次地理国情普查、行业专题等多时期、多类型数据,重点对沿海边界线变化进行监测分析,为合理开发利用滩涂资源提供科学依据。
Accompanied by reclaiming land from seawaters in large-scale activities, the "blue land" become a new economic growth point around the coastal development, however, all human behavior has been large-scale development of nearshore zone for land resources is to change the original coastal dynamic system, and the coast defence were severely damaged, huge damage to the coastal ecological environment, intensifying coast hazard, reclaiming land from seawaters in large-scale and harbour city construction activities bring great pressure to the coastal ecological environment, and the reasonable development and utilization of tidal flats resources has become a national development of a strategic measures. This article through to yancheng city in jiangsu province to carry out the pilot work for monitoring coastal shoal changes, combined with "tenth five-year plan""eleventh five-year plan""twelfth five-year plan" basic surveying and mapping, geographical conditions for the first time at the provincial level census, multi-type data, industry project period, the key monitoring analysis was carried out on the coastal boundary changes, provided the scientific basis for reasonable exploitation and utilization of tidal flats resources.
