| 摘 要： | 基于遥感和地理信息系统的方法与技术，以1980、1990、2000和2010年4个时期为特征年，对近30年来我国大陆海岸线时空变化特征进行了分析研究。结果显示:（1）海岸类型转化显著，人工岸线所占比例由1980年的24.6%上升到2010年的56.1%；（2）海岸线变化呈现显著区域特征，变化较剧烈的区域集中在珠江口岸段、长江口-杭州湾岸段、海州湾-吕四段、滦河口-潍河口段及辽河口-葫芦岛港段；（3）3个时期相比，海岸开发由早期的围垦养殖向后期的城镇建设和海洋运输开发方式转变，并且这种转换方式在南方早于北方。

| Abstract: | This paper is mainly focused on the continental coastline changes of China in the span of 1980-2010. Remote sensing images of Landsat MSS, TM and ETM+in the year of 1980, 1990, 2000 and 2010 are processed to extract coastlines and land use in the gap of coastline changes. Based on the technology of RS and GIS, the spatial and temporal changes of coastline are analyzed, the result show that: (1) the coastline type changes significantly, the length of artificial coastline in 1980, 1990, 2000, and 2010 occupies 24%, 39.3%,49.4%and 56.1%, respectively; (2) the coastline change shows a significant regional characteristic, coastline changed significantly in the coast segment of the Zhujiang Estuary, the Changjiang Estuary to the Hangzhou Bay, the Lvsi Port to the Haizhou Bay, the Weihe to the Luan Estuaries and the Liaohe Estuary to the Huludao Port; (3) comparing the three sub periods of the research span, a coastal reclamation is mainly focuses on an urban construction and a maritime transport in the later period while focuses on aquiculture in the earlier period; from the north to the south, the changes of continental coastline of China show significant temporal and spatial heterogeneity. |
