摘　　要：海岸带景观动态是海岸带综合管理的重要方面。本文利用多时相遥感影像解译的土地利用数据研究了1994—2005年快速城市化阶段上海海岸带的景观动态变化特征。结果表明:人类干扰导致了海岸带景观的破碎化程度增加,斑块隔离程度加大,景观多样性增大;海岸带基质景观(即农田)的面积持续减少,优势度明显降低,破碎化加大,反映城市化的人工景观类型(如工业用地、交通用地、公共设施用地、居住用地)面积不断增加,成为第二大景观类型,其他用地(主要是在建用地)的面积不断增加,显示出海岸带仍在经历快速城市化过程;导致海岸带景观变化的驱动力主要是国家政策、地方政府的决策、上海市的快速城市化,以及沿海大型开发项目(如浦东国际机场、洋山国际深水港、上海化学工业区等)。在分析海岸带城市化带来的生态环境后果的基础上,建议实施综合海岸带管理以实现海岸带的可持续发展。Coastal zone＇ s landscape dynamics is recognized as one of the important aspects of integrated coastal management. In this paper, the land use datasets derived from time series aerial images were employed to study the coastal landscape dynamics of Shanghai from 1994 to 2005, the period of rapid urbanization. During this period, human disturbances caused landscape fragmentation and isolation, and increased landscape diversity. The area of main landscape （ agricultural land） continued to decrease, its dominance declined, and became more fragmentation; while the areas of artificial landscapes reflecting urbanization （e. g. , lands for industry, traffic, public facility, and residence） increased, becoming the second dominant landscape type. The increasing area of other land uses （ mainly constructing sites） implied that this coastal zone was still undergoing rapid urbanization. Central government policies, local government decision-makmade to promote the sustainable development of Shanghai coastal zone.
