| 摘要: |
| 上海从20世纪80年代以来经济发展迅速,城市化进程快，加上人口剧增,使得滨海地区的景观格局已经发生了剧烈的变化.基于景观生态学理论与方法,在3S技术的支持下,通过对1994年、2003年和2007年3个时相的遥感影像图进行解译,结合Fragstats 3.3软件,在确定3个时相的最佳分析尺度后,分析出3个时相的斑块级别和景观级别的景观指数,并选取了景观层次上的2个景观指数对研究区的6个镇进行时间和空间上的对比分析,结果显示：研究区域的主导景观为农田景观,景观多样性较高且呈上升趋势;13年来,6个镇（街道）的破碎度增加,其中芦潮港镇的破碎化程度最高. |

| Abstract: |
| Since the 1980s in Shanghai,fast economic development,rapid urbanization,population explosion,all of these phenomena are driving radical changes in landscape pattern of coastal area.The landscape pattern evolution at the coastal regions of the north of the Hangzhou bay is analysed based on the landscape ecology theory and method by using Fragstats 3.3 software.3S technology is utilized to interpretate the sensing images at three phase in 1994,2003,2007,and selected two landscape index of the landscape level to study six town from time and space on the contrast analysis.The results show that farmland landscape is the dominant landscape in research area,landscape diversity is high and shows ascendant trend;For 13 years,six towns’(street) fragmentation degree increase,the Luchaogang town has the highest degree of fragmentation. |
| Key words: the north of Hangzhou bay landscape pattern the coastal region of Shanghai landscape index |
