厦门环同安湾海岸带景观空间格局动态变化分析

利用遥感和地理信息技术,运用平均斑块面积与分离度指数、多样性指数、破碎度指数、优势度指数和分维数等景观格局指数,以厦门环同安湾区1989年、1997年和2007年3个时期遥感影像解译数据作为基本信息源,对过去18年间环同安湾海岸带的景观格局的时空变化过程和演变趋势进行了研究。结果表明：1989—2007年,农田面积大量...

Analysis on Spatial Pattern Dynamic Changes of Coastal Landscape Surrounding Tong＇an Bay in Xiamen

In this paper,with the help of RS and GIS technology,mean patch area and resolution index,diversity index,fragmentation index,dominance index,fractional dimension index and other landscape pattern indexes were used to study the spatio-temporal variations and evolution trend of the coastal zones surrounding Tong＇an Bay over the past 18 years.Three RS images（respectively obtained in 1989,1997 and 2007） of this region were interpreted as basic information sources in the study.The results showed that the cultivated land seriously decreased and mainly transformed to construction land from 1989 to 2007.The proportion of the area of agriculture land and forest which had be dominant in landscape pattern declined continuously.The patch area of artificial landscape such as land for towns and villages had been increasing,and their patches had been congregating.The regional landscape was becoming more fragmental and diversity index and fragmentation index increased continuously,which presented the increase of human disturbance.
