| 摘 要： | 利用4期(1987年、2002年、2007年和2012年)TM/ETM遥感影像,运用GIS空间分析技术生成连云港海岸带区域4期土地利用类型图,然后应用景观格局分析软件Fragstats 4.1分析连云港海岸带的景观格局变化。同时收集连云港海岸带的相关社会经济统计数据进行分析,探讨了景观格局变化的人文驱动因子。结果表明:1987~2012年这25年间,变化较剧烈的类型是耕地和建设用地,耕地面积基本呈减少趋势;建设用地的面积基本呈增加趋势,且涨幅较大;连云港海岸带人口和第二产业快速增长带来了海岸带的大规模开发,对海岸带干扰较大。

| Abstract: | According to the TM /ETM remote sensing images at 4 stages（ in the years 1987,2002,2007 and 2012）,the author generated 4- stage figures of land- use type of coastal zone in Lianyungang by using GIS spatial analysis technology,and then analyzed the changes in landscape pattern of coastal zone in Lianyungang by using the software Fragstats 4. 1. Through collecting and analyzing the related social and economic statistical data in coastal zone of Lianyungang city,we explored the human and cultural driving factors causing the changes in landscape pattern. The results showed that： the use of arable land and construction land changed significantly in the past 25 years from 1987 to 2012; the area of arable land decreased generally,while the area of construction land increased sharply; the large- scale exploitation of Lianyungang municipal coastal zone due to the rapid growth of the population and the fast development of the second industry seriously interfered the land use of this coastal zone. |
