摘    要:选取了厦门市1986年,1993年和2003年三个时期遥感影像解译数据作为基本信息源。在ArcGIS支持下,应用GIS技术获取滨海湿地基本数据,通过对景观格局指数的计算和分析,对过去17年间厦门滨海湿地的景观格局变化特征进行了研究。结果表明:湿地总面积呈下降趋势,由1986年的419.764km^2下降至2003年的394.237km^2,湿地斑块数量由1986年的810块增加乍2003年的1092块。湿地景观破碎度不断增加,而研究区域湿地景观多样性指数和均匀度指数则下降。

关 键 词:滨海湿地  景观格局  变化  厦门

Abstract:In this paper,three Landsat TM images(respectively obtained in1986,1993 and 2003) were interpreted as basic information sources.And the basic data of coastal wetland were obtained with the application of GIS-tech supported by ArcGIS.By calculation and analysis of the landscape pattern index(LPI),the change characteristics of LPI of coastal wetland over the past 17 years were studied.The study shows that there is a decrease in wetland area,from the 419.764 km2 in 1986 to the 394.237 km2 in 2003,with an increase in wetland patcheness,from 810 of 1986 to 1092 of 2003,the landscape fragmentation index of wetland is continuously rising,while the diversity and evenness are decreasing.
Keywords:Coastal wetland  Landscape pattern  Change  Xiamen city
