摘　　要：基于厦门市1987、1992、1997、2002和2007年5期Landsat TM影像,采用RS、GIS和统计分析的方法,对当地1987-2007年的土地利用/覆被时空变化特征进行分析,阐明土地利用变化的主要驱动力,提出区域土地资源可持续利用的政策建议。研究结果表明:(1)厦门市在1987-2007年间,耕地数量大幅减少286.3km2,建设用地和裸地分别增加216.7km2和75.6km2;(2)土地利用强度呈现逐年增加的趋势;(3)快速工业化、交通扩张、产业结构调整和土地利用政策对于厦门市土地利用/覆被变化具有显著的影响。为了实现当地土地资源的可持续利用,需要以生态学思想为基础,遵循自然生态法则,确定最佳的土地利用方式。Based on the Landsat TM image data in 1987,1992,1997,2002 and 2007,using RS、GIS and statistical analysis methods,the temporal and spatial characteristics of land use/cover change in Xiamen were analyzed.The aim of this paper was to clarify the main driving forces affecting land use/cover change,furthermore,to provide scientific basis for the sustainable use of land resources.The results showed that:(1) Arable land in Xiamen during the last 20 years was significantly reduced by 286.3km2,while construction land and bare land increased by 216.7km2 and 75.6km2,respectively.(2) Both the land use intensity and land transition velocity showed an increasing tendency.(3) Rapid industrialization,transportation expansion,industrial restructuring and the transform of land use policy played an important role in the process of land use/cover change.It was needed for achieving sustainable use of urban land resources to confirm the optimum land-use structure,following ecological principles and ecology ideology.
