近25年来是海峡西岸省会中心城市——福州市发展最为快速的时期.基于RS和GIS技术,利用1988,2000和2012年福州市三期的土地利用图为数据源,运用景观生态学原理,借助ArcGIS和FRAGSTATS软件技术,选取城市景观构成、斑块面积、斑块密度、景观分离度指数、多样性指数和均匀度指数,同时结合新型景观指数PPU和SqP(sq)等指标,分析福州市24年来城市景观格局演变.结果表明,从1988年到2012年间,福州市景观格局以林地为基质景观,其优势度指数最高,分离度指数最低;城市建设用地向西、向南扩张明显,城市分维数、景观多样性和景观均匀度都呈增加趋势;耕地、城镇村及工矿用地和水域的破碎化程度提高,未利用地破碎度最低;建设用地与耕地、水体之间转移量大,减少的耕地和水体主要转化为建设用地.

The latest 25 years isthe most rapid period of development in Fuzhou which is the capital city lies in the West Coast.Based on the theory of landscape ecology and the technology of RS and GIS,using the land use maps of Fuzhou city in 1988,2000 and 2012as three data sources.The structure of urban landscape,the average area of patches,patch density,fractal dimension,isolation index,landscape diversity and evenness index are chosen,at the same time,the new landscape index PPU and SqP(sq)as well as other indicators were used to analyze the dynamic evolvement of landscape pattern with ArcGIS and FRAGSTATS software in Fuzhou city during the 24 years.The results showed that from 1988 to 2012,the forest land was the matrix landscape in Fuzhou,and the value of dominance was the highest,while the division value was the lowest.The urban construction landobviously expanded to the west and south direction.Fractal dimension、landscape diversity and landscape evenness trended to increase,the fragmentation index of farmland,urban village and industrial land and waters increased significantly, the fragmentation index of unused land was the lowest.The area of construction land,cultivated land and water transferredlargely.The reduction of cultivated land and water region mainly converted to building land.
