摘　　要：基于闽三角地区2000年、2005年、2010年和2015年的LandsatTM/ETM+/OLI影像提取农田景观数据,并利用景观格局分析方法,从景观面积、空间分异、斑块特征以及总体格局4个方面,对比研究了2000—2015年闽三角地区农田景观格局的演变特征,并对其生态服务功能进行深入探讨。研究结果表明:2000—2015年间,闽三角地区的农田景观以平原水田和丘陵水田为主,面积呈现出整体下降的趋势,其空间分布格局基本保持稳定,集中分布于东南沿海一带,地域上主要集中于泉州市和漳州市;丘陵水田和平原水田的斑块数目最多,斑块面积最大,而平原旱地和山区旱地的斑块数目最少,斑块面积也最小,其中丘陵水田和平原水田更为集中连片,景观破碎化程度较低;农田景观格局呈现出破碎度增加、丰富度下降、类型单一化以及聚集度下降的总体趋势;闽三角地区的农田景观格局演变会降低其供给、调节、文化以及支持等生态服务功能。In this paper,Landsat TM/ETM+/OLI in 2000,2005,2010 are selected to extract farmland landscape data in Fujian Delta region and landscape pattern analysis method is adopted to comparatively study the evolution characteristics of farmland landscape pattern in Fujian Delta region,and to discuss its ecological service functions deeply from 4 aspects of landscape area,spatial differentiation,plaque characteristics and overall pattern.The results showed that the farmland landscape of Fujian Delta region was mainly composed of plain paddy fields and hills paddy field from 2000 to 2015.The area of paddy field showed an overall downward trend and it concentrated in the southeast coastal area,mainly in Quanzhou city and Zhangzhou city;and its spatial distribution pattern was basically stable.The number of patches of hilly paddy field and plain paddy field is largest and its patch area is the widest,while the number of patches of plain dry land and dry land in mountain area is the least and its patch area was also the least,and the degree of landscape fragmentation of hilly paddy field and plain paddy field was lower.Farmland landscape pattern showed a general trend of increasing fragmentation,decreasing richness,simplifying landscape types and declining aggregation degree.The evolution of farmland landscape pattern can affect the ecological service functions in supply,regulation,culture and support.
