摘　　要：基于闽三角地区2000、2005、2010和2015年的Landsat TM/ETM+/OLI影像提取4期的森林景观数据,从森林景观的数量特征和空间分异2个方面,对2000-2015年闽三角地区森林景观演变特征进行研究,并结合不同景观之间的相互转移和生态服务价值评估方法,对其生态服务价值的动态变化进行深入分析.结果表明:2000-2015年间,闽三角地区的森林景观面积呈现出不断减少的趋势,不同森林景观类型的面积变动存在着较大差异,且向森林景观转移最多的是农田景观,而森林景观向其他景观转移最多的是城市景观;森林景观主要分布于闽三角地区的西北内陆地带,而东南沿海地带则较为稀少,且不同县(市、区)森林景观的面积变动及其速率存在着较大差异;森林景观的生态服务价值整体上呈现出下降的趋势,减少了71 068. 1万元,其中森林景观向城市景观转移导致生态服务价值减少了71 810. 5万元,是闽三角地区森林景观生态服务价值下降的最主要因素.This paper is based on the forest landscape data that is extracted from Landsat TM/ ETM ＋/OLI images of 2000, 2005, 2010 and 2015 in Fujian Delta region, according two aspects of the number of features and spatial differentiation of forest landscape to comparatively studied its tem- poral and spatial evolution characteristics in Fujian Delta region, and then, the dynamic changes of its ecological service value are deeply analyzed. The results show that during 2000-2015, the forest landscape area in Fujian Delta region are decreased continuously, the area of different types of forest landscape changes are different, and the main type transfer into and out of the forest landscape was farmland landscape and city landscape; forest landscape mainly distributed in the northwest inland region of Fujian Delta region. While the southeast coast is more scarce, and different county （city and district） have a great difference between the area changes of forest landscape and its rate; the ecological service value of forest landscape showed a overall downward trend, a decrease of 710 mil- lion 681 thousand yuan, among them, forest landscape transfer into the city landscape ecological service value leads to a decrease of 718 million 105 thousand yuan, which is the most important fac- tor of the decline of ecosystem service value in Fujian Delta region.
