摘要
选取闽三角地区2000年、2005年、2010年的Landsat TM和2015年的Landsat Oli影像,采用人机交互的方式对影像进行解译,提取多时相土地利用类型数据,计算土地利用动态度,结合生态系统服务价值及敏感性分析,系统分析了闽三角地区土地利用变化下的生态系统服务价值变化特征.研究结果表明:研究期内,林地和耕地面积一直处于减少的状态,建设用地面积处于持续增长的状态,后10 a的土地利用变化速度相对前5 a有所加快.生态系统服务价值呈逐渐下降趋势,总的生态系统服务价值2015年比2000年少了47.61×10~8元.各个土地利用类型生态系统服务价值敏感性指数都小于1,表明生态系统服务价值对生态系统服务价值指数缺乏弹性,研究结果可信.
TM images in 2000,2005 and 2010,OLI images in 2015 in Min Delta were selected,the remote sensing images were interpreted by the way of human-computer interaction,and extracted the multi temporal land use data,calculated land use dynamic degree,combined with ecosystem service value（ ESV） and sensitivity analysis,this paper systematically analyzed the spatial variation characteristics of land use and ecosystem services value in Min Delta. The results indicated： in the study period,the area of forest land and cultivated land has been in a reduced state,and the area of construction land remains in constant growth. From the synthetic,the land use change after ten years of relatively large compared with the first five years. In terms of ESV,ESV showed a downward trend during the study period,and in 2015 was 47. 61 billion Yuan less than that in 2000. The sensitivity index of ecosystem services value of each land use type is less than 1,which indicates that ecosystem service value is not flexible to ecosystem service value index,and the research result is credible.
