福州市生态系统服务价值对土地利用变化的响应研究

Responses of the Ecosystem Service Value to Land Use Change in Fuzhou City

根据福州市3期（1988年、1999年和2008年）遥感影像解译数据,采用Costanza生态系统服务价值计算公式,并参照谢高地等人的中国陆地生态系统单位面积生态服务价值表,分析了福州市土地利用变动及其对生态系统服务价值的影响.结果表明：1988~2008年福州市建设用地急剧扩展,耕地、林地和未利用地面积相应缩减,导致生态系统服务价值不断下降.福州市1988年、1999年和2008年的的生态系统服务价值分别为16.60亿元、16.69亿元和15.60亿元,从1988~2008年间减少了1.01亿元.敏感性分析表明,福州市生态系统服务价值相对于生态价值系数来说是缺乏弹性的,说明研究可信.

According to the Interpretation data of Remote Sensing Images（1988s,1999s and 2008s） in Fuzhou City,using Costanza＇s calculation formula of ecosystem service value and referring to Xie Gao-di＇s table of every unit area＇s ecosystem service value to China land,this paper analyses the land use change and appraises its effect on Ecosystem Services Value（ESV） in Fuzhou City.The results show that the area of construction land rapidly extended and the area of cultivated land,woodland and unused land decreased from 1988 to 2008.Therefore,the total value of ecosystem services in Fuzhou City declined.in 1988 the total value of ecosystem services 1.660 billion,in 1999 for 1.669 billion,in 2008 for 1.560 billion,from 1988 to 2008 the total value of ecosystem services decrease by 0.101 billion.The sensitivity analysis suggested that these estimates are relatively robust.
