【摘要】 参考Costanza以及谢高地等人提出的生态系统服务价值系数,制定了符合城市生态系统的服务价值系数。基于重庆主城区1993年、2000年和2004年3期土地利用/覆被(LUCC)变化数据,对重庆主城区的生态系统服务价值进行了分析,结果表明:重庆变为直辖市后,耕地、林地大量向城市建设用地转化,城市生态系统服务价值急剧降低,1993年重庆主城区总服务价值为564.75×10~6元,2004年为387.71×10~6元,下降了31.3%。生态服务价值系数的变化对生态系统服务的影响缺乏弹性,水域和林地面积变化对重庆主城区生态系统服务影响明显。更多还原

【Abstract】 Referring to the coefficient of the ecosystem service values put forward by Costanza and Xie Gaodi,the paper develops the coefficient of ecosystem service values that is suiTablefor urban areas.Based on the changes of the three land Use/Cover(LUCC) data of Chongqing in 1993,2000,and 2004,it analyzes the ecosystem service values in the urban area of Chongqing City.The results show that since 1997 when Chongqing became a municipality,a large number of farmlands and woodlands have been used for urban construction, and the total service value of this city has been decreasing sharply,which decreased from 56.475 million yuan in 1993 to 38.771 million yuan in 2004,decreasing by 31.3%.Such data prove that the change of the coefficient of ecological service values doesn’ t have a dynamic effect on the ecosystem services,while the change of waters and woodlands has an outstanding influence on the ecosystem services in Chongqing City.更多还原
