摘　　要：利用1997年、2001年、2005年郑州市郊区土地利用数据,运用替代成本法、市场价值法等测算方法,估算了其生态服务功能的价值及变化。结果表明,各区的生态服务功能整体都在下降,其中金水区、中原区与管城区的变化最为明显。各类生态服务功能中,水源涵养、净化空气和减弱噪音功能价值都较小,这也表明郑州市郊区的生态系统服务功能在城市化过程中受到较大的影响。According to the land use data of Zhengzhou suburbs in 1997,2001 and 2005,using displacement cost method,market value method and so on,the ecosystem service function value was estimated and change of the value was analyzed.The results indicated that the ecosystem service function of all the districts had dropped,and the changes of Jinshui,Zhongyuan and Guancheng distracts were the most obvious.And in the series of ecosystem services,the values of keeping waterhead,purifying air,restraining noises were very small.It also indicated that the ecosystem service function was great influenced by the urbanization process in the suburbs of Zhengzhou.Finally,some measures were proposed for improving the ecological environment in Zhengzhou suburbs.
