郑州市郊区生态服务功能价值变化研究

Study on the Change of Ecosystem Service Function Value in Zhengzhou Suburban

利用1997年TM影像、2001年和2005年SPOT影像解译获得的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。

Land use data of the year 1997, 2001 and 2005 in Zhengzhou suburban are studied with the aid of GIS and remote sensing techniques. The ecosystem service function value and change is estimated by adopting displacement cost method, market value method and so on in this paper. The result indicates that the ecosystem service function of all the districts is dropping. Among which the change of Jinshui district, Zhongyuan district and Guancheng district are the most obvious.
