　　研究安康市土地利用变化及其环境效应，为区域土地的可持续利用提供科学依据。基于2002年和2008年2期的土地利用详查数据，采用单项土地利用动态度，对安康市2002-2008年土地利用的变化进行了定量分析；应用Costanza等人提出的生态服务价值计算方法，参照国内学者谢高地制定的中国陆地生态系统单位面积生态服务价值当量，估算了安康市土地利用变化对生态系统服务功能的影响。结果表明，2002-2008年安康市生态系统服务价值净增加77393.29×104万元，土地利用对生态系统服务功能具有正效应；其中林地对生态系统服务贡献率高达85%以上，这一比例在研究期进一步提高；生态系统单项服务功能除废物处理和食物生产外均呈现增长的态势。

The objective of paper is to analyze the land use change and the environment effect in Ankang,it provides the scientific basis for the sustaintion of the region land use. It has carried on the quantitative analysis to the land use change of Ankang from 2002 to 2008 by means of using the single item land utilization dynamic ics in two issue of land use sifted the data based on 2002 and 2008; by the table of our country ecosystem service value per unit area of different ecosystem types of Xie Gao Di and using formula proposed by Costanza, the ecosystem service value of Ankang city and its change were calculated and analysed, The result indicated that the net ecosys-tem service value of Ankang gains 77393.29 * 108 Yuan from 2002 to 2008, the land utilization has the effect to the ecosystem service func-tion; And the forest land reaches as high as above 85% to the ecosys-tem service technical progress factor; this proportion further enhances in the research time; The ecosystem single item service function pre-sents the growth besides the waste treatment and food production the situation.
