摘　　要：土地利用变化及生态敏感性研究已经成为当前土地研究的热点问题之一。本文以交口县为例,通过土地利用动态度、生态系统服务价值和单项生态系统服务价值对土地利用变化及生态敏感性进行分析。结果表明:2009-2013年,交口县耕地、建设用地面积持续增加;生态系统服务总价值减少16.9473×105元。在单项生态服务价值中,气体调节、气候调节、土壤形成与保护、生物多样性保护、原材料这5个单项服务价值减少,水源涵养、废物处理、食物生产、娱乐文化这4个单项服务功能价值呈现U型变化,先减后增。生态系统服务价值的敏感性指数都小于1,说明交口县的ESV对VC是缺乏弹性的,即生态系统指数的变化对生态系统服务价值的影响不大。Study on land use change and ecological sensitivity has become one of the hot spot issues in current land research. Taking the Jiaokou County as an example, by measuring the dynamic degree of land use, the value of ecosystem service and the single value of ecosystem service, this paper researched the change of land use and ecological sensitivity. The experiment results indicated that the quantity of agricultural acreage and construction land in Jiaokou county kept growing; the number of ecosystem service value dropped by 1,694,730 yuan from 2009 to 2013 years. In the single value of individual ecological services, the value of gas regulation, climate regulation, soil formation and protection, biodiversity protection and the raw materials decreased, however, the functional value of water conservation, waste treatment, food production and errtertainmerrt culture, had a U-shape curve which presented an increase following a decrease. The sensitivity index of ecosystem service value was less than 1f indicating that the ESV was inelastic to VC in Jiaokou county and the change of ecosystem index had little impact on ecosystem service value.
