中文摘要：

基于Map GIS K9,选取2004年、2009年和2014年3期Landsat遥感影像为主要数据源,运用土地利用动态度模型、土地利用程度指数和Costanza生态系统服务价值计算公式,研究了三亚市生态服务价值及其敏感性对土地利用变化的响应.研究表明2004~2014年三亚市土地利用变化的主要趋势是林地和耕地向建设用地和园地转化;三亚市2014年生态服务总价值较2004年减少了2.834亿元,变化率为-3.98%;人均生态系统服务价值同样为下降趋势.

英文摘要：

Based on the Map GIS K9 software,the three periods Landsat satellite remote sensing images of Sanya City（ 2004,2009 and 2014 year） were used as the main data source,and the land use dynamic degree model,the land use degree index and the calculation formula of Costanza ecosystem service values were used to analyze the response of ecosystem service values,sensitivity index to the land use change characteristics. The results showed that from 2004 to 2014,in Sanya,the main trend of land use structure is the transition from woodland and farmland to construction land and garden plot; compared with that in 2004,the total ecosystem services value in 2014 is decreased by 3. 98%; the ecosystem services value per person appears to be decreased.
