Ecosystem Service Values Based on the Land Use and Land Cover Change in Sanya

Based on the MapGIS 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.
