Land use change is a major factor affecting ecosystem services.Taking Xiamen Island as an example,the authors examine the land use patterns from 1950 to 2007 by integrating remote sensing data and evaluate the regional ecosystem services based on two revised methods so as to identify the effects and mechanisms of land use change on ecosystem services.The results showed that during 1950-2007 land use intensity of Xiamen Island had been annually rising generally.The changing trends of ecosystem service value of Xiamen Island obtained by two methods were consistent,which were decreased with the decreasing of land use intensity.Before 1987,ecosystem service value of Xiamen Island had increased by about 1.07 million yuan due to the expanding of 12.87km² water and wetland areas.Since the establishment of Xiamen Special Economic Zone in 1984,rapid urbanization has resulted in a sharp decline in ecosystem service value,and average annual loss reached to 619 773 yuan after 1987.With the utilization of land reaching saturation and launching of ecological projects,such as the Xiamen Eastern Sea Comprehensive Improvement Project,it can be predicted that decreasing trend of ecosystem service value is going to slow down in the near future.The problem of overestimating service value by correction made from a single aspect can be solved by applying ESV total correction method.
