Regional ecological land has changed dramatically with the rapid development of industrialization and urbanization. It is essential to study and predict the changes of ecological land and the corresponding ecosystem service value on a small scale in order to provide reference for ecological land protection and land use planning. Taking Guanlin Town in Yixing City as the study area, the ecological land changes from 2009 to 2015 were studied based on high resolution remote sensing image, the influential factors were analyzed by Logistic Regression model, the changes of ecological land in 2021 and 2024 were simulated using CA-Markov model, then the corresponding ecosystem service values were calculated. The results were as follow: 1) Ecological land in Guanlin town decreased from 2009 to 2015, and the main influential factors were elevation, GDP, population density and the distance to river. The influences of natural factors on the changes of ecological land type were gradually weakened with time, while the roles of socio-economic and location factors were gradually intensified. 2)Ecological lands would decrease rapidly from 2015 to 2024, in which paddy field decreased mostly, decreased by 358.25 hm², while aquaculture water increased rapidly, with an annual increase of 24.23 hm², totally increased by 16.97%. Ecological lands mainly were transferred to aquaculture water, dryland, industrial land and traffic land. 3)The corresponding ecosystem service values decreased continuously from 2009 to 2024, significantly correlated with the changes of farmland and water body. The above results can provide reference for land use planning in Guanlin Town and has practical significance in protecting ecological land and in strengthening the ecosystem service as well.
