Abstract: Understanding land use transformation and its ecological effects based on “ecological-production-living” functions is an important issue of land use/land cover change, which can provide support for the optimization of “ecological-production-living” land use. We constructed a classification system of “ecological-production-living” land use mainly oriented by dominant functions of land use for Yingkou City. A modified quantitative and spatial analysis model was used to analyze the dynamics and regional types of “ecological-production-living” land use transformation, and adopted the improved equivalent factor method to analyze the profit and loss of ecological service value. The results showed that, during 2000-2015, the transferred area of ecological land was the largest, with the active types of ecological land being distributed in the southwest and central north of the city. The living land significantly increased with a high speed, being mainly transformed from ecological land and agricultural producing land. The total value of ecological service in Yingkou experienced a decreasing-increasing-decreasing process, and was higher in the southeast and lower in the west. The change of ecological service value presented a spatial pattern of “three regions”. During 2000-2005 and 2010-2015, the decreasing trend in southeastern and north central area was significant, consistent with the spatial distribution of newly added active type of living land.
