[Objective] To regionalize the ecological functional zoning and coordinate the contradiction between economic development and ecological protection in order to realize the regionalization management of ecological environment.[Methods] Fushun City was taken as the research area, a regional aquaculture sensitivity assessment system was introduced into traditional evaluation indicators according to its actual ecological environment characteristics, and ArcGIS 10.1 software was used, to evaluate the ecological environment sensitivity and ecological service function of water source, soil and biology in Fushun City. Then, the method of geographical correlation was used to regionalize the ecological function zoning, to compare the service function difference of functional areas, and to set up the partition management plan.[Results] According to the analysis, the sensitivity of the study area was mainly mild and insensitive, showing a "claw" pattern. The extremely and highly sensitive areas were mainly the Laohutai and Longfeng mining areas, and the steep slopes (approximately 1.08% in total). The distribution of the importance of ecosystem service was similar to the topography distribution. The major ecosystem of the most important areas was forests in the southeastern part of the country (about 79.46%).[Conclusion] Fushun City belongs to normal temperate and theropencedrymion ecological areas and is divided into two ecological function sub-areas and eight ecological function areas. According to the functional differences, it can be divided into ecological conservation zone, ecological restoration zone and ecological prohibited zone.
