Rural multifunctional values?in urban fringes are prominent at the current stage of urbanization in China. Therefore, it is urgent to delineate "production-living-ecological" space using the rural multifunction theory in order to carry out spatial reconstruction. This study developed a comprehensive method for delineating the "production-living-ecological" space in urban fringe based on rural multifunction evaluation, taking Tongshan District of Xuzhou City for empirical research. First, the spatial and temporal changes of rural multifunctions were evaluated from the aspects of production, living, and ecological functions. Second, suitability evaluation for "production-living-ecological" space was carried out at the grid scale, and then, the rural multifunctional "production-living-ecological" space suitability evaluation result was attained. Finally, the "production-living-ecological" space was delineated. The study revealed that: 1) With the overwhelming development of rural recreation and sightseeing agriculture in urban fringe, the application of rural multifunction theory to the reconstruction of multifunctional space can promote development transition. 2) Non-agricultural production function and living function are mainly distributed in the suburbs surrounding the main urban area, while agricultural production function is mainly distributed in the outer suburbs, and ecological function shows clear spatial heterogeneity. Agricultural, non-agricultural production, and living functions are improving, while ecological function is declining. 3) "Production-living-ecological" space delineation at county level needs multiscale combination, not only considering the multifunctional differences at the township scale, but also accounting for suitability at the vector or grid level. The proposed method of delineating "production-living-ecological" space based on rural multifunctional evaluation can provide a scientific basis for spatial planning.
