Under the background of urban expansion, due to the multi-functional and limited land resources, there are layout conflicts among three types of urban functional space: urban construction space (SUC), grain production space (SGP) and ecological protection space (SEP). Taking Xuzhou City as an example, this paper identifies the characteristics of space conflicts, extracts the urban moderate boundary(UMB) based on the principle of value equilibrium, and uses it as the space boundary to solve the conflicts. The results show that: (1) The space conflicts can be divided into three types: construction-production conflicts, construction-ecological conflicts and production-ecological conflicts, with an area of 17.31 km2, 14.13km2 and 3.24 km2 of each conflicting area respectively. (2) The cultivated land value (also the construction land price) corresponding to the UMB is 941.90 yuan / km2. The construction-production conflicts and construction-ecological conflicts within the UMB should be reserved as SUC, those outer part of the boundary should be reserved as SGP and SEP. The production-ecological conflicts should be reserved as SEP according to the principle of ecological priority. (3) After solving the conflicts, the scale of SUC, SGP and SEP are 240.18 km2, 42.56 km2 and 55.35 km2 respectively. The new perspective and method proposed in this paper can provide reference for urban planning and urban functional space layout optimization.
