Research on optimization of rural settlement patterns has practical significance for intensive use of rural land resources and reshaping rural landscape. We selected Hebao Town, Rongchang District, Chongqing municipality as a case study. This town is located in typical hilly area. The ‘symbiotic patch’ of merged rural residential land was chosen as a unit for analysis. Based on the principle of coordinating production, living and ecology spaces (called as the three spaces hereafter), the strategies and directions of optimization of rural settlement patterns were investigated. The results indicated that:(1) the research unit of ‘symbiotic patches’ of rural residential land was appropriate because it took symbiotic relationship into account regarding the real situation of hilly areas; after rural residential patches within 50 meters buffer were merged into big ones, the number of patches decreased from 2 584 to 1 047, which showed that rural residential patches with symbiotic relationship came into integration; (2) in terms of the coordination concept of the three spaces, the grades of ‘symbiotic patches’ of rural residential land were also evaluated, the spatial pattern of grading map showed a gradient change from inside to outside; according to patch level, patch scale, coordination degree of the three spaces and town planning, different strategies of optimization of rural residential patches were proposed, which included urbanization, main construction, scale control and migration merge; (3) the weighted Voronoi diagram was generated by large settlement patches in the type of main construction, which would be reasonable to guide the pattern of rural settlements based on the diagram. In summary, this study suggested that combination of coordination concept of the three spaces and spatial analysis tools was workable because the combination was helpful to optimize the pattern of rural settlement patterns, maintain the stability of overall spatial pattern, and promote rural transformation and preservation of local culture.
