Abstract：Based on the single space suitability evaluation of the production-living-ecological space on the Yangtze River Economic Belt， the theoretical mechanism and realization approach of optimizing the layout of “production-living-ecological space” and realizing the coordinated development of “production-living-ecological space” are explored in this paper. With the help of Delphi method and GIS spatial analysis method， based on multi-space evaluation and following the most suitable principle and the principle of ecology-living-production priority diminishing， the functional zones of “production-living-ecological space” in the Yangtze River Economic Belt were determined. From the evaluation results of suitable space， the spatial similarity of the suitability distribution of production and living space is strong， and the spatial heterogeneity between ecological space and production and living space is significant. The ecological， production and living space after the election accounted for 45.72%， 46.98% and 7.30% of the total area， respectively. The production space occupies the largest proportion， and presents the spatial distribution characteristic of “more east and less west， center and periphery”. The ecological space is mainly distributed in the area west of the Hu Huanyong Line. The proportion of living space is the smallest. On the whole， it presents the distribution characteristics of “east mi west sparsity， small agglomeration and large dispersion”. From the provincial scale， the production space of Jiangsu， Anhui， Jiangxi， Hubei， Hunan， Chongqing and Guizhou accounts for more than 50% of the total area. The ecological space of Sichuan and Yunnan provinces accounts for more than 70% of the total area. On the other hand，Shanghai is dominated by living space， with prominent dominant space advantages of each province and great development potential of auxiliary space.
