Abstract: Understanding the changing laws of urban space production, life and ecological functions under the background of rapid urbanization is not only an important part of human-economic geography research, but also an intrinsic basis for urban land space development and its pattern optimization. This paper takes Changsha Metropolitan Area as the empirical area, takes remote sensing image and urban land use survey data as the main data sources, selects 2000, 2009 and 2016 as the research time nodes, and builds the “production-living-ecological” function evaluation system based on the differences of land main functions. Using spatial autocorrelation, cold hot spot analysis and sample band analysis, the characteristics of Changsha’s “production-living-ecological” function are explored and the regulatory path is proposed. The results show that: (1) The overall production and living functions of the Changsha metropolitan area continue to strengthen, but the ecological function has been weakened; (2) The strength of the “production-living-ecological” function within the Changsha metropolitan area has also changed, and the functional space has been reorganized. The balance of functions of students is improved; (3) The comprehensive function level of “production-living-ecological” in Changsha urban area continues to improve, and high-level areas gradually gather in urban centers, showing single-core agglomeration→single-core agglomeration-multi-core dispersion→network equalization Functional space structure development model, but the “production-living-ecological” functional space unit change mode is different; (4) The spatial pattern of the Changsha metropolitan area should be comprehensively regulated from the aspects of “uality” and “quantity” of the “production-living-ecological” functional land use structure.
