Abstract: ：Quantitative identifications of functional urban built-up land dynamic characteristics and patterns are the important foundation to promote the national strategies, which including the sustainable urban built-up land use and facilitating neo-urbanization and initiatives. . This study developed an index system and corresponding models for estimating urban built-up land function from three aspects, namely population capacity, production and consumptions, and public services. In this paper the functional evolution and pattern of urban construction land are explored in central China（Hubei, Hunan and Jiangxi provinces) at multi - scale during the period from 2000 to 2014. The results are as follows:（1) the trend of the population capacity, production and consumptions, and the integrated function of cities located in Hubei, Hunan and Jiangxi provinces showing a growing trend, and the temporal processes were relatively complex（2) varied dynamic characteristics of urban built-up land functional changes were observed in districts at different scales, especially in metropolitan areas. Specifically, cities located in areas along the Yangtze River and metropolitan regions generated high values of development index of urban built-up land, and spatial heterogeneity is strong in metropolises;（3) it was dominated by the mixed evolution pattern for the dynamic functional urban built-up land which made the landscape of urban built-up land functional conversions much more complex. In addition, the large types of dynamic urban built-up land function in population containing were gained with significant trend dominated by decreasing patterns. It was discovered that relatively ordinary dynamic of urban built-up land function in production and consumptions, public services and comprehensive function which were contiguous in space. Significant increasing improved dynamic mode in comprehensive urban built-up land function was also discovered particularly in Wuhan. Studies on the mechanisms of dynamic patterns of urban built-up land function and the sustainable multi-level urban land management strategies are desired for approaching ne-urbanization and beautiful China.
