Wuhan Metropolitan Area is one of the earliest comprehensive reform pilot area of resource-saving and environment-friendly society construction. It is also key areas of the Central China Development Strategy and the Yangtze River Economic Belt. Scientifically understanding temporal characteristics of land use change of Wuhan Metropolitan Area is of great significance for formulation and implementation of regional land use policy. Based on the land use data in 2000, 2005, 2010 and 2015 of Wuhan Metropolitan Area combined with GIS spatial analysis, mathematical statistics, single land use dynamic degree, transfer matrix and integrated land use dynamic degree methods of land use, we studied the general characteristics of land use change, the direction of change and regional differences in characteristics of Wuhan Metropolitan Area during 2000 to 2015, and analyzed the policy-driven factors of land use change. The results showed that: (1) for the general characteristics, during 2000 to 2015, cultivated land, woodland, grassland and unused land was diminishing while residential land and water area was increasing. (2) For the changes in direction, during 2000 to 2015, cultivated land and forest land transformed to residential land and water was the main feature. During 2000 to 2005, farmland and residential land transformed to water was the main feature. During 2005 to 2010, cultivated land transformed to residential land, water and forest land transformed to residential land were the main feature. During 2010 to 2015, cultivated land, woodland, grassland and water transformed to residential land was the main feature. (3) For spatial and temporal differences at regional scale, the largest dynamic degree of integrated land use concentrated in the central area of Wuhan Metropolitan Area. From the aspect of dynamics degree of single land use, cultivated land was concentrated in surrounding areas of Wuhan Metropolitan Area. Residential land was mainly located in central region of Wuhan Metropolitan Area. Water was concentrated in Xiantao City of Wuhan Metropolitan Area. Woodland was mainly located in Qianjiang city, Yunmeng County. The grass was mainly located in Yingshan County. (4) For the analysis of policy-driven factors, reforestation, urbanization, the rise of the Central Plains, two-oriented society, the development strategy of Yangtze River economic belt and other policies have important implications on land use change.
