Abstract: Ecological land plays essential roles in ensuring urban ecological security and promoting regional sustainable development. Hence, understanding the dynamic and driving forces of urban ecological land use change is of great significance to urban planning and ecological environmental protection. In this study, we proposed an integrated framework to modelling the dynamic and driving forces of urban ecological land use change. The land use matrix, landscape metrics, ecological service value and INVEST model were used to analyze the dynamics of ecological land use in terms of quantity, spatial pattern and ecosystem function respectively. Besides, the binary logistic regression model and gradient analysis approach were employed to modelling the driving forces of urban ecological land use change. Our experiments were conducted in Wuhan City, China. The results of our study demonstrated that between 1990 and 2014, the area of ecological land in Wuhan City lost 239.55  km2, and the quality of habitats also decreased by 24%. On the contrary, the fragmentation of ecological land plaques increased, which leads to the phenomenon of islanding. The results also illustrated that slope, the minimum distance to builtup area, the growth of built up area, GDP, and road density are the main drivers of urban ecological land use change in Wuhan. Consequently, with the continuous growth of Wuhan City, the risk of loss of ecological land, which located outside 3rd ring road of Wuhan, is increasing.
