Based on the analysis of existing concept of water resources carrying capacity (WRCC), “available water supply” was applied to define the conception of WRCC. Furthermore, modifications on research methods on WRCC were mated with analyzing the shortages of current research methods on WRCC. First of all, in order to solve the problems of uncertainty in qualitative assessment of WRCC, an assessment method based on dynamic feedback was suggested to qualitative assessment of WRCC. Secondly, in order to solve the disadvantage of existing quantitative assessment model of WRCC rarely consider the influence of spatial availability of water supply and spatial heterogeneity of water user, a distributed quantitative assessment model of WRCC was established. Contemporary, a calculation unit division method that by means of overlap analysis of DEM, land-use map and water user map was established. Finally, a qualitative and quantitative model of WRCC is established by coupling the qualitative assessment method based on dynamic feedback and distributed quantitative assessment model.
