Abstract:This research established imitative model with system dynamic method for the analysis of the characteristics of water-land resources carrying capacity and the relations among of population, resources , environment and development in Minqin county. Supported by the model, the authors simulated the change trends of water-land resources carrying capacity during 2005 -2025 on different system states and put forward several proposals and countermeasures for enhancing water-land resources carrying ca- pacity in Minqin county based on the simulation results.
Keywords:system dynamics  water-land resources carrying capacity  Minqin County
