Assessment of water resource carrying capacity of Jiangsu province

Theory analysis is made about the feasibility of using system dynamics method for water resources carrying capacity evaluating in the paper first.Then the concept of deficiency coefficient of water supply and water demand is put forward for water resource carrying capacity evaluation.Based on the water resource characteristic of Jiangsu province,water resources carrying capacity is studied with the method of system dynamics.Eight typical models of Jiangsu water resources carrying capacity are formulated by calculating the economic growth rate,the water supply planning and the different guarantee rate,which are helpful for Jiangsu water resources carrying capacity building.
