【Abstract】 On the base of analyzing the construction and the effecting factors of water consumption system, the flow chart of water consumption system in Beijing is constructed, and the relationships between each factors can be seen directly. The dynamical factors and restrictions in system are found by analyzing the feedback information. It is a base of studying water consumption system by system dynamics.更多还原
