Abstract

Will the world run out of clean water According to the United Nations, one quarter of the world's population experience water scarcity. We construct three models to solve the world’s water problems. We establish models for the ability of a region to provide clean water. We apply the SD model to solve the problem. The model is dynamic and it contains the concept of feedback, including a feedback loop and the feedback system. We consider four subsystems, including water resources subsystem, social subsystem, economic subsystem and ecological environment subsystem. For an unknown quantity column in the four subsystems, we write equations, and then make water resources carrying capacity system structure of SD general layout. We give an analysis of the cause’s tree. Determine appraisal index water resources carrying rate I. When I > 1, that is beyond the carrying capacity of water resources. When 0 < I < 1, it is in the water resources carrying capacity of critical state. The model test is divided into two parts, dimensional consistency and check consistency.
