摘要：Water resources carrying capacity is a foundational topic in water resources security strategic stu...Water resources carrying capacity is a foundational topic in water resources security strategic study and the foundational measurement of water resources security. Water resources constrain the scale and quality of social and economic development in many water shortage cities and regions. Thus, the management via dynamic water resources prediction is a key for the overall city strategic planning. In this study, an integrated dynamic model of water consumption was developed using system dynamics (SD) and based on water resources carrying capacity (WRCC) theory.显示全部
