Theoretical framework of limit regulation of water supply and consumption system based on controllable damage
As an extreme climate phenomenon,severe drought can lead to serious water resource shortages,eco-logical damage,and socio-economic losses.In order to combat drought and reduce disasters,the water supply side should tap into its potential and increase supply as much as possible,while the water consumption side should be compressed and controlled as much as possible,that is,the extreme regulation of the water supply and water consumption systems.However,the implementation of extreme control measures will inevitably cause damage to the water supply and consumption systems themselves,such as excessive development of water sources,deteriora-tion in water quality,and loss of water supply facilities.In order to ensure the sustainability of water supply and consumption systems,the regulation of water supply and consumption systems under extreme drought conditions must challenge limits while ensuring controllable damage.Therefore,the theory of limit regulation of water supply and consumption systems based on controllable damage is the foundation of scientific drought resistance and disaster reduction under extreme drought conditions.This article introduces the theory of dissipative structure,analyzes the characteristics of water supply systems under extreme drought conditions,and deeply explores the concept and con-notation of controllable damage.Based on this,a theoretical framework for the ultimate regulation of water supply systems under extreme drought conditions is proposed,providing theoretical guidance and methodological support for the regulation of water supply systems under extreme drought conditions.
