"四水四定"和谐共生的理论体系及应用途径OA

The"defining the scales based on water"harmonious coexistence is an emerging water-resources management concept,emphasizes the thorough implementation of the"defining the scales based on water"princi-ples and the concept of"harmonious coexistence"with the rigid constraints of water resources.The concept′s back-ground was systematically analyzed,and based on clarifying the principles of"defining the scales based on water"and the concept of"harmonious coexistence",its definition was established.The deeper connotation was examined from the perspective of interactions between human systems and water systems.The concept was based on three fun-damental principles:the regional water balance principle,human-nature symbiotic co-prosperity principle,and hu-man-water relationship harmonious evolution principle.Its main methodological approach included system identifi-cation,simulation analysis,metric evaluation,and optimization control.The core concepts were articulated across five dimensions:coordinated development,dynamic regulation,system-level synergy,supply-demand balance,and water-adapted development.Based on these elements,a theoretical framework for the concept of harmonious coexis-tence of"defining the scales based on water"was established,and its theoretical foundations were systematically elaborated.Furthermore,the concept′s application pathways and prospects were explored from multiple dimen-sions,including planning,policy,management,strategy,technology and discipline.The study provided a theore-tical basis and practical reference for the refined management of water resources and the coordinated development of multiple systems.
