Aiming at the problems in implementation of water resources constraint,the concept of"water dominates development"is interpreted under principle of scale control and coordination.By identifying the internal relationship between water and the four aspects of"human,industry,land,and urban",the control indicators and coordination optimization criteria for"Water dominates development"are proposed as"Four Determinations".An analytical approach is proposed including indicator identification analysis,coordinated optimization calculation,development quality evaluation,and control measures.The coordination optimization criteria and constraint rela-tionships for"Four Determinations"are clarified based on the principles of"respecting the status quo,ensuring basic needs,efficiency-driving,and regional balance".A multi-objective optimization model is established to drive efficiency and achieve regional balance,with constraints of water availability and allocation relationships.The model selects the maximum per capita GDP as the economic goal to achieve efficiency driven principles,so that limited water supply can support greater output benefits.The other objective is degree of matching between population and industrial distribution as the social goal,so that regional economic development differences can be narrowed to ensure the development fairness.By setting constraints to ensure the rigid demand for strategic develop-ment,controlling the reasonable range of regional water allocation and economic growth,the overall results of in-dustrial development coordination and water optimization allocation are obtained.In response to the"Four Determi-nations"plan,evaluation indicators are selected from four aspects:development level,coordination,efficiency,and ecology.An evaluation indicator system and evaluation method are constructed to adapt to high-quality devel-opment goals,and control measures that can implement the"Water dominates development"control direction are proposed.
