Analysis on regional differences of water use efficiency rigid constraints and countermeasures in Zhejiang Province

Abstract

With the implementation of the most stringent water resources management system, rigid constraints on water resources have gradually increased, the total amount of water used has been effectively controlled. In order to quantify the strength of rigid constraints on water resources, the concept of rigid constraints on water efficiency was proposed, and the constraints on industrial and agricultural water efficiency targets and regional differences in 11 districted cities in Zhejiang Province were analyzed, and the target constraints in the industrial and agricultural water use were comprehensively considered through scenario analysis. Seven types of areas, including industrial and agricultural strong control, agricultural main control, and industrial main control are drawn, and countermeasures for optimizing water resources and water-saving management for different types of areas are put forward to further improve the level of water resources management in Zhejiang Province.
