Abstract:
Water conservation is closely related to ecosystem processes,production and life of human beings.In-depth research of water conservation is of guiding significance for promoting harmonious coexistence between humans and water and is vital to the health of ecosystems and the sustainable development of human society.With the deepening of the research and application of water conservation,its connotation is gradually enriched,and the evaluation methods become more diverse.However,the definition of water conservation in previous studies is vague,and the comprehensive comparative analysis of various evaluation methods is lacking.Therefore,it is urgent to define the connotation of water conservation and analyze the applicability of its various estimation methods.The history of water conservation research is reviewed by literature analysis,which can be divided into four stages:cognition and germination stage,theory development stage,quantitative calculation stage,and comprehensive model evaluation stage.On this basis,the connotation of water conservation is clearly defined from three aspects of definition,water quantity,and function.The existing estimation methods of water conservation are collected and sorted out,and systematic comparative analysis is carried out on the principles,time and space scales,the application scope,and advantages & disadvantages.The possible research direction on water conservation in the future was also put forward.
