Division of China Water Conservancy Development Stages:Theoretical Framework and Evaluation
Water conservancy plays a greater role in China' s sustainable development.A thorough analysis of China' s evolvement of national condition and water regime,together with a reasonable division of water conservancy development stages keeps us well informed about the reference value to the strategic choice of water conservancy development.The theory and methodology of the division of water conservancy development stages is a relatively new subject in academic research.This paper puts forward a set of theoretical framework based on a comprehensive understanding of interactive relationship between the water conservancy development and eco-environment-socio-economic system,analyzes its supply-demand' s evolution tendency,and then evaluates the stage features of water conservancy development.Based on this,it puts forward the methodology of stage division of water conservancy development:investigate the supply and demand of water conservancy development evolution,integrating with the ecological environment changing trend and selecting some representative years as the node,to get the division of water conservancy development stages judged by quantitative index analysis and empirical analysis.According to the above theory and method,this paper divides China' s centennial water conservancy development (1949-2050) into seven main phases.
