However, there is a lack of synthesized knowledge about the contributions and profitability on socio-economic aspects of the cryospheric services (CSs). To cope with this key and urgent sustainable development issues, this study constructs a comprehensive regionalization research system that integrates the natural and socio-economic aspects for cryospheric characteristics with emphasis on interdisciplinary approaches. Guided by the supply- demand equilibrium model and the service maximization model, the research system consists of establishing a classification system for CSs, identifying the spatial distribution pattern of CSs, and constructing the comprehensive regionalization of CSs, which finally divides the research area into relatively independent, complete, and organically linked CS units of multiple spatial levels. By setting up a bridge between the CSs with socio-economic needs, it has profound and practical significance and implications for implementing the sustainable utilization strategies and macroeconomic policymaking for global environmental protection.展开更多

Under the current conditions, the water supply quantity of emergency water sources and the total emergency water supply quantity will meet the emergency water demand with the guarantee rate of 65.79% to 377.78% and 90.35% to 270.51% respectively. By 2020, the water supply quantity of emergency water source places and the total emergency water supply quantity will meet the emergency water demand with the guarantee rate of 22.08% to 74.49% and 82.65% to 144.08% in the benefited areas of South-to-North water diversion(SNWDP); and for non-SNWDP areas, the guarantee rate will be 74.64% to 337.78% and 74.64% to 377.78%.展开更多
