基于量质耦合的中原城市群水资源利用效用评价研究

Production and evolution of regional water resources utility is impacted by both of water quantity and water quality. Evaluation of water resources utility based on the coupling of water quantity and water quality is the key to water ecology construction and efficient utilization of water resources. Takes the Central Henan Urban Agglomeration as the case study area, this research analyze the dynamic evolution process of water quantity, water quality and economy, determine the efficiency and benefit of water resources utilization based on the coupling of water quantity and water quality and dissects their spatial distribution. A water resources-environment-society based water quantity- quality balance model will be developed to find out the roles of economic, water use consumption, industrial distribution and water price play in pushing forward the revolution of water resources utility, identify the key factors and their thresholds and judge the variation trend with an attempt to evaluate the water resources utility. The CGE model of Central Henan Urban Agglomeration will be built to allocate water resource based on optimal effectiveness and finally to realize the quantity-quality-effectiveness associative process. Additionally, suggestions to improve water use effectiveness based on the simulation results will be discussed, which will provide theoretical support to water management for Central Henan Urban Agglomeration.
