Balancing Water Supply and Demand in Shenyang Modern Metropolitan Area
摘要
Abstract
In this study,the Shenyang Modern Metropolitan Area was selected for research and we ex-plored the balance between water supply and demand.Natural hydrological processes and water demands for production,living,and consumption were comprehensively analyzed at the prefecture-level scale.The Shenyang Modern Metropolitan Area includes the cities of Shenyang,Anshan,Fushun,Benxi,Fuxin,Li-aoyang and Tieling,and the Shifu demonstration zone.Using a GIS platform,land use data for 2000,2010 and 2020 and other basic data on geography,digital elevation,meteorology,soils and socioeconom-ics were used to simulate and study the water supply service pattern.Effective spatial visualization was achieved by combining the water yield module of the Integrated Valuation of Ecosystem Servic-es and Tradeoffs(InVest)model,the water demand service model and the water security index.Results show that the water supply for the Shenyang Modern Metropolitan Area was 153.36×108 in 2000,447.57×108 in 2010 and 235.86×108 m3 in 2020,and the gap between supply and demand was large.The water resource security index for Shenyang,Anshan,Liaoyang,Tieling and Fuxin Cities in 2000,and Shenyang and Liaoyang Cities in 2010 and 2020 were all lower than 0.5.Supply and demand for water in the study area showed significant spatial mismatches.Tieling City,Fushun City and Benxi City in the east-ern part of the region were the primary supply areas,while demand in Shenyang City and Liaoyang City in the central area exceeded supply.Our research framework and results provide a valuable decision-mak-ing reference for coordinating mismatches between water supply and demand at the metropolitan area scale.关键词
