| 以沈阳现代化都市圈为研究区，从地级市尺度上综合自然水文过程和居民生产、生活消费需求，揭示区域水供给服务供需平衡关系，为区域水资源优化管理提供依据。基于GIS平台，采用2000、2010和2020年土地利用数据，耦合InVest模型产水量模块、水需求服务模型、水资源安全指数等多种方法，以空间可视化的方式模拟研究水供给服务格局。研究结果表明：2000―2020年沈阳现代化都市圈水供给量和水需求量均呈现先增多后减少的趋势，供需平衡状况差距较大；2000年沈阳市、鞍山市、辽阳市、铁岭市、阜新市的水资源安全指数以及2010年、2020年沈阳市、辽阳市水资源安全指数均低于0.5；研究区水供给服务的供给与需求在空间分布上呈现显著的不匹配特征，区域东部铁岭市、抚顺市、本溪市为主要供给区，中部沈阳市、辽阳市需大于供，水资源供需矛盾突出。研究框架思路与研究结果能够为都市圈尺度水资源协调供需矛盾提供一定的决策依据。 |

| In this study, the Shenyang Modern Metropolitan Area was selected for research and we explored 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, Liaoyang 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 socioeconomics 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?Services?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 eastern 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-making reference for coordinating mismatches between water supply and demand at the metropolitan area scale. |
