中文摘要:
      都市圈、城市群等区域尺度水资源供给服务的供需定量评估与空间可视化是当前生态系统服务研究中的重要议题。本文以沈阳现代化都市圈为研究区,基于GIS平台,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,目的是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。研究结果表明: 1)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;2)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;3)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。本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。
英文摘要:
      The quantitative evaluation of supply and demand and spatial visualization of water resources supply services in metropolitan area, urban agglomerations and other regional scales are important topics in the current research of ecosystem services. Taking Shenyang modern metropolitan area as the research area, this article simulated and studied the water supply service pattern in a spatial visual way based on GIS platform, coupled with water production module of InVest model, water demand service model, water resources security index and other methods. The purpose is to reveal the balance between supply and demand of regional water supply services and provide basis for the optimal management of regional water resources. The results show ed that: 1) from 2000 to 2020, the water supply and demand of Shenyang modern metropolitan area showed a trend of first increasing and then decreasing, and the gap between supply and demand balance was large; 2) the water resources security index of Shenyang, Anshan, Liaoyang, Tieling and Fuxin in 2000 and that of Shenyang and Liaoyang in 2010 and 2020 were lower than 0.5; 3) the spatial distribution of supply and demand of water supply services in the study area showed significant mismatch characteristics. Tieling City, Fushun City and Benxi City in the east of the region are the main supply areas, while the demand of Shenyang City and Liaoyang City in the middle was greater than the supply, and the contradiction between supply and demand of water resources was prominent. The research framework and results can provide certain decision-making basis for coordinating the contradiction between supply and demand of water resources in urban agglomerations.
