基于生态系统服务流的东北地区水安全格局OA北大核心CSTPCDEI
Water security pattern in Northeast China based on ecosystem service flow
基于供水服务"供-流-需"(供给-流动-需求)的研究思路构建水安全框架,采用水生态系统服务供需比测度水生态系统供需服务盈余和赤字状态,提取水生态"源""汇"区,采用最小累计阻力模型识别"源-汇"廊道和脆弱节点,进而分析东北地区水安全格局.结果表明:2000-2020年东北地区产水量和需水量均呈增加态势,空间上产水量大致呈东多西少分布,需水量的空间分布与人口密度、社会经济发展程度高度一致;整体而言,研究期内水生态系统供需服务主要表现为盈余状态,且盈…查看全部>>
A water security framework was constructed based on the research idea of"supply-flow-demand"of water supply service.The surplus and deficit states of water ecosystem services were measured with the supply-demand ratio of water ecosystem services,and water ecological"source"and"sink"areas were extracted.The minimum cumulative resistance model was used to identify"source-sink"corridors and vulnerable nodes,and the water security pattern of Northeast China was …查看全部>>
