黄河流域城市菏泽湿地资源丰富,因黄河多次泛滥,导致菏泽地区河湖水网淤塞,水系紊乱。菏泽市水利工程规划设计强化空间干预,现状的主要水系均为人工开挖的河道,河道建设以洪涝灾害防控为导向,以快排为目的,规划后的河道布局干流化明显,...黄河流域城市菏泽湿地资源丰富,因黄河多次泛滥,导致菏泽地区河湖水网淤塞,水系紊乱。菏泽市水利工程规划设计强化空间干预,现状的主要水系均为人工开挖的河道,河道建设以洪涝灾害防控为导向,以快排为目的,规划后的河道布局干流化明显,没有调蓄和生态功能,没有形成具有水生态功能韧性的系统。基于水生态基础设施理念,提出利用丰富的自然湿地和人工湿地资源,开挖人工河道,规划建设与城市发展相匹配的区域水系,提高水网密度,增加调蓄空间,降低洪涝风险,构建以河流和湿地为骨架的区域水生态基础设施,增强区域水生态韧性。The city of Heze in the Yellow River Basin boasts abundant wetland resources. However, repeated flooding of the Yellow River has led to the silting of rivers and lakes in the Heze area, causing disarray in the water system. The water conservancy project planning and design in Heze have emphasized spatial intervention, resulting in the main waterways being artificially excavated channels. These channels have been constructed with a focus on flood and waterlogging disaster prevention, aiming for rapid drainage. Consequently, the planned layout of the channels has become noticeably streamlined, lacking in both regulatory storage and ecological functions and failing to form a system resilient in aquatic ecology. Drawing on the concept of water ecological infrastructure, there’s a proposal to utilize the rich natural and constructed wetland resources to excavate artificial channels. The plan involves constructing a regional water system that aligns with urban development, increasing the density of the water network, adding regulatory storage space, reducing flood and waterlogging risks, and building a regional water ecological infrastructure based on rivers and wetlands, thereby enhancing the region’s resilience in water ecology.展开更多
