Abstract:Focusing on the new requirements of national water network construction in the new era, the foundation, situation and weak links of modern water network construction in Changfeng County of Hefei are analyzed from the aspects of flood control safety, water resource guarantee, water ecological restoration and smart water management. The overall layout of Changfeng water network with the “two-channel four-water outline, two-line seven-river goal, and ten-gate (station) and 100-reservoir structure” is proposed, and the task of water network construction with the “two-lake two-river security, three-river mutual relief as the source, dual-channel multi-corridor water protection, and digital empowerment to improve efficiency” is put forward, which can provide some reference and inspiration for the construction of county-level water networks in other regions.
