新时期兰州新区防洪体系建设现状、存在问题及对策研究

Research on Current Situation, Existing Problems and Countermeasures for Construction of Flood Control System in Lanzhou New Area in New Era

摘要:

“十四五”期间兰州新区经济增速领跑国家级新区，自然气候条件变化显著。针对兰州新区防洪体系面临的新形势与挑战，提出防洪体系建设思路与措施。基于对兰州新区经济社会发展、气候变化影响及蓄滞泄平衡关系变化的深入分析，结合现有防洪规划与工程体系建设现状，识别出当前防洪工程存在短板及“四预”智慧管理等方面存在的问题。研究结论表明，应从工程措施与非工程措施两方面着手，通过建设蓄滞洪区、完善雨洪通道、强化监测预警与应急管理，并探索海绵城市等新技术，构建智慧化、一体化的防洪体系，持续提升区域防洪减灾能力，保障经济社会高质量发展。

Abstract:

During the “14th Five-Year Plan” period, the economic growth rate of Lanzhou New Area led that of national-level new areas, and its natural climate conditions changed significantly. Aiming at the new situation and challenges faced by the flood control system in Lanzhou New Area, the ideas and measures for the construction of the flood control system are proposed. Based on an in-depth analysis of the economic and social development of Lanzhou New Area, the impact of climate change, and the changes in the balance relationship of storage, detention and discharge, and combined with the current status of flood control planning and engineering system construction, the shortcomings of current flood control projects and the problems existing in the “Four Preparations” intelligent management and other aspects are identified. The research conclusion shows that the efforts should be made from both engineering measures and non-engineering measures. By building the flood detention and storage areas, improving the rainwater and flood channels, strengthening the monitoring, early warning and emergency management, and exploring the new technologies such as sponge cities, an intelligent and integrated flood control system is built, the regional flood control and disaster reduction capabilities are continuously enhanced, and the high-quality economic and social development is ensured.
