江苏省秦淮河防洪治理工程力争2029年主体工程完工，目标：中心城区流域防洪标准达200年一遇

Core Viewpoint - The Jiangsu Qinhuai River Flood Control Project is a significant infrastructure initiative aimed at enhancing flood management capabilities in the Qinhuai River basin, addressing historical flooding issues and improving water resource allocation and ecological protection in the region [3][4][9]. Construction Background - The Qinhuai River, a tributary of the Yangtze River, has a total watershed area of 3,103 square kilometers and a length of 175.4 kilometers. The river has historically faced severe flooding due to its downstream outlet being constrained by the Yangtze River's high tide levels, with flood discharge capacity currently falling short by 300 cubic meters per second compared to planning requirements [3][4][9]. Project Significance - This project is included in the Ministry of Water Resources' flood control plans and is crucial for improving the flood disaster reduction system in the Qinhuai River basin, optimizing water resource distribution, and supporting the economic and social development of Nanjing and surrounding areas [4][9][10]. Overall Layout - The Qinhuai East River project features a "2+1+2" layout, comprising the upstream Yunliang River, central river, midstream Xinkai River, and downstream Jiuxiang and Qixiang Rivers, with a total length of approximately 53 kilometers [5][9]. Construction Details and Investment - The first phase of the project involves the renovation of 15.96 kilometers of river channels, with a total estimated investment of 630.884 million yuan (approximately 63.09 billion yuan). Key components include the construction of a new dam and the reinforcement of 19 bridges affected by the river channel renovations [6][10]. Future Work Focus - The project will prioritize three areas: advancing construction for the 2025 early start node, progressing research and design work, and coordinating land approvals and archaeological investigations to ensure timely project execution [11].
