长三角示范区水利建设标准协同路径研究及实践

Study and practice of cooperation path of hydraulic projects construction standards in the Demonstration Area of Green and Integrated Ecological Development of the Yangtze River Delta

长三角生态绿色一体化发展示范区内河湖水系众多,跨越3个地方行政区域的水利工程存在建设主体、建设机制、功能定位、建设标准等差异。为高标准、高水平、高质量建设示范区水利工程,在梳理分析了示范区内水利工程典型类型和既有水利建设标准体系及标准差异基础上,研究并提出了长三角示范区水利建设标准体系框架和协同路径,并以元荡生态岸线修复和功能提升工程为示范开展了实践。结果表明:①示范区内水利工程主要为典型平原河网地区的水利工程,包括泵闸工程、水源工程、河道湖泊及湿地等类型;②除执行国家和行业的水利技术标准外,各地针对本地水利工程特点出台了诸多地方标准或指导性文件,导致水利建设标准差异性较大;③针对多地既有标准、单一地区先进标准、缺失或创新性标准提出的水利建设标准协同主要路径和辅助路径,以及水利技术标准体系框架,可为示范区水利标准协同和工程建设提供基础依据和保障;④以元荡生态岸线修复项目示范实践形成的跨界水体生态修复和功能提升项目一体化实施标准,体现了跨区域协同要求,彰显了示范区一体化生态建设的机制优势。

There are many rivers and lakes in the Demonstration Area of Green and Integrated Ecological Development of the Yangtze River Delta.The construction subject,construction mechanism,functional orientation and construction standards of hydraulic projects are different across the three local administrative regions of Shanghai,Jiangsu and Zhejiang.In order to construct hydraulic projects with high standards,high levels and high quality,based on analyzing the typical types of the existing hydraulic projects,a construction standard system and the differences of standard in the demonstration area,the framework and cooperation path of construction standard system were studied and proposed.The demonstration practice was carried out at the ecological shoreline restoration and function improvement project around the Yuandang Lake.Results showed that:①Projects in the demonstration area were the typical hydraulic projects in plain river network area,mainly including sluices,pump stations,water sources projects,rivers,lakes and wetlands.②In addition to implementing the national and industrial hydraulic technical standards,various localities issued local standards or guiding documents according to the characteristics of local hydraulic projects,resulting in great differences.③The main path and auxiliary cooperation path of hydraulic engineering construction standard were proposed aiming at existing standards in multiple regions,advanced standards in a single region,missing or innovative standards,as well as the framework of hydraulic technical standard system can provide basis and guarantee for hydraulic technical standard coordination and hydraulic project construction in the demonstration area.④The integrated implementation standard of transboundary water ecological restoration and function improvement projects formed by the demonstration practice of the Yuandang Lake project reflected the requirements of cross regional coordination and highlights the mechanism advantages of integrated ecological construction in the demonstration area.
