摘　　要：针对河道水资源严重污染、水生物数量减少、河道严重阻塞等问题,基于"海绵城市"建设设计理念,对河道水资源治理的关键技术进行了研究。通过底质改良技术、微生物系统构建、沉水及挺水植被系统构建、水生动物系统构建等水生态系统的修复以及生态岸线的构建,确保水体水质主要指标在非雨季达地表水Ⅳ类标准,恢复河道自净能力,提高水体透明度,改善河道水质,形成岸上到岸下多层次景观。通过设计、施工与养护等措施,模拟出适合生物生长的环境,重新构建河道生态环境,使得城市河道形成一个更为完善的整体。In view of the serious pollution of river water resources,the reduction of aquatic organisms and the serious blockage of river,based on the construction and design concept of"sponge city",the key technologies of river water resources management are studied.Through the improvement technology of sediment,the construction of microorganism system,the construction of submerged and emergent vegetation system,the construction of aquatic animal system and the construction of ecological shoreline,the main indicators of water quality are ensured to reach the class IV standard of surface water in non-rainy season,so as to restore the self-purification capacity of the river,improve the transparency of the water body,improve the water quality of the river,and form a multi-level landscape from shore to shore.Through the design,construction and maintenance measures,the environment suitable for biological growth is simulated,and the river ecological environment is reconstructed to make the urban river form a more perfect whole.
