闽江沙溪流域构建安全生态水系的探索

On Construction of Safe Ecological Water System in Shaxi Watershed of Minjiang River

传统的工程水利、资源水利发展未能把流域作为完整单元进行统一规划、系统治理,导致河道与水工程几何化、硬化、沟渠化、湖库化等问题突出。闽江沙溪流域从“整合旧规范、探索新方法;改造小水电、确保常流水;改造硬工程、实现人水和;连通河与湖、提高承载力;保护原生态、传承水文化”五个方面构建安全生态水系,实现“河畅、水清、岸绿、景美、安全、生态”六大建设总目标。

The traditional concepts of engineering-based water conservancy and resource-based water conservancy failed to take the basin as a complete unit for unified planning and systematic governance.As a result,the problems of river course are prominent,which were shaped into geometric way as ditches,lakesand reservoirs.The construction of safe ecological water system in Shaxi watershed is introduced from five aspects as“integrating old norms and exploring new methods,transforming small hydropower and ensuring perennial drainage,transforming defective projects and realizing mutual harmony,connecting rivers and lakes and improving carrying capacity,protecting original ecology and inheriting water culture”,so as to realize the six major construction objectives as“smooth river,clear water,green shore,beautiful scenery,safety and ecology”.
