梯级河湖水系水环境治理综合技术研究与实践

Research and Practice of Comprehensive Technology for Improvement of Cascade Water System

红岩水库、盘溪河位于重庆主城区,为典型的梯级河湖水系,其水体呈严重富营养化。目前对单个水体的水环境保护技术研究较多,而对以河湖水系为整治对象的研究不足,水系水环境综合整治相互协调不够。针对该水系水环境现状及整治的紧迫性,提出采取河湖协同治理、污染控制与生态修复相结合、自然补水与人工循环相结合、功能性与景观亲水性相结合等治理理念,并针对水系的各个水体提出相应的技术措施,以期为我国同类型的水系水环境整治提供借鉴。

Cascade water system composed of Hongyan Reservoir and Panxi River is located in the main urban area of Chongqing. The phenomenon of water eutrophication of this water system is serious. Presently, there are many water environment protection technology researches on single water body, but researches on water system composed of rivers and lakes are relatively inadequate, and the mutual coordi- nation of comprehensive improvement of water environment is also not enough. Based on the water envi- ronmental status and the remediation urgency of this water system, some restoration measures are pro- posed, such as cooperative improvement of rivers and lakes, combination of pollution control with ecologi- cal restoration, integration of natural and artificial replenishment water, and fusion of functionality and accessibility of waterfront. Meanwhile some corresponding technical measures of each part of water system are also proposed in order to provide a reference for similar water environment improvement projects.
