- Abstract:
- Taking the improvement of the Swan Lake water system in Qilin Mountain, Shenzhen as an example, the engineering measures as well as the management and control measures are introduced. The engineering measures mainly include double water sources supplementation, hydrodynamic condition improvements, ecological wetlands construction, aquatic plants transformation, and aquatic ecosystem restoration. The management measures mainly include seasonal differential operation and normal operation of water ecosystem. After remediation, the water quality and sensory condition of Swan Lake have been significantly improved. The content of chlorophyll a has dropped by over 90%, and the transparency has increased from a minimum of about 20 cm to over 100 cm, which could provide a reference for subsequent related similar projects.
