- The Middle Route of China's South-to-North Water Diversion Project is crucial for providing drinking water to North China, but there's insufficient understanding of hydrodynamics, water quality, and ecological interactions in its early operational phase.
- This study analyzes the ecological changes in the main canal's environment, specifically looking at factors impacting algae growth, using principal component analysis to assess water quality and algae distribution.
- Findings reveal that water quality varies along the canal, with COD and algal density increasing from south to north, while dissolved oxygen decreases; algal density is highest in summer and lowest in winter, with different water flow conditions affecting algae distribution.
