Research on the influencing factors of improving the water quality of Dawangtan Reservoir
This paper introduces the changes in the water quality of Dawangtan Reservoir since 2021 and analyzes the changes in water quality.The results show that the water quality of Dawangtan Reservoir has tended to stabilize overall,with the water quality reaching the Class Ⅲ standard of surface environmental quality standards.Some indicators,such as dissolved oxygen,ammonia nitrogen,and total nitrogen,have shown slight improvement.The monthly average concentration of ammonia nitrogen is consistent with the fertilization pattern of eucalyptus trees planted around the reservoir,while the levels of permanganate index and total phosphorus are consistent with the distance and scale of residential areas,mainly affected by human production and life activities.Although the water quality of the reservoir has not exceeded the standard,the level of total nitrogen is still high,and controlling the input of nitrogen from the upstream of the reservoir is necessary to maintain stable and standard water quality.
