Abstract:
The Baishi reservoir is an important water supply reservoir in the west of Liaoning Province, therefore an objective e 2 valuation of water quality contributes to the protection of water resource and provides the basis for scientific management of res2 ervoir. In this paper, the physical and chemical tendency analysis of the total nitrogen, ammonia nitrogen, dissolved oxygen and permanganate index was conducted based on water samples in the front dam of Baishi reservoir using the seasonal Kendall test method. The results showed that the total nitrogen in the Baishi reservoir exceeds the standard and has a deteriorative trend, so the management of water quality in the Baishi reservoir needs to be further strengthened.
