In order to find out the water quality of Zaozhadian lake in winter and provide a theoretical basis for the popularization of constructed wetlands in northern China, the spatial characteristics of phosphorus in water quality at the entrance of Zaozhadian Lake in winter were revealed through field sampling and the study of phosphorus release characteristics of Zaozhadian Lake in winter. The results show that the contents of total phosphorus and total nitrogen in the five water quality indicators are lower than the national surface water V standard, so the area is heavily polluted. The water quality of the natural ecological area is better than that of other lake areas, and the wetland may have some self-purification capacity in winter.The contents of total phosphorus and soluble orthophosphate in lotus root area and reed area are significantly lower than those in the area affected by human activities. The content of TP released to overlying water is culture area > enter small wetland > reed area > natural wetland area, and the release quantity reaches the maximum at about 15 days, and the phosphorus content tends to be stable after decreasing.
