Study on the Temporal and Spatial Variation of Phosphorus

The Fuyang River belongs to the southern branch of the Ziya River system in the Haihe River Basin and originated from the Taihang Mountains. Due to the socio-economic development, industrial and agricultural production, and the large amount of water used in the city and the large-scale construction of upstream water conservancy projects, the river water has decreased, and the water environment in the river basin has continued to deteriorate. Therefore, this study takes the Fuyang River as the research object to analyze the spatiotemporal characteristics of water quality in the basin. The results show that total phosphorus presents winter> summer> autumn> winter, and dissolved total phosphorus presents winter> autumn> summer> spring.
