In recent years,the total nitrogen flux of rivers into the sea has become the key to improve the water quality of coastal waters,and has been paid attention to for a long time.Despite a series of measures taken by governments at all levels,the mean value of total nitrogen in rivers entering the sea has rebounded,the continuous rebound of the total nitrogen concentration of rivers entering the sea in the Bohai Sea has seriously affected the improvement of river water quality and the effect of Marine ecological environment protection.Marine ecological and environmental problems are manifested in the sea,and their roots are on land.The purpose of this paper is to analyze the causes of the rebound of the mean value of total nitrogen in rivers entering the sea,and put forward corresponding countermeasures,in order to provide references for water environment management and ecological protection in China's coastal areas.
