Stability prediction of inorganic nitrogen in water environment of Bohai Sea

The water pollution of Bohai Sea is more and more serious recently, and inorganic nitrogen is one of the main pollutants. Accurate stability prediction of inorganic nitrogen could provide an important base for optimizing the monitoring station and managing the marine pollution of Bohai Sea. In this paper, the probability of each type of inorganic nitrogen were predicted by IDW interpolation method and regression analysis method on the base of the trend monitoring data of the inorganic nitrogen from the year 2002 to 2013. The probability of the stability of inorganic nitrogen from the year 2014 to 2016 was also predicted, furthermore, the stability of inorganic nitrogen in Bohai Sea was divided into high, medium, and low zones, which could provide a scientific base for monitoring station layout and controlling the marine pollution of Bohai Sea.
