Table 3: Pollution load and the total discharge of the dissolved pollution in 18 cities of Henan Province. were Puyang and Luohe. The TN, TP, NH\({}_{4}^{+}\)-N, and COD of Puyang were 0.1918 kg\(\cdot\)km\({}^{-2}\), 0.0107 kg\(\cdot\)km\({}^{-2}\), 18.2881 kg\(\cdot\)km\({}^{-2}\), and 11.6963 kg\(\cdot\)km\({}^{-2}\), respectively. The pollution load was highest in the northeast region. Finally, for livestock pollution, the cities with the highest pollution loads were Zhoukou, Kaideng, and Luohe. The TN, TP, NH\({}_{4}^{+}\)-N, and COD of Zhoukou were 2.0180 kg\(\cdot\)km\({}^{-2}\), 0.0901 kg\(\cdot\)km\({}^{-2}\), 61.8875 kg\(\cdot\)km\({}^{-2}\), and 11.2805 kg\(\cdot\)km\({}^{-2}\), respectively. It is shown in Figure 7 that the pollution loads were highest in the east. For dissolved pollution from urban runoff, the four pollutant elements were allocated with a proportional coefficient based on the total pollution dissolved by rainfall; therefore, the four pollutants show similar patterns in the four subfigures of Figure 7. The subfigures in Figure 11 display the same pattern for the other three types of dissolved pollution. For the dissolved pollution, the pollution load and the total discharge of the four types of pollution (Urban runoff, Agricultural runoff, Rural resident pollution and Livestock pollution) are shown in Table 4.  
Upon analyzing each pollution type's contribution to each pollutant in Table 4, we can see that TN and TP were highest and second highest in agricultural runoff.
