Temporal and Spatial Variation of Agricultural Non-point Source Pollution in the Pearl River Delta from 2010 to 2020
To explore the agricultural non-point source pollution in the Pearl River Delta in recent 10 years, uses inventory analysis to analyze the temporal and spatial variation of farmland fertilizer, livestock breeding, aquaculture, farmland solid waste, and rural agricultural non-point source pollution i...

| description | To explore the agricultural non-point source pollution in the Pearl River Delta in recent 10 years, uses inventory analysis to analyze the temporal and spatial variation of farmland fertilizer, livestock breeding, aquaculture, farmland solid waste, and rural agricultural non-point source pollution in nine cities involved in the Pearl River Delta, including Guangzhou, Shenzhen, Zhuhai, Foshan, Huizhou, Dongguan, Zhongshan, Jiangmen and Zhaoqing. The results show that the total load of agricultural non-point source pollution in the Pearl River Delta decreased by 17.77% from 2010 to 2020. Specifically, the COD pollution load decreased by 8.20%, the TN pollution load decreased by 21.04%, and the TP pollution load decreased by 8.18%. The contribution rate of pollution load is as follows: Zhaoqing > Jiangmen > Huizhou > Guangzhou > Foshan > middle mountains > Zhuhai > Dongguan > Shenzhen. The emission intensity of pollutants from farmland fertilizer and livestock breeding decreased by 26.01% and 37.07%, respectively. The emission intensity of aquaculture, farmland solid waste, and rural domestic pollutants increased by 36.62%, 22.79%, and 14.39%, respectively. |
