2010-2020年珠江三角洲地区农业面源污染时空变化研究
Temporal and Spatial Variation of Agricultural Non-point Source Pollution in the Pearl River Delta from 2010 to 2020
摘要
Abstract
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.关键词
