Temporal and spatial characteristics and source apportionment of agricultural non-point source pollution in Jiangsu Province based on inventory analysis
摘要
Abstract
The inventory analysis method was used to determine the discharge amount, density, and contribution of chemical oxygen demand (COD), total nitrogen (TN), and total phosphorus (TP) from different types of agricultural non-point sources, including chemical fertilizer application, livestock farming, aquaculture, farmland solid waste, and rural life in Jiangsu province and other 13 cities in Jiangsu. The results indicated that the discharge amount of COD, TN, and TP were increased from 64.20, 54.29, and 4.78 to 96.88, 72.87, and 8.33 ten thousand tons, respectively. The densities of COD, TN, and TP were increased from 20.978, 17.74 and 1.560 mg稬-1 to 31.654, 23.810 and 2.721 mg稬-1 in Jiangsu province from year 1990 to 2009. There were significant differences in the 13 cities in Jiangsu. For example, the discharge amount of COD, TN, and TP were in the range of 24,59-172.63, 16.19-144.03 and 1.77-17.57 ten thousand tons, and the densities of COD, TN, and TP were 11.261-105.597, 6.135-90.005 and 0.813-9.239 mg稬-1 separately. Livestock farming was the most important source of COD and TP, while chemical fertilizer application was the most important source of TN.关键词
