Measurement and Characteristic Analysis of Agricultural Non-Point Source Pollution Load in Jiangxi Province
摘要
Abstract
Agricultural sources are the main contributors to non-point source pollution in China,and its contribution rate to total pollutants is much higher than that of industrial source and domestic source.In order to reveal the spatial and temporal characteristics of agricultural non-point source pollution in Jiangxi Province,identify its main pollution source and pollutant and priority control areas,the study used the pollu-tion coefficient method and equivalent pollution load method to calculate the COD,NH3-N,TN and TP emissions of agricultural non-point source pollution in Jiangxi Province from 2005 to 2020.The results show that the emissions of COD,NH3-N,TN and TP are increased by 11.77%,-22.11%,-8.99%and 6.60%respectively.The total emissions of pollutants from rural life and agriculture show a downward trend,while those from livestock husbandry and aquaculture show an upward trend.The contribution rate of pollution sources is livestock hus-bandry＞rural life＞aquaculture＞agriculture,with livestock husbandry being the main pollution source,and TN being the main pollutant.The spatial distribution of pollution intensity in Jiangxi Province shows a high concentration in the central region and a low concentration in the surrounding areas.Nanchang County,Fengcheng City,Zhangshu City,Chongren County,Yujiang District,Xinzhou District,Taihe County and Ji'an County are the priority control areas for agricultural non-point source pollution in Jiangxi Province,and the livestock and poultry industry is the key pollution source in the priority control area.关键词
