清江流域畜禽粪便产生量估算及环境效应分析
Estimation of Production Amount and Environmental Effect of Livestock Manurein Qingjiang Basin
摘要
Abstract
Based on the livestock data in Qingjiang basin from 2008 to 2013,the amount of livestock manure were calculated by using the excretion coefficient method, and their environmental effect on farmland and water was evaluated.The results indicated that the average farmland pollution loading was 20.30 t/hm2 during 2008 to 2013, already showing some environmental effect.According to the present trend, the loading would reach 30 t/hm2 in 2016, which might affect environment seriously.Among all the pollutants, the amount of COD (223057.59 t) was the most, accounting for 39.72% of the total.The amount of ammonia nitrogen (18433.59 t) was least, accounting for 3.48% of the total.Among the various pollutants, TN and TP had most significant influence on water environment, with equal-standard discharge rate of 40.43% and 34.58%, respectively.The contribution of pig, sheep, cow and poultry to water pollution was 55.83%, 26.41%, 14.06% and 3.68%, respectively.Among the ten counties and cities in Qingjiang basin, Yidu City contributed most to water pollution, with a rate of 16.33%, followed by Changyang Country, Enshi City, Lichuan City, Badong Country, Jianshi Country, Xuan'en Country, Xianfeng, Wufeng and Hefeng Country, with the corresponding contribution being 14.68%, 13.24%, 11.69%, 10.72%, 9.90%, 6.78%, 6.66%, 5.20% and 4.80%, respectively.关键词
