Analysis And Control Measures For Agircultural Non-point Source Pollution Survey In Shangrao

Non-point source pollution control of agro-ecological environment has become a majortheme of modern agriculture and social sustainable development. In order to investigate thebasic law of non-point source pollution status, change and distribution, planting, animalhusbandry and aquaculture had been researched in the year of2008in Shangrao. Theresults show that:(1) Among the emissions of three major pollutants, the total nitrogen is7358.86t,phosphorus is754.33t, ammonia nitrogen is1478.36t, COD is13238.69t, copper is6443.83t, zinc is9073.34t and pesticide is1752.34t.(2) Of all the watershed with pollutant emissions, Xinjiang river occupied first placeand Lean River came second. Among the administrative area that emit pollutan, Poyangand Yugan are major emitters, followed by Shangrao, Yushan, Wannian and Guangfeng.(3) A comprehensive analysis on the pollution situation of agricultural sources inShangrao was presented. Among the three major agriculture industries, the sewage withoutdeep processing discharge, littering and defecated by livestock and poultry, makesenvironment seriously polluted. It’s the primary factor for environmental contamination andthe aquaculture and planting followed. Planting pollution to water is mainly attributed tooverusing of chemical pesticide, which with low utilization coefficient. Aquacultureresulted in a direct effect on the aquaculture water because its escaping from buffer layer. Itdoes a large harm to environment than other aquaculture model.A integrated computation were executed a on the pollution discharge quality of farming,livestock and poultry breeding and aquaculture.We found that Poyang ranks the first placein agricultural emissions of pollutants because it occupied the largest plough and farmingscale. Followed by Yugan, Shangrao, Yushan and Wannian.To solve the above problems, the government should do as follows: strengthen itsleadership, plan agricultural and industrial layout reasonably; formulate relevant laws andregulations as soon as possible; construct of agricultural infrastructure, and gradually formplanting and raising mode of ecological agriculture; promote scientific fertilization, applypesticide technology; develop the rural energy, implement rural clean project; intensifymonitoring of agricultural nonpoint source pollution and enforcement of the law; developthe animal husbandry scientifically and reasonably; develop rural non-point sourcepollution control technologies; actively pursue scale management; strengthen theconstruction of the promotion and propaganda system.
