Research on Non-Point Source Pollution Resulted from Livestock Breeding in Jiangxi Province
In recent years, continuous and steady development of livestock breeding in Jiangxi Province, while brings enormous economic benefits to society, also has brought great impaction on natural environment. This paper estimated the output of pollutants (CODcr、BOD5、NH3-N、TP 、TN) and average TP/TN load on unit area of farmland from livestock breeding in Jiangxi province and analyzed the distribution characteristics of pollutants during 2007--2009. During these three years, output of main pollutants (CODcr, BOD5, NH3-N, TP and TN) from livestock breeding in Jiangxi Province increased slightly; the high load regions of TP/TN were mainly distributed in the areas with high total and those with relatively smaller area of farmland although the output is lower. Researches indicated that the output of pollutants from livestock breeding in Jiangxi Province had exceeded the local farmland bearing capability. Relevant departments should readjust the agricultural production structure following the principles of unified planning and rational distribution in order to effectively control non-point pollution from livestock breeding.
