Study On The Correlation Between COD Emission And Scale Of Livestock And Poultry In China

Since reform and opening to the outside along with the rapid development of livestock and poultry breeding industry, the scale breeding of livestock and poultry breeding industry has become the backbone industry of regional agriculture and rural economy development in our country. On the other hand, at the same time of rapid development, livestock and poultry breeding pollution has gradually become the main source of rural non-point source pollution in China.This paper studies the main work is through the statistics, calculating the national various provinces, municipalities directly under the central government in2007tons of animal by-products and COD emissions of livestock and poultry products as well as the mass breeding level and a series of data, finally obtaining "livestock and poultry breeding tons of animal by-products COD emissions" and "national provincial municipality directly under the central government of livestock and poultry breeding scale numerical" two sets of data. Research topic to analyze correlation between these two sets of data as a starting point, through the correlation results monadic linear regression analysis method, as taking the analysis research foundation of breeding, scale effect on environmental pollutionTrough the calculation of a certain amount of data statistics, the paper finally concludes "livestock farming COD emission" and "breeding scale" strong proportional correlation between. Combined with the study of individual case analysis, the article at last put forward some about promote the development of livestock farming scale combined with aquaculture environmental work of reference point of view and opinions.Paper used research methods mainly include:observation and literature research method, mathematical statistics method, information, and case analysis and other methods...
