In order to preserve the ecological environment of rural areas and lessen the amount of pollution caused by livestock and poultry production

it is necessary to propose and implement efficient preventative and control measures. Through the large-scale livestock and poultry breeding pollutant emissions measured and caused by the analysis of the causes

it was determined that the emission of the chemical oxygen demand（COD） of the livestock and poultry breeding of the large-scale cultivation of the entire district was 46 367.59 t

and the ammonia nitrogen emission was 981.57 t in 2020. It was discovered after investigation analysis that due to lack of necessary guidance and planning

the zoning classified management was not implemented

with unreasonable livestock and poultry breeding layout

the disconnect of breeding and raising. In addition

some of the supporting facilities for prevention and control of the livestock and poultry breeding pollution were not in place

with the ineffective treatment of the pollutants like the excrements of livestocks

waste water and so on

causing environmental pollution

so that the sustainable development of the livestock and poultry breeding was restricted. Therefore

it is an important channel to achieve sustainable development for intensifying pollution prevention and adopting the combination of breeding and raising

as well as agriculture and animal husbandry cycle.
