A study of rural livestock and poultry breeding pollution problems in china's urbanization process

Abstract

In the process of rapid urbanization between 2001 and 2010, the livestock and poultry industry in China was characterized by the rigid growth in number and the large scale and intensive trend in breeding mode, thereby causing serious pollution of soil, water and air. The results in this paper show that the number of livestock and poultry manure nationwide was about 3.203 billion tons in 2010, 1.33 times that of the number of industrial solid waste and a 10.55%increase than in 2001. Where spatial pattern is concerned, compared with the year 2001, the cultivated land load of manure (t/hm2) and of nitrogen/phosphorus nutrient (kg/hm2) were both increased almost in all areas except North China in 2010. Besides, it is noteworthy that the livestock and poultry pollution posed a big threat to local environment in some areas. © Springer-Verlag Berlin Heidelberg 2014.
