Based on the livestock statistical data of 31 provinces of 1997 - 2004, this paper analyzed the structure of livestock and the variation of fecal nitrogen pollution load in China. The results showed that the relationship between structure of livestock and the economic situation of different provinces was obviously significant. The nitrogen pollution load of livestock was increasing gradually from the northwest to the southeast, and could be divided into relative higher and lower parts, in line with the boundary of 400 mm rainfall of China. Meanwhile, in Beijing and Shanghai, with population concentrated and economy developed, the livestock had developed at a higher speed. However, in the last few years, the developing speed had been decreased slowly; the pollution load had begun to decrease, while the pollution load of livestock in the provinces around Beijing and Shanghai has been increased gradually. Additionally, it is found that only eight provinces are not facing the risk of livestock pollution theoretically.
