中国畜禽粪便资源结构分布及发展展望

随着近年来经济的发展和产业结构的调整，畜禽养殖业发展迅速，同时畜禽粪便的产生量也在迅速增加。为此利用全国第一次污染源普查的相关指标和相关文献中排泄系数，在综合考虑畜禽饲养周期的情况下，估算出2009年中国畜禽粪尿产生总量约为21.83亿t猪粪当量，其中河南、山东、四川和内蒙古的畜禽粪尿产生量均超过1.50亿t猪粪当量。并利用2020年畜禽产品需求量的预测值，估算出2020年的畜禽粪尿产生量为28.11亿t猪粪当量。通过对畜禽粪尿产生量的估算，有利于明确对畜禽粪便总量和分布的认识，为畜禽粪便处理方法的选取和相关政策的制定奠定基础。

The Structure Distribution and Prospect of China Manure Resource

With the economic development and industrial structure adjustment recently, livestock and poultry breeding industry is developing rapidly while the amount of excrement production is rapidly increasing. Taking advantage of excretion factors in the first national census of pollution sources and relevant references, considering livestock and poultry breeding cycle, this paper estimated the amount of livestock and poultry excrement of China was about 2.218 billion tons of pig manure equivalent. What’s more, three provinces’ including Henan, Shandong, Sichuan and Inner Mongolia volumes were all over 150 million tons of pig manure equivalent. Based on the demand for livestock products in 2020, this paper estimated the amount of excrement production was about 2.825 billion tons of pig manure equivalent. Estimating the amount of manure production was propitious to recognize the volume and distribution of livestock and poultry excrement meanwhile lay a foundation for the selection of animal excrement treatment methods and the formulation of relevant policies.
