摘要
估算了河北省家禽养殖业粪便产生量,并对由此产生的环境效应进行了评价。结果表明,除2006年外,河北省家禽出栏量和粪便产生量均保持约5%的增长速度。2006年,河北省家禽养殖粪便及其中的氮、磷纯养分平均耕地负荷分别为28t/hm2、N178kg/hm2、P73kg/hm2,潜在环境污染严重。
The discharge amount of domestic poultry manure in Hebei Province was estimated, and its environmental effect was analyzed. The results showed that both the amount of domestic poultry on hand and the discharge amount of produced poultry manure were increased by 5% every year except in 2006. The average pollution load of poultry manure, pure P and pure N was 28 t/hm2, 178 kg/hm2 and 73 kg/hm2 in Hebei Province, which indicated serious potential environmental pollution.
