| 摘 要： | 本文通过估算1985年–2005年期间福建省畜禽养殖业粪便排放量变化，并通过耕地负荷、流失量等参数评价了福建省畜禽养殖业废弃物污染风险。评估结果表明：1985年福建省的畜禽粪便产生量为2180万吨，而到了2005年达到了4249万吨，翻了一番。1985年时福建省畜禽粪便耕地负荷、纯氮耕地负荷和纯磷耕地负荷分别为15.2 t?hm-2、96 kg?hm-2和45 kg?hm-2；而到了2005年已分别达到了29.6 t?hm-2、181 kg?hm-2和96 kg?hm-2。同时，福建省畜禽粪便中氮、磷、钾流失量分别从1985年的3.26万t、0.70万t和4.47万t增长到6.05万t、1.85万t和10.53万t。2005年福建省畜禽养殖业的氮排放量分别是同期工业废水和生活污水氮排放量的7.4倍和1.9倍，已成为福建省流域水体富营养化的主要原因，其贡献已大大超过工业废水和生活污水。

| Abstract: | The pollution risk of livestock and poultry breeding industry in Fujian province from 1985 to 2005 was assessed through the production amounts of animal manure of livestock and poultry breeding industry and the parameter of cropland load and loss amount. Assessment results are as follows： The production amounts of animal manure of livestock and poultry breeding industry of Fujian in 1985 was 21.8 million tons, and in 2005 reached 42.5 million tons, more than doubled. The average cropland load of animal manure and its N, P2O5 nutrient in 1985 were 15.2 t/hm^2, 96 kg/hm^2 and 45 kg/hm^2; but in 2005 were 29.6 t/hm^2, 181 kg/hm^2 and 96 kg/ hm^2. And the loss amounts of N, P2O5, K2O nutrient of animal manure in 1985 were 32,600 t, 7 000 t and 44 700 t; but in 2005 were 60 500 t, 18 500 t and 105 300 t. In 2005, N emissions of livestock and poultry breeding industry in Fujian are 7.4 times the amount of industrial wastewater and 1.9 times the amount of domestic sewage. Hence, the livestock and poultry breeding industry of Fujian Province has become one of the most important pollution sources of eutrophication. |
