山东畜禽粪便产生量估算及其环境效应研究

Estimated Yield and Environmental Effect of Dung Produced by Poultry and Livestock in Shandong Province

根据山东各市2010年初、年末畜禽存栏平均数,估算了各市和全省畜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,2010年山东省畜禽养殖业共产生1.98亿吨粪便,高于当年工业产生的固体废弃物;畜禽粪便及其中的氮、磷纯养分平均耕地负荷分别为26.38t/hm2,131.18kg/hm2和39.70kg/hm2。多个城市的畜禽养殖业已经对当地环境造成了污染。

The yield and environmental effect of dung produced by poultry and livestock in Shandong Province was estimated by using the average number of poultry and livestock raised in barn at the end of the year. The results were as follows: 198 million tons of dung was produced by animal production in Shandong Province in 2010. The dung yield was higher than that of solid waste produced by industrial production in the same year; the soil nutrient load of farmland for manure,nitrogen and phosphorus was 26. 38 t / hm2,131. 18kg / hm2and 39. 70 kg / hm2,respectively. Poultry and Livestock industry in some cities has caused environmental pollution has been occurred.
