摘要
利用长沙市统计年鉴数据,对长沙市农业废弃物年度存量进行了估算及分析研究。结果表明:1998、2002、2006年及2010年,长沙市主要农作物秸秆年度产生量为235.33万～299.84万t,畜禽粪尿年度产生量为1 377.08万～1 713.07万t,作物秸秆和畜禽粪尿产量均未表现出年度间规律性变化。长沙市农业废弃物污染治理应以畜禽粪尿排放为治理重点。
The annual stock of main agricultural wastes in Changsha city was estimated and analyzed using data from statistical yearbook of Changsha city. The results showed that the yields of crop stalks and livestock and poultry manure in 1998, 2002, 2006 and 2010 were 235.33×10^4-299.84×10^4 t and 1 377.08×10^4-1 713.07×10^4 t, respectively, and both of them changed irregularly between the years. Therefore, treating pollution of agricultural wastes in Changsha city should focus on discharge management for livestock and poultry manure.
