我国畜禽养殖业规模化和集约化程度越来越高,大量畜禽粪便排放导致环境污染日趋严重,阻碍了农业可持续发展。文章以区域畜禽养殖农户和有机肥企业的实地调查及年鉴数据为基础,概述畜禽粪便资源化利用现状,对比畜禽粪便和施用化肥所含养分总量,分析畜禽粪便资源化利用程度低等问题。结果表明：研究区畜禽粪便资源总量为129.23万吨,商品化有机肥资源仅占总量的8.13%,农民直接购买用于传统肥料占总量的55.87%,闲置丢弃畜禽粪便约达36.00%,有机肥资源浪费较大,畜禽粪便污染较为严重;从2006-2012年畜禽粪便所含养分量与同期施用化肥养分量的平均替代率为55.55%,畜禽粪便资源化发展潜力巨大。基于此结果,提出了相关对策建议。

The scale and intensive livestock levels are increasing in China, The environmental pollutions resulted from large livestock excrement emissions are serious, which has hindered sustainable agricultural development. Based on Shenyang Rural Statistical Yearbook and regional field surveys data of livestock farmers and organic fertilizer companies, the paper summarizes livestock manure utilization status, compares the total nutrient of livestock manure with fertilizer, and analyzes the issues as low resource utilization ratio of livestock manure. The results show that： the total of livestock manure in the study area is 1.29 million tons; the commercial organic fertilizer utilization account for 8.13%, farmers purchase directly for traditional fertilizer account for 55.87%; dumped livestock manure account for 36.00%, and the Organic fertilizer resource wasting and livestock manure pollution are more serious; The average replacement rate of livestock manure nutrient to fertilizer nutrient is 55.55% from 2006-2012, so the livestock manure recycling potential is large. Based on the foregoing analysis, relative suggestions are put forward.
