基于Meta方法对东北地区畜禽粪污利用率评价

Evaluation on utilization rate of livestock and poultry manure in Northeast China based on Meta-analysis

为研究统计东北地区畜禽粪污综合利用率、养殖场设备配套率以及其他利用方式,采用Meta分析方法,以“畜禽粪污、畜禽养殖污染、畜禽废弃物、牛粪、猪粪、鸡粪、羊粪”等为主题词,检索了2000—2020年公开发表的所有相关文献,通过文献排除标准进行筛选和整理,最终纳入文献对其进行质量评价,提取数据并建立数据库进行统计分析,采用95%CI置信区间评估的方法,表示数据真值较大概率在此区间,区间范围内以95%的置信度来评估数据。结果表明:东北地区畜禽粪污的总体综合利用率为59%(53%~65%,95%CI),从研究年限来看,2010—2015年为59%(47%~71%,95%CI),2016—2020年为64%(50%~78%,95%CI);东北地区养殖场设备配套率为65%(56%~75%,95%CI),从不同省份来看,吉林省为57%(44%~70%,95%CI),辽宁省为88%(83%~93%,95%CI),黑龙江省为66%(44%~88%,95%CI);畜禽粪污用于有机肥制作的概率为16%(10%~22%,95%CI);畜禽粪污的堆肥还田率为56%(45%~67%,95%CI);畜禽粪污沼气利用率为9%(3%~15%,95%CI)。通过数据整合分析,为畜禽粪污资源化利用提供数据支撑,以期解决东北地区畜禽粪污处理问题,减少资源浪费,保护农业环境。

In order to study the comprehensive utilization rate of livestock and poultry waste,the matching rate of livestock farm equipment and other utilization methods in Northeast China,we adopted the Meta analysis method and took“livestock and poultry feces,livestock and poultry pollution,livestock and poultry waste,cow manure,pig manure,chicken manure,sheep manure”as the main inscriptions.All relevant literatures published between 2000 and 2020 were searched,and the documents were screened and sorted through the literature exclusion criteria,and finally included and the quality was evaluated,the data was extracted and the database was established for statistical analysis,and the 95%CI confidence interval evaluation method was used to evaluate the data within the interval with 95%confidence.The results showed that the overall comprehensive utilization rate of livestock and poultry manure was 59%(53%~65%,95%CI)in Northeast China,and 59%(47%~71%,95%CI)in 2010-2015 and 64%(50%~78%,95%CI)in 2016-2020;the equipment matching rate of breeding farms in Northeast China was 65%(56%~75%,95%CI).From the perspective of different provinces,Jilin Province was 57%(44%~70%,95%CI),and Liaoning Province was 88%(83%~93%,95%CI),66%in Heilongjiang Province(44%~88%,95%CI);the probability of manure used for organic fertilizer production was 16%(10%~22%,95%CI),the return rate of manure was 56%(45%~67%,95%CI),and the utilization rate of biogas was 9%(3%~15%,95%CI).Through integrated analysis,it provides data support for the utilization of livestock manure resources,with a view to solving the problem of livestock manure treatment in Northeast China,reducing resource waste,and protecting the agricultural ecological environment.
