种养结合能否提升肉羊养殖环境技术效率?
Can the combination of planting and breeding improve the environmental technical efficiency of mutton sheep breeding?MTE model analysis based on different combination modes of planting and breeding
摘要
Abstract
In order to explore whether different modes of combination of planting and breeding can improve environmental technical efficiency of mutton sheep breeding,the environmental technical efficiency of mutton sheep breeding was measured based on Super-SBM model in this study.The influence of different combination modes of planting and breeding on the environmental technical efficiency of mutton sheep breeding and its influence path were monitored based on multiple treatment effect model(MTE model).The results show that:1)The combination of planting and breeding can improve the environmental technical efficiency of mutton sheep breeding.The internal cycle combination of planting and breeding mode has a stronger improvement effect on the environmental technical efficiency of mutton sheep breeding than the external cycle combination of planting and breeding mode;2)The internal circulation model improves the environmental technical efficiency of mutton sheep breeding by improving the technical efficiency of breeding and reducing non-point source pollution and C emissions,while the external circulation model mainly improves the environmental technical efficiency of mutton sheep breeding by reducing non-point source pollution;3)The internal circulation model is more conducive to improving the environmental technical efficiency of small-scale mutton sheep breeding,while the external circulation model only improves the environmental technical efficiency of large-scale mutton sheep breeding.关键词
