畜禽养殖废弃物资源化利用的绩效评价及制约因素研究以江西省为例

Research on Performance Evaluation and Restrictive Factors of Resource Utilization of Livestock and Poultry Wastes: Taking Jiangxi Province as An Example

  • 摘要: 畜禽废弃物资源化利用是对“绿水青山就是金山银山”理念的体现,也是生态文明建设的重要举措。通过对畜禽废弃物资源化利用的分析,旨在提高畜禽废弃物资源化的利用,减少畜禽粪污对环境的污染。本文从经济效益、生态效益、社会效益三个维度构建了畜禽废弃物资源化利用水平的综合评价指标体系,运用灰色关联度法对江西省畜禽废弃物资源化利用水平进行综合测度,随后采用 Tobit 模型分析了畜禽废弃物资源化利用的影响因素。实证结果表明:江西省畜禽废弃物资源化利用水平总体呈现先降后升再降的趋势,生态效益总体呈现上升趋势,经济效益呈现下降趋势,社会效益与综合效益呈现相同的变化趋势。人均地区生产总值、地区平均受教育年限对提高畜禽废弃物资源化利用有显著的正向作用,处理农业废弃物沼气工程产气量对畜禽废弃物资源化利用不具影响。根据分析结果,针对畜禽废弃物资源化利用提出建议。

     

    Abstract: The resource utilization of livestock and poultry waste is the embodiment of the concept of “lucid waters and lush mountains are invaluable assets” , and is also an important measure for the construction of ecological civilization. Through the analysis of the resource utilization of livestock and poultry waste, the aim is to improve the utilization of livestock and poultry waste resources and reduce the pollution of livestock and poultry manure to the environment. This paper constructs a comprehensive evaluation index system for the resource utilization level of livestock and poultry waste from the three dimensions of economic benefit, ecological benefit and social benefit. The Tobit model is used to analyze the influencing factors of the resource utilization of livestock and poultry waste. The empirical results show that the overall utilization level of livestock and poultry waste in Jiangxi Province presents a trend of first decreasing, then increasing and then decreasing. Showing a downward trend, social benefits and comprehensive benefits show the same trend of change. The GDP per capita and the average years of education in the region have a significant positive effect on improving the resource utilization of livestock and poultry waste. According to the analysis results, suggestions are put forward for the resource utilization of livestock and poultry waste.
