摘要
为探讨不同类型农业废弃物能源化利用方式对农村能源可持续性的影响,根据1990—2019年黄河流域9省(区)60个地级行政区(市、州、盟)的农作物产量和畜禽数量,采用草谷比法和排泄系数法计算出其农业废弃物资源量。同时,从能源消耗、能源结构、环境排放三方面构建农村能源可持续性指标体系。结果表明:1990—2019年,黄河流域农业废弃物年产生量呈现先增加后减少的“双峰”变化趋势,峰值分别出现在1996年和2006年,分别为6.81亿t和7.06亿t。2019年黄河流域农村能源可持续性平均得分为0.3237,且省域差异显著,呈现上下游高、中游低的空间分布特征。最后,依据不同类型农业废弃物能源化利用方式对农村能源可持续性影响程度、秸秆与畜禽粪便比率以及秸秆资源密度,推荐了适合各地级行政区的农业废弃物能源化利用方式。
In this study,we discuss the impact of different types of agricultural waste energy utilization methods on rural energy sustainability.According to the crop yield and number of livestock and poultry in 60 prefecture-level administrative regions(cities,prefectures,and leagues)in nine provinces in the Yellow River basin from 1990 to 2019,the amount of agricultural waste resources was calculated by using the ratio of grass to grain and excretion coefficient.Additionally,a rural energy sustainability index system was constructed from three aspects:energy consumption,energy structure,and environmental emissions.The results show that from 1990 to 2019,the annual production of agricultural waste in the Yellow River basin showed a“double peak”trend of increasing first and then decreasing,with peaks of 681 million t and 706 million t in 1996 and 2006,respectively.In 2019,the average score of rural energy sustainability in the Yellow River basin was 0.3237,and the provincial differences were significant,showing high upstream and downstream and low midstream spatial distribution characteristics.According to the impact of different types of agricultural waste energy utilization methods on rural energy sustainability,the ratio of straw to livestock and poultry manure,and the density of straw resources,the energy utilization methods of local administrative regions are recommended.
