摘  要:通过DPSIR模型构建农作物秸秆综合利用水平评价指标体系,结合2013—2022年我国31个省份(不含港澳台)的面板数据,利用熵值法、Dagum基尼系数、核密度估计法与Moran’s I对秸秆综合利用水平区域间差异与时空动态演化展开研究。结果表明:2013—2022年,我国农作物秸秆综合利用水平显著提高,地区发展水平存在差异,东部、中部与西部间差异明显;全国整体极化现象减弱,中部地区存在多地分化现象,东部与西部地区无明显极化现象;我国农作物秸秆综合利用水平存在显著的空间正相关关系,并在地理位置上存在高度聚集性,空间集聚特征稳定。Combined with the panel data of 31 provinces(municipalities and districts)in China from 2013 to 2022(excluding Hong Kong,Macao and Taiwan),the entropy method,Dagum Gini coefficient,kernel density estimation method and Moran's I were used to study the regional differences and spatiotemporal dynamic evolution of straw comprehensive utilization level in China.The results showed that from 2013 to 2022,the level of comprehensive utilization of crop straw in China was significantly improved,and there were differences in regional development levels,and there were obvious differences between the eastern,central and western regions.The overall polarization phenomenon of the whole country was weakened,and there was a multi-regional differentiation phenomenon in the central region,but there was no obvious polarization phenomenon in the eastern and western regions.There was a significant spatial positive correlation between the comprehensive utilization level of crop straw in China,and there was a high degree of aggregation in geographical location,and the spatial agglomeration characteristics were stable.
