基于2010-2020年山西省县(市、区)化肥施用相关数据,运用空间自相关分析、泰尔指数和空间计量模型等方法,从多维度研究分析了山西省化肥施用量的时空特征演变、区域差异及化肥施用强度的驱动因素。结果表明,山西省化肥施用量整体呈"N"形的时间变化和集聚特征的空间分布现象。具体而言,"N"形时间变化的统计学高值为2013年,低值为2019年;集聚特征的空间分布主要表现为热点区域集中分布在晋南地区,冷点区域集中在吕梁山区,且存在明显的空间不均衡特征,晋南地区、忻定盆地、大同盆地等地化肥施用量明显高于其他区域。山西省化肥施用强度整体呈北低南高、逐年递增的现象,施用强度差异主因为区域内差异。具体而言,晋北地区的化肥施用强度最低,其次是晋中地区,而晋南地区的化肥施用强度最高,且处于逐年平稳增长的时间变化趋势;泰尔指数结果表明,区域内的差异是区域总差异的主因,总差异呈波动变化,2018年达最高值;县域化肥施用强度与施用量空间变化特征基本一致。山西省化肥施用强度主要影响因素中,人均耕地面积、农业种植结构、农业劳动力转移对化肥施用强度呈显著负向影响,人口数量呈正向影响,农村居民人均收入及农业技术进步无显著影响。
Spatio-temporal characteristics evolution and driving factors analysis of chemical fertilizer application in Shanxi Province
Based on the relevant data of fertilizer application in the counties(cities and districts)of Shanxi Province from 2010 to 2020,the spatial auto-correlation analysis,Theil index and spatial econometric model were used to explore and analyze the spatio-temporal characteristics of fertilizer application,regional differences and driving factors of fertilizer application intensity in Shanxi Province from a multidimensional perspective.The results showed that the amount of chemical fertilizer applied in Shanxi Province showed an"N"type temporal change and showed concentration characteristics spatially.To be specific,the statistically high value of the chemical fertilizer applied amount was in 2013 and the low value was in 2019.The hot spots were concentrated in southern Shanxi,and the cold spots were concentrated in the Luliang Mountain Area.There was an obvious spatial imbalance.The fertilizer application amount in southern Shanxi,Xinding Basin and Datong Basin was significantly higher than that in other regions.The fertilizer applica-tion intensity in Shanxi Province showed the phenomenon of"low in the north,high in the south,increasing year by year",with the main reason for the intensity difference being intra-regional differences.To be specific,the fertilizer application intensity in northern Shanxi was the lowest,followed by that in central Shanxi,while that in southern Shanxi was the highest,and it was in a time trend of steady growth year by year.Theil index results showed that intra-regional differences were the main cause of the total regional differ-ences,and the total differences fluctuated,reaching the highest value in 2018.The spatial variation characteristics of fertilizer applica-tion intensity and amount at the county level were basically consistent.Among the main influencing factors of the fertilizer application intensity in Shanxi Province,the per capita cultivated land area,agricultural planting structure and agricultural labor transfer had a significant negative impact on the fertilizer application intensity,while the population had a positive impact,and the per capita income of rural residents and agricultural technology progress had no significant impact.
