摘　　要：[目的]分析山西省晋中市耕地资源价值时空变化特征及影响因素,为实现耕地资源合理利用和科学管理提供科学依据。[方法]运用耕地资源价值核算体系对晋中市2015-2020年耕地价值进行核算,采用冷热点分析、地理加权回归等方法分析晋中市耕地资源价值空间变化特征及影响因素。[结果]①2015-2020年,晋中市耕地资源综合价值呈现出北高南低的总体特征,高值区(396.57~490.3)分布在寿阳县、榆次区,低值区(95.01~101.87)分布在和顺县、左权县,高值区与其他地区均存在显著性差异(p<0.05);②晋中市耕地资源价值在空间上存在集聚性,低值区分布在左权县、和顺县、榆社县、灵石县,高值区分布在榆次区、寿阳县。[结论]晋中市耕地资源价值影响因素有明显的空间异质性特征,呈现正相关的有集镇影响度、道路通达度、灌溉保证率、农村路网密度、复种指数、人均耕地面积,呈现负相关的为地形位指数。[Objective]The spatial-temporal variation characteristics and influencing factors of cultivated land value in Jinzhong City,Shanxi Province were analyzed in order to provide a scientific basis for the rational utilization and scientific management of cultivated land resources.[Methods]The value of cultivated land resources in Jinzhong City from 2015 to 2020 was calculated by using the value accounting system for cultivated land resources.The spatial variation characteristics and influencing factors of the overall mean value of cultivated land resources in Jinzhong City were analyzed by hot spot analysis and geographical weighted regression.[Results]①From 2015 to 2020,the overall average value of cultivated land resources was high in the north and low in the south.The high value area(396.57-490.3)was located in Shouyang County and Yuci District,and the low value area(95.01-101.87)was located in Heshun County and Zuoquan County,with large regional differences.②The comprehensive value of cultivated land resources in Jinzhong City exhibited spatial agglomeration,with low value areas located in Zuoquan,Heshun,Yushe,and Lingshi County,and high value areas located in Yuci District and Shouyang County.[Conclusion]The factors influencing cultivated land value had obvious spatial heterogeneity characteristics in Jinzhong City.Positive correlations were found with market town impact degree,road accessibility,irrigation guarantee rate,rural road network density,multiple cropping index,and per capita cultivated land area,while a negative correlation was found with topographic position index.
