乡村振兴背景下农业产业强镇空间分布特征及影响因素

Spatial Distribution Characteristics and Influencing Factors of Strong Towns in Agricultural Industry under the Background of Rural Revitalization

农业产业强镇建设是乡村产业振兴的重要内容和有力抓手。运用最近邻指数、核密度分析、空间趋势面分析等方法对811个农业产业强镇的空间分布特征进行分析,并利用地理探测器探测其影响因素。结果表明:①从全国尺度看,农业产业强镇呈现出显著的空间集聚分布特征,形成鲁豫交界、苏浙交界、川渝交界三个高密度核心区。②从省域尺度看,山东、河南、四川是主要的农业产业强镇分布省份,农业产业强镇在省际间表现出“东高西低、南北持平”的空间分布格局。③农业机械化、农业人力资本、财政支农是农业产业强镇空间分布的主要影响因素,各影响因素的交互作用强化了农业产业强镇空间分异效果,农业机械化与农业人力资本、农业人力资本与农业产业结构为影响农业产业强镇的主导交互因素。

The construction of strong towns in agricultural industry is an important content and a powerful starting point for the revitalization of rural industry.The spatial distribution characteristics of 811 strong towns in agricultural industry are analyzed by using the methods of nearest neighbor index,nuclear density analysis and spatial trend surface analysis,and the influencing factors are detected by geographic detectors.The results show that:①from the national scale,strong towns in agricultural industry show significant spatial agglomeration and distribution characteristics,forming three high-density core areas:the junction of Shandong and Henan,the junction of Jiangsu and Zhejiang and the junction of Sichuan and Chongqing.②From the provincial scale,Shandong,Henan and Sichuan are the main provinces where strong towns in agricultural industry are distributed.Strong towns in agricultural industry show a spatial distribution pattern of"high in the East,low in the West and flat in the north and South"among provinces.③Agricultural mechanization,agricultural human capital and financial support for agriculture are the main influencing factors of the spatial distribution of strong towns in agricultural industry.The interaction of various influencing factors strengthens the spatial differentiation effect of strong towns in agricultural industry.Agricultural mechanization and agricultural human capital,agricultural human capital and agricultural industrial structure are the leading interactive factors affecting strong towns in agricultural industry.
