摘要: 以长江经济带445个农业产业强镇为研究对象,综合运用最近邻指数、不均衡指数、核密度分析、空间相关分析、地理探测器等方法揭示其空间分布特征及影响因素。结果表明:①长江经济带农业产业强镇空间结构存在差异,呈集聚分布特征。②核密度表现为“双核、四高、四低”的分布态势。③长江经济带农业产业强镇呈显著的空间正相关,形成了“上中游交界、长三角交界热,上游西部、中下游交界冷”的冷热点分布格局。④农业产业投入是影响长江经济带农业产业强镇空间分布的主导因素,农业产业基础是关键因素,农业产业产出是直接因素,农业产业区位是相关因素。

Abstract: Taking 445 top agricultural towns in the Yangtze River Economic Belt as research objectives, this study investigated and revealed the spatial distribution characteristics and influencing factors with multiple methods. The methodology integrated the nearest neighbor index, disequilibrium index, kernel density analysis, spatial correlation analysis, geographic detector, et al. The results show: ①The top agricultural towns in the Yangtze River Economic Belt are differences in spatial structure, showing agglomeration distribution characteristics. ②The nuclear density shows the distribution trend of dual-core, four high, and four low. ③The top agricultural towns in the Yangtze River Economic Belt have a significant positive spatial correlation. The distribution pattern of cold and hot spots discloses the junction of the upper and middle reaches-the junction of the Yangtze River Delta is hot, and the west of upper reaches-the middle and lower reaches are cold. ④The input of agricultural industry is the leading factor affecting the spatial distribution of top agricultural towns in the Yangtze River Economic Belt. The foundation of the agricultural industry is the dominant factor, the output of the agricultural industry is the direct factor, and the location of the agricultural industry is the relevant factor.

Key words: top agricultural towns, spatial distribution, influencing factors, geographic detectors, Yangtze River Economic Belt
