选取江苏省41场马拉松认证赛事为研究样本，运用最邻近点指数、地理集中指数、地理联系率、核密度指数等方法研究马拉松认证赛事的分布规律及影响因素。结果表明：①江苏省马拉松认证赛事整体空间分布趋于集聚，空间结构属于凝聚型；②不同类型马拉松认证赛事中，半程马拉松认证赛事集聚程度高，全程马拉松、16公里、10公里和5公里马拉松认证赛事布局分散；③经济基础、教育程度、景点资源和产业发展是影响特马拉松认证赛事分布的主要因素。

Select 41 marathon certification events in Jiangsu Province as research samples, and use the nearest neighbor index, geographic concentration index, geographic connection rate, nuclear density index and other methods to study the distribution rules and influencing factors of marathon certification events. The results show that: ① The overall spatial distribution of marathon certification events in Jiangsu Province tends to be concentrated, and the spatial structure belongs to the condensed type; ② Among the different types of marathon certification events, half-marathon certification events are highly concentrated, and the whole marathon, 16km, 10km and 5km marathon certification events are scattered in layout; ③ Economic foundation, educational level, scenic spot resources and industrial base are the main factors that affect the distribution of the marathon certification events.
