休闲旅游业作为推动城镇化高质量发展的重要力量，对城市转型升级和内涵式发展发挥着重要作用。相较于大城市，中小城市休闲旅游业的发展需求更为迫切。以宿迁市为例，综合采用核密度分析、空间相关性分析、标准差椭圆算法分析等空间分析方法，对宿迁市的休闲旅游空间格局进行研究。结果表明：(1)休闲旅游业整体呈现北密南疏的“一中心三节点”空间分布格局，各类休闲旅游业在中心城区和各市辖县均形成不同规模的聚集，并沿省道、县道两侧分布；(2)各类休闲旅游业在空间分布上的相关性较强，其中餐饮类和购物类的空间相关性最高，购物类和风景类的空间相关性最低；(3)各类休闲旅游业标准差椭圆整体皆呈“东北-西南”走向，且中心点较为接近。最后，为优化宿迁市休闲旅游格局提出建议。

As an important component of modern urbanization, leisure tourism industry plays a significant role in urban transformation, upgrading, and connotation development. Compared to big cities, the development demands for leisure tourism industry in medium and small cities are more urgent. Taking Suqian City for example, we comprehensively adopted GIS spatial analysis methods such as kernel density analysis, spatial correlation analysis, and standard deviation ellipse to investigate the spatial pattern of leisure tourism industry. The results show that(1)the leisure tourism industry shows the characteristics of a spatial distribution pattern of “one center and three nodes” with denser facilities in the north and sparser in the south. All kinds of leisure tourism have formed different scales of clusters in the central urban area and each county, spreading outward along provincial roads and county roads.(2)There is a strong spatial correlation among all kinds of leisure tourism, with the highest correlation between catering and shopping services, and the lowest correlation between shopping services and scenic spots.(3)The standard deviation ellipses of all kinds of leisure tourism generally trend in the “northeast-southwest” direction, and the central points are relatively close. Finally, we proposed suggestions to optimize the spatial pattern of leisure tourism industry in Suqian City.
