摘　　要：基于Python技术获取了梅江区594个旅游资源POI要素点,应用空间点距、核密度、平均最近邻指数及莫兰指数等地理学分析方法对旅游资源点的空间分异特征进行定量分析与地图可视化.结果表明:1)梅江区旅游资源空间分布呈“城镇聚集,乡村分散”的基本特征;2)旅游资源呈“T型”核密度分布结构,由城区向城郊的西北、西南、东南三个方向扩散的圈层体系特征;3)自然景观系空间分布属离散型,基本没有聚集态势且随机性大,主要跟区内的自然山水格局有关;人文景观系核密度核心分级和数量明显较多,高值区呈现3个核心,其中两个核心分布是以中部的城镇、城郊等人口密集区,另一个是城北镇玉水村域,人文景观系与人口密度呈正相关,而且比较聚集.Based on Python technology, 594 POI element points of tourism resources in Meijiang District were obtained. Geographic analysis methods such as spatial dot pitch, kernel density, average nearest neighbor index and Moran index were used to quantitatively analyze the spatial differentiation characteristics of tourism resource points. Map visualization. The results show that: 1) The spatial distribution of tourism resources in Meijiang District presents the basic characteristics of "urban gathering and rural dispersion";2) tourism resources present a "T-shaped" nuclear density distribution structure, from urban areas to the northwest, southwest, and southeast of the suburbs The characteristics of the zonal system of directional diffusion;3) The spatial distribution of the natural landscape system is discrete. There is basically no aggregation and the randomness is large. It is mainly related to the natural landscape pattern in the area;while the core density and the number and number of human landscape systems are obviously There are three cores in highvalue areas, two of which are densely populated areas such as towns and suburbs in the middle, and the other is Yushui Village in Chengbei Town. The human landscape system is positively correlated with population density and is relatively concentrated.
