【摘要】 小吃是餐饮业的重要组成部分,其空间格局分布会直接影响居民和游客的行为决策。选取北京市中心城区范围内的沙县小吃和成都小吃网点为研究对象,以小吃网点POI数据和GIS空间数据作为数据源,运用GIS空间分析、核密度估算等方法,对北京中心城区的沙县小吃和成都小吃网点的空间分布特征进行了比较分析,结果表明,小吃网点的空间分布特征为:各区的分布差异较大;两类小吃网点在各圈层分布差异较小;道路环线小吃网点分布由中心向外围呈"金字塔型";小吃网点分布的道路邻近性强于地铁邻近性。小吃网点的集聚特征为:小吃网点空间集聚呈现弱向心性分布;小吃网点空间集聚特征显著,内部结构差异较大。根据以上研究结论,结合市政规划,按城区分类,对北京中心城区小吃网点的分布提出建议:重组旧城区小吃网点;按城区功能定位重新规划分布新城区小吃网点。更多还原

【Abstract】 Snacks are an important part of the catering industry,whose spatial pattern distribution will directly affect the behavior of residents and tourists decision-making. Therefore,this paper chooses Shaxian snacks and Chengdu snack outlets in the center of Beijing city as the research objects,taking POI data and GIS spatial data as data sources,using GIS spatial analysis and nuclear density estimation method,to make a comparative analysis of the spatial distribution characteristics of snack outlets in Beijing central city. The results show that the spatial distribution characteristics of snack outlets include: 1) the distribution of snacks in different districts is different;2) the difference between two kinds of snack outlets in the circle distribution is small; 3) road ring snack network distribution from the center to the periphery is "pyramid type"; 4) snack network distribution of road proximity is stronger than subway proximity. The gathering characteristics of Snack outlets inclue: 1) snack network spaceconcentration showed weak centripetal distribution; 2) snack network space collection characteristics show a significant difference between the internal structures. According to the above conclusions, combined with municipal planning,this paper,according to the classification of the districts,puts forward some suggestions on the distribution of snack outlets in Beijing: 1) to recombine the old city snack outlets; 2) to redistribute the new city snack outlets according to the city function positioning.更多还原
