武漢市主城區(qū)餐飲業(yè)空間特征及與動(dòng)態(tài)人口的耦合分析

摘要： 城市餐飲業(yè)空間格局研究對(duì)城市規(guī)劃及城市可持續(xù)發(fā)展具有重要意義.針對(duì)現(xiàn)有研究中方法單調(diào),衍生研究以對(duì)影響因素定性分析為主的不足,采用POI數(shù)據(jù),運(yùn)用基于核密度的熱點(diǎn)指數(shù)方法對(duì)武漢市主城區(qū)的餐飲熱點(diǎn)進(jìn)行識(shí)別,并結(jié)合工作日和休息日的百度地圖熱力圖數(shù)據(jù)構(gòu)建人口活動(dòng)強(qiáng)度模型,對(duì)動(dòng)態(tài)人口與餐飲業(yè)空間分布進(jìn)行耦合分析.分析發(fā)現(xiàn),武漢市主城區(qū)餐飲業(yè)可顯著識(shí)別出1個(gè)一級(jí)中心、3個(gè)二級(jí)中心和9個(gè)三級(jí)中心;餐飲業(yè)分布與動(dòng)態(tài)人口的空間匹配程度總體較好,工作日時(shí)匹配程度高的區(qū)域占比稍高于休息日.匹配程度為較差和差的區(qū)域依具體類型不同而散布在大型商圈外圍、傳統(tǒng)中小型商圈、旅游點(diǎn)、復(fù)興街區(qū)和新興街區(qū).
The research on spatial pattern of urban catering industry is of great importance for urban planning and urban sustainable development.This paper focuses on the simplicity of the existing research methods and insufficiency on the qualitative analysis of influencing factors in the derivative studies.Coupling analysis between dynamic population and the spatial distribution of the catering industry is carried out through identifying the hot spots of catering in the main city of Wuhan using POI data and the hot spot index method based on nuclear density,and establishing the model of population activity intensity by combining the heat map of weekday with weekend from Baidu Map.The analysis shows that there are 1 primary center,3 secondary centers and 9 tertiary centers of the catering industry in the Wuhan main city.The spatial distribution of catering industry generally matches the dynamic population with the matching degree of weekday slightly higher than that of weekend The regions with poor and even worse matching degree are scattered on the periphery of the large-scale commercial circles,the traditional small and medium-sized shopping districts,tourist spots,renewed blocks and emerging blocks depending on their specific types.
