Abstract: With the rapid development of China's national economy and people's living standards continuing to improve,the tourism has been prospering as well. As the three pillar industries of tourism,lodging industry has become the most basic facility for providing the most basic services for tourists. Exploring the spatial distribution of lodging industry in the city area is very essential for planning the lodging industries. According to China Hotel Association's report,nearly 90% of users will check users' reviews before booking decisions,online booking of hotels has become a leading option for Chinese travelers seeking the best deals and convenience. Qunar.com,a mainland online travel information provider,is the world's most popular Chinese travel platform,and provides Location Based services(LBS). With the data from Qunar.com,and by adopting four spatial analysis methods,including vector data symbolization,nuclear density analysis,exploratory spatial data analysis(ESDA) and Kriging spatial interpolations,this paper analyzed the spatial distribution characteristics of lodging industry of Urumqi City,Xinjiang,China in 2015,from aspects of scale grades,density,degree of concentration,hot zones and their spatial patterns. The results show as follows:(1) The southern and the inner Urumqi were high-density areas,and the northern and the outer parts were low-density areas. The lodging venues distributed in ellipse with Children Park as the center. The spatial distribution of different types of lodging venues were broadly in line with the overall spatial characteristics,but showed some specificity.(2) The lodging industry mainly distributed in patch,belt, and planar,and around important traffic infrastructure(railway station,airport),CBD,sports centers,convention centers,administration centers,etc. Different types of lodging industry had different spatial distribution types. (3) High-high areas were continuously located in the traditional habitations and urban-industry flouring areas in the south of Urumqi; while the low-low areas were dispersed in urban fringe areas,which mainly located in the north and southwest of Urumqi.(4) Four spatial aggregated hot zones of lodging industry were built with spatial interpolation analysis. Based on comprehensive analysis of regional hardware and software conditions,these hot zones were identified into four patterns:traditional rail transit hot zone in traditional urban center,business and recreation hot zone based on CBD,technology and business hot zone based on aggregated new technological industry, and airport hub hot zone based on Urumqi International Airport. Conclusions of this study will be helpful to explore location laws and distribution of lodging industry from spatial perspective,and could provide references for rational distribution and planning of lodging industries in practice,which is also beneficial to promote the development of tourism in Urumqi. Results also show that information from internet combing with geospatial information can not only affect the way tourists travel and live,but also provide new ways for urban internal spatial structure studies.
