甘肃省旅游资源丰富,有3个5A级和15个4A级景区,但是由于受交通条件和经济因素的影响,旅游经济并不是十分发达。本文将城市地理学的腹地理论应用于旅游规划中,同时考虑中心城市旅游经济综合规模和公路交通条件,在GIS软件支持下,采用矢量数据的空间分析方法,以2009年甘肃省14个地级市州为研究对象,借助场强模型和哈夫模型,计算旅游经济的场强,进行城市旅游腹地的测定,发现场强随着距离中心城市和路网越远而逐渐减小,并且腹地多形成于中心城市周边,沿路网分布十分明显。然后将旅游腹地与市域行政区范围进行叠置分析,找出属于处于相同层次类型的城市,以期为增加全省旅游经济收入,全省城市旅游经济区划和旅游规划编制提供参考。
Gansu Province is rich in tourism resources and has 3 5A and 15 4A-level scenic spots. However, due to the traffic conditions and economic factors, the tourism economy is not very developed. In this paper, the theory of the hinterland of urban geography is applied to tourism planning. At the same time, taking into account the comprehensive scale of tourism economy and the traffic conditions in the central city, spatial analysis of vector data is carried out with the support of GIS software. City and state as the research object. With the help of the field strength model and the Hough model, the field strength of tourism economy is calculated and the tourism hinterland of the city is measured. The field strength decreases with the distance from the central city and the road network, Formed around the center of the city, distribution along the road network is very obvious. And then the tourism hinterland and city area administrative area overlay analysis to find belong to the same level of type of city, in order to increase the province’s tourism economic income, the province’s urban tourism economic zoning and tourism planning provide a reference.
