摘要： 基于路阻函数,对栅格成本加权距离法进行了一定的改进,在此基础上,以新疆123个3A级及以上级别景区为例,对其旅游交通可达性进行了测算,并以地州和县级行政单元为单位,研究改进前后两种算法结果的差异。结果显示:改进后,由于加入了运费、交通费和实际车速等因子,使得栅格成本加权距离成本更加贴近地区的自然和社会经济发展状况,弥补了改进前单一考虑设计时速因子所带来的缺陷;改进后可达性的空间分布形态从改进前的西北—东南向的对角线式分布形态,转变为西北—东南向的三级阶梯状分布形态。

Abstract: Tourism transport system is the determinant of tourist destination and its market, it is the basis for optimizing distribution of scenic spots. Accessibility is a potent index and is often used to evaluate the potential ability of region development. Currently, grading approaches of accessibility have been widely used, among them, cumulative time cost grid is most widely used for its intuition and brevity in a practical application. However, the variables of cost function in cumulative time cost grid is too single to reflect the actual accessibility of survey region. To improve the traditional algorithm, a new algorithm has been proposed on the basis of Link Performance Function. In the new algorithm, transportation fees and the actual accessibility was incorporated into the cost function, which has higher reliability to reflect the actual accessibility of survey region. Taking 123 of 3A scenic spots in Xinjiang as the research objects, this article analyzed the spatial distribution of the actual accessibility and compared the two algorithms from the perspective of accessibility. Results shows that new algorithm has higher reliability than traditional algorithm, and it has stronger correlation with the density of road networks than the traditional measurement. The patterns of spatial distribution of accessibility changed from symmetrical triangle to stair-step shape from southeast to northwest of Xinjiang.
