摘　　要：城市内部的旅游景点可达性在一定程度上反应了城市交通的发展水平。本文以贵阳市中心城区旅游景点为样本,借助ArcGis软件工具,利用网络分析方法,以两个时段两种交通方式分别分析了居住小区至旅游景点的平均可达性及其空间分布特征。结果表明:(1)贵阳市中心城区居住小区的平均可达范围在空间上差异显著,呈现出"中心好—外围差"的不规则面状分布;(2)在非高峰时期,贵阳市中心城区私人小汽车交通与常规公共交通可达时间的平均值大约相差20min,而在高峰时期,二者相差近15min;(3)从两个时段两种交通方式来看,南明区的居住小区平均可达性都最好,云岩区排在第二,乌当区、观山湖区、花溪区和白云区分别位居其后,可达性最差的为研究区域的西北角与西南角落。在上述分析的基础上,探讨了贵阳市中心城区交通存在的问题及其原因,并提出了优化建议。The accessibility of tourist attractions within the city,to a certain extent,reflects the development level of urban traffic.Tourist attraction in the center area of Guiyang city is taken as the research sample in this paper.We have considered two traffic modes during two different periods to analyze the average reachability which from residential area to tourist attraction and its spatial distribution characteristics by the ArcGis software and the network analysis method.The results show that:(1)For the residential area in which the central urban area of Guiyang,its average reachability range is significantly different in space,that is,showing the irregular distribution of"Center is well– Periphery is bad".(2)The average value difference of the reachable time between the private car traffic and the conventional public traffic is about20min in the central urban area of Guiyang during the off-peak period.While for the peak period,the difference is nearly15min.(3)From the point of the two traffic modes during two different periods,the average reachability of the residential area in Nanming district is the best,Yunyan district rank second,then the following are respectively of Wudang district,Guanshan lake district,Huaxi district and Baiyun district.The worst reachability is the northwest corner and the southwest corner among this study’s areas.The existing traffic problems in the center area of Guiyang city and the reasons have been discussed based on the above analysis in this paper.Moreover,we also put forward the optimization suggestions.
