摘要
运用旅游景点可达性方法来定量地研究城市旅游空间结构,开发基于最短时间路径选择算法的旅游景点可达性计算与分析信息系统,基于南京市区的公路路网结构,对南京市区旅游景点可达性做了实证研究,生成了景点可达性的分值扩散图、时间等值线图、旅游景点服务范围图和以乡镇为基本计算单元的景点可达性图。通过对生成图表的分析,笔者发现:南京市区旅游景点整体可达性较好,80.59%的区域景点可达性在40min之内,但其内部差异也比较明显,中心主城区景点可达性较好,外围地区特别是边界地区景点可达性较差,最差地区为103min39s,通过对乡镇为基本计算单元的整体景点可达性的等级分析,发现南京市区景点可达性在地域分布上呈现以主城区为中心的圈层空间结构。在上述分析的基础上,将南京市区分为主城区、近郊区、远郊区三个区域,根据三个地区各自特点制定了相应的景点可达性优化目标,并给出了优化措施。
The study of the spatial structure of city tourism is receiving increasing attention but methodology so far has used qualitative rather than quantitative methods.This paper applies an accessibility and analysis information system based on calculations of optimal road routes and times to scenic spots in Nanjing.This enabled the construction of time contour,diffusion and service range maps and diagrams.The study found that over 80% of the region had access to Nanjing＇s scenic spots in less than 40 minutes.However,downtown scenic spots were found to be much more accessible than those on the periphery of the city.At county level,accessibility to the city＇s downtown scenic spots shows a concentric pattern.Due to the disparities in intra-regional accessibility,the paper suggests the development of scenic spots in a recreational belt around the city to optimize their spatial distribution,particularly in Liuhe,Pukou,and Jiangning districts.
