高速公路影响下的广西旅游景区可达性格局研究

On the Layout of the Accessibility of Tourist Attractions in Guangxi Facilitated by Expressways

文章根据旅游景区可达性模型,结合使用Arc GIS网络分析与地统计分析方法,以广西壮族自治区4A及以上景区为研究对象,分析广西旅游景区在有无高速公路条件参与下的可达性水平变化及空间分布格局演变,总结出高速公路网对广西旅游景区可达性格局影响的一般规律,加入高速公路分析要素之后,景区平均通行时间由5.033h减少到3.945h,景区可达性系数在0~0.3范围内的从38个上升为65个,广西旅游景区可达性格局圈层分布的总体形状没有改变,但是中心极核有向北移动趋势。最后,提出广西旅游空间结构优化建议。

Taking scenic spots on or above 4A level in Guangxi as its subject, this paper analyzes their accessi- bility level change and space distribution pattern evolution with and without expressway participation based on accessibility model for tourism scenic spots, ArcGIS network analysis and statistical analysis. The general rules of the accessibility pattern of Guangxi tourism attractions are then obtained, The findings suggest that their av- erage access time decreases from 5. 033 hours to 3. 945 hours, that the number of accessible scenic spots in- creases from 38 to 65 when accessibility coefficient is in the range of 0 - 0.3, and that the overall layers distri- bution shape does not change with the core shifting northward. The paper concludes with optimization proposals for Guangxi＇s tourism spatial structure.
