摘　　要：运用可达性方法定量研究井冈山风景区公路网络空间结构,考虑地形、道路等级、拥挤度等因素对车速的影响,采用加权平均旅行时间评价指标,分析不同旅游季节景点可达性和对外可达性变化。研究表明:1井冈山风景区景点可达性和对外可达性分别呈现"中心—外围"摄动变形的圈层结构与"东—西"摄动变形的圈层结构,可达性空间分布遵循空间距离衰减性、交通指向性、高等级路网指向性等。2旅游季节因素对可达性影响显著,旅游旺季可达性水平发生明显变化,可达性空间分布也受其影响。3路网结构、景点布局和节点规模是影响可达性分布的重要因子。在此基础上,提出了可达性优化建议。This paper uses the accessibility analysis method to research the spatial structure of Jinggangshan scenic region, and take the factors which have important influence on speed, such as terrain, grade of road and congestion into consideration. Then we use the index of weighted average travel time to analysis the accessibility of road way out and the accessibility of scenic spots at different tourism season. The research results are as follows： Firstly, the accessibility of scenic spots presents the ＂Center- Periphery＂ pattern; the accessibility of road way out presents the ＂East- West＂ pattern.And they all follow the features of spatial attenuation, traffic directional and high-grade road directional. Secondly, tourist season has significant influence on the level of the accessibility. In tourist season, the accessibility changes obviously.Lastly, the highway network structure, the distribution of scenic spots and the scale of node are the important factors affect the level of accessibility. Based on the results, we propose some recommendations to improve the level of accessibility.
