摘要
基于皖南国际文化旅游示范区综合交通路网络,利用GIS空间分析中成本距离算法,选取平均旅行时间和可达性系数指标,对示范区五星级农家乐空间可达性格局进行研究。结果表明:示范区农家乐空间布局呈现"大分散,小集聚"圈层结构。依据缓冲区范围内的农家乐个数,将其空间布局归纳为"交通依赖型"、"景区辐射型"、"都市边缘型"3类;示范区内的农家乐平均旅行时间都在3h以内,平均用时1.794h,综合交通网络较发达。但可达性系数极差达到0.964,可达性空间分布不均衡现象突出,内部差异显著;可达性空间格局表现为以农家乐为核心的距离衰减规律且交通网络指向性特征明显。农家乐空间分布和交通路网结构是影响可达性的关键因素。
Based on comprehensive traffic network of international cultural tourism demonstration area in the south of Anhui province, we applied cost distance algorithm of GIS space analysis, the index of weighted average travel time and accessibility coefficient to analyze the accessibility pattern of agritain- ment spots in the demonstration area. Results revealed, the space layout of agritainment spots presen- ted the ＂overall decentralization, small cluster＂ pattern. According to the number of agritainment spots in the buffer area, the spatial layout of the farm was divided into three types ： ＂traffic-oriented＂, ＂sce- nic spot-radiation＂ and ＂urban fringe＂. The average transit time of all agritainment spots were less than 3 hours, the average time was 1. 794h. But, the range of accessibility index was 0. 964. The ac- cessibility spatial distribution was imbalance, and the internal difference was obvious. The spatial pat- tern of accessibility was characterized by the distance attenuation circle with the core of agritainment spots and with strong traffic orientation. The distribution of agritainment spots and road network con- struction was the most critical factor for the above spatial pattern of accessibility.
