基于全域自驾游可达性的青海省旅游空间结构研究

随着“全域旅游”时代的来临，居民旅游出行模式与旅游空间结构都发生了深刻的改变，推动“交通模式—旅游结构”的互动发展变得日益重要.通过研究青海省106个A级景点和43个自驾车营地的空间分布特征和交通可达性，分析县域等时圈内自驾车营地与A级景点的协调程度，划分不同等级协调性区域，进而采用空间关联方法来分析青海省旅游空间格局.研究表明：①青海省旅游空间结构以西宁市为核心集聚分布，景点和营地分布空间格局演变的方向逐渐向南部和西部发展，沿交通网高核密度区形成旅游廊道，全省A级景点的平均可达性时间为2.47 h，自驾车营地平均可达性时间为3.35 h；②自驾车营地与A级景点的耦合协调性与可达性程度呈现区域一致性，中低可达性区域的耦合协调性较低；③自驾车营地和A级景点可达性呈较强空间集聚格局，冷热点区以西宁市区为兔形之首呈现中心—外围结构，由核心热点区逐渐过度到外围冷点区，推进自驾车营地建设向南部和西部通道扩散.为了增强全域自驾旅游可达性，提升青海省旅游空间结构的协调程度，应注重中低可达性区域自驾车营地分期规划建设.

Study on the tourism spatial structure of Qinghai Province based on the accessibility of all-area self-driving tourism

A better coordination between scenic spots and self-driving camps at the county level is significant for tourism development. In this paper， 106 A-level scenic spots and 43 self-driving camps are included to measure the accessibility of scenic spots and spatial distribution feature by self-driving transport in Qinghai's tourism market. The result shows as follows. 1) The Qinghai tourism spatial structure presents a concentrated distribution pattern， with Xining city as the nodal point of the tourism corridor. The spatial distribution pattern of scenic spots and campsites is evolving toward the south and west. The average access time of A-level scenic spots and self-driving camp is 2.47 h and 3.35 h， respectively. 2) The degree of coupling coordination and accessibility of self-driving camps is consistent with that of A-level scenic spots， while that of medium and low accessibility area is relatively low. 3) The self-driving camp and A-level scenic spots are highly clustered in the core cities of Qinghai such as Xining and surroundings. In order to enhance the accessibility of tourist attractions based on self-driving and to reshape the tourism spatial structure of Qinghai province， more investments should be secured to construct self-drive camps in low accessible regions.
