摘　　要：基于青海省4A及以上旅游景区和各等级路网交通数据,运用GIS空间分析法、可达性模型、相关性分析,对青海省旅游景区可达性水平、空间格局、造成旅游景区间公路时间可达性差异的因素进行分析。全省旅游景区总体上呈现“区域集中,分散分布”的空间格局,各景区通行时间在2.48 h~11.7 h之间;公路时间可达性格局呈现“强核—弱核”双核空间分布;旅游景区间公路时间可达性与总里程显著性相关,与高速公路里程高度相关,与国道里程中度相关,与省道里程相关不明显。Based on the traffic data of 4 A and above tourist scenic spots and various levels of road networks in Qinghai Province, GIS spatial analysis, accessibility model and correlation analysis are applied to analyze the accessibility level of tourist scenic spots in Qinghai Province, spatial pattern and the factors that cause the difference in road time accessibility among tourist scenic spots. The overall spatial pattern of tourist scenic spots in the province is “regionally concentrated and scattered distributed”, with the travel time to each scenic places ranging from 2.48 h to 11.7 h.The pattern of highway time accessibility presents a dual-core spatial distribution of “strong core—weak core”, and the highway time accessibility between tourist attractions is significantly related to the total mileage: highly related to expressway mileage, moderately related to national highway mileage, and not obviously related to provincial highway mileage.
