摘　　要：本文以若尔盖县582个地质旅游资源点为研究对象,运用GIS空间分析法探讨其空间分布特征及其影响因素。结果表明:(1)若尔盖县地质旅游资源分为4个主类,12个亚类和39个基本类型,优良级旅游共104个,在主类中均有分布;(2)若尔盖县地质旅游资源的空间分布类型属于聚集分布,在乡镇尺度上分布不均衡;空间分布密度呈现“北部多,西南部边缘少,中部多”的分布特征;地质旅游资源分布线性特征明显,具有公路指向性和河流依赖性;(3)地形地貌、植被覆盖度、地质构造、地层岩性和人口经济等因素是影响若尔盖县地质旅游资源分布的重要因素。研究结果将有利于对若尔盖县地质旅游资源的保护和开发,能更好地提升若尔盖县地质旅游产业发展。Zoige county is rich in geological tourism resources,and there are different geological landscapes in different regions.In order to promote the rapid and healthy development of geological tourism,the spatial distribution and influencing factors of geological tourism resources in Zoige county are studied.In this paper,it taken akin 582 geological tourism resource points in Zoige county as the research object,used ArcGIS spatial analysis method to explore the correlation between its spatial distribution characteristics and influencing factors such as topography,slope and aspect,geological structure,stratigraphic lithology,vegetation coverage,population economy and so on.The results show that:(1)The geological tourism resources in Zoige county are divided into 4 main categories,12 subcategories and 39 basic types.There are 104 excellent tourism resources,which are distributed in all the main categories;(2)The spatial distribution type of geological tourism resources in Zoige County belongs to the aggregation distribution,and the distribution is not balanced at the township scale.The spatial distribution density shows the distribution characteristics of‘more in the north,less in the southwest edge and more in the middle’.The distribution of geological tourism resources in Zoige county has obvious linear characteristics,with highway directivity and river dependence;(3)Topography,geological structure and population economy are the main influencing factors of geological tourism resources in Zoige county.The research results will be conducive to the protection and development of geological tourism resources in Zoige Ccounty,and can better improve the development of geological tourism industry in Zoige county.
