中文摘要：

以中国科协办公厅评审认定的2010—2014年度、2012—2016年度及2015—2019年度全国科普教育基地为研究对象,借助谷地地理信息系统获得每个基地的地理坐标,利用ArcGIS10.2对中国科普旅游资源时空分异特征进行综合分析。结果表明：中国科普旅游资源空间分布属于集聚性分布类型,但分布均匀度较低,体现出较强的不均衡性,主要集中在上海,北京,山东,江苏,广东等省级行政区,其他省级行政区数量较少,西藏自治区最少;核心（边缘状分布格局明显,以上海为中心的华东地区和以北京为中心的华北地区为主要集聚区（数量之和占全国总量的一半以上）。3个年度中国科普旅游资源总量和各地理分区科普旅游资源数量都经历了先减少又增多的变化,表现出中国科普旅游资源发展的非均质性;3个年度均以中东部地区为主要分布区域,尤以华东地区和华北地区最为集中;度量地理分布平均中心始终落在河南省境内,向东北方向小幅度偏移,空间分布方向性不是特别明显,离散程度较高。

英文摘要：

This paper takes the national popular science education base in 2010-2014,2012-2016 and 2015-2019 as the object of study and uses the GoodyGIS and ArcGIS to make a comprehensive analysis on the temporal and spatial differentiation of Chinese popular science tourism resources. The results show that：Spatial distribution of Chinese popular science tourism resources belongs to the type of agglomeration distribution, but the distribution uniformity is low. It shows strong imbalance, with provinces such as Shanghai, Beijing, Shandong, Jiangsu,Guangdong being of higher density, and other provinces having less and Tibet Autonomous Region being the least. The core-periphery distribution pattern is obvious, with Shanghai and Beijing as the main gathering area, the center of East China and the center of North China respectively. The total amount of tourism resources and the number in each geographical area experienced first decrease and then increase, which shows the heterogeneity of development of popular science tourism resources in China. The Chinese popular science tourism resources in different years mainly distribute in the eastern region,especially in East China and North China. The average distribution centers are always in Henan Province and slightly shift to the northeast direction. The spatial distribution of direction is not particularly obvious with a higher degree of dispersion.
