中国地理信息科学专业点的空间分异

Spatial Differentiation of China's Geographic Information Science Discipline

以地级以上城市为基本统计单元,分析了2015年地理信息科学本科、硕士、博士专业点的空间分布,并在省域单元上与2005年数据进行对比,根据每百万人专业点数量的基尼系数测度了地理信息科学专业点的区域差异.研究表明,我国地级以上城市地理信息科学专业点密集分布在东部和中部地区,整体上从东到西逐渐减少,南北方向上则主要集中在北京至成都纬度带中.从省域单元看,我国地理信息科学本科专业点的区域差异相对合理,且呈现出明显的均衡化特征;硕士专业点尽管覆盖广泛,但仍有较大的区域差异;博士专业点则短期内仍将呈现出区域上集中的分布态势.

In this paper, taking prefecture-level cities as the basic statistical unit, the spatial distributionof undergraduate, master and doctor discipline of Geographic Information Science in 2015 was analyzed.Compared with 2005, the regional differences of Geographic Information Science in the provincialunit were measured according to the G coefficient of the number of discipline per million people. Studyshows that, China,s prefecture-level Geographic Information Science disciplines densely distribute in theeastern and central regions, and decrease from east to west as a whole. In north-south direction, GeographicInformation Science disciplines are mainly concentrated in latitude band of Beijing to Chengdu.From the provincial unit, the regional differences in China＇s Geographic Information Science disciplinesare relatively reasonable, and showing a significant equalization feature. Despite the widespread mastercoverage, there are still large regional differences. In the short term , the doctor will continue to show acentralized distribution situation.
