【摘要】：20世纪90年代以来,我国西南边境的一些地区出现了人口不断外流、人烟日渐稀少等现象。此类现象,实际上折射了陆地边境的虚空化。陆地边境虚空化的本质,是以边民为主体的边境常住人口对其传统生存生活空间的疏离。边境地区的人口问题已引起了学界的关注,但现有研究仍不足以全面跟踪观测我国的陆地边境虚空化问题。为弥补现有研究的不足,本文基于1992~2013年的全球夜间灯光遥感数据,对中国西南边境区域与邻国相应区域的人类活动及其变化态势进行了考察并发现:1992~2013年期间,在边境乡镇尺度(10公里纵深),我国西南边境虚空化现象呈持续加剧之势。而在边境县域尺度(50公里纵深),我国西南边境虚空化情况则存在着波动。这充分体现了该数据在观测分析陆地边境虚空化方面的独到优势。不论是从边疆还是国家的整体发展来看,强化边疆地方政府尤其是边疆县一级政府的治理责任,利用好大数据资源并及早防范及治理陆地边境的虚空化,是当前中国陆地边疆治理面临的现实问题之一。
[Abstract]:Since 1990's, some areas along the southwestern border of our country have seen the phenomenon of population outflow and population thinning day by day. Such phenomena, in fact, reflect the empty land border. The essence of the empty land border is the alienation of its traditional living space by the border resident population. The population problem in the border area has attracted much attention, but the existing research is not enough to track and observe the empty land border problem in China. In order to make up for the deficiency of the existing research, this paper, based on the global night lighting remote sensing data from 1992 to 2013, investigates the human activities and their changing trends in the southwestern border region of China and the corresponding regions of neighboring countries, and finds out that the period from 1992 to 2013 is divided into two parts. On the scale of border towns (10 km in depth), the void phenomenon of southwestern border of China is increasing continuously. In the border county scale (50 km depth), there is a fluctuation in the void situation of the southwest border of China. This fully reflects the unique advantages of the data in observing and analyzing the empty land border. No matter from the overall development of the border area or the country, strengthen the management responsibility of the frontier local government, especially the borderland county level government, make good use of the big data resources, and prevent and control the empty land border as soon as possible. It is one of the realistic problems that China's land frontier management faces.
