侵华日军中苏边境防线是日本关东军用十余年的时间苦心构筑和经营的,是现代战争史上最长的防线。由于这项军事工程规模大,保存下来的资料又少,因此,对其中有些筑垒地域的研究还没有进行或者还不够深入。本文首次介绍了法别拉筑垒地域的研究情况和海拉尔筑垒地域的进一步研究成果。 The invasion of China and the Soviet border by Japanese troops is Japan’s Gantan military building and operating with more than a decade of hard work and is the longest defensive line in the history of modern warfare. Because of the large scale of this military project and the paucity of information it has preserved, studies on some of these areas have not been conducted or are not sufficiently advanced. This article firstly introduces the research situation of Fabira region and further research results of Hailar region.
