在我的收藏中,有几百张日军侵华时期印制的中国军用地图。这些地图上往往清楚地标明“中华民国某年某月印制,昭和某年复制”,在一些具有重要战略意义的地区,日军还派出飞机对民国地图进行空中修测,这类图的附注中就标明哪个区域使用着原图,哪个区域是经过修测的。早在1931年9·18事变之前,日本人就对中国东北、华北和华中地区的资源、文化、兵要地志进行了相当详尽的调查了解。但是,1937年日军侵华之时显然掌握着成套的中国军用地图,这些精确的大比例尺军用地图,在日军侵华之前 In my collection, there are hundreds of Chinese military maps printed by the Japanese invaders during the invasion of China. These maps are often clearly marked “Republic of China printed in a year, Showa a copy of the year”, in some strategically important areas, the Japanese army also sent an aerial map of the Republic of China aerial repair, such drawings in the note Indicate which area uses the original image and which area is under test. As early as the 9.18 Incident of 1931, the Japanese conducted a rather detailed investigation and understanding of the resources, culture and military affairs of the northeast, north and central regions of China. However, when the Japanese invaded China in 1937 apparently had a complete set of Chinese military maps, these accurate large-scale military maps were taken before the Japanese invasion of China
