抗战大后方侵华日军无差别轰炸重大惨案的时空分布考察

抗战时期，侵华日军为了彻底摧毁中国政府和人民抗战的意志和决心，对大后方实施了惨绝人寰的空中杀戮，制造了死亡100人以上或死伤500人以上的重大惨案共达86次。这些惨案在时空分布上呈相对集中的鲜明特征。具体来看，在时序分布上，惨案集中在抗战相持阶段，1940年达到最高峰。另外，因为地形和天气的影响，夏季是惨案的高发期。在空间格局上，惨案集中在四川、重庆战略核心地区；水路、铁路和公路等交通干线所在区域是重灾区；县级及其以上城市最为惨重。这种时空分布格局彰显了侵华日军企图通过制造重大惨案，造成恐怖气氛，达到动摇抗战大后方民众意志，迫使国民政府妥协屈服，实现占领和殖民中国的目的。

Temporal and Spatial Distribution of Serious Tragedies Caused by Japanese Indiscriminate Bombing in the Home Front of the War of Resistance Against Japanese Invasion

During the War of Resistance Against Japanese Invasion, to completely destroy the resistance determination of Chinese government and people, Japanese army carried out deadly aerial killings in the home front, and caused 86 serious tragedies with more than 100 deaths or 500 casualties each time. These tragedies were characterized by relatively concentrated temporal and spatial distribution. Specifically, as for temporal distribution, most tragedies happened in the stalemate stage of the war, peaking in 1940. Additionally, under the influence of topography and weather, most of the tragedies happened in summer. In terms of spatial distribution, the tragedies centralized in the strategic core area, such as Sichuan and Chongqing, and mainly distributed along waterways, railways and highways. They mainly distributed in county or higher levels. The distribution shows that the Japanese tried to make terrible atmosphere by creating serious tragedies to shake the people''s determination in the home front and to force the national government to surrender, so that they could achieve their purpose of occupying and colonizing China.
