环境是影响军事活动的重要因素之一,尤其是军事技术比较落后的古代,这种影响就更加明显。南宋与金在淮南地区的战争中,金军作为外来者,其在淮南地区的军事活动,受到环境因素的制约更为明显。而这种影响对于南宋来说又是有利条件之一,他可以最大限度地利用环境,结合传统的军事战略战术,从而在战争中掌握主动,进而保卫淮南地区的安全。 The environment is one of the important factors that affect military activities. In particular, the influence of the military technology is still relatively backward in ancient times. Southern Song Dynasty and Jin in the war in Huainan, the Jin army as an outsider, its military activities in Huainan area, subject to environmental constraints more obvious.
