秦岭是我国主要的山地之一,是长江和黄河两大水系的分水岭。秦岭以南属亚热带气候,自然条件为南方型;以北属暖温带气候,自然条件为北方型。秦岭南北的农业生产特点也有显著的差异。因此,长期以来把秦岭看作是我国“南方”和“北方”的地理分界线。 Qinling is one of the main mountains in China and is a watershed between the two major river systems of the Yangtze River and the Yellow River. South of the Qinling Mountains is a subtropical climate, the natural conditions for the southern type; north is warm temperate climate, natural conditions for the northern type. There are also significant differences in the features of agricultural production between north and south of Qinling Mountains. Therefore, Qinling has long been regarded as the geographical dividing line between China’s “South” and “North”.
