摘要
文章考证了天然红松(Pinus koraiensis Sieb.et Zucc)及红松林在世界上的地理分布。红松主要分布在中国东北东部、俄罗斯远东南部及朝鲜半岛,日本岛的四国及本州也有零散分布。整个分布区的北界在52°N(俄罗斯);南界在33°50′N(日本);东界在140°20′E(俄罗斯);西北界在49°28′N,126°40′E(中国);西南界在41°20′N,124°E(中国)。红松林的分布以中国东北东部为中心,北到51°N(俄罗斯),南至39°N(朝鲜半岛),森林面积约50万km^2。红松林由南向北随着纬度的递增表现出组成的分异;且随着纬度的递增,红松林垂直分布的海拔高度逐渐下降。人为因素的干扰是导致红松分布范围逐渐缩小的主要因素。
The geographic distribution of Pinus Koraiensis (korean pine) and its forest in the world is reviewed. Korean pine ranges through korean peninsula and east area in northeast China into south part in the Far East region in Russia, with outliers on the Japanese islands of Honshu and Shikoku, and north to 52°N (Russia), south, east, northwest and southwest, 33°50′N (Japan), 140°20′E(Russia), 49°28′N, 126°40′E(China), 41°20′N, 124°E(China), respectively. Korean pine forest ranges from 51°N(Russia) to 39°N (Korean peninsula), with the forest area of 500 thousand square kilometers.From south to the north in its range, korean pine forest has difference in species, elevational distribution decreases gradually. The main factor resulting in reduce of korean pine's range little by little is the disturbance from human being.
