引言红松是我国东北地区的珍贵树种,在我国境内的分布最北达小兴安岭北坡的孙吴县(北纬49°20′),南以长白山宽甸县为界(北纬40°45′),东起完达山北坡的饶河县(约东径134°),西止辽宁省本溪市(东径124°45′)。垂直分布于海拔500—1,000m左右。以红松为主的针阔混交林,构成了上述区域的地带性顶极群落。红松材质优良,在国家建设中有着重要地位,因而受到重视。近几十年来,已经在东北等地广泛栽培,红松人工林得到一定的发展。为了进一步研究红松的分布规律与气候特征,
Introduction Pinus koraiensis is a precious tree species in northeastern China. It is distributed in Sunwu County (latitude 49o 20 ’) north of Xiaoxing’an Mountains in China and bounded on the south by the Kuandian County of Changbai Mountain (latitude 40o45’ north) Starting from Raohe County (about 134 ° East Trail) on the northern slope of Wandashan Mountain and Benxi City (124 ° 45 ’East Trail) in the west of Liaoning Province in the west. Vertical distribution at about 500-1,000 m above sea level. The coniferous and broad-leaved forest dominated by Korean pine constitutes the zonal climax community in these areas. The quality of Korean pine has an important position in the national construction and is therefore valued. In recent decades, it has been widely cultivated in Northeast China and other countries, pine plantation has been some development. In order to further study the distribution of Pinus koraiensis and climate characteristics,
