诊贵的天然红松林主要分布在我国东北部山区。在长自山地区不但有水平分布,同时还有垂直分布,因长白山海拨高达2700米,而2000米以下为森林植被所覆盖。北坡自上而下,形成亚高山岳桦林、暗针叶林和红松阔叶林三个明显垂直分布带。天然红松林,除主要分布在红松阔叶林外(海拨500—1000米),在暗针叶林下限(海拨1100—1300米)向红松阔叶林过渡的地段,形成红松云冷杉林。因此,天然红松林在长白山沿垂直分布形成红松云冷杉林和红松阔叶林。 天然红松林在长期进化因素作用下,形成一定遗传结构及其功能,本文继分析研究红松阔叶林红松群体酯酶遗传变异之后,仍采用凝胶电泳技术分析研究红松云冷杉林
Diagnosis of natural red pine forests are mainly distributed in the northeastern mountainous areas in China. In Changzishan area not only have horizontal distribution, but also vertical distribution, due to the Changbai Mountain up to 2,700 meters above sea level, and 2,000 meters below the forest vegetation cover. The north slope from top to bottom, the formation of sub-alpine mountain birch, dark coniferous forest and broad-leaved forest three obvious vertical distribution. In addition to the natural Korean pine forest, mainly distributed in the Korean pine broad-leaved forest (500-1000 meters above sea level), dark coniferous forest in the lower limit (1100-1300 meters above sea level) to the Korean pine broad-leaved forest transition section, the formation of Korean pine Spruce Forest Therefore, the natural Korean pine forest in Changbai Mountain along the vertical distribution of the formation of Korean pine and Korean pine broad-leaved forest. After being evolved for a long time by natural factors, the natural korean pine woods formed certain genetic structure and function. After analyzing the genetic variation of the esterase in the Korean pine broad-leaved forest, the electrophoresis technique
