我省东部山区属长白山余脉,从地植物学的观点出发,一般认为现有林地过去绝大部分都是以红松为主的异令复层針闊混交林.即所謂的闊叶红松林。目前在我省东部偏远的高山上腹,还能够偶而看到残留下来的这种林分类型,就是一个明显的例证。在原始林中,这种以红极为主的异令复层針闊混交林,是在一定的地理区内,与該区自然环境条件长期互相作用的结果。这种通过长期的自然选择而适应了其周围环境的植物群落是比较稳定的。它具有保持本植物群落有机体繁荣的内部结构和对外界危害的强大的抵
Mountains in the eastern part of our province belong to the remnants of Changbai Mountain, from the botanical point of view, generally considered the overwhelming majority of the existing woodland in the past are dominated by korean pine mixed coniferous and broadleaf mixed forest, the so-called broad-leaved Korean pine . At present, in the remote mountainous upper reaches of the eastern part of our province, we can occasionally see the type of this remaining forest type. This is an obvious example. In virgin forest, the ecru-clad mixed coniferous and broad-leaved mixed forest dominated by red pole is the result of long-term interaction with the natural environmental conditions in this area in a certain geographical area. This plant community adapted to its surroundings by long-term natural selection is relatively stable. It has a strong internal structure that preserves the thriving organism of the plant community and a strong resistance to the outside world
