一、自然概况长白山,以白头山天池为中心,地形由下到上可以明显的分成山前熔岩台地、山前熔岩高原和火山锥体等三个环状地带。其中山前熔岩台地在海拔1000米以下,是长白山山体的最下部分,主要由玄武岩组成,多为起伏的丘陵地带。气候为温带山地针叶混交林气候型,年平均气温在3℃以上,无霜期约100天,植被为针阔叶混交林。山前熔岩高原是长白山高峰和玄武岩台地相联的缓斜地带,海拔1000—2000米,呈环状围绕着火
First, the natural profile Changbai Mountain, Tianchi in Baotou Mountain as the center, the topography from bottom to top can be clearly divided into mountain piedmont lava, piedmont lava plateau and volcanic cones and other three ring-shaped zone. Among them, the piedmont lava stands below 1,000 meters above sea level are the lowermost part of the Changbai Mountain, which are mainly composed of basalt and mostly undulating hilly areas. Climate temperate mountain temperate coniferous forest climate type, the annual average temperature above 3 ℃, frost-free period of about 100 days, the coniferous and broad-leaved forest vegetation. Piedmont lava plateau is the peak of Changbai Mountain and the basalt plateau associated with gentle slope belt, elevation 1000-2000 meters, was ring-shaped around the fire
