长白山系我国名山之一,位于亚洲大陆东岸,频临太平洋;为松花江鸭绿江及图们江的发源地;这里蕴藏着丰富的动、植物资源;现为我国的最大自然保护区。在我国水平地带性植被区划中,长白山属于温带针阔叶混交林带,其地貌、气候、土壤及植被等自然条件,常因海拔不同而呈明显变异,因此,被科学家们自下而上地划分为四个不同的自然景观带:①针阔混交林景观带(海拔为600—1000米);②针叶林景观带(海拔1,000—1,800米);③高山岳桦林景观带(海拔1,800—2,000米);④高 Changbai Mountain, one of China’s famous mountains, is located on the east coast of the Asian continent, frequenting the Pacific Ocean. It is the birthplace of the Songhua River and the Tumen River. It contains abundant animal and plant resources and is now China’s largest nature reserve. In China’s zonal zonation zonation, Changbai Mountain belongs to the temperate coniferous and broad-leaved mixed forest belt. Its natural conditions like geomorphology, climate, soil and vegetation often show obvious variation due to different elevation. Therefore, scientists are divided from bottom to top For four different natural landscape belt: ① coniferous and broad mixed forest landscape belt (elevation of 600-1000 meters); ② coniferous forest landscape belt (1,000-1,800 meters above sea level); ③ alpine landscape of birch forest (elevation 1,800- 2,000 meters); ④ high
