大兴安岭象一条巨蟒横卧在祖国东北地区的西北角,南部最高峰阿尔山太平岭为1,712米,北部高峰奥库里堆山为1,520米,中部高峰大白山为1,404米。整个山体长达1,400公里,东西宽300公里,宽度由北向南缩小。大兴安岭自然保护区象一块闪闪发光的宝石,镶嵌在这绵绵山岭北部。这是我国最大保护区,主要分两片,一片在呼玛河及金河的河源,面积33.3万公顷;一片在大兴安岭南坡诺敏河中游,面积约为14.9万公顷。大兴安岭一年中大部分时间被冰雪覆盖,自古以来称为我国的“北极”。整个山体呈北北东—南南西走向,使东南季风前进受阻,西伯利亚吹来的高压气流也在这里受到削弱,因而山地南坡与北坡气候迥然不同。
Daxinganling like a python lying in the northwestern corner of the northeast of the motherland, the southern peak of the Taier Ridge Arles is 1,712 meters, the northern peak of the Ocuri Hill is 1,520 meters, the central peak of the White Cliff 1,404 meters. The entire mountain is 1,400 km wide and 300 km wide and widened from north to south. Daxinganling Nature Reserve, like a glittering gem, inlaid in this rolling mountain north. This is the largest protected area in our country. It is mainly divided into two sections, one in Heyuan of the Huma River and the Golden River and covers an area of 333,000 hectares. The middle reaches of the Noble River in the southern slope of the Greater Xing’an Mountains cover an area of about 149,000 hectares. Daxinganling most of the year covered by snow and ice, since ancient times called China’s “North Pole.” The entire mountain body runs north, north, east, south, west and west, blocking the advancement of the southeast monsoon. The high-pressure air blown by Siberia is also weakened here. Therefore, the climate on the southern slope and the northern slope of the mountain is very different.
