阿尔泰山地横亘于亚洲中部,地跨中、哈、俄、蒙四国。中国是它的最南端。在生物区系演化中,由于北方类群入侵,并与亚洲中部适温寒型荒漠类群在域内汇合并相互渗透,这里生物多样性组成十分独特,资源高度富集,并形成了完整的自然景观垂直带谱结构,即北极苔原、欧洲一西伯利亚泰加林、北方森林草原以至亚洲中部荒漠等垂直地带 Altai mountains lie in the middle of Asia, across the ground, Kazakhstan, Russia, Mongolia four countries. China is its southernmost point. In the evolution of biota, due to the invasion of northern groups and its convergence with and interpenetration with the moderate warm-cold desert groups in central Asia, the biological diversity here is very unique and highly resource-rich, forming a complete vertical landscape of natural landscapes The band structure, namely, the Arctic tundra, a European Siberia Tegucallin, the northern forest grasslands and the Central Asian desert and other vertical areas
