從五臺山各類景觀要素的分維研究中可以看出，各景觀要素的分維數普遍較低，說明各景觀要素的斑塊形狀較為簡單，受人為干擾較小；分維數較低的有遼東櫟林景觀、溫帶灌叢景觀、溫帶灌草叢及溫帶草原景觀和山地草甸景觀，這說明在該地區與其它植被景觀相比，遼東櫟林景觀、溫帶灌叢景觀、溫帶灌草叢及溫帶草原景觀和山地草甸景觀受人為活動的干擾較小，干擾程度低，天然狀態保持較好。The north slope on the east part of qilian mountains was separated into 6 vertical distribution zones : alpine cold desert meadow 、 alpine meadow 、 alpine bush meadow 、 mountain forest grassland 、 mountain grassland 、 and mountain desert grassland, there are also some areas of alternative distribution
