| 摘 要： | 锡林郭勒草原水平带自然地理景观是典型草原和荒漠草原。典型草原最基本的群落类型是大针茅草原和克氏针茅草原，在不同的生境条件下，羊草、冰草、糙隐子草草原类型可成为优势群系。组成荒漠草原群落的建群种和优势种主要是一些强旱生的小型针茅和女蒿、蓍状亚菊等半灌木。至于草甸草原的出现可视为大兴安岭山地植被垂直带的基带，其中羊草草原是基本群系。在地带性景观中可见到隐域性的沙地景观和洼地景观。

| Abstract: | The natural geographic landscapes in Xilinguole steppe are dry steppe and desert steppe. The basic types of dry steppe are Stipa Grandis steppe and Stipa krylovii steppe. In varing site conditions, Aneurolepidium chinense, Agropyron cristatum, Clistogenes squarrosa Steppes may be dominant. The edificatoes and dominant species of consisting desert steppe communities are some small strongly drought-ressistant needlegrass and subshrub such as Hippolytia Trifida, Ajania achillaeoidesa. Some big area non-zonal sand landscape and low land can be seen in the zonal landscapes. The results of fuzzy clustering analysis by using eight climatic factors showed that formation of zonal geographic landscapes was determined by different climatic factors. However, the major factors of forming sand landscape and low land were soil substrate and hydrologic condition respectively. |
