| 摘 要： | 毛乌素沙地的高等植物共有1106种，分属于98科420属。主要的科有菊科、禾本科、豆科、蔷薇科、藜科。主要的属有蒿属、黄芪属、葱属、柳属、杨属，主要的种有沙蒿、沙竹、牛心朴子、沙柳、乌柳。植物群落类型有草原植被、草原和荒漠灌丛、沙生植被、草甸植被、盐生植被、沼泽和沼泽性植被、水生植被，其中沙生植被占主导地位，其次为草甸植被。植物群落主要有沙蒿群落、沙蒿一柠条群落和沙柳、乌柳、沙棘组成的“柳湾”。简述了毛乌素沙地的植被分布特征，提出该区植被建设应以灌木为主，采取灌、乔、草相结合等措施。 |

| Abstract: | There are 1 106 species of high vegetation in Maowusu sandy land and they belong to 98 families and 420 genuses.The main families are Compositae,Gramineae,Leguminosae,Rosaceae,Chenopodiaceae; the main genuses are Artemisia,Astragalus,Allium,Salix,Populus;and the main species are Artemisa ordosica,Psammochloa villosa,Pycnostelma lateriflorum,Salix cheilophila,Salix microstachya. There are 7 types of vegetation communities in this region.They are grassland vegetation,grassland and desert shrubbery,sandy vegetation,meadow vegetation,halophyte vegetation,marsh and swamp vegetation.Among these vegetations,sandy vegetation is the dominant vegetation;meadow vegetation is the second vegetation.The main communities are Form.Artemisia ordosica, Form.Artemisia ordosica Caragana korshinskii, Form.Salix microstachya, Form.Salix cheilophila S.microstachya, Form.Hippophae rhamnoides Salix cheilophila. The vegetation distributing characteristics has been briefly stated.Shrubberies should be the chief vegetation for vegetation construction in Maowusu sandy land,shrubberies, arbores and grasses should be combined with other measurements. |
| Keywords: | Maowusu sandy land vegetation resource community type distributing characteristics protection measurements |
