摘　　要：蒿与蒿类半灌木植物是天然草地资源中饲用价值高、分布广、数量多的一类重要牧草。在我国约９属３３５种，占全国草地饲用植物总数的５．２７％，其中蒿属近２３０种、绢蒿属３４种，在生态型上多为旱生和超旱生种类。主要分布在内蒙、新疆、西藏、宁夏、甘肃、青海等省区草原及荒漠草地中，面积４７７６．１９万ｈｍ２，约占全国草地总面积的１２．１６％，占六省区草地总面积的１７．３４％。主要以建群种和优势种构成草原及荒漠类型，且具重要饲用价值。笔者就蒿类半灌木植物的分布、地位、饲用价值、特点、生态功能等方面进行了较详细的论述。Sagebrush is one of major components with high feeding value and wide distribution in native pasture. There are 335 species belonging to 9 genus. It is composed 5.27% of the total forage plants in China, among them, there are 230 species belonging to Artemisia and 34 species belonging to Seriphidium. These species are drought or super-drought resistant as far as biological type concerns. These species are mainly distributed in the pasture and desert pasture of Inner Mongolia, Xinjiang, Tibet, Ningxia, Gansu and Qinghai provinces with total area around 47 761 900 hectares. It is composed 12.16% of the total native pasture in China and 17.34% of the total pasture in above 6 provinces. These species are major or dominant species in pasture and desert with high feeding value. The distribution, status, feeding characteristics and value of sagebrush were described in this paper.
