摘　　要：嵩草属(KobresiaWilld.)植物是多年生草本植物,主要分布于中国青藏高原,多数是高寒草甸的建群种,具有草质柔软、营养丰富等特点,为各类家畜所喜食,是青藏高原主要的优良牧草和生态草种,其良好生长对维持青藏高原的生态平衡有重要作用.介绍了近年来对嵩草属植物的系统位置、地理分布、生长土壤、繁殖对策以及生理生态等的研究概况,对研究前景作了展望.Kobresia species distribute mainly in the Qinghai-Tibet plateau of China. All Kobresia species are perennial herb that most of Kobresia species are the dominant species in the alpine-meadow. Kobresia species are very important fine pasture and ecological grass in the Qinghai-Tibet plateau. There are a lot of crude protein and fat in them. All livestock prefer them. In addition, Kobresia meadow is important in retaining the ecological environment of Qinghai-Tibet plateau. The main research achievements on Kobresia species in recent years are introduced in the fields of the systemic location, geographic distribution, soil characteristics, reproductive strategy and physiological ecology, et al. Some considerations for future researches of Kobresia species are prospected.
