摘　　要：以东非狼尾草为研究对象,调查了云南省种羊繁育推广中心人工草地植被群落和生产性能的生态稳定性。结果表明,东非狼尾草为当地气候条件下抗逆性和竞争性较强的栽培牧草品种,群落稳定性和生态适应性优于其它人工牧草。该草具有侵占取代恶性杂草群落;空间场地地绿化;维持草地生态与生物产量稳定性等重要作用。The objective of this study was Pennisetum clandestinum. The vegetation community and the ecological stability in production performance of the artificial grassland were investigated at the breeding sheep popularize centre of Yunnan province. The results showed Penniseturn clandestinum was a cultural variety of pasture that had better stress resistance and contention character under local climate condition, and the vegetation stability and ecological adaptaion character was superior to other artificial pastures. It played an important role in replacing the malignant weeds, virescence of space and field and maintaining the stability of grassland ecosystem and biological production.
