摘　　要：为解决鸟害隐患,提高机场飞行安全,2004年6月,在昆明巫家坝机场草坪上选择1.5 hm2样地,分为5个试验区域建植东非狼尾草草坪;旋耕,整地,分别以株、行距均为20、40、60、80 cm的密度扦插东非狼尾草。结果表明,80 cm的行、株距是最经济的扦插密度;东非狼尾草(Pennisetum clandestinum)具有良好的竞争力。对建植的东非狼尾草草坪连续6年的观察发现,该草坪建植成本低,当年即可成为免维护的草坪;草层低、密,无鸟类食源,鸟害隐患大幅下降;常年绿色;通过东非狼尾草草坪上空传过来的噪音,分贝数比原有草坪低15.7%。因此认为,东非狼尾草是昆明机场草坪的首选草种。To improve the airport flight safety and remove the hidden danger of birdstrike,1.5 ha native lawn at Kunming Wujiaba airport was used to establish Pennisetum clandestinum lawn.The native law was preparated by Disc plough and divided into 5 experimental plots,in which P.clandestinum cuttage were planted with four densities（20,40,60 and 80 cm row and individual plant spaces）.The results showed that the most economic density was 80 cm row and individual plant space.P.clandestinum exhibited well competition with the native species at the airport.The P.clandestinum lawn became no-maintenance lawn at the first established year and cost lower for continual 6 years at Kunmibg Wujiaba airport.The hidden danger of birdstrike was largely reduced because of bird food absent,lower and denser grass layer.The decibel sound through the P.clandestinum lawn was also significant reduced by 15.7% compared to the native lawn（P0.01）.It was suggested that P.clandestinum was the top choice pasture species to establish maintenance free lawn of Kunming Wujiaba airport.
