摘　　要：在闽南沿海山地开展尾赤桉(9224)、雷林1号桉(SH1)、尾巨桉(EC4)和莫氏1号(M1)4个桉树无性系栽培试验,通过连续4 a的生长性状、适应性、抗风性以及生长潜力的观测与分析,结果表明:EC4速生性、适应性强,3.5年生林分平均树高、胸径达13.23 m和13.04 cm,且有一定的抗风能力,林相整齐,自然整枝能力强,生长潜力大,在闽南沿海山地可进一步推广应用;9224的速生性和生长潜力比EC4略差,但其适应性、抗风性以及生长潜力均较强,在闽南沿海山地也是一个可值得推广的品种;M1速生性较强但生长潜力小、抗风性差,在闽南沿海山地不提倡推广;SH1速生性很一般,生长潜力也小,但抗风性强,在闽南沿海台风多发区域可有选择地作为培育纸浆原料林应用。This object of study was E. urophylla × E. camaldulensis（ 9224 ） ,Eucalyptus leizhouensis NO. 1, M1 and E. urophylla× E. grandis （ EC4 ）. Through continuing for four years, the results showed the E. urophylla x E. grandis （ EC4 ）had an advantage in the comparison of growth properties and had a good ability in resist tropical storm, 3.5 - year - old stand average tree height and dbh reached 13.23 m and 13.04 cm,it might be expanded in the Southern Fujian;the next one was E. urophylla x E. camaldulensis （9224）. M1 had small growth potential and strong wind -resist ability, but the M1 was not worth expanding in cultivated area. SH1 might be planted in the area where typhoon was happening with increasing frequency, and could be selected for culturing pulp raw material forest.
