摘　　要：在金沙江干热河谷地区引种黑荆树试验表明,黑荆树适应该区气候和土壤条件,生长良好;而在海拔1200m、1400m和2200m高度坡耕地与荒地生长的黑荆树状况不同,其地径、株高和冠幅存在显著差异,黑荆树在低海拔比高海拔生长良好,在坡耕地比荒地生长良好,表明海拔高度和立地条件对黑荆树生长影响很大,黑荆树作为金沙江干热河谷地区造林和水土保持的先锋树种,其应用前景广阔。Introduction of Acacia mearnsii at elevations from 1200m to 2200m of the dry-hot valley of Jinsha River is aimed at testing its adaptabilities to local environment. The results show that the species suit to dry-hot valley environment and has great potentials as a pioneering tree for afforestation in mid-mountain of this area. The results also indicate that this species grow better at low elevation and on the sites with better conditions.
