| 摘 要： | 在造林试验基础上,总结出半荒漠风沙区优良沙生灌木树种柠条、毛条、杨柴、花棒、沙木蓼造林的最佳季节是春季;造林后的第2、3年是各种灌木株高和地径生长量的高峰阶段,第4年以后,株高和地径的生长量均下降,并有枝条枯死现象,应该平茬更新,平茬最佳年龄均为4 a生.试验结果表明,杨柴群落是半荒漠风沙区流动和半流动沙地立地上较稳定的人工固沙植物群落,柠条群落是半荒漠风沙区半固定和固定沙地以及干滩地较稳定的人工固沙植物群落. |

| Abstract: | This experiment summarized that spring is the best season for the platation of shrubs that are good at growing in insemi-desert area,such as Caragana microphylla,C.korshinskii,Hedysorm leave,H.scoparium,Atraphaxis bracteata,surveying showed that plant height and ground diameter growth of various shrubs reach peak in 2~3 a; plant height and ground diameter growth of various shrubs decreased withered in 4 a.So up to 4 a,biomass above ground should be harvest.The results of plantation showed that the community of Hedysorm leave was very stable in shifting and semishifting sandy land of semi-desert area; the community of Caragana microphylla was comparatively stable in halff-ixed,fixed sandy and water-dried land. |
| Keywords: | Semi-desert area Excellent desert shrub species Afforestation technology Community stability |
