摘　　要：中国沙棘是中国干旱荒漠区退化生态系统恢复与重建的重要树种。为了给沙棘北种南引提供参考,笔者首次将中国沙棘引入中国亚热带低海拔地区,通过引种栽培,设置2个试验地,采用2种埋深处理,对试验地和埋深处理之间的成活率指标进行双因素固定效应模型检验,并结合气象因子变化情况分析处理对沙棘成活率的影响。结果表明,地形因素及埋深因素主要通过对不同环境因子的重新配置,以对沙棘的成活率发生影响,浅埋较之深埋种植具有更高的成活率。成活率从生长季之初的高于60%显著下降到14%～25%,但仍然有沙棘的植株个体在试验区内成活。Chinese sea buckthorn is an important tree species for the restoration and reconstruction of degraded ecosystems around China ＇ s arid zones.In order to provide references for introducing Chinese sea buckthorn from the north to the south of China,by breeding introduction and setting two trial sites and burial depth,the survival rate and influence mechanism were analyzed by fixed effect model testing.Topographic factors and burial depth produced effects on survival rate by reconfiguring of different environmental factors.The survival rate of shallowly buried seedlings was larger than that of deeply buried ones.Although the survival rate decreased from more than 60% at the early growth season to 14%-25% at the end of growing season,there were some plant individuals of Chinese sea buckthorn survived.
