摘  要：
为达到复壮林分、减轻红缘天牛危害的目的,对不同坡向、不同坡位的沙棘进行平茬试验,平茬后留茬高度分-5 cm、0 cm、5 cm和10 cm 4个处理。试验结果表明,平茬对当年沙棘生长有一定的影响,平茬后植株的冠幅等显著减小;不同留茬高度间沙棘的生长仅有较小的差异;平茬能有效地降低红缘天牛的数量,减轻其对沙棘的危害,但不同留茬高度之间无显著差别;坡向和坡位及其交互作用对红缘天牛的为害没有显著影响,对沙棘的生长有一定的影响,阳坡坡中和坡下及阴坡坡中的沙棘生长状况较好。

摘  要：
In order to rejuvenate Hippophae rhamnoidea forest stand and reduce the damage of Asias halodendri Pallas,Hippophae rhamnoidea plants were treated with four stubble heights at-5cm,0cm,5cm and 10 cm after stumping. The results showed that: effect of stumping on the growth of H. rhamnoidea in the current year was apparently,crown breadth decreased significantly; the growth of H. rhamnoidea under different stubble height only had small differences. Stumping could reduce the populations of A. halodendri Pallas and its damage efficiently,but the effect of different stubble height was not significant. The effects of slope aspect,slope location and interaction between them on damage of A. halodendri Pallas were not significant,but effected the growth of H. rhamnoidea,the H. rhamnoidea individuals grew better at the middle or lower south faced slope and middle north faced slope.
