The results show that after the surface cracks appeared, the number of bacteria and actinomyces in the rhizosphere of A. ordosica is reduced, the number of fungi and the activity of enzyme are increased, the amounts of water content and electric conductivity are decreased, therefore the interferences of surface cracks on the biological activity in the rhizosphere of A. ordosica are quite obvious. After more than a year, with surface cracks gradually close, the content of soil water gradually returned to the normal, the effects of surface cracks on phosphatase activity, sucrase activity, and electric conductivity are gradually weakened, while the effect of surface cracks on the number of microorganisms does not change obviously. Nevertheless, the biological activity in the rhizosphere of A. ordosica possesses certain self-repair ability; however the complete recovery of biological activity might take a longer time.,

地表裂缝对油蒿根际的生物活性造成明显的干扰破坏.经过一年多的时间, 随着地表裂缝的逐渐闭合, 油蒿根际土壤含水量恢复正常, 电导率、蔗糖酶活性和磷酸酶活性受地表裂缝的影响逐渐减弱, 而微生物数量受地表裂缝的影响未见明显好转.可见, 油蒿根际的生物活性具有一定的自修复能力, 但进程比较缓慢., authors=杜涛, 毕银丽, authorsList=杜涛;毕银丽,
