摘要
本文详尽叙述了新疆干旱区突发性较强的地震、崩塌、滑坡、泥石流灾害以及具牵延性特点的土地沙漠化、盐渍化、水土流失等地质灾害的活动规律和时空分布特征；根据灾害强度，进行了灾害等级区域划分；结合新疆干旱区特点，提出了减轻新疆地质灾害的主要对策和措施。
There are two types cf geological hazards which cause serious damages every year in Xinjiang arid region. One type cutbursts abruptly and the geomorphological processes rapidly, for example, collapse, landslide, debris flow and earthquake; another type changes slowly, but is very serious and the damage is larger, for example, desertification,salinization and soil erosion ect. The former type distributed in middle low-mcuntain area and 70% of this kind of geological lazard concentrited in Tianshan Mountains, but the desertification in Tarim Basin and salinization in Zhunger Basin. The active period of geological hazard is summer, which is closely related to the weather conditions(rainstorm and temperature).The disaster zoning was first divided into three-degree, that is degree 1(serious) hazard zone, degree 2 (in middle), hazard zone and degree 3(weak) hazard zone, according to the intensity of hazard and economic development level of Xinjiang. Geologicel hazard reduction measures in Xinjiang arid region were put forward. The main measures consist engineering measure, biological measure and management measure.
