摘要
新疆的城镇均为绿洲型城镇,大多数分布在山前扇形地上和狭窄的谷地,由于特殊的自然条件决定了绝大数绿洲型城镇都存在着洪水的危害,而泥石流灾害则是洪水灾害中的一个特殊类型。过去,人们对泥石流的研究较少,把不少泥石流灾害都统称为洪水灾害,因而对泥石流灾害缺乏足够的认识,尽管历史上有许多损失十分惨重的泥石流灾害的先例。例如1958年8月13日泥石流将库车县城毁于一旦,使得全城不得不改迁新址。
According to the geologic history, occuring scale, indensity and frequency of the mudflow in Nanshan Mining District, Urumqi, this paper deals with the characteristics of mudflow hazard of the towns in front of mountains or in deep valley. Been based on the characters, three different steps which are (1) avoidance, keeping away from the dangerous region, (2) fight, consolidating the construction and saving the lifes and the properties, (3) control, eliminating or isolating the phenomena, are suggested to minimize the loss for the different situation local social-economics.
