中文摘要	汶川8级地震直接引发了大量的崩塌、滑坡等次生灾害,为泥石流提供了丰富的物质来源,在经历过2008年雨季后,激发了一定数量的泥石流,在今后5~10 a的时期内,还将激发大量的泥石流。震后岷江上游泥石流今后的发展趋势,主要取决于是否产生暴雨以及暴雨笼罩范围,地震引发的崩塌、滑坡是否堵塞沟道与泥石流发生、发展也有密切关系。地震后,岷江上游的泥石流防治也将面临着严峻的形势。通过对岷江上游典型泥石流沟防治工程现状的统计,指出了目前防治工程存在着数量少、标准低、承灾能力差、结构单一、设计不合理等问题,在此基础上,提出了岷江上游的泥石流灾害防治原则。
英文摘要	TheWenchuan Earthquake triggered large numbers of secondary disasters such as landslip and landslide. After the 2008 rainy season, large numbers of debris flow with large scale were triggered. So, the p revention of debris flow in the earthquake area will be faced with many new p roblems. The geology, topography and climate conditions in the up river ofMinjiang are favorable to the formation of debris flow. The debris flow of this area is well developed in the history. Based on the field investigation, there are 404 debris flow gullies in the up river of Minjiang. Large numbers of landslip s and landslides, which triggered by theWenchuan Earthquake, p rovide abun2 dantmaterials for debris flow’s formation. In the next five to ten years, the damage of debris flow in this area will be more serious. The developmental tendency of debris flow in the up river of Minjiang mainly depends on the whether rainstorm is formed, whether the earthquake area is included in the rainstorm and whether channels are blocked by landslip s or landslide. After the Wenchuan Earthquake, the p revention situation of debris flow in the up river ofMinjiangwill be serious. In this paper, the p revention p rojects of typ ical debris flow gullies in the up river ofMinjiang are collected. Then, main p roblems of the p revention p rojects ( such as small quantity, low standard, low p reventing ability, simp le structure and irrational design) are summarized. At last, the p rincip les of debris flow’s p revention in the up river ofMinjiang are put forward.
