摘要
2010年8月7日,甘肃省舟曲县暴发了特大山洪泥石流灾害,给舟曲人民带来了重大的生命和财产损失。通过对甘肃舟曲"8.7"特大山洪泥石流灾害形成原因进行系统的分析,认为特殊的地质地貌条件是灾害发生的潜在原因,突发性强降雨是诱发灾害的动力因素,不合理的人类活动则加剧了灾情的损失和严重程度。在此基础上,提出深入地质灾害基础研究,强化水利水土保持工程建设,退耕还林,注重生态环境保护,规范施工,加快城市基础设施建设,健全灾害监测预警网等防治舟曲及类似地区泥石流灾害的防治对策。
On August 7,2010,an extraordinarily serious flash flood and debris flow disaster occurred which caused great loss of life and property.This paper analyzed its causes,and pointed out that the special geological and geomorphic conditions were the potential reasons,high-intensity rainstorm was the inducing one,and irrational human activities,such as reclamation on steep slopes by cutting trees,building hydroelectric stations without rational measures,and living on landslide body etc.strengthened the disaster.Based on the analysis,some countermeasures for Zhouqu County as well as other similar regions were given.Firstly,deepening studies on geological disaster,and reinforcing building of soil and water conservation measures were quietly required.Secondly,returning land for farming to forest and eco-environmental protection should be paid attention to.Thirdly,canonical constructing hydroelectric stations,road,and the infrastructure in city were needed.Fourthly,sound forecasting and prewarning net system were also required.Furthermore,the measures and the consciousness of preventing debris flow should be publicized among the people that are the base to prevent and control mudflow disaster.
