| 中文摘要: |
| 忻州市东北部为山西省典型沟谷泥石流的高易发区,具有发生频次高、形成时间集中、破坏性大的特点,对当地人们的生命财产安全造成极大威胁,因此对该区域的泥石流进行风险管控是开展地质灾害防治工作的重要基础,而泥石流风险评价则是其核心工作之一。为了更好地开展区域地质灾害风险管控,分析明确单条泥石流的风险性,研究选取忻州市东北部21条典型沟谷泥石流分别开展单沟风险评价和区域风险评价,首先选取合理的评价指标通过层次分析法(AHP)计算各条泥石流的单体风险性,再与利用GIS方法得到的泥石流区域风险评价成果对比,综合确定风险程度,并对不同等级的风险区和风险点进行分类,在此基础上提出合理的"隐患点+风险区"双管控风险建议,为当地政府部门开展风险管控及防灾减灾提供参考。 |
| 英文摘要: |
| The northeast area of Xinzhou city is a high risk area of mudflow in Shanxi province. The mudflow here takes place in high frequency and concentrates in time interval and leads to serious destruction thus threatens the local people’s life and property. Risk assessment and management of the mudflow is the basis for prevention and reduction of geological disaster. Risk of each mudflow is analyzed to manage and control regional geological disaster. 21 typical valley mudflow in the northeast area of Xinzhou city are selected for single mudflow and regional risk assessment. AHP method is used to pick up the assessment specification and calculate risk of each mudflow then the result is compared with the regional mudflow risk assessment made by GIS method. The Risk degree is integratedly determined. The risk areas and points are divided into different scales. Based on the mentioned above "hidden risk point+risk area" the dual management and control policy is suggested to the local government for reference. |
