| 摘 要： | 构建沙区道路风沙灾害危险性评价的指标体系对区域道路风沙灾害防治重点区的划定及减灾对策的制定有着重要意义。文中以区域灾害系统理论为依据,通过分析灾害形成过程中致灾因子、孕灾环境、承灾体三者的作用机制,提出孕灾环境对灾害形成存在直接和间接两种作用的思想;在分析道路风沙灾害形成机制的基础之上,建立了科尔沁沙地道路风沙灾害危险性评价的指标体系并进行评价。结果表明:轻度危险路段417km,中偏轻度危险路段657km,中度危险路段798km,中偏重度危险路段453km,重度危险路段150km,极度危险路段30km。

| Abstract: | Establishing the hazard assessment index system of blow sand disaster on roads in sandy lands takes an important part in demarcating the key areas of preventing roads from blow sand disaster and developing countermeasures for mitigating the disaster.Based on the theory of regional disaster system,by analyzing the relationships between Hazard-formation factors,Hazard-formation environments,and Hazard-affected bodies,three basic viewpoints were brought forward.Firstly,Hazard-formation factors and Hazard-affec... |
