摘要: 在对1993年5月5日宁蒙两区发生特大沙暴考察的基础上,系统分析了特大沙暴形成的原因、造成的危害及沙暴的运行规律。结果表明,特大沙暴发生是在大气候条件控制下,由大风、干旱和土地严重沙漠化不断扩大的综合作用结果,这次特大沙暴给人民生命财产造成了极为惨重的损失。沙暴运行规律表明,防护林和治沙工程对防止沙暴的作用是十分显著的。同时针对沙暴易发区的自然、社会和经济特点,提出了预防、整治和合理开发利用该区资源的综合防治对策。

关键词: 沙暴, 灾害沙漠化, 防治对策

Abstract: Based on the investigation of extraordinarily serious sand storm(ESSS) occurred on May 5th, 1993 in Ningxia Hui Nationality and Nei Monggol Autonomous Regions, the formation cause of this ESSS, its disastrous harms and moving patterns are analyzed. The results show that its occurrence is the comprehensive results of gale, aridity and desertification under the effect of macroclimates, and the losses or harms caused by it are very disastrous, Its moving patterns indicate that establishing shelterbelts or windbreaks and sand control engineering can prevent ESSSand avoid its harms. In view of the natural, social and economic characteristics of areas vulnerable to sand storm, the comprehensive strategies of preventing sand storm, managing desert and utilizing and developing sand land resources are put forward.

Key words: Sand storm, Calamity, Desertification, Preventing strategy
