| 摘 要： | 西藏贡嘎机场周边因沙源丰富，造成每年的1-5月扬沙满天，严重影响了飞机正常的起降和周边居民的生产、生活乃至生存。经实地调查和气象、水文资料的收集，以及对沙漠化影响因子相关性分析，提出机场周边地区土地沙化和风沙灾害的成因是自然因素和人为因素综合作用的结果，人为因素中的耕地面积、土地垦殖率因子和自然因素中的大风日数因子是风沙灾害形成的主导因子。 |
| 关 键 词： | 贡嘎机场 风沙 沙化土地 成因 |

| Abstract: | There were rich sand resources in the areas of Gongga airport of Tibet, which resulted in the sandstorm from January to May every year and had serious influences of airplane takeoff and touchdown, and yield and living of local people. Based on the field investigation, collection of meteorological and hydrological data in the local, and correlation analysis of many factors led to desertification, the causes of desertification and sandstorm formation in the airport areas were proposed by the integrated effects of natural and human factors. The results showed that the key factors led to desertification and disastrous sandstorms in local area were respectively arable area, reclamation rate of wasteland and days of gale. |
| Keywords: | Gongga airport sandstorm desertification causes of sandstorm formation |
