| 中文摘要: |
| 第24届冬季奥林匹克运动会将于2022年在北京、张家口举行，因此监测和分析当地积雪时空变化特征对筹备冬奥会相关工作具有重要意义。本文选用气象观测资料， AVHRR、MODIS、SMMR/SSMI/SSMIS等遥感数据反演的积雪参数，以及区域气候模式的模拟预测结果来分析冬季积雪的时空变化特征及其对冬奥会的潜在影响。结果表明冬季积雪面积、深度、覆盖频率和积雪日数均呈现微弱增加趋势。张家口的积雪资源优于北京，“延庆 张家口市区 崇礼”方向积雪深度等参数高于周围地区，冬奥会比赛场地的布设比较科学、合理。但是各项积雪指标均处于较低水平，年际波动大，积雪稳定性差。而且未来2月份的气温呈上升趋势，降水反而呈减少趋势，这将进一步降低积雪的稳定性，对冬奥会有一定的负面影响。因此，需要做好人工造雪的准备，以保证充足的雪量和冬奥会赛事的正常举办。 |

| The 24th Winter Olympic Games will be held in Beijing-Zhangjiakou area in 2022. Therefore, monitoring and analyzing the spatial and temporal changes of local snow cover is of great significance for the preparation of the Winter Olympics Games. In this paper, the meteorological observation data and the AVHRR, MODIS, SMMR/SSMI/SSMIS data are used to analyze the temporal and spatial variation characteristics of winter snow cover in Jing-Zhang area and its potential impact on the Winter Olympics Games. The results show that the snow cover area, depth, coverage frequency and days with snow cover show a slight increase trend. The snow cover resources in Zhangjiakou are better than those in Beijing. The parameters such as the depth of snow along the line-Yanqing-Zhangjiakou City-Chongli are higher than the surrounding areas. The layout of the Winter Olympic Games venues is scientific and reasonable. However, all the snow cover indicators are at a low level, with large inter-annual fluctuations and poor snow stability. Moreover, the temperature in February will increase, and the precipitation will decrease. This will further reduce the stability of snow and have a certain negative impact on Winter Olympics Games. Therefore, it is necessary to prepare for artificial snow making to ensure sufficient snow and the normal holding of the Winter Olympic Games. |
