摘要:

利用1961—2020年辽宁省61个国家级地面气象观测站资料, 分析了辽宁省适宜滑雪场地建设和滑雪运动的气象条件特征及长期变化趋势。结果表明: 辽宁省中部、北部和东部年结冰日数(日最高气温小于0 ℃)大于60 d, 符合高等级滑雪场建设的气温标准, 其中辽宁中东部年平均降雪量超过20 mm, 积雪深度超过10 cm, 为辽宁省最适宜建设滑雪场地区; 综合分析风力、温度和降雪量级日数等对滑雪运动影响最显著的气象因子, 发现滑雪气象指数2级以上日数辽宁省中东部最多, 超过120 d, 是辽宁省最适宜开展滑雪运动的地区。其中抚顺市在发展滑雪项目上有很大优势, 有利于承办全国冬季运动会雪上项目比赛。滑雪气象条件的长期趋势变化表明, 年结冰日数明显减少, 年降雪量和年最大积雪深度略减少, 最适宜建设滑雪场的区域减小; 而滑雪气象指数2级以上日数增加了12.2 d, 适宜开展滑雪运动的区域向西扩大, 气象条件更加有利于滑雪运动的开展。与气温和风速相关的气象指标为滑雪气象条件长期趋势变化的主要因素。辽宁省中东部在具备有利的气象条件同时, 还有地形、经济、交通等方面优势, 为发展高品质冰雪运动文旅产业提供良好的基础。

Abstract:

Based on the data of 61 national surface meteorological observation stations in Liaoning province from 1961 to 2020, the characteristics and long-term trend of meteorological conditions suitable for ski resort construction and ski sports were analyzed.The results showed that the annual number of freezing days (with a daily maximum air temperature of less than 0 ℃) in the central, northern and eastern parts of Liaoning province is more than 60 d, which meets the temperature standard for the construction of high-level ski resorts.The annual average snowfall in the central and eastern parts of Liaoning province exceeds 20 mm, and the snow depth exceeds 10 cm, which is the most suitable area for the construction of ski resorts in Liaoning province.Through comprehensive analysis of meteorological factors that have the most significant impacts on skiing, such as wind force, temperature, and snowfall days, it is found that the number of days with a ski meteorological index above level 2 is the highest in the central and eastern regions of Liaoning province, exceeding 120 d.These areas are the most suitable areas for skiing sports in Liaoning province.Among them, the Fushun area has great advantages in the development of skiing events, which is conducive to hosting the snow events of the National Winter Games.The long-term trends of skiing meteorological conditions show that the number of freezing days has decreased significantly, the annual snowfall and annual maximum snow depth have slightly decreased, and the most suitable areas for ski resorts have decreased.While the number of days with a skiing meteorological index above level 2 has increased 12.2 d, the area suitable for skiing is expanding westward, and the meteorological conditions are more conducive to the development of skiing.Meteorological indicators related to temperature and wind speed are the main factors for the long-term trend of skiing meteorological conditions.Meanwhile, the central and eastern regions of Liaoning province have favorable meteorological conditions and have advantages in terrain, economy, transportation, etc., which will provide a good foundation for the development of high-quality ice and snow sports, and cultural tourism industries.
