辽宁省冰雪气候资源适宜性评价

Suitability evaluation of ice-snow climate resources in Liaoning province

为充分挖掘辽宁省冰雪资源优势,科学规划开发寒地冰雪资源,利用61个站点的气象数据,采用统计、定性或定量指标等分析方法,评估了辽宁省冰雪气候资源的适宜性。结果表明:辽宁省各地均具有冰雪资源,东部山区冰雪资源最为丰富,辽西地区结冰期长,大连沿海地区冰雪资源相对较少。辽宁省冬季室外冰雪活动温度条件较好,冰雪资源丰富区风速低且日照适中。冬季各地高温融雪、雾和大风、低能见度等气象灾害风险低。11月中旬到翌年3月上旬全省均可人工造雪,人工造雪时段适宜。抚顺、本溪、铁岭、沈阳、丹东、辽阳的大部分地区均是宜冰宜雪的最优地区;西部地区降雪量少,宜冰大于宜雪,可适当开发冰上旅游项目;沿海的葫芦岛和大连地区冰雪期短,可探索发展小规模的冰雪旅游项目和海冰旅游。

In order to fully exploit the advantages of ice-snow resources of Liaoning province,scientifically develop and plan cold region ice-snow resources,the meteorological data of 61 stations were used to evaluate the suitability of ice-snow climate resources in Liaoning province using statistical,qualitative or quantitative indicators and other analytical methods.The results show that ice-snow resources are distributed in all parts of Liaoning province,and are the richest in the eastern mountainous area.The western Liaoning province has less snowfall and a long icing period.Whereas,there are relatively few ice-snow resources in the coastal areas of Dalian.The suitable temperature and sunshine conditions and low wind speed are in favour of the outdoor ice and snow activities in the area with the rich ice-snow resources in winter.The risk of meteorological disasters such as high temperature inducing snow melting,fog,strong wind and low visibility is low in winter.From the mid-November to early March,the artificial snow-making can be conducted in the whole province.Most areas of Fushun,Benxi,Tieling,Shenyang,Dandong,and Liaoyang are the optimal regions for ice-snow tourism and sports in Liaoning province.However,the western Liaoning with less snowfall is more suitable to develop ice tourism relative to snow tourism.Inversely,the coastal areas such as Huludao and Dalian have short ice and snow periods and can be explored in developing small-scale ice-snow and sea-ice tourism projects.
