新疆阿尔泰山喀纳斯湖冰层温度变化规律试验研究

2014年12月-2015年4月期间,新疆布尔津县喀纳斯湖举行了冰上旅游项目.为监测冰层生长、发育和融化状况,分别对喀纳斯湖(湖边、湖中)A、B、C三点进行温度监测,利用监测得到的冰层温度数据绘制湖冰从上到下温度分布状况图.根据湖边与湖中的冰层结构特点,从冰层的天然结构角度分析湖冰结构对温度分布的影响.结果表明:天然冰层中温度传递系数并不是一致不变的,既受冰上气温、冰下湖水温度的影响,也受到冰层自身结构状况的影响,并进一步阐述了湖面冰层的温度分布规律与变化成因,为分析温度对冰层强度的影响奠定了基础.

Study of the ice cover temperature variation of the Kanas Lake

An ice tourism project was held in Kanas Lake of Burqin County in the Xinjiang Uygur Autonomous Region in December,2014 to April,2015. To monitor the ice growth,development and melt,ice temperature was monitored on the Kanas Lake(lake front and lake middle),then the lake ice temperature profile variation was obtained. According to the ice structural characteristics in the lakefront and the lake middle,the influence of lake ice structure on the temperature distribution was analyzed. The results show that the thermal transfer coeffi-cient of natural ice is not constant. It is not affected only by air temperature upon the ice and water temperature under the ice cover,but also affected by ice structure. Finally,the temperature distribution and variation of the lake ice are further expounded,which would be useful for analyzing the influence of temperature on the strength of ice.
