制约乌鲁木齐河源1号冰川消长诸因子初探
|
摘要
本文利用乌鲁木齐河源１号冰川年物质平衡资料和天山大西沟及其周围台站温度与降水、乌鲁木齐地温、地球自转、ＥｌＮｉｎｏ、天山南北地震等资料，讨论了该冰川物质平衡与诸因子变化的关系：地球自转的减慢、ＥｌＮｉｎｏ的出现、南天山地震的发生与正的物质平衡相一致；以大西沟站为基点，计算其温度、降水与周围台站的相关系数，发现大西沟与三大盆地的相关性不好，特别是降水表现为负相关，因此不能用盆地测站的资料来推断天山深处的气候变化。
Through analysis on the data of annual mass balance of Glacier No 1 at the source of rümqi River, monthly mean air temperature and precipitation data observed at Daxigou meteorological station in Tianshan Mountains and its surrounding, monthly mean soil temperature data at Urumqi, earth rotation velocity,El Nino,earthquakes happened in the south and the north of Tianshan Mountains,the relationship between the mass balance and controlling factors are carefully discussed. It is shows that the decelerating of earth rotation velocity,the happening of El Nino and earthquakes happened in the south of Tianshan Mountains are corresponded with positive mass balance; the correlation coefficients of air temperature and precipitation between Daxigou and its surrounding stations are calculated and analysed, and they are lowest between Daxigou and three basins,especially precipitation presents nagative correlation,therefore the climatic variation in the inside of Tianshan can′t be infered by using the data of three basins.
