摘要
本文利用乌鲁木齐河源1号冰川物质平衡量实测资料、天山大西沟温度与降水、乌鲁木齐地温资料,讨论了该冰川物质平衡与某些气候要素的关系:7月气温、夏季5-7月降水及3-4月地温是控制当年物质平衡量的主要气象要素;通过寻找最佳因子,利用多元线性回归方法,建立了该冰川年物质平衡量的预报公式,同时讨论了资料插补问题。
Through analysis on the measured data of annual mass balance of Glacier No.1 at thesource of Urumqi river, monthly mean air temperature and precipitation observed at Daxigometerological station in Tianshan Mountains and monthly mean soil temperature at Urumqi,the relationship between the mass balance and climatic variables is carefully discussed. It isfound that air temperature in July, precipitation during May-July and soil temperature dur-ing Mar. -Apr. are the major controls of the connual mass balance in a mass balance year.By way of seeking the optimum meterological factors influencing the annual mass balanceand using multivariate linear stepwise regression analysis, a mass balance prediction equationis presented, and a interpolation equation is obtained depending only on factors in the lasttwo mass balance year. The missing mass balance data in 1958/1959, 1966/1967-1978/1979 have been interpolated.
