【摘要】 本文将灰色关联分析理论引入冰川学研究的领域。应用该理论对乌鲁木齐河源１号冰川东、西支冰川平衡线与气候因子之间的关系进行了研究，结果表明，夏季（６－８月）平均气温是影响平衡线波动的主导气候因子；平衡年度内不同时期降水量的变化对于冰川平衡线波动的影响程度具有差异性。更多还原

【Abstract】 Abstract In the paper，the theory of grey relational analysis is introduced into the domain ofglaciological study．Analysed the relations between climatic factors and the equilibrium linesof east and west branches of Glacier No. 1 in the headwaters of the Urumqi River in theTlanshan Mountains by means of the theory，it is found that summer mean air temperature isthe leading climatic factor which dominates the fluctuation of the equilibrium line，and thereexist disparities in the influences of precipitations during different periods in a balance yearon the changes of the equilibrium line.
