摘要： 应用天山编目1051组粒雪线资料,经过数据转化处理,将离散性样点归并为规则的网格分布,进一步插值加密提高拟合程度,绘制出与实际资料相吻合的粒雪线变化趋势图.从图中可以看出,天山粒雪线趋势主要有以下几个特征:(1)趋势面脊线(主轴线)纬向延仲;(2)趋势面高程变化经向大于纬向;(3)经向变化中速率最大的是汗腾格里山;(4)趋势面的最高点在托木尔峰南坡,最低点在巩乃斯河谷上游。

Abstract: Using the data of snow grains line from Glacier Inventory of the Tianshan Mountains, group 1051, by processing the data, incorporating the scattered samples into regular grip distribution, and further interpolation as to promote the fitting degree, we prepared the trend surfate map of snow grains line which coincides with the practical data, from the map it may be seen several features of snow grains line of the Tianshan Mountains：①Ridge line of the trend surface stretches along the direction of latitude. ②Longitudinal variration of altitude greater than that of latitudinal direction. ③Maximum longitudinal variation rate occurs at the Hantengeli Mountain. And. ④highest point of the trend surface locates at south slope of the Tuomuer Peak and the lowest in the upper reaches of Gongnaisi River Valley.
