摘要
利用抛物线模型通过对天山中部、西部冰川槽谷的量算，并对比国内外不同区域的研究成果，发现槽谷抛物线参数Ａ、Ｂ之间具有很强的相关性（｜Ａ｜＝ － ５．４６４＋ ６．１３５·Ｂ），通过其中的任一参数可以描述冰川槽谷的形态，这些参数反映了冰川的动力状况，对冰川地区古气候和古环境的研究具有重要的意义；同时可利用这些参数描述槽谷的不对称性，槽谷的不对称性成因于槽谷两侧的动力差异，主要的影响因素包括：槽谷坡面朝向、冰川交汇。
By measuring 51 glacial valleys in the middle and west of the TianShan Mt. and comparing them with other regions both in China and in other countries, the author considers that the Parabola modal parameters ( A and B ) of the glacial valley have the closed linear relationship and can be described by the formula ｜A｜=-5.464+6.135·B. It is shown that the morphological character of the glacial valley is different in different regions, causing by the difference of the characters of the glaciers. It can be used as the indication of the paleo climate. The asymmetrical character of the glacial valley is formed by the dynamic difference of the glacier on the each side of the valley. The influencing factors include: the direction of the valley side, the function of the glacial convergence, the cornering of the valley and other geological factors.
