摘要
在前苏联中天山进行了两年的野外调查研究,利用所得资料,建立一个计算亚大陆型山地冰川物质-能量交换和冰川径流的模型。找出了控制这一地区现代冰川作用的主要冰川气候因素并使之定量化。计算了这一地区冰川在全球水文循环中的作用以及输入这一封闭水系的水气,即贮存在这一地区的水分占大气总水汽通量的份额。发现全球大气循环变化同冰川作用的相互影响。此外,重建了这一地区冰川300年来物质平衡各分量。
A model for calculating the mass-energy exchange and glacial runoff from sub-continental mountain glacier systems was developed using the experimental data from two years of field investigation in the Central Tien Shan of the former Soviet Union. The primary glacioclimatic factors controlling the current state of glaciation in this system were identified and quantified. The effect of this glacial system on the global hydrological cycle and share of the total atmospheric moisture input to this blind drainage system that is stored in the system were calculated. The interaction of the global atmosphere circulation change and state of glaciation was found. The components of mass balance of this glacial system for the last 300 years was also reconstructed.
