摘要: 本文对我国第四纪冰期气候和环境进行了综合定量分析,澄清了冰期雪线的概念,研究了现代和冰期气候雪线的变化规律,认为冰期对中国北部和东部均属非冰川区的冰缘环境。

Abstract: Both topographic snow line and climatic snow line are the highest line of snow cover in extremely high temperature in summer, not the product of extremely low temperature climate in winter. Through the comprehensive and quantitative analysis of the climate and environment in the glacial period in China, it is considered that the eastern and northern parts of China in the Quaternary belonged to the periglacial environment in non-glacial zones, There was no cold trough in the middle and lower reaches of the Changjiang River, And the mountain height never went beyond the upper limit of forest line.
