本文根据古植被、古动物的间接标志以及冰缘现象等直接标志为依据,认为把我国晚更新世多年冻土南界划到北纬39—40°最为合适。进入全新世中国北方的气候出现过明显的波动和干湿变化,在高温期时气温较现在高1—2℃,在小冰期气温较现在低2.0—2.5℃。这些变化对植被和动物的生存、迁移以及人类活动产生深刻的影响。此外,多年冻土下限和雪线高度与现代相比有明显的变化。

Using paleobotanic and paleofauna data as indirect evidence and periglacial data as direct evidence, we believe that the southern limit of permafrost was located at 39 - 40°N, the climate changed considerably both in the temperature and precipitation, which greatly influenced the migration and distribution of botany, fauna hunam beings during Holocene. The temperaure is 1 - 2 C higher during Hypsitherma and 2. 0 - 2. 5 C lower during little ice than today. In addation, the lower limit of permafrost and highth of mountain snow line changed obiviously to today.
