在全球变暖影响下，北半球高纬度冻土区经由比全球其他区域更快的增暖速度而逐年退化，反馈于全球气候及生态等诸多领域。基于冻土范围影响因子研究方向的研究现状及发展前景，我们对北半球高纬度积雪范围与冻土范围相关影响机制进行研究，通过编程处理1980年至今30°N以北范围的气象数据并分析二者相关性与作用机制，并对CESM2等多个气象模型数据进行处理并比对分析其差异，从而为数据处理与分析结果增加信度。本文得到较为可靠的数据处理与分析结果，期望对研究积雪对于冻土区作用效应提供一定的参考，并关注冻土区对于我国气候、环境及生产发展与调制等方面的重要影响。

Under the influence of global warming, the high latitude permafrost regions of the Northern Hemisphere are deteriorating year by year through faster warming rates than other regions of the world, feedback on many fields such as global climate and ecology. Based on the current research status and development prospects of the research direction of impact factors on frozen soil ranges, we conducted research on the relevant impact mechanisms of the high latitude snow cover range and frozen soil ranges in the Northern Hemisphere. Through programming, we processed meteorological data from 1980 to the north of 30 ° N and analyzed their correlation and function mechanisms. We also processed different meteorological model data such as CESM2 and compared and analyzed their differences, thereby increasing reliability for data processing and analysis results. The reliable data processing and analysis results obtained in this paper are expected to provide some reference for studying the effects of snow cover on permafrost regions, and pay attention to the important impacts of permafrost regions on China's climate, environment, and production development and modulation.
