寒区冻土环境与人类活动联系越来越紧密,人类工程活动已逐渐成为影响冻土及其生态环境的重要因素,是导致冻融灾害的主要因素。本文定性地讨论了人类工程活动对冻土及环境变化的影响,并提出了对冻土工程活动进行分类的思想,并给出一种分类方法。
The relationship between the permafrost environment and human activities has become more and more close. The human engineering activities have gradually become the important factors affecting the permafrost and its ecological environment, and are the main factors leading to the freeze-thaw disaster. This paper qualitatively discusses the impact of human engineering activities on the permafrost and environmental changes, and puts forward the idea of classification of permafrost engineering activities, and gives a classification method.
