摘要
根据２１４国道沿线花石峡地区的气候变化特征和自然地理及地质水文条件，以该区长石头山连续多年冻土区４０ｍ深实测地温为基础，并以年平均气温升速率０．４℃／１０ａ为前提，对该区气候变化与多年冻土退化的关系等进行了模拟预测．
The relationship between climate changes and permafrost degradation is modeled and predicted, in relation to the continuous permafrost district of Changshitou Mountain in Huashixia Valley according to the natural geographic and geologic conditions. At the same time, the degrading trend of the continuous permafrost of Changshitou mountain is also predicted according to the warming condition of the atmospheric temperature, which will rise 0.4 ℃ every ten years.
