青藏高原冻融侵蚀动力特征研究

Dynamic and Characteristic of Freezing Thawing Erosion on Qinghai Tibet Plateau

青藏高原的地理、地质和气候都具有特殊性 ,因而其土壤侵蚀是以冻融侵蚀为主结合其它多种侵蚀类型的侵蚀作用 ,具体分析了青藏高原冻融侵蚀的动力和 3种特殊形态的冻融侵蚀。为了减少水土流失 ,保护高原生态环境 。

Because of the special geography, geology and climate on Qinghai Tibet Plateau, the water and soil loss type is mainly of freezing thawing erosion blended with the other water and soil loss forms on Qinghai Tibet plateau. The dynamics of the freezing and thawing erosion on Qinghai Tibet Plateau were discussed, and three special types of freezing and thawing erosions are also discussed. A few of opinions are given for controlling water and soil loss and protecting ecological environment on Qinghai Tibet Plateau.
