摘要
退化是本区多年冻土变化的基本趋势,不同区段退化幅度有差异,影响退化的因素除了全球气候转暖外,还有局地气候和地下水迳流。在退化敏感的地带,工程建设,牧区生态平衡都有不可忽视的影响。
Trending to the degeneration is basic characteristic of development of permafrost in this region nowadays,and its ranges have differences in different sections. The influence factors of degeneration are monsoon,snowmantle and groundwater,besides warming of atmosphere of the Earth as a whole. In sensitive region ,it has great influence on engineering and ecologic balance in pastoral area.
