| Abstract: | Based on the data of precipitation from four weather stations(Wudaoliang,Fenghuoshan,Tuotuohe and Amdo) in the permafrost regions along the Qinghai-Tibet Railway during the last thirty years,together with data of air temperature and surface temperature at the same time,the climate change in permafrost regions was analyzes in this paper,and it is revealed that the precipitation,air temperature and surface temperature have been in a increasing trend with undulation during last thirty years.The analysis result... |
