| Abstract: | In order to understand the distribution patterns of permafrost in the Wenquan area on the Qinghai-Tibet Plateau,the effects of altitude,slope and aspect and other topo-climatic factors on the distribution of permafrost were studied,using the correlation analysis with digital elevation(DEM) data,borehole observations and measures from ground penetrating radar(GPR) and the electromagnetic sounding method.A permafrost distribution model based on the nonlinear multiple adaptive regression splines(MARS) method w... |
