通过对青藏公路沿线实测年平均地温多元回归统计 ,建立了年平均地温与海拔、纬度的关系模型 .利用多年冻土分布下界的统计方程和关系模型及基于格网的地理信息分析系统 ,对青藏公路沿线多年冻土下界分布和多年冻土地温带分布进行计算机模拟 .结果表明 ,所建立的模拟模型能够反映青藏公路沿线多年冻土的区域分布特征 ,模拟结果基本上反映多年冻土分布状况 .
Based on the multivariate regression analysis of annual mean ground temperature measured along the Qinghai-Tibet Highway, a model of the relationship between annual average ground temperature and altitude and latitude was established. Based on the statistical equation and the relational model of the lower bound of permafrost distribution and the geographic information analysis system based on grid, The results show that the simulation model can reflect the regional distribution of permafrost along the Qinghai-Tibet Highway, and the simulation results basically reflect the distribution of permafrost.
