| 摘 要： | 气候是多年冻土形成与变化的动力,局地因素则通过改变地表辐射、对流和传导过程对多年冻土产生影响,导致多年冻土发生空间分异.应用青藏公路沿线大量的观测资料分析了局地因素对多年冻土区地温所产生的影响.结果表明:地形地貌、植被、积雪、土壤性质及含水量等局地因素,对青藏公路沿线地区多年冻土的发育和多年冻土热状况有显著影响.局地因...

| Abstract: | As a result of water and energy exchange between atmosphere and soils through ground surface,permafrost takes place under a certain climatic conditions and local factors.Among them,climate is the driving force of permafrost formation and evolution,while local factors lead to regional differentia of permafrost distribution and thermal regime.The permafrost temperatures observed mainly along the Qinghai-Tibet Highway are used to analyze the influence of local factors on permafrost thermal regime,such as topog... |
