摘　　要：以青藏高原的腹地区域-可可西里自然保护区土壤发生过程为例,探讨了地学因素对高海拔地形区地域成土作用的影响及高海拔地形区地域土壤形成与发育的特殊性,提出了高原地形区的地势、母质、水文地质等地学因素对土壤形成和发育的影响与作用远远超过其他因素,表现为极具特色的土壤形成发育过程特征:地貌类型简单造成土壤类型单一化;成土母质深刻地影响着土壤的形成和发育;土壤发育受第四纪冰川影响明显,成土年龄短;新构造运动是控制土壤分布的重要因素.In this paper the effect of terrain factors on soil forming process in high altitude region was studied by taking KEKEXILI Natural Reserve hinterland in Qinghai-Tibet Plateau as an example,and the particularity of this process was also studied. The results show that influence and function of topography, mother soil quality, hydrogeology and other terrain factors on forming and development of the soil far exceed other factors in Plateau, showing the particular characters of soil forming process in these regions. The simple physiognomy type causes the soil type to simplify; The mother soil quality is influencing forming and development of the soil deeply;The glacier influence of Quaternary Period affect soil development obviously;The age of soil forming is short; The new tectonic movement controls the important factor that the soil is distributed.
