摘要: 国际上很多学者如J·Tricart(1970)、(1959)、J.Demek(1978)等都一致认为冰缘地貌学的发展主要是在第二次世界大战以后,也就是近三十余年来的事[1、2]。我国冰缘地貌学的发展则完全是随着新中国的成长,壮大而逐渐发展起来的。在我国各个地貌学分支中它是最年轻的分支之一[3]

Abstract: Our progress in the studies of perigiacial landform is as follows :1, It has been established basically the types, distribution and characteristics of perigiacial landforms, some of which are rarely seen before and are specific to this region such as, rock-like ice cap or covering-type rock glacier, the thawing slide-mass, pingo and self-extrusive pingo and stratified scree and so on.2, Perigiacial landform has been divided bacically into three regional kinds : the continental type, subcontinental type and maritime type.3, We found that snow line is not the upper limit of perigiacial process. There are still several perigiacial processes above the snow line. Besides,we also found that there is a rockfield line-lower limit of rockfield onthe slope of high mountains. It is an important line of climatic geomor-phology.4, We have divided basically the types and features of the vertical zones of the perigiacial landform on high mountains.5, We have preliminary recognized the features of perigiacial deposit.
