摘要: 近几年来随着我国东北大、小兴安岭多年冻土南界的考察(1974,1979,1980)和青藏铁路的勘测,以及青藏综合科学考察的展开(1974—1978),冰缘地貌的研究又重新活跃了起来。同时,东北广大地区、内蒙、山西、冀北,也广泛发现古冰楔、冰卷泥等古冰缘现象。并开始试图划分冰缘期和进行对比。作者感到在如何确定古冰缘现象的时代及其与冰期进行对比等问题上有必要进行及时的讨论,敬请读者指正。

Abstract: The author considers that based on the geomorphologic site, stratigraphical correlation, material source, weathering degree and chronological data, division of the period of periglacial phenomenon could be made.But the distinction between syngenetic and epigenetic phenomena should be effected at the same time.The author further suggests that the term" paraperiglaciai age"be used to indicate the periglacial age in high mountains and on plateau at lower-middle latitudes, especially on Qinghai- Xizang plateau of extreme magnificent size or in unglaciated area of high latitudes during the interglacial period, for a lot of periglacial phenomena develop well at the same time. So the term"interperiglacial age"seems to be impertinent.
