人类活动及各种工程措施的实施加速了高山多年冻土领域的相关研究,多年冻土的分布与制图成为该领域的研究热点之一.对该领域内的冻土勘察方法、冻土模型的建立、冻土分布模拟与制图等国内外研究现状进行了回顾和总结,高山多年冻土模型无论是经验统计模型,还是过程模型,都是基于对实地高山多年冻土分布状况的一种近似模拟,因而,或多或少的存在一定的误差,模型的好坏在于所绘制的高山多年冻土图与冻土实际分布状况的吻合程度.从各种高山冻土模型与制图的发展过程来看,高山多年冻土模型与制图的未来研究呈现出多元化研究和细化研究的趋势.
Alpine permafrost refers to the permafrost existing at high altitude in the middle and low latitudes,which involve so-called high-altitude and high mountain permafrost.In the recent years,various kinds of human and engineering activities implemented in mountain areas accelerate the development in the field of mapping and modeling the distribution pattern of alpine permafrost.The subjects about the distribution of alpine permafrost,the regional permafrost modeling and mapping etc.are all paid a large amount of attentions by experts in the world in the past decades.In this paper,the past and present development in the field about measuring methods in the field,permafrost survey and zonation,mapping and modeling in China and abroad is reviewed,and their virtues and shortcomings are also summarized.Finally,it is pointed out that the development tendency in the filed of modeling and mapping of alpine permafrost in China and abroad.
