摘要/Abstract

摘要： 山西宁武“万年冰洞”是目前所知全球冻土带以外的垂直洞穴中保存的冰体规模最大、最多、最好的地区，国内外所罕见。为了确定“万年冰洞”的形态、大小及其在三维空间的展布情况，进行了EH4电导率成像系统测量。根据物探反演结果反映，冰洞空间分布范围南北长约25 m，东西宽约20m，局部小范围向北东延伸，总体上呈柱状，最大延深达85 m左右。从总体上看，“万年冰洞”洞体具有口小肚大的特征。“万年冰洞”的形成和保存是当地气候、环境变迁的缩影、真实的记录和见证，为研究该区和华北地区气候、环境演化趋势提供了实际资料。

Abstract: The unique “ten thousand ice cave” in Ningwu,Shanxi Province has the largest scale of the ice body preserved in the vertical cave with the most quantity and beauty except the global frozen soil zonal at present. In order to determine the shape, size and 3D distribution of this “ten thousand ice cave”,EH4 electromagnetic image system is used to maseaure sysmatically. The results of geophysical prospecting showed this ice cave extends about 25 m and 20 m in NS and EW direction respectively, and extends in NE direction locally.This cave distributes in the polar shape with 85 m deep. In the general,this “ten thousand ice cave” has the features of a smaller entry and a bigger middle part. The formation and retention of the ten thousand ice cave is the epitome, the true record and the witness of the same area climatic and environmental variation,which provides valuable practice evidence to deeply study the climatic and environmental change in this area and North China.

Key words: Ningwu area of Shanxi, ten thousand ice cave, geophysical prospecting survey, morphological characteristics
