摘要

在特里格拉夫冰川(斯洛文尼亚朱利安阿尔卑斯山脉)进行的各种大地测量和激光雷达测量不仅可以研究冰川的范围，还可以研究冰川的厚度和体积的变化。这些测量也使计算冰川的大地质量平衡成为可能。利用1952年、1975年和1992年的冰川面积测量，以及1999年至2016年的年度冰川面积测量，计算了厚度和体积的变化。平均厚度由1952年的39.2m下降到2012年的2.45m。最大厚度由1952年的48.3 m下降到2007年的5.2 m。计算了2016年该冰川覆盖的1公顷面积的平均比物质平衡。1952 - 2016年，年比质量平衡为- 0.45m w.e.a - 1。

Thickness and geodetic mass balance changes for the Triglav Glacier (southeastern Alps) from 1952 to 2016

Various geodetic and lidar measurements performed on the Triglav Glacier (Julian Alps, Slovenia) make it possible to study not only the extent of the glacier but also changes in its thickness and volume. These measurements also make it possible to calculate the geodetic mass balance of the glacier. Thickness and volume changes were calculated using glacier area measurements from 1952, 1975, and 1992, and annually between 1999 and 2016. The mean thickness decreased from 39.2m in 1952 to 2.45m in 2012. The maximum thickness decreased from 48.3 m in 1952 to 5.2 m in 2007. The mean specific mass balance was calculated for the area of 1 hectare that the glacier covered in 2016. From 1952 to 2016, the annual specific mass balance was −0.45m w.e.a−1.

期刊介绍： Acta geographica Slovenica publishes original research papers from all fields of geography and related disciplines, and provides a forum for discussing new aspects of theory, methods, issues, and research findings, especially in Central, Eastern and Southeastern Europe. The review accepts original research papers and review papers. Papers presenting new developments and innovative methods in geography are welcome. Submissions should address current research gaps and explore state-of-the-art issues. Research based on case studies should have the added value of transnational comparison and should be integrated into established or new theoretical and conceptual frameworks. The target readership is researchers, policymakers, students, and others who are studying or applying geography at various levels. Submissions are accepted in English or Slovenian.
