The Yulong Snow Mountain (YSM) is a region of temperate glaciers in the southeast Qinghai-Tibetan Plateau. The present study systematically assessed the glacier changes during the past several decades using ground-based and remotely sensed observations and referencing topographic maps. The images and maps revealed that the glaciers area in the YSM retreated by 64.02% from 1957 to 2017. The length of Baishui River Glacier No. 1 decreased by 12.5 m/year during this period, whereas the front elevation of this glacier increased by 10.83 m/year. The mean annual mass balance of this glacier was at − 0.42 metre water equivalent from 1957 to 2017, and its accumulative mass balance was − 27.45 metre water equivalent. The glacier retreats of glacier area, glacier front, and mass balance in the YSM primarily resulted from the increasing air temperature. These glacier retreats not only will have a negative impact on glacier tourism in the future, e.g., the retreat or disappearance of glaciers will reduce the attractiveness of mountainous scenic spots, but also will create new opportunities for the development of local tourism, e.g., “last chance” will simulate tourists’ curiosity. Hence, the findings of our present study help to understand the mechanism between accelerated ablation of temperate glaciers and climate change in southeast regions of Qinghai-Tibetan Plateau and provide references for local tourism administrations.

青藏高原东南部玉龙雪山冰川加速变化

玉龙雪山（YSM）是青藏高原东南部的一个温带冰川地区。本研究使用地面和遥感观测并参考地形图，系统地评估了过去几十年的冰川变化。图像和地图显示，从1957年到2017年，YSM的冰川面积减少了64.02％。在此期间，白水河1号冰川的长度减少了12.5 m / year，而该冰川的前高程增加了10.83。我的耳朵。从1957年到2017年，该冰川的年平均质量平衡为-0.42米水当量，其累积质量平衡为-27.45米水当量。YSM中冰川面积，冰川前缘和质量平衡的冰川退缩主要是由于气温升高所致。这些冰川撤退不仅会对未来的冰川旅游业产生负面影响，例如冰川的撤退或消失将降低山区风景名胜区的吸引力，而且还将为当地旅游业的发展创造新的机遇，例如“最后的机会”将模拟游客的好奇心。因此，本研究的结果有助于了解青藏高原东南部地区温带冰川加速消融与气候变化之间的机制，并为当地旅游行政管理提供参考。，“最后机会”将模拟游客的好奇心。因此，本研究的结果有助于了解青藏高原东南部地区温带冰川加速消融与气候变化之间的机制，并为当地旅游行政管理提供参考。，“最后机会”将模拟游客的好奇心。因此，本研究的结果有助于了解青藏高原东南部地区温带冰川加速消融与气候变化之间的机制，并为当地旅游行政管理提供参考。
