Urumqi Glacier No.1

Glacier No.1 has longer observation history and fuller records than any other glacier in China.^[3] In June 1958, Daxigou Weather Station was established right below Glacier No.1 at the mountainside of Tiangeer Peak, to measure and analyse the weather conditions in the area.^[8] In 1959–60, the research group for the use of mountainous ice and snow, Chinese Academy of Sciences, sent 8 sub-groups to investigate into the glaciers in Tian Shan, during which Tianshan Glaciological Station near Glacier No.1 was set up by Shi Yafeng in 1959. The glacier was first named as Shengli Daban Glacier No.1 before changing to the current name.^[9] In 1967–1979, the Cultural Revolution and other factors interrupted the observation.^[10] In 1982, the glacier became part of World Glacier Monitoring Service as a reference glacier. In 2010, an observation tower was built in the glacier area.^[11] In 2013, the glacier was listed among the sites for Global Cryosphere Watch.^[12]

Several modelling and predictions of Glacier No.1 have been put. Duan et al. (2012)^[13] estimated that by 2040, the terminus of a glacier will be retreating at a relatively slow rate but the thickness of the glacier will be significantly reduced, while after 2040, the retreat of the terminus will be speeding up. According to Gao et al. (2018),^[14] by 2040, the ice of the glacier will be 1/5 as large as it was in 1980, with the area halved. By 2100, 92% of the glacier area will be gone.

During Xinjiang's Lianghui session in 2012, Cui Chunyu, Regional People's Representative, proposed an initiative to set up a comprehensive natural protection area covering an area of 240 km² (93 mi²) surrounding Glacier No.1.^[15] In 2013, the Regional Environmental Protection Bureau set up a framework for the establishment of such protection area. In April 2014, the Regional Government decided to set up the protection area. In 2017, Project for protection of the ecology of Urumqi rivers and lakes started to be carried out, which included the protection area for Glacier No.1. The whole project cost 560 million RMB, involving 3 counties surrounding the area, covering an area of 950 km² (370 mi²).^[16] Plus, the government of Urumqi County has been applying for setting up a new national park.^[16]

To reduce human activity near the glacier, tourism surrounding the glacier was banned by the Regional government during the 13th 5-year Plan (2016–2020).^[7] Yet, this is challenged by doubt and concerns, for tourism is not the main cause of the glacier retreat but can help people to understand the importance of environmental protection and pollution reduction if well governed.^[17]

The grazing industry was relocated to reduce its influence to the glacier, and the herding routes were re-designed.^[6] The regulation over the manufacturers and miners was tautened. The number of cars passing through part of National Highway 216 near the glacier was restricted and the construction of a new road to replace the current route that is too close to the glacier is being planned.^[18][6]
