| 1 | 近50a气候变化背景下青藏高原冰川和湖泊变化显示文摘论文综述了近年来青藏高原冰川和湖泊变化研究取得的成果,并特别着重于冰川和湖泊变化的相互关系论述。在全球变暖背景下,近几十年青藏高原冰川以退缩为主,湖泊水量以增加为主。论文一方面对青藏高原冰川末端退缩、冰川面积和冰川储量变化方面的研究成果进行了综合分析,探讨了冰川变化的时空特征;另一方面从湖泊面积和水位与水量变化探讨了湖泊变化的时空规律。结果表明青藏高原冰川退缩的幅度总体上呈从青藏高原外缘向内陆呈减小的变化态势,受冰川融水补给比较大的湖泊近期面积扩张、水位上升明显。最后指出了青藏高原冰川、湖泊变化研究中存在的问题及今后的发展趋势。 | 李治国 | 2012 | 自然资源学报2012，27，8： | 41 |
| 2 | Recent glacial retreat and its effect on water resources in eastern Xinjiang显示文摘The eastern Xinjiang Basin is desperately short of water. Most rivers in the basin originate in the high eastern Tianshan, which has abundant precipitation and numerous alpine glaciers. Fieldwork conducted on three reference glaciers around Mt. Bogda in 1981 and 2009 suggests that they all strongly melt in summer, a process that has tended to accelerate in recent decades. Based on topographic maps from 1962 and 1972 and 2005/2006 satellite imagery, we investigated 203 glaciers near Mt. Bogda and 75 glaciers near Mt. Harlik. The results show that the surface area of the Mt. Bogda glaciers decreased by 21.6% (0.49% a?1) from 1962 to 2006. This was accompanied by a 181 m decrease in length and a 28% drop in ice volume. In the Mt. Harlik region, areal extent was reduced by 10.5% (0.32% a?1), length by 166 m, and volume by 14% between 1972 and 2005. South-facing glaciers lost more of their area than those that are north facing, yielding an areal loss of 25.3% and 16.9% for southern and northern slopes of Mt. Bogda, respectively, and 12.3% and 6.6% for the comparable slopes of Mt. Harlik. Glaciers smaller than 0.5 km2 in area experienced the strongest retreat, whereas glaciers larger than 2 km2 in area experienced gentle recession but may be the main contributors in the future to river runoff. Glacial ablation in eastern Xinjiang tends to be strong, and the water resources in this region are deteriorating. Also, a heavy reduction in the capacity of the local karez system, as well as a significant change in river runoff, can be related to glacial retreat. Combined, this will adversely affect the downstream city of Urumqi and the Turfan Basin. | LI KaiMing LI ZhongQin GAO WenYu WANG Lin | 2011 | Chinese Science Bulletin2011，56，33： | 23 |
| 3 | Vulnerability assessment of areas affected by Chinese cryospheric changes in future climate change scenarios显示文摘Using the definition of vulnerability provided by the Intergovernmental Panel on Climate Change,this paper assesses the vulnerability of areas affected by Chinese cryospheric changes from 2001 to 2020 and from 2001 to 2050 in A1 and B1scenarios.Seven indices are used in the vulnerability assessment:glacial area fraction,interannual variability of permafrost depth,interannual variability of surface snow area fraction,interannual variability of surface runoff,interannual variability of surface temperature,interannual variability of vegetation growth,and interannual variability of the human development index.Assessment results show that the overall vulnerability of the studied areas in China increases from east to west.The areas in the middle and eastern parts of China are less vulnerable compared with western parts and parts of the Tibetan Plateau.The highest vulnerability values are found from 1981 to 2000,and the least ones are found from 2001 to 2050.The vulnerable areas increase from the period of 1981 to 2000 to the period of 2001 to 2050,and the less vulnerable areas decrease.The highly vulnerable areas increase from the period of 1981 to 2000 to the period of 2001 to 2020 and then decrease from the period of 2001 to 2020 to the period of 2001 to 2050.This decrease in vulnerability is attributed to the decrease in exposure and sensitivity to Chinese cryospheric changes along with a concomitant increase in adaptation. | HE Yong WU YongFeng LIU QiuFeng | 2012 | Chinese Science Bulletin2012，57，36： | 18 |
| 4 | Thinning and Shrinkage of Laohugou No. 12 Glacier in the Western Qilian Mountains, China, from 1957 to 2007显示文摘Landsat images, real-time kinematic GPS measurements, and topographic maps were used to determine changes in ice elevation, volume, and areal extent of the Laohugou No. 12 glacier (Qilian Mountains, China) between 1957 and 2007. The glacier experienced significant thinning and areal shrinkage in the ablation zone, but slight thickening in part of the accumulation zone. Elevation decreased by 18.6±5.4 m between 1957 and 2007 in the regions covered by the GPS measurements. The total volume loss for the entire glacier was estimated to be 0.218 km3 using a third-order polynomial fit method. The area diminished by 0.28 km2 between 1957 and 1994, 0.26 km2 between 1994 and 2000, and 0.28 km2 between 2000 and 2007, suggesting that the rate of loss in glacial coverage has increased since the mid-1990s. Significant increases in annual mean air temperature may have contributed to shrinkage and thinning of the glacier. | ZHANG Yingsong LIU Shiyin SHANGGUAN Donghui LI Jing ZHAO Jingdong | 2012 | Journal of Mountain Science2012，9，3： | 16 |
| 5 | Numerical simulation of Urumqi Glacier No.1 in the eastern Tianshan,central Asia from 2005 to 2070显示文摘Due to climate changes, most of the alpine glaciers have retreated dramatically during the past decades. Thus it is significant to predict the alpine glacier variability in the future for a better understanding of the impact of climate changes on water resource. In this paper, we perform the numerical simulation on Urumqi Glacier No.1 in the eastern Tianshan, central Asia (hereafter Glacier No.1 for short) by considering both the mass balance and ice flow. Given the shape of the Glacier No.1, the velocity of the glacier is obtained by solving a two-dimensional nonlinear Stokes equation and simulated result is in agreement with the observation. In order to predict the variability of Glacier No.1 in the next decades, a climatic scenario is constructed with a temperature rise rate as 0.17°C/10 a and precipitation as constant during the period of 2005-2070. The simulation shows that, the glacier terminus will retreat slowly and the glacier will thin dramatically before 2040, while after year 2040, the glacier terminus retreat will accelerate. This study confirms the increasing retreat rate of alpine glaciers under global warming. | DUAN KeQin YAO TanDong WANG NingLian LIU HuanCai | 2012 | Chinese Science Bulletin2012，57，34： | 7 |

| 8 | 地面多基线数字摄影测量在冰川测量中的应用——以博格达峰黑沟8号冰川为例显示文摘冰川的监测一直是冰川学研究的重要内容,2008年对天山东段博格达峰南坡的黑沟8号冰川末端进行了地面多基线数字摄影测量,获取了该冰川末端的影像,以及与之相配套的控制信息.在Lensphoto多基线数字摄影测量系统中,测得了冰川末端的0.11km2 DEM数据.采用同期测量的GPS数据检验得知,摄影测量所得DEM数据在高程上的平均误差为1.92m,标准偏差为3.47m.地面旋转多基线数字摄影测量是一种非常有效的冰川测量手段,可以在典型冰川测量和冰川重要部位(例如冰川末端、冰崖等)的测量中发挥作用. | 张盈松 刘时银 上官冬辉 | 2012 | 冰川冻土2012，34，5： | 3 |
| 9 | High Asia cryospheric observation:a proposed network under Global Cryosphere Watch(GCW)显示文摘In coordination with Global Cryosphere Watch(GCW) initiated by World Meteorology Administration(WMO),a regional observation network is proposed based on existing stations/sites over High Asia and cryospheric elements required by GCW.Thus,High Asian Cryosphere(HAC) network is preliminary designed,composing of seven 'supersites',each containing several reference sites.The network covers major mountain ranges in High Asia,such as East Tianshan,Qilian,Tanggula,Nyainqentanglha,Himalayas as well as the central and eastern Qinghai-Xizang(Tibet) Plateau.Although multiple cryospheric elements were observed at the existing HAC network,many others,which are required by Integrated Global Observation System-Cryosphere Theme(IGOS-Cryosphere),are not yet included.More comprehensive observations are necessary to be included into 'supersites' of HAC,so that the basic requirements for validation of satellite data,assimilation and coupled regional models can be met. | CunDe Xiao ZhongQin Li Lin Zhao ShiChang Kang YuanQing He Xiang Qin XiaoBo He | 2012 | Research in Cold and Arid Regions2012，4，1： | 0 |
