| 1 | 天山中部典型流域冰川变化及对气候的响应显示文摘利用2000年的Landsat5遥感数据、1970年和2009年的冰川编目数据,对天山中段南坡开都河流域和北坡玛纳斯河流域的冰川变化进行了对比分析,并结合地面气象站点数据分析了冰川对气候变化的响应及南北坡冰川变化的差异性.研究表明:1970-2009年间,两流域冰川面积减少了494.33km2,占总面积的26.8%(0.8%·a-1);冰川储量减少了32.73 km3,占总储量的27.9%(0.8%·a-1).其中,2000-2009年冰川面积和冰储量年退缩率(1.3%·a-1)比1970-2000年(0.6%·a-1)大;冰储量减少的速率略大于面积缩小的速率,说明冰川面积缩小的同时,其厚度在迅速减薄.1970-2000年和2000-2009年间,玛纳斯河流域的冰川年均面积退缩率分别为0.5%·a-1和1.4%·a-1,开都河流域的冰川年均面积退缩率为0.9%·a-1和1.1%·a-1,显示出玛纳斯河流域冰川在2000年后呈加速萎缩趋势.影响研究区冰川变化的主因是气温,而夏季升温幅度及降水的不同是造成南北坡冰川差异性变化的重要原因. | 朱弯弯 上官冬辉 郭万钦 许君利 | 2014 | 冰川冻土2014,36,6: | 18 |
| 2 | 高亚洲定位监测冰川平衡线高度时空分布特征研究显示文摘利用高亚洲定位监测冰川平衡线高度数据,对平衡线高度时空分布特征进行了分析.结果表明:高亚洲冰川平衡线高度在空间尺度上具有纬度地带性、经向地带性和区域性的特征.在时间尺度上,高亚洲定位监测冰川平衡线高度呈现不同程度的升高趋势.在天山山区,乌鲁木齐河源1号冰川和Ts.Tuyuksuyskiy冰川的平衡线高度在1960-2013年间,分别增加约116 m、80 m,二者相比,Ts.Tuyuksuyskiy冰川对气候变化的敏感性更高;在阿尔泰山区,No.125(Vodopadniy)冰川、Maliy Aktru冰川和Leviy Aktru冰川在1983-2007年间,平衡线高度变化趋势基本一致,总体都呈升高趋势,其中,Maliy Aktru冰川平衡线高度增幅最大,升高了约142 m;高亚洲定位监测冰川中,1962-2008年间,七一冰川平衡线高度升高速度最快,增幅最大,升高了约264 m,升高速度最为缓慢的是乌鲁木齐河源1号冰川,其增幅最小,升高了约47 m. | 叶万花 王飞腾 李忠勤 张慧 徐春海 怀保娟 | 2016 | 冰川冻土2016,38,6: | 9 |
| 3 | 冰冻圈过程对中国干旱区水文环境的影响评估显示文摘冰冻圈过程对中国干旱区的水文环境和社会经济的可持续发展有着特殊的作用和意义。本文阐述了通过系统分析、比较20世纪60年代以来中国干旱区积雪、冰川和冻土的站点观测资料及遥感数据而得出的中国干旱区冰冻圈的变化。主要结果表明:自20世纪70年代到2008年,中国干旱区80.8%的冰川有退缩。由于中国干旱区的冰川中85%以上的面积都小于1.0 km2,属小型冰川,这个退缩态势的持续可在未来十年至几十年减少冰川条数。与冰川变化相反,中国干旱区积雪面积稳定,超过8.8×105km2。积雪的初始和终止日期无明显变化。冻土方面,由于平均地温变暖,高山冻土下限深度从1992年到2008年减少了7.7 m,发生着自下而上的迅速退化。综合这些结果,文中提出了几点应对这些变化对水文环境影响的建议。 | 胡汝骥 陈曦 葛拥晓 刘时银 赵林 姜逢清 王亚俊 | 2015 | 干旱区研究2015,32,1: | 7 |
| 4 | Spatial variability of glacial changes and their effects on water resources in the Chinese Tianshan Mountains during the last five decades显示文摘Changes in glaciers in the Chinese Tianshan Mountains have been analyzed previously. However, most previous studies focused on individual glaciers and/or decentralized glacial basins. Moreover, a majority of these studies were published only in Chinese, which limited their usefulness at the international level. With this in mind, the authors reviewed the previous studies to create an overview of glacial changes in the Chinese Tianshan Mountains over the last five decades and discussed the effects of glacial changes on water resources. In response to climate change, glaciers in the Tianshan Mountains are shrinking rapidly and are ca. 20% smaller on average in the past five decades. Overall, the area reduction of glacial basins in the central part of the Chinese Tianshan Mountains is larger than that in the eastern and western parts. The spatial differentiation in glacial changes are caused by both differences in regional climate and in glacial factors. The effects of glacial changes on water resources vary in different river basins due to the differences in glacier distribution, characteristics of glacial change and proportion of the glacier meltwater in river runoff. | WANG Puyu LI Zhongqin HUAI Baojuan WANG Wenbin LI Huilin WANG Lin | 2015 | Journal of Arid Land2015,7,6: | 5 |
| 5 | 基于ALOSPALSAR的喜马拉雅山冰川流速分布及变化显示文摘基于2007年12月至2010年2月的12景ALOS PALSAR数据,结合SRTM,应用特征跟踪方法对喜马拉雅山冰川3个时段的流速进行了估算。结果表明,2007年冬季、2009年夏季和2009年冬季冰川流速均在0~300m·a-1之间,冰川积累区仅在夏季有较明显的运动,而冰舌部分的运动在任何季节都较为明显,并且长冰舌冰川流速沿主流线向下缓慢减小,而短冰舌冰川沿主流线向下流速不断波动变化,甚至增加。4个坡向中,东坡冰川流速最大,东南坡和西南坡次之,北坡冰川流速最小,除了与气候因素相关外,还与地形因素密切相关,从4个坡向的坡度大小来看,北坡坡度最小,也是造成北坡冰川流速最小的主要原因之一。冰川存在年际变化,即冰川冬季平均流速有所增加,增加的冰川流速在-5~18m·(2a)-1之间,并且面积大的冰川流速变化较小,面积小的冰川流速变化较大。同时冰川流速也存在季节性变化,夏季流速整体比冬季流速要大,冰川主流线上流速在夏季时波动较强烈,并且会出现多个峰值,而冬季主流线流速则较为平缓,但主流线上平均流速季节性差异并不明显。4条典型冰川流速年际变化、季节变化与研究区冰川总体特征相似,并且流速与气候特征和冰川形状之间都有密切的关系。冰川前进与退缩特征不明显,研究区冰川总体上处于平衡状态。 | 王仕哲 柯长青 | 2018 | 遥感技术与应用2018,33,5: | 5 |
| 6 | Comparative study on observed mass balance between East and West Branch of Urumqi Glacier No. 1, Eastern Tianshan, China显示文摘This paper is based on observed mass balance between East and West Branch of Urumqi Glacier No. 1, meteorological data during 1988-2010, comparative studies the mass balance variations, and analyses the mass balance sensitivity to climate change. Results show that average mass balance of East and West Branch was 532 mm/a and 435 mm/a, cumulative mass balance was 12,227 mm (ice thinned by 13.6 m) and 10,001 mm (ice thinned by 11.1 m), respectively, and mass loss of East Branch was 97 mm/a larger than West Branch. The East and West Branch ELA (equilibrium line altitude) ascended about 176 m and 154 m, analysis shows the steady-state ELA0 was 3,942 m a.s.l. and 4,011 m a.s.l., and when East and West Branch mass balance decreased by 100 mm, ELA ascended 20 m and 23 m, respectively. The AAR (accumulation area ratio) of East and West Branch presented an obviously decreasing trend of 34.5% and 23%, equilibrium-state AAR0 was 65% and 66%, when East and West Branch mass balance increased by 100 mm, AAR ascended 4.6% and 4.2%, respectively. Glacier mass balance was sensitive to change of net ablation, net ablation of East and West Branch increased 10×104 m3 , and mass balance decreased 110 mm and 214 mm, respectively. By analyzing mass balance sensitivity to climate change, results suggest that East and West Branch mass balance decreased (increased) 463 mm and 388 mm when ablation period temperature increased (decreased) by 1°C, East and West Branch mass balance increased (decreased) 140 mm and 158 mm when annual precipitation increased (decreased) by 100 mm, and sensitivity of East Branch mass balance to climate change was more intense than that of West Branch. | GuoFei Zhang ZhongQin Li WeiDong Wang WenBin Wang | 2013 | Research in Cold and Arid Regions2013,5,3: | 1 |
| 7 | 基于多源遥感数据的乌鲁木齐河源1号冰川平衡线高度研究显示文摘以我国天山乌鲁木齐河源1号冰川(以下简称1号冰川)为例,基于Landsat TM/ETM/OLI和Sentinel-2A MSI数据,利用归一化差异积雪指数(NDSI)和阈值法提取该冰川2002-2015年的平衡线高度,并利用站点实测的冰川ELA数据和气象数据对提取的平衡线高度进行了验证。结果表明,2002-2015年遥感获取的平衡线高度呈总体上升的趋势,与实测的平衡线具有高度相关性(r=0.9);ELA与年物质平衡序列高度相关,物质平衡波动的平均解释率可高达69%;与气象要素(温度和降水)年际变化的相关性也很高,约有59%的冰川ELA变化可以用夏季气温和降水来解释。因此,利用遥感数据可以提取高精度的冰川平衡线高度数据,对无站点数据冰川的平衡线高度以及物质平衡研究具有一定的借鉴意义。 | 崔督督 张彦丽 李忠勤 陈蔺鸿 | 2020 | 安徽农业科学2020,48,3: | 0 |
