    内陆湖和高山的冰河是西藏的高原上的重要的水资源。理解他们的变化为在水供应并且为气候的信息的检索和分析的变化的精确评估和预言是关键的。从关于西藏的高原上的 35 个高山的湖的以前的研究的数据被用来在湖水水平和区域调查变化。以时间的变化, 35 个高山的湖的区域能被划分成五个组:升起,升起秋天,掉落上升,波动,并且掉落。以空间变化,在喜玛拉雅的山,咔拉在谮山脉山,和 Qaidam 盆的高山的湖的区域趋于减少;在 Naqu 区域和 Kunlun 山的湖的区域增加了;并且在 Hoh Xil 区域和 Qilian 山的湖的区域波动。在湖水水平和区域的变化在气候与地区性的变化被相关。为在西藏的高原上的这些湖的变化的原因被分析,包括从气象学的数据的降水和蒸发,从中国冰河库存的冰河 meltwater。几个关键问题例如监视水平衡的挑战,限制到冰川的区域察觉,在检测湖的无常水级的变化和西藏的高原上的湖变化类型的可变区域边界被讨论。这研究有很指示的意义到地区性的气候变化。

    A brief overview of the ongoing climatic and environmental changes in Northern Eurasia serves as an editorial introduction to this, the second, special Northern Eurasia Earth Science Partnership Initiative (NEESPI) focus issue of Environmental Research Letters. Climatic changes in Northern Eurasia over the last hundred years are reflected in numerous atmospheric and terrestrial variables. Many of these are noticeably significant above the confidence level for 'weather' or other (fire regime, ecosystem change) noise and thus should be further investigated in order to adapt to their impacts. In this focus issue, we introduce assorted studies of different aspects of contemporary change in Northern Eurasia. Most of these have been presented at one of the NEESPI workshops (for more information see neespi.org) and/or American Geophysical Union and European Geosciences Union NEESPI open sessions during the past year. These studies are diverse, representing the diversity of climates and ecosystems across Northern Eurasia. Some of these are focused on smaller spatial scales and/or address only specific aspects of the global change implications across the subcontinent. But the feeling (and observational evidence) that these changes have already been quite rapid and can have global implications inspires us to bring this suite of papers to the readers' attention.

    基于 1990, 2000 和 2011 Landsat TM/ETM+ 遥感数据,在中国 Tianshan 山的三个时期的冰河信息被使用比率阀值方法(TM3/TM5 ) 和视觉解释提取,与在 GIS 的卫星图象和分析的数字处理结合了。在包围区域的气候数据被使用线性回归, Mann-Kendall 突然的测试,和 Morlet 小浪分析分析。学习结果显示出那:在 23 年调查上,冰河区域显著地减少了。在最后 12 年(2000 ~ 2011 ) 里,撤退的率开始加速了。最戏剧的冰河收缩发生在中央区域,在东方区域最低。在中国 Tianshan 山的吝啬的夏天温度和温暖的降水有一个增加的趋势,与 0.22  的率
