In past century, much of the world's polar and mountain ice has melted, and in the past few decades the melting has accelerated. Ice is essential to global climatic and ecological stability, and as the ice turns to water. Enhanced melting is among the first observable signs of human-induced global warming, and glaciers and other ice features are particularly sensitive to temperature shifts. Loss of the ice would not only affect the global climate, but would also raise sea levels and spark regional flooding,...

In past century, much of the world's polar and mountain ice has melted, and in the past few decades the melting has accelerated. Ice is essential to global climatic and ecological stability, and as the ice turns to water. Enhanced melting is among the first observable signs of human-induced global warming, and glaciers and other ice features are particularly sensitive to temperature shifts. Loss of the ice would not only affect the global climate, but would also raise sea levels and spark regional flooding, damaging property and endangering lives. Large-scale ice melting would also threaten key water supplies as well as alter the habitats of many of the world's plant and animal species. As mountain glaciers shrink, large regions that rely on glacial runoff for water supply could experience severe shortages. Rapid glacial melting can also cause serious flood damage, particularly in heavily populated regions such as the Himalayas, Karakorum and Tienshan Mountains. As a whole, the world's glaciers are now shrinking faster than they are growing, and losses in 1997—1998 were “extreme”, up to -797mm weq. Scientists predict that up to a quarter of global mountain glacier mass could disappear by 2050. Within the next 35 years, the Himalayan glacial area alone is expected to shrink by to 100,000 square kilometers. In China, the glacier area of northwest China has reduced by 1338 km2 in recent 35 years, which constitute 4.9% of the total existing glacier area. A glacial lake in the Inilcheck Glacier of Tienshan Mountain, the Lake Mertzbakher, bursts once time every year in recent decades, and peak and total discharges of the Jokulhlaup flood from the lake have a general increasing trend as regional warming and glacier melting enhanced. Recent records of the Jokulhlaup events in the 1990s have indicated that the lake volume and peak discharge are becoming larger and larger corresponding to a warming and wetting of the inner Asian continent. The eastern Himalayas, which sit in the Ganges basin, have the severest melts. Due to unusual monsoon patterns, and possibly to global warming, those glaciers on the "roof of the world" from Bhutan to Kashmir are shrinking fastest. Environmental degradation is worsening many natural disasters; global environmental trends have reached a dangerous crossroads as the new century begins.

In term of natural geograghical districts , Northwest region not only includes Shaanxi, Ningxia, Gansu, Qinghai, Xingjiang ,but also includes western part of Inner Mongolia autonomous region and Shanxi, which can be divided 8 secordary natural districts. From historical period to today, many changes of ecological environment had happened in this region as follows:1. All the natural vegetation nearly disppeared; 2. Water and soil erosion became more serious; 3. Soil desertification became larger; 4. Snow line of glacier shrink a lot; 5. Rivers and lakes changed seriously; 6. Oasis became smaller and smaller. Generally speaking, its changing characteristics mainly included: Dry is main characteristics of ecological environmental change; The reason of ecological environmental change is weather as well as human-being behavior; The change of ecological environment is obvious during Qinhan,Tang and Mingqing period, it is more obvious after the building of people's republic of China; The change of ecological environment not only affected development of social and economic of this region,but also affected ecological safety of northren plain and Beijing-Tianjing region.

我国西北地区按自然地理区域划分 ,除包括今之陕西、甘肃、宁夏、青海、新疆等 5省、自治区外 ,还当划入内蒙古自治区西半部与山西省。其下又可分为 8个二级自然区。这一地区在历史时期以迄现代 ,生态环境发生了多方面的明显变化 ,主要是 :1 .天然植被大多消失殆尽 ;2 .水土流失不断加剧 ;3.土地沙漠化扩大 ;4.高山冰川雪线后退 ,冰雪储量减少 ;5.河流湖泊变化显著。一些河流河道流程减少、发生断流 ,有的湖泊湖面缩小、甚至消失 ;6.绿洲萎缩。总结其变化特征主要为 :生态环境变化主要反映在干旱化、沙漠化与水土流失不断加剧 ;生态环境发生变化的原因既有气候干旱化的影响 ,也与人为活动关系密切 ;生态环境变化在历史时期以秦汉、唐、明清时期最为显著 ,中华人民共和国建立后更趋剧烈 ;生态环境变化影响广泛深远 ,不仅制约着本地区社会经济的发展 ,还威胁着其周边地区 ,尤其是其东部华北平原与京津地区之生态安全。

An optimization of a 2-step thermal method was used to determine organic carbon (OC) and element carbon (EC) concentrations in snow and ice from the Tibetan plateau. OC is removed from the quartz filter under a pure oxygen atmosphere during the first combustion step at 340 ℃. The remaining carbon defined as EC is oxidized at the next combustion temperature of 650 ℃. Background contamination of 0.50±0.04 (1σ) μg C for OC, and 0.38±0.04 (1σ) μg C for EC are determined by blank tests. EC and OC concentrations in...

An optimization of a 2-step thermal method was used to determine organic carbon (OC) and element carbon (EC) concentrations in snow and ice from the Tibetan plateau. OC is removed from the quartz filter under a pure oxygen atmosphere during the first combustion step at 340 ℃. The remaining carbon defined as EC is oxidized at the next combustion temperature of 650 ℃. Background contamination of 0.50±0.04 (1σ) μg C for OC, and 0.38±0.04 (1σ) μg C for EC are determined by blank tests. EC and OC concentrations in snow samples collected from 8 glaciers in the Tibetan plateau were analyzed by this method. The results allow quantification for the first time of the different carbonaceous particle contents in the Tibetan plateau and other regions. The concentrations of EC and OC particles in snow in the Plateau show a clear decreasing trend, excluding the west Kunlun region, from east to west and from north to south. The highest mean EC content, 79.2 ng·g -1, was found in the northeast region, and the lowest, 4.3 ng·g -1, in the western Himalayas. We note that snow melting will result in accumulation of carbonaceous particles on glaciers, which suggests that such melting can reduce snow albedo and accelerate glacier shrinking.

文中采用供氧两步加热的方法对过滤到石英膜上的雪冰中碳质气溶胶含量进行分析,其中有机碳(OC)和元素碳(EC)分别在340和650℃的条件下进行热解、氧化分离,生成的CO2转化成CH4并由气相色谱仪氢火焰离子化检测器(FID)检测其含量。空白测试表明,该系统的OC本底值为(0·50±0·04)(1σ)μgC,EC为(0·38±0·04)(1σ)μgC。利用这套分析系统对青藏高原8条冰川的34个雪冰和降水样品中OC和EC的含量进行了测试。结果表明,在青藏高原雪冰中OC和EC含量自东向西、自北向南呈明显的下降趋势(西昆仑除外)。在高原东北部EC的质量分数相对较高,平均为79·2ng·g-1;在喜马拉雅西段EC的质量分数最低,平均为4·3ng·g-1。在冰川表面,雪的融化使雪冰中碳质气溶胶聚集,并导致其含量明显升高,该过程降低了雪表面的反照率,加速了冰川的消融。
