What’s the water level trend of Qinghai Lake in the past? What were the reasons for that?

过去青海湖的水位走势是什么样的，原因是什么？

• I see the information at Baidu Net: the water of Qinghai Lake dried, the lake has been dry all. The water level often decline, the land was drought.(我在百度网看见资料：青海湖以前比较干，湖水都晒干了。水位经常下​降，土地干旱。)
  Apr. 15, 2009

   
  
  

• I knew from the information I found:In the past forty years, the water level of Qinghai Lake was on the decline. Wetlands and marsh area are on the decline, too.(我从查到的资料中看到，进四十年来，青海湖的水位在下降。湿地面积和沼泽面​积都在减少。)
  Apr. 08, 2009

   
  
  

• The water level of Qinghai Lake continues decline, it will cause serious mineralization. If it enters a vicious cycle of ecological environment, Qinghai Lake will die after a hundred years. In other words, we can't enjoy the beautiful scenery of the Qinghai Lake. This is a sad thing! Data shows that the Qinghai Lake on east-west direction at approximately 20 kilometers back. Qinghai Lake is compared to the Qinghai Lake ten thousand years ago, with an area reduction of one third , the water level dropped by more than 100 meters.
  Apr. 08, 2009

   
  
  

• In the past, the water level trend of Qinghai Lake was dropping. First, because of drought, the runoff of feeding rivers around Qinghai Lake and the water surface precipitation of Qinghai Lake was small. Second reason was global warming and large evaporation of lake surface. Once people had asserted that, Qinghai Lake would disappear after 200 years.
  
  (过去青海湖的水位一直处于下降趋势。一方面由于干旱，使环青海湖地区的补给河流径流​量和青海湖水面降水量小；另一方面气候变暖，湖面蒸发量大，使青海湖的水位呈下降趋势
  Apr. 08, 2009

   
  
  

• Qinghai relatively drought, very little rain, Qinghai lake water evaporation, and therefore, in the past the water level of Qinghai Lake has been declining, and the surrounding areas of Qinghai Lake is also less and less grassland desertification is also a situation more and more serious.
  
  青海比较干旱，很少下雨，青海湖里的水蒸发的多，所以，过去青海湖的水位一直是下降的​，而且青海湖周边地区的草地也越来越少，土地沙化现象也是越来越严重的。

Protective measures(保护措施)

What protective measures did the provincial government adopt?

省政府采取了哪些保护措施

• Qinghai Province implementated the project of returning farmland to forest to arable land around Qinghai Lake. Water management department carried out a project for ecological restoration of soil and water conservation in a large area.At Qinghai Lake through artificial enhancement measures, released and incubated naked carps.青海省对青海湖周围的耕地逐步实施退耕还林工程。水利部门加大了管理力度​，开展了大面积的禁牧育草等水土保持生态修复试点项目。在青海湖通过人工增值的措施，​放流孵化青海湖裸鲤。
  Apr. 08, 2009

   
  
  

• As far as I know, the provincial government of Qinghai Lake on the implementation of the arable land around the project of returning farmland to forest. Identified a decade of closure sterile fish lake view, the measures adopted by the proliferation of artificial hatching of fish Huangshui Qinghai Lake. Water Resources Department launched a sterile grass, artificial aids, such as ecological restoration of soil and water conservation.
  Apr. 08, 2009

   
  
  

• To protect Qinghai Lake, On May 26, 2008, Song Xiuyan, governor of Qinghai province declared that the project for protection and comprehensive control of ecological environment in Qinghai Lake valley was officially launched. The project investment was nearly 1.6 billion; of which the planning and implementation period is 10 years, and would be carried out in 4 countries that covering the whole Qinghai Lake valley: Gangca, Haiyan, Tianjun, Gonghe. With the implementation of the project, the ecological environment in Qinghai Lake valley would be efficiently protected and recovered; the dropping water level trend of Qinghai Lake would gradually be relieved; and would have great significance in maintaining ecological security of Qinghai-Tibet Plateau.
  
  
  ( 为了保护青海湖，青海省省长宋秀岩于2008年5月26日宣布，正式启动青海湖流域生​态环境保护与综合治理项目，投资近16亿元，规划实施期为10年期，将在青海湖流域的​刚察、海晏、天峻、共和4个县进行，覆盖整个青海湖流域。项目的实施，将有效保护和恢​复青海湖流域生态环境，逐步缓解青海湖水位下降的趋势，对维护青藏高原生态安全意义重​大。
  
  Apr. 08, 2009

   
  
  

• I knew that from books in the library : in Qinghai Province, through the protection of natural grassland and management of engineering, management of degraded grassland. The adoption of anti-desertification projects, soil and water conservation and water conservation works to solve the problem of desertification in Lake region(我从图书馆的书籍中查阅到:青海省将通过天然草地保护与治理工程,治理​退化的草地.通过防沙治沙工程,水土保持及水源涵养工程解决湖区沙化问题）.
  Apr. 08, 2009

   
  
  

• Qinghai provincial government has adopted a major returning farmland to forest, grassland, natural forest protection project, anti-desertification projects, closing hillsides to facilitate afforestation project, so that the ecological environment in Qinghai Lake Well more and more.
  (我省省政府主要采取了退耕还林、退耕还草、天然林保护工程、防沙治沙工程、封山育林​工程等，使青海湖的生态环境越来越好了。)

The reason of water level rise(水位上涨的原因)

What’re the reasons for the rise of water level of Qinghai Lake??

青海湖水位上涨的原因是什么？

• I know that through the information searching: the provincial government has increased the intensity of artificial rainfall, climate warming, the tip of the melt, the effective implementation of ecological measures to slow the decline the water level.Increase in precipitation in Qinghai Lake.通过查找资料我知道：省政府加大了人工降雨的力度，气候变暖，冰山融化，生​态措施实施有效，减缓了水位的下降。青海湖流域内降水还会有所增加。
  Apr. 08, 2009

   
  
  

• As we all know global warming, alpine glaciers, alpine snow continued to melt, water flows into the lake, so that water increased availability, the water level rose. According to the meteorological data: precipitation in our province last year increased than in the same period last year. It is one of the reasons why the water level digital up.（众所周知地球变暖,高山冰川,高山积雪持续融化,水流入湖里,使水量增加,水​位上涨.根据气象资料显示:去年我省降水量比去年同期增多。这也是青海湖水位上涨的原​因之一。）
  Apr. 08, 2009

   
  
  

• The main reasons for the rise are: 1) the degree of artificial precipitation is constantly enhanced. The continuously increasing of precipitation makes the additions in both runoff of rives in Qinghai Lake valley and water level of Qinghai Lake. 2) With the global warming, the melting glacier and snow around feeds Qinghai Lake, this causes water level rise. 3) During the past few years, cloudy and rainy weather arose more and more frequently in the area and lake surface evaporation decreased, which is also one important reason for the rise.
  
  (青海湖水位上涨的原因主要是：1）我们省不断加大青海湖地区人工降雨力度，降水量的​持续增加使环青海湖地区的河流径流量和青海湖水面降水量得以增加； 2）随着全球气候变暖，青海湖周边的冰川、积雪不断融化，融化的水不断流入到青海湖，​使青海湖的水位上不断上升；3）这几年青海湖上空出现多云和阴雨的天气较多，湖面水的​蒸发量就少了，这也是青海湖水位上涨的一个重要原因。)
  
  Apr. 08, 2009

   
  
  

• I see from the Internet: In the past, because of soil erosion, grassland decline in productivity, increasing desertification, leading to the declining of water levels.(我网上看到,过去由于水土流失,草地生产率下降，土地沙漠化，导致水​位下降．)
  Apr. 08, 2009

   
  
  

• The good and the bad could coexist about the Qinghai Lake-bit up,on the one hand,the water level increase could ameliorate on the local climate and provide healthy environment for fish longevity Huangshui.On the other hand,it coud lead to the melting of glaciers and the drying up of rivers,which can't supply enough water for the surrounding flowers and trees,it has no benefit to the future eco-development of Qinghai Lake.

Debate

Is it good or bad for the rise of water level
青海湖水位上涨是好事还是坏事？

Positions:

good (1)
bad (0)
both (5)

• both

  I think the rising of water level has both advantages and disadvantages.It's good for the surrounding plants to restore. Its disadvantage is the desertification of land as a result of grassland degenration which results from the drying up of rivers as the glaciers melt.He will affect the ecological environment of the Qinghai Plateau我认为青海湖水位上涨有利有弊。好处在于对周围植物的恢复有利；坏处在​于由于冰川消融殆尽，江河断流又导致草场退化，草场退化导致土地沙化，他会影响到青海​高原的生态环境。
  Apr. 08, 2009

   
  
  
• both

  It is clear that the rising water level of Qinghai Lake is a good and bad thing; To our delight, the surrounding environment is improving, meanwhile we feel deep concern about the future of the Qinghai Lake
  Apr. 08, 2009

   
  
  
• both

  I think it’s good, but negative factors still exist. On the one hand, the rising water level is propitious to the improvements of ecological environment of Qinghai Lake, and is propitious to the growth of naked carp (Gymnocypris przewalskii) and to the growth of vegetation in surrounding area. On the other hand, seeing from another angle, the rising water level of Qinghai Lake might be bad, that is, one of the main reasons for the rise is the global warming lead to the melting acceleration of glacier and snow on the nearby mountains. If this continues, the phenomenon that the rising water level of Qinghai Lake will be bad, that is to say, when all glacier and snow melt, rivers will be all dry up. The ecological environment of the whole valley will be worse which might finally affect the living environment of human being.
  
  我觉得青海湖水位上涨是好事，但也存在着不利的因素。因为，青海湖水位上涨有利于青海​湖周边生态环境的改善，有利于青海湖中湟鱼的生长和青海湖周边地区植被的成长。但是，​青海湖的水位上涨从另一角度看可能就是一件坏事。因为，青海湖水位上涨有一个主要原因​，就是气候变暖导致天然高山冰川和积雪融化速度加快所致，如果这样持续下去，青海湖水​位上涨的现象就会变成坏事，当冰川和积雪融化完以后，江河有可能就没有了流水，整个流​域的生态环境就会恶化，最终将会影响到我们人类的生存环境。

  In my opinion the rising water level of Qinghai has Both advantages and disadvantages, the benefits of Qinghai Lake is it would not have disappeared,If Qinghai Lake is too dry,it wiil be disppear after several hundred years , if a little moisture can be kept long, Qinghai Lake will exit.If the rising water level of Qinghai continues, eventually the water will take away part of the land eventually.(我认为青海湖水位上涨有好也有坏，好处是青海湖就不会消失了​，因为青海湖太干燥几百年后就会被晒干，如果潮湿一点就可以长久保存了。坏处是，青海​湖水位不断上涨，最终水会淹没一部分陆地。)

The effect of the Qinghai Lake in China

What role does Qinghai Lake play in our country? How will the rising water level affect ecological environment in our country?

青海湖在我国有着怎样的作用，水位上涨对我国生态环境会有什么样的影响？

• Qinghai Lake is the largest inland salt-water lake in our country which has a very important ecological position:It is the natural defence and climate adjuster of Qinghai-Tibet Plateau. Its environment influences the development of the province in the future. 青海湖是我国最大的内陆咸水湖，有着极其重要的生态地位：是青藏高原重要的生态屏障和​气候调节器，他的环境关乎着全省将来的发展。
  Apr. 08, 2009

   
  
  

• Ecologists praise the Qinghai Lake, as “the kidney of the earth”,” the kidney of the nature” and “the lung of the earth”, which is a natural barrier for preventing the desertification in the west from extending to the east，and it plays an important role in maintaining ecological balances of Qinghai-Tibet Plateau
  Apr. 08, 2009

   
  
  

• Lake does not exist, sandstorm from Chaidamu Basin will spread to greater part of China. And the north will become desert. As an important body of water for keeping the ecological security of the northeast part on the Qinghai-Tibet Plateau, Qinghai Lake is not only a natural barrier for preventing the desertification in the west from extending to the east, but also has an important impact on Yellow River valley. The rise of water level of Qinghai Lake will definitely have a great influence on ecological environment of our country even that of the globe.
  (青海湖对我国东部地区的环境有着保护作用，如果没有青海湖，柴达木的风沙会吞噬大半​个中国，我国北方将成为一片荒漠，作为维系青藏高原东北部生态安全的重要水体，青海湖​不仅是控制西部荒漠化向东蔓延的天然屏障，而且还会对黄河流域产生重要影响。青海湖水​位上涨无疑对我国乃至全球的生态环境都有重要影响。)

• Qinghai Lake in China plays a role in regulating climate. Qinghai Lake is China's impact on climate change.(青海湖在我国起着调节气候的作用。青海湖对我国的影响是气候会有所变​化。)
  Apr. 08, 2009

   
  
  

• Qinghai Lake is a climate of our country to protect God, he protects the north-east of the Qinghai-Tibet Plateau climate environment, but also of the Yellow River basin have a major impact. Qinghai Lake-bit up to our country and even around the world have an important impact on the ecological environment.
  
  青海湖就是我国的气候的一个保护神，他保护着青藏高原的东北部的气候环境，同时对黄河​流域也产生重要影响。青海湖水位上涨对我国乃至全球的生态环境都有重要影响。

The effect of the Qinghai Lake in the world

What role does Qinghai Lake play in the globe? How will the rising water level affect the globe?

青海湖在全球有着怎样的作用，水位上涨对全球会有什么样的影响

• Qinghai Lake is the important wetland of the world。And it is an important place that protect the world's biological diversity.青海湖是国际重要湿地。也是世界生物多样性保护的重要场所。

• Qinghai Lake natural reserve has a rising international stature and is attaching more and more importance from conservation international and from the governments at various levels. It is the largest inland salt water lake in China, and is a important place for protection of bio-diversity in the world, as early as 1992 it was included in the List of Wetlands of International Importance. It is famous Wetland Reserve in Ramsar Convention and is national natural reserve of China
  Apr. 08, 2009

   
  
  

• On July 30, 2007, special representative of former president Bush, Former Treasury Secretary Henry Paulson made Qinghai province as his first stop during his visit to China, and did a comprehensive survey to the ecological environment control of Qinghai Lake. There had never been such high-ranking international official paid special visit to Qinghai before. This explains that Qinghai Lake plays an important role in the world; I have seen this on the net, as early as 1992 Qinghai Lake was included in the List of Wetlands of International Importance. It was famous Wetland Reserve and national natural reserve of China in Ramsar Convention, therefore, I think Qinghai Lake plays an important international role, and rising water level of Qinghai Lake has a direct influence on global climate and environmental change.
  
  (前总统布什的特别代表、前财政部长保尔森将青海省列为访问我国的第一站，对青海湖生​态环境治理进行了全面考察。以前，还从来没有过国际上这么大的官到青海来专访呢，这就​说明，青海湖在国际上具有很重要的地位，我以前在网上也见到过，早在１９９２年青海湖​就被列入国际重要湿地名录，是《拉姆萨尔湿地保护公约》中著名的湿地保护区和中国国家​级自然保护区，所以，我觉得青海湖在国际上具有很重要的地位，青海湖水位上涨也直接影​响着全球气候和环境的变化。)

• Qinghai Lake is an important fishing area, the lake of grass are cattle, sheep, horse pasture essential. Bird Island has a variety of more than 160 kinds of birds, the world's most important biodiversity conservation sites, it has important ecological value.青海湖是重要的渔业区，湖边的草地时牛、羊、马的重要牧草地。鸟岛有各种​鸟类160多种，最为世界上生物多样性保护的重要场所，它有着重要的生态价值。

• I heard my uncle said that the Qinghai Lake's unique natural conditions make the Qinghai-Tibet Plateau in Qinghai Lake has become the protector of biological species database, which give scientists to carry out wetland biodiversity and bio-genetic research will provide a lot of help, therefore, known as the Qinghai Lake "Qinghai-Tibet Plateau gene pool", has a very high scientific value
  
  我听我伯伯说，青海湖独特的自然条件使青海湖成为青藏高原生物物种的保库，它给科学家​开展湿地生物多样性和生物遗传性的研究提供很大地帮助，因此，青海湖被誉为“青藏高原​基因库”，具有极高的科学研究价值
