黄河源头

研究结果发现，从黄河源头至入海口，黄河水具有稳定同位素比率逐渐增大而3H浓度逐渐下降的趋势；

From the river source to the estuary , the ratios of the H and O isotopes are increasing and 3H concentrations are decreasing progressively .

兰州以上黄河源头地区河水的δ18O、δD的季节性变化与雨水相反，地下水对河水的补给贡献旱季大于雨季。

In the river source above Lanzhou , the seasonal variation of δ 18O and δ D in river water is different from that in precipitation . The percentage of groundwater contribution to river in dry season is larger than that in rainy season .

在自己的水泥房子里，她仍然可以看见银色的黄河源头，但是她和这边土地和水的关系，已经永远地被切断了。

From her concrete home , Zhuoma can still see the silvery beginnings of the Yellow River , but her relationship to the water and the land to her heritage has been lost forever .

草地对环境和水源保护有重要作用，因此长江和黄河源头地区退化草地的治理与流域生态安全和经济发展关系密切。

Concerning the grassland functions on environment protection and water head conservation , the management of degraded grassland in the headwater areas of the Yangtze , Mekong and the Yellow River is highly related to the whole watershed 's eco-security and economic development .

黄河源头区西部虽然水土流失面积较小，但生态十分脆弱，成土缓慢，土壤抗侵蚀能力差，一旦水土流失发生、发展极难重建和恢复。

The area of soil erosion in western part of the headstream basin is relatively small , but it still poses a serious threat to the ecological stability of the basin , which is a fragile area and in which rehabilitation after major erosion is very difficult .

资料显示：全世界到过珠峰有两万人，到过黄河源头有500人，而到过长江源头的只有150人。

According to records that throughout the world there are 20,000 people who have ascended the Everest , about 500 people who have been to the headwaters of the Yellow River , and however , only 150 people who have been to the headwaters of the Yangtze River .

因此，保护黄河源区生态环境、建立黄河源头特殊生态功能保护区已刻不容缓。

It is , therefore , of great urgency protect the eco-environment of the source region of the Huanghe River by means of setting up a special ecological function reserve .
