长江源有三个源头,分别为北源楚玛尔河、正源沱沱河、南源当曲,流域面积十余万平方公里。长期以来,国人能见到的江源影像并不多,这主要是由于那里地处高原寒漠陷阱重重,大部分地方是无人区,很多地方不仅是科学考察的空白区,也是影像记录的空白区。1986年和1993年,我曾去过各拉丹冬,姜古迪如冰川,这里是沱沱河的发源地,过去的20年中,当曲源和楚玛尔河源很少有人涉足。2006年夏季和2007年冬季,我分别带队进行了长江源区地毯式考察,这样的行动让很多朋友担忧。两辆越野吉普、一艘漂流船,还有些简陋的户外装备。
There are three sources of the Yangtze River source, respectively, the north of the Chumar River, is the source of Tuotuohe, Nan Yuan Dangqu, the drainage area of more than 100,000 square kilometers. For a long time, there are not many rivers and rivers that people can see. This is mainly because there are many cold-trapped places in the plateau. Most of the places are unmanned areas. Many places are not only a blank area for scientific investigation, but also an image record Blank area. In 1986 and 1993, I went to Lhasa Dongdong and Giangguddy, such as the glacier, where the Tuotuo River originated. For the past 20 years, there were very few people in Quyuan and Chumar Heyuan. In the summer of 2006 and the winter of 2007, I led a carpet inspection of the Yangtze River source area respectively. Such actions have caused many friends’ worries. Two off-road jeeps, a drift boat, and some rude outdoor gear.
