【答案】 Yangtze River is the Chinese first perpetual flow, is the world third perpetual flow .2001 years, Chinese Academy of Science Remote sensing Application Research institute in expert Liu Shaochuang under the management, the use satellite remote sensing phantom surveying putation, after the measurement result arrived the decimal point precisely.Determines the Yangtze River length 6211.3 kilometers.Its topic group uses near 40 to cover the Yangtze River main current the satellite phantom, the satellite phantom is by the US earth resource satellite photography, the resolution amounts to 30 meters.The puting mode by along the river course middle line, to has been gauging to Yangtze River three, also has gauged reverse three, operates and the geometry many times after the puter corrects obtains the result. This research, by when the tune took the Yangtze River source reckoning, makes concrete for works as the tune source position east longitude 94 ' 35 '' 54 seconds, the north latitude 32 ' 43 '' 54 seconds, the elevation 5042 meters calculate.When the tune (by source to the pouch Pakistan Gansu 360.8 kilometer, tuo the Tuo River 357.6 kilometers, passes the Milky Way extremely) 787.7 kilometer, Yangtze River 2322.2 kilometer, the Ipin following 2740.6 kilometers,Our general name 6300 kilometer or 6370 kilometers.The basin total area 180 ten thousand square kilometers, the annual mean enters the sea water quantity approximately 9600 hundred million cubic meters.The basin is situated between the north latitude 24°30 ' ~35°45 ', the east longitude 90°33 ' ~112°25 ', the area 180 ten thousand square kilometers (including the Huaihe River basin), do not approximately pose the nation total acreage 1/5.Occupies world 3rd.It is well-established, with Yellow River together, bees the Chinese nation the cradle, has nurtured generation of generation of China's youth, by the reputation is the mother river.
