Other Abstract  The Chinese people began to research on the main source of the Changjiang(Yangtze) River 2400 years ago.Limited by the scientific level,they did not discover it.
    The Tuotuo River was determined as the main source of the Changjiang River in the 1970s.However,this was not correct,because the glacier length in the front of headwaters Was added to the Tuotuo River,thus the Tuotuo River is 1 km Ionger than the Dam River,keeping in mind that the glacier can not be regarded as part of the river,when comparing the length of the Tuoyuo River with the Dam River.
    In the summer of 1986,we investigated the source of the Changjiang River,and accurately measured the length of both the Tuotuo and Dam rivers,We discovered that the Dam River was 353.1km long,and the Tuotuo River was 346.3km long.The Dam River is 6.8km longer than the Tuotuo River.The discharge of the Dam River is 196.18m3/s,and 2.6 times as large as the Tuotuo River(the Tuotuo River is 75.10m3/s).The drainage area of the Dam River is 1.8 times as length as the Tuotuo River:the drainage area of the Dam River is 30 715.7 km2.the Tuotuo River is i6691.0km2
     As mentioned above,we came to the conclusion that the main source of the Changjiang River is the Dam River instead of the Tuotuo River.
