Biography

Yuan Daoxian, male, Han nationality, is a native of Zhuji, Zhejiang Province. He graduated from the Nanjing Technological Academy of Geological Surveys in 1952.

From the 1960s to the 1970s, Yuan Daoxian proposed the most essential features of karst underground water is that the asymmetry of water-bearing medium led the hydrogeologic prospecting in the karst area. During the 1980s, Yuan built up the karst hydrogeologic test field and carried out the systematical study of hydrodynamic fields, temperature fields, chemical fields, setup the movement mechanism of underground water in gas zones, and created mathematical models of adjustment and storage functions. At the same time he summarized the basic features of aerial karst in China and carried out the comparison of karst throughout the world.

Yuan studied the geochemistry of karst and summarized the geochemical mechanism of open systems and semi-opened and semi-closed system karst growth in China. He verified the supply way of the Baotu Fountain by the karst geochemical field and tracer technologies. He also introduced earth system science into karst science, researched the relationship between the karstification and global carbon circulation, studied the variation in the world by the stalagmite information, and proposed karst dynamics.

Yuan is an academician of the Chinese Academy of Sciences.
