Introduction to the Lecture:

With regard to the problems in understanding the spatio-temporal variability of the geomorphological system, the report, by taking the river geomorphological system as an example, elaborates the development process of establishing the variational method to reveal the automatic shape adjustment mechanism of alluvial river channels, and tests the practical application of the constructed river evolution balance theory to identify the formation mechanism of different channel types and the action degree of control variables. In addition, in the light of the research progress in analyzing the development mechanism and main control factors of sandstone geomorphology landscape in the Zhangjiajie World Geopark, the future development direction of geomorphology system evolution theory and method is discussed.

Profile of the Speaker:

Huang Heqing, Ph.D., Researcher of the Institute of Geographic Sciences and Natural Resources Research, Chinese Academy of Sciences (CAS), Professor and Doctoral Supervisor of the CAS, and winner of National Science Fund for Distinguished Young Scholars. He has long been engaged in research on the mechanism and mode of automatic shape adjustment of alluvial river channels, the theory and method of geomorphological system evolution, the variation characteristics of water and sediment flux in river basins, the application of remote sensing technology in geomorphological system evolution, etc. Meanwhile, he has been actively participating in scientific research and popular science promotion of geomorphological relics in world geoparks.
