The 4th China – Japan – Korea International Workshop on Present Earth Surface Processes and Historical Environmental Changes in East Asia “Modern Lake-Catchment Processes and Human Activity in East Asia” takes place 17-21 September 2007.


The purpose of the China-Japan-Korea (CJK) Workshop is to exchange modern and historical environmental information in East Asia region for clarifying environmental processes and changes since the last interglacial in East Asia. The CJK International Workshop was initially held in Daejeon, Korea (2004), and was subsequently in Kanazawa, Japan (2005) and Seoul, Korea (2006). Since the 4th workshop, it will be held in China, Japan and Korea by turns, and the workshop theme will be decided by the host, which was a key agreement of the 3rd workshop in Korea. The theme of 4th workshop will be “Modern Lake-Catchment Processes and Human Activity in East Asia”.

As a part of continental hydrosphere, lake is closely related with the atmosphere, biosphere and lithosphere, being a conjunction of the above spheres. The lacustrine sediment, with the advantages of continuous record, high resolution, abundant environmental information and widely geographical distribution, recorded faithfully the global, regional and local signals of environmental evolution, and is the archive of regional difference of water and heat balances. Additionally, lacustrine sediments preserved abundant information of interaction between human activities and natural processes, because lake catchment is used to be concentrated places of human beings for its abundant fresh water resources, plenty products and feasible climate conditions. Thus lake sediment, as an informative carrier, plays an important role in past global change research and shows more and more advantages and potentiality in management and restoration of lake-catchment environment.

There is a long history of civilization in East Asia, where human activity has undergone the process from acclimating to altering the nature, correspondingly the lake-catchment ecological processes has changed from nature-dominated to human-dominated. Studies on paleo-environmental change clarify the process of the ecological response to human activity and natural variation and their interactions, and provide the basis to project environmental scenario in future. Studies of the modern lake-catchment process provide the useful approaches on reasonable interpretation of sediments proxies, quantitative reconstruction of paleo-environmental change and effective distinguishing the human impact on environment and ecologic system.

Main topics

  1. Present lake-catchment processes: Observational results and Interpretation;
  2. Present process and environmental proxy transformation function;
  3. Lacustrine sediment choronology;
  4. High resolution records of environmental changes;
  5. Ecological response to human activity and natural variation and their interactions;
  6. Regional comparison of historical environmental change;
  7. Modeling for mechanism of environmental change and forecasting environment change tendency;
  8. General discussion and some topics for the future cooperation.
