First of all I would like to thank Mrs. Make and the organizing committee or having appointed me to serve as the chair of this conference.
We are now very close to the end of this conference. I believe that our conference is a great success. It went smoothly as scheduled. In these two days the conference has covered so many important and complex problems in the flied of global environmental change both theoretical and practical. All the presentations were very illuminating and informative. And the heated panel discussions were very stimulating and fruitful. Now with great joy and reluctant mind to part we get together again to declare that the conference has drawn to a successful close.
