ACKNOWLEDGEMENTS

I would like to express my great appreciation to Assoc. Prof. Dr. Tran Quang Bao

from Vietnam Forestry University, my research supervisor, for his enthusiastic

encouragement and useful critiques on this research. Without his thoughtful and patient

guidance through every step of my research and her knowledge on how to correct and analyze

the data I collected, this thesis could not be completed. I also would like to say thanks to

lecturers, who have taught us for more than 4 years, and to the cooperation of Vietnam

Forestry University and Colorado State University, especially, the faculty of Forest Resource

and Environmental Management. I would like to extend my gratefulness to Mr.Sam Van

Thiet, the Chairman of Chau Hanh People’s Committe for accepting my research in Chau

Hanh commune.

And, I would like to express my gratefulness to Mr. Dang Manh Hung, the Head of

Quy Chau Hydrology Station, Department of Natural Resources and Environment, Nghe An

Province, Vietnam for providing information and documents.

Last but not least, I wish to thank Dr Bui Van Nang and Ms Nguyen Thi Ngoc Bich of

the Center of Laboratory and Practice of Vietnam Forestry University for providing me with

the measure instruments and helping me measure the indicators to complete my thesis.
