ACKNOWLEDGEMENTS

This study has been supported by VIETNAM NATIONAL UNIVERSITY OF

FORESTRY. I would like to express my sincere gratitude to my advisor Dr. Le Xuan Truong

for the continuous support of my student thesis study and research, for his motivation,

enthusiasm, and immense knowledge. He was always able to answer any questions that I had.

If I didn‟t understand something the first time, he would explain it to me again so I would

understand it. With his guidance helped me in all the time of research and writing of this thesis.

I wish to thank professor from Colorado State University, Prof. Dr. Lee Macdonald. A

special man that I was very impressed during the study here. He always smiling, patience, and

providing my class with an excellent atmosphere for my our lesson as well as for my research.

And for my friend, I would like to many thank Mr. Tran Thanh Quang, he very nice and so kind.

He helped me a lot during assisting in the field work, it's very difficult work to collect data.

And most of all, thanks to my university, help me get these favorable conditions and

suitable environment to complete my research.

ABSTRACT

Estimation of forest canopy cover has recently been included in many forest inventory

programmes. In this study, after discussing how canopy cover is defined, different ground￾based canopy cover estimation techniques are compared to determine which would be the

most feasible for a large scale forest inventory. to quantify canopy cover and the estimates

they provide vary greatly. In this here, to collect the data we use three main method for

estimating canopy cover ratio (Differences in cover estimates among the ground-based

methods were not related to stand-structure type p = 0.33). As expected, estimates of cover

increased and stand-level variability decreased with increasing angle of view among

techniques.

The results indicate that different techniques yield considerably different canopy cover

estimates and through result of compare we can choose a suitable method and most accurate

for measuring forest cover.
