Abstract:
The objectives of this research were to
survey and classify the forest area and study the
forest area change in Nongteng Sub-district, Krasang
District, Buriram Province during 20022014 by
using aerial photography recorded in 2002 and
satellite image detected in 2007 and 2014, to
classify the forest area by visual interpretation
method, and to analyze the forest area change in
20022014 using geographic information system by
overlay data method. It was found that In 2002,
2007 and 2014 there were 8.781, 8.586 and 7.985
square kilometers respectively, during 2002 2007
forest area decreased 0.195 square kilometers or
2.21 percent and changed to paddy field increased
0.095 square kilometers. During 20072014 forest
area decreased 0.601 square kilometers or 7 percent
and changed to rubber plantation increased
0.274 square kilometers. It was also found that
forest area increased 0.057 square kilometers in
Bancharn community forest. Forest area tented to
annually decrease at the average of 0.039 square
kilometers in 20022007 and at the average of
0.086 square kilometers in 20072014. This showed
that decreased rate of forest area was increased
from destroyed as a consequence of clearing and
farming. Most of the area were changed to paddy
field and rubber plantation.
