. Conclusion
. Introduction
Runs from Mountain Baekdu to mountain Jiri which has been considered as a sentimental foundation of Korea
Symbol of Korean Peninsula
Back bone of Biosphere
Background
. Introduction
Understanding of importance of Baekdudaegan Mountain Region as a sentimental and ecological foundation of Korea
Recently, Increasing deforestation of Baekdudaegan Mountain Region
Considering a broad area of Beakdudaegan Mountain Region and temporal deforestation patterns, we need to analysis the region more widely.
We need to analyze quantitatively about deforestation and sustainable management, using satellite images and quantitative methods.
No quantitative researches about Baekdudaegan Deforestation areas
Background
Analysis of deforestation areas and spatial patterns of Baekdudaegan Mountain Region
Fundamental study for sustainable management of Baekdudaegan Region
Objectives
Period of Study
• The latter half of the 1980’s ~ the first half of the 2000’s (1989, 1998, 2002)

. Results
. Results
Built-up areas are composed of existing rural towns and roads, collective service-facilities areas.
Built-up areas have serious problems of forest discontinuation with point, line, and surface forms.
There are increasing crop fields and orchards close by built-up areas, especially hill areas deforestation is being aggravated.
Built-up
. Results
Agriculture areas are composed of existing fields close by rural town and highland vegetable growers.
There are increasing small-scale cultivation, vegetable garden and orchards close by rural town.
Highland fields are increasing in Gangwon-do and KyungSangbuk-do by agricultural policy of local self-government.
In Highland fields, the use of pesticides and fertilizers has been increased to maintain soil fertility and improve crop productivity.
Agricultural Area
. Results
Grassland areas are composed of pastures, natural grasslands and lands in fallow, cemetery parks et al.
Pasture areas show the largest deforestation patterns in Baekdudaegan Conservation Region.
Grassland
. Results
Bare land areas are composed of mining districts, campsites, slopes of road and facilities.
The most serious deforestation form is bared areas by mining and slopes
Slopes of roads are serious problem causing continuous soil erosion, topographic changes, and discontinuity of forest habitats.
Bare Land
The land use types in the Baekdudaegan Preservation Region were largely classified into urbanized/built-up area (residential, industrial, commercial, recreational, and public facility areas) including transportation area (expressways, national highways, and trails), agricultural area (rice paddies, agricultural fields, orchards, and so on), and bare land (mining areas).
The Results show deforestation areas are gradually increasing after 1980’s by detection methods of remote sensing and land cover classification.
- * -
. Conclusion
The largest deforestation area in the Baekdudaegan was found in where elevation is rower than 400m, slope below 20 degree, the areas less than 200m from roads and streams, and the deforestation areas located in more serous areas after 1980’s.
