Abstract

This study was conducted to assess forest biomass resource which is a carbon sink and a renewable resource in Korea. The total forest biomass resource potential was 804 million tons, and conifers, broadleaved forest and mixed forest accounted for 265 million tons, 282 million tons, and 257 million tons, respectively. Proportionately to regional forest stocks, biomass potential of Gangwon-do had most biomass potential, followed by Gyeongsangbuk-do and Gyeongsangnam-do. The woody biomass from the byproduct of sawn timber in commercial harvesting was 707 thousand ton/year, and that from the byproduct of forest tending was 592 thousand ton/year. The amount resulted in about 1,300 thousand ton/year of potential supplies from forest biomass resource into the energy market. It's tonnage of oil equivalent(toe) was 585 thousand ton/year. In this study, we developed a program (BiomassMap V2.0) for forest biomass resource mapping. Used system to develop this program was Microsoft Office Excel, Microsoft Office Access ArcGIS and Microsoft Visual Basic 6.0. Additionally, This program made use of tool such as ESRI MapObjects2.1 in order to take advantage of spatial information. This program shows the map of total biomass stock, annual biomass growth at forest land in Korea, and biomass production from forest tending and commercial harvesting. The information can also be managed by the program. The biomass resource map can be identified by regional and forest type for the purpose of utilization. So, we expect the map and program to be very useful for forest managers in the near future.

본 연구는 탄소흡수원이며 재생가능한 자원인 산림 바이오매스 자원량 및 에너지로서의 잠재량을 산정하고, 이를 지도화 및 프로그램화 하고자 하였다. 2010년말 기준 우리나라 전체 산림의 총 바이오매스 자원은 804백만톤이며, 이 중 임상별로는 침엽수 265백만톤, 활엽수 282백만톤, 혼효림 257백만톤이 점유하고 있었고, 지역별로는 산림축적량에 비례하여 강원도가 가장 많은 바이오매스 양을, 다음이 경상북도, 경상남도 순이었다. 우리나라 산림에서 매년 상업적으로 벌채하여 제재목 등으로 이용되고 남은 목질부 바이오매스는 707천톤/년 정도가 되며, 숲가꾸기를 하여 원목으로 이용되는 양을 제외한 바이오매스 양은 592천톤/년으로 나타났다. 따라서 우리나라에서 연간 시장으로 공급 가능한 산림 바이오매스 자원은 약 1,300천톤/년 정도가 될 것으로 추정된다. 이를 석유환산량으로 전환하면 약 585천 toe/년이 된다. 본 연구에서 분석한 결과를 토대로 바이오매스 자원 지도 프로그램을 만들었다. 프로그램 개발하기 위해 사용된 시스템은 Microsoft Office Excel, Microsoft Office Access ArcGIS, Microsoft Visual Basic 6.0 이었으며, 공간정보를 활용할 수 있도록 ESRI MapObjects2.1 개발 도구를 이용하였다. 바이오매스 자원 지도(BiomassMap V2.0) 프로그램은 축적, 바이오매스 총 저장량, 시업지 연간 바이오매스 생장량, 상업적 벌채에 의한 바이오매스 생산량, 숲가꾸기에 의한 바이오매스 생산량 등을 지도로 나타내고, 이들 정보를 관리할 수 있는 프로그램이다. 바이오매스 자원 지도는 시도별, 임상별도로 확인할 수 있으며 이용자의 사용 목적에 따라 작성될 수 있다는 장점이 있다. 따라서 향후 본 바이오매스 지도는 산림이용 관리자들에게 유익한 정보를 제공할 수 있을 것으로 기대된다.
