Abstract

This study was conducted to analyze the forest status and deforestation area changes of the DMZ region in North Korea based on satellite images. Using growing and non-growing season's RapidEye satellite images, land cover of the North Korean DMZ was classified into stocking land(conifer, deciduous, mixed), deforested land(unstocked mountain, cultivated mountain, bare mountain), and non-forest areas. Deforestation rates in the Yeonan-baecheon, Beopdong-Pyeonggang, Heoyang-Geumgang and Tongcheon-Goseong district were calculated as 14.24%, 16.75%, 5.98%, and 16.63% respectively. Forest fire and land use change of forest were considered as the main causes of deforestation of DMZ. Changes in deforestation area were analyzed through Google Earth images. As a results, it was shown that the area of deforestation was on a decreasing trend. This study can be used as basic data for establishing inter-Korean border region's forest cooperation strategies by providing forest spatial information on the North Korea's DMZ.

본 연구는 위성영상을 바탕으로 북한 DMZ의 산림현황을 분석하고 산림황폐지의 변화를 분석하기 위해 수행되었다. 생육기·비생육기 RapidEye 위성영상을 활용하여 북한 DMZ의 토지피복을 분류하였다. 토지피복을 입목지(침엽수림, 활엽수림, 혼효림), 산림황폐지(산간나지, 개간산지, 무립목지), 비산림지로 분류하고 산림 및 산림황폐지 면적을 생태지리구획에 따라 집계하였다. 연안-배천지구, 법동-평강지구, 회양-금강지구, 통천-고성지구의 산림황폐율은 14.24%, 16.75%, 5.98%, 16.63%로 각각 산출되었으며, 북한 DMZ 내 산림황폐화 주요 원인은 산불과 산지전용으로 판단되었다. 또한, 구글 어스 영상을 통해 산림황폐지 변화를 분석하였으며, 산림황폐지 면적은 감소하고 있는 것으로 확인되었다. 향후 본 연구 결과는 북한 DMZ의 산림공간정보를 제공함으로 써 남북접경지역의 산림협력 전략 수립을 위한 기초자료로 활용될 수 있을 것이다.
