Abstract

This study aims to identify appropriate tree species and crops for agroforestry target sites in North Korea based on ecological geography and site properties. To this end, an ecological geographic map (13 regions and 4 zones) of North Korea was made using satellite images and North Korean academic journal articles. The target agroforestry sites were selected and mapped according to 18 site conditions depending on 3 site characteristics, and the sites were divided into short-term and long-term target sites depending on the agroforestry management period. Finally, optimal combinations of 30 tree species and 19 crops were selected by overlapping the ecological geographic map and agroforestry target site map. For regions within the same zone, tree species and crops were almost similar; however, compared to regions in other zones, they differed. This is likely because the geographical climatic characteristics reflected in the ecological geographic map vary greatly from zone to zone. These results will be used to propose a combination of suitable tree species and crops that takes into account both management purposes and management types for inter-Korean forest cooperation in the agroforestry sector.

임농복합경영에 관한 기술협력은 남북 산림협력 분과회담 주요의제 중 하나이다. 본 연구는 북한의 생태지리 및 입지 특성을 반영한 임농복합경영 대상지에 따른 적정 수종과 작물을 선정하기 위해 수행되었다. 생태지리구획도는 북한의 위성자료와 문헌자료를 사용하여 북한 전역을 4지대 13지역으로 구분하여 작성되었다. 북한 전역을 세 가지 입지 특성(토심, 경사 및 지형적 위치)에 따라 18개 입지 조건으로 구분하고, 북한의 임농복합경영의 경영기간에 따라 단기와 장기임농복합경영 대상지로 분류하여 지도로 작성하였다. 최종적으로 생태지리구획도와 임농복합경영 대상지 지도를 중첩하여 수목 30종과 작물 19종을 대상으로 지역별 적정 수종 및 작물을 분류하였다. 수종과 작물은 동일 지대 내 지역별로는 대부분 유사하였으나, 지대별로 비교했을 때는 차이를 보였다. 이는 생태지리구획에 반영된 지리 기후적 특성이 지대별로 큰 차이를 보이기 때문인 것으로 보인다. 향후 본 연구 결과를 기반으로 임농복합경영 분야 남북 산림협력 시 경영 목적과 경영 유형을 모두 고려한 수종 및 작물을 제안할 수 있을 것으로 판단된다.
