초록

본 연구는 산림 내에서 수종갱신 및 천연갱신 등의 산림시업을 실시한 이후 딱정벌레류 곤충분포상의 변화 양상을 군집수준으로 조사 분석하여 종다양성이 증대되는 시업방법의 구명을 통해 산림생물다양성 보전을 위한 효과적인 관리기법을 제시하는데 필요한 기초자료를 확보하고자 수행되었다. 이를 위해 2012년, 강원도 삼척군 하장면 일대의 소나무림 갱신임지 내에서 5개의 임업시업 방법별로 처리한 후 동일지점에서 2013년 7월부터 10월까지 딱정벌레류 곤충상 조사를 실시하였다. 조사 목적상 갱신임지 유형별로 딱정벌레류를 정량조사하기 위해 45일 간격으로 린드그렌 퍼넬트랩을 이용하여 채집조사를 실시하였으며, 조사대상인 딱정벌레류의 분류군별 다양도 및 풍부도를 중심으로 분석을 실시하였다. 연구 결과, 딱정벌레류는 총 40과 156종 1,112개체가 조사되었다. 조사 초기 단계에서 각 처리방법별 뚜렷한 밀도차이는 나타나지 않았으나, 전 처리구들이 대조구에 비해 다양도 및 풍부도가 증가하는 경향을 보였고, 이 중 대상개벌을 실시한 구간에서 비교적 높은 밀도를 보이는 것으로 확인되었다.

This study was carried out to investigate the changing pattern of forest insect communities in 2013 after harvesting of forest in 2012, and provide a basic data for the method of efficient management for preservation of forest biodiversity. Five types of cutting method in pine tree forest were selected to compare the coleopteran insect communities at Hajang-myeon, Gangwon-do, Korea, in 2013. In this study, we investigated the effects of timber harvest with green-tree retention on coleopteran insects. They were sampled with Lindgren funnel traps for five experimental sites during July to October, 2013. A total of 1,112 individuals in 156 species of 40 families by Lindgren funnel traps. Also, the analysis of coleopteran insects community was performed. Although the difference of density is not prominent among the survey areas in the early stages, it was appeared a tendency to increase in density and abundance of insects in the experimented sites excluding the control areas. Among them, strip clear-cutting area showed a increase of density and abundance in this study.
