Abstract

This study was carried out to provide basic data for active control of the anticipated damage through investigation and analysis of geographical and spatial occurrence distribution of oak wilt disease area. The damage of oak wilt disease was analyzed by investigating all the damage trees caused by oak wilt disease from 2011 to 2015 in three areas of Gwangtan-myeon, Paju-si, Gyeonggi -do. As a result, the closer to the ridge the more damage of the oak wilt was generated. Therefore, it is necessary to select the central management area from 0 to 40 m based on the ridge line for more effective control, and to intensively control the area. Also, it is difficult to predict the occurrence of damage by the slope because the damage situation represent differently by the region. By the diameter class, it was analyzed that the number of damaged trees was the largest in the average diameter class with the most number of the trees in each region.

본 연구는 참나무시들음병 발생지역의 지형적, 공간적 발생분포에 대한 조사와 분석을 통하여 피해 예상지에 대한 적극적인 방제를 위한 기초 자료를 제공하고자 수행되었다. 참나무시들음병 피해는 경기도 파주시 광탄면 3개 지역에서 2011년부터 2015년까지 발생된 피해목을 모두 조사하여 분석하였다. 그 결과 참나무시들음병은 능선에 가까울수록 많은 수의 피해목이 발생되었으며, 보다 효과적인 방제를 위하여 능선을 기준으로 0~40 m까지 중점관리지역으로 선정하여 집중적인 방제작업이 필요할 것으로 사료된다. 또한 경사에 따른 피해상황이 지역에 따라 다르게 나타났으므로 피해발생을 경사도로 예측하기는 어려울 것으로 판단된다. 경급별로는 지역마다 본수비율이 가장 높은 평균 경급에서 피해목의 수가 가장 많은 것으로 분석되었다.
