Abstract

It is necessary to set a management period by analyzing growth trends for individual species because the time taken for planted trees to become established differs by species. The purpose of this study was to suggest an appropriate management period through the analysis of the annual growth of Pinus densiflora planted in the riverine eco belt. The average annual growth before planting was 0.6cm. The growth after planting showed an increase of 0.3cm in the 1st and 2nd year, 0.5cm in the 3rd and 4th year, and 0.7cm after the 5th year. Since P. densiflora was confirmed to go through poor growth stages in the 1st and 2nd year, a recovery stage in the 3rd and 4th year, and a normal growth stage in the 5th year, management should pay more attention to improve inappropriate environmental conditions until at least the 4th year, unlike the growth of hardwood. Since the period required for activation by species may vary, the management period of each species will need to be set through growth research.

식재된 수목이 활착되기 위해 소요되는 시간은 수종별로 차이가 있기 때문에 개별 수종에 대한 생장량 변동 추이 분석을 통해 관리 기간을 설정할 필요가 있다. 이에 본 연구는 수변생태벨트 조성 지역에 식재된 소나무의 연간 생장량 변화 분석 자료를 바탕으로 관리 기간을 제안하고자 하였다. 생장량을 분석한 결과, 식재 전에는 평균 0.6cm, 식재 후 1~2년차 0.3cm, 3~4년차 0.5cm, 5년차 이후에는 약 0.7cm 내외였다. 식재된 소나무의 생장량은 1~2년차 생장 불량, 3~4년차 회복 단계를 거쳐, 5년차부터 정상 생장 단계가 확인되었기 때문에 활엽수와는 달리 최소 4년은 집중관리가 필요한 기간으로 판단되었다. 수목별 활착에 필요한 기간은 차이가 있을 수 있기 때문에 생장량 연구를 통해 수종별 관리 기간을 설정해야 할 것이다.
