Abstract

The aim of this study was to investigate the damage characteristics induced by winter freezing of evergreen broad-leaved trees distributed in urban area of warm temperate forest zone, which are gaining increased interest recently as climate change. The results of the study indicated that, as for 'stem injury', Camellia japonica Linne (59.6%) had the weakest damage, while Ternstroemia gymnanthera Sprague (83.3%) had the most severe damage. By the visual evaluation of freezing injury according to the characteristics of plantations environment, the observations of single planting (p<0.01) in planting method had weaker damage than those of group planting, the observations of under tree (p<0.001), plain (p<0.001), and organic matter plenty (p<0.05) in plantations characteristics had significant differences with relatively weaker damage than the observations of open space, slop, and scarcity, respectively. Tree height (-0.432) and crown width (-0.470) among growth factors were negatively correlated with the severity of damage, respectively. Therefore, the selection of tree species is vital for the successful creation of these urban forested area by making considerations of planting environment, and further research on evergreen broad-leaved trees is needed in this aspect.

최근 기후변화로 인해 관심이 증대되는 도시 녹지 내 난대상록활엽수의 동해피해 현황을 조사하여 그 특성을 분석하였다. 각 개체목의 주요 부위별 피해빈도를 분석한 결과, 줄기 피해는 동백나무가 59.6%로 가장 낮았으며, 후피향나무가 83.3%로 가장 많은 피해를 입은 것으로 나타났다. 피해도는 지역별로 진주지역이 가장 피해가 심하였으며(p<0.001), 식재구역의 경우 생태공원이 가장 높은 피해도를 보였다(p<0.001). 식재 환경별로 수하식재지(p<0.01), 단목식재(p<0.001), 평탄지(p<0.001) 및 유기물이 많은 곳(p<0.05)에서 피해도가 낮았다. 생육인자와 피해도와 간의 상관분석 결과 수고, 수관폭의 상관계수가 각각 -0.432, -0.470으로 피해도와 부의 상관관계로 나타났다. 따라서 효율적인 난대상록활엽수의 도시녹지 조성을 위해서는 수종, 입지환경 특성을 충분히 고려하여야 할 것으로 사료된다.
