Abstract

The purpose of this study is to provide the basic data by analyzing and analysing the Growth Conditions of old Trees in Yangdong village. This study investigated about the conducted on tree information, soil information, and tree health. The result are as follows. The trees information in Yangdong Village consists of Juniperus chinensis, Salix chaenomeloides, Salix pseudolasiogyne, Celtis sinensis, Zelkova serrata, Gleditsia japonica, and Gleditsia sinensis trees, The range of height was 4.0~17.0m, and the diameter was 0.51~1.34m, Juniperus chinensis trees of No.17 was most large. In the results of soil analysis, there showed that acidity was pH4.1~6.3, hardness of 5~48mm, organic matter content of 21.2~29.1g/kg, electrical conductivity(EC) of 0.34~1.76dS/m, available P2O5 of 79.8~451.6mg/kg, exchangeable K of 0.22~1.71cmol+/kg, exchangeable Ca of 4.98~7.44cmol+/kg, exchangeable Mg of 0.67~2.19cmol+/kg, exchangeable Na of 0.19~1.04cmol+/kg and cation exchange capacity(C.E.C) of 7.23~13.02cmol+/kg. As a result, the highest number of tree health levels is 8 of 11trees of Celtis sinensis, 2 of 7trees of Zelkova serrata, and 3 of Gleditsia sinensis, and 13 of 30 trees of health levels, The Older trees with high infection, spoil and hollowed part were the remaining trees except for the healthy part. Relatively, more than half of the number of targets is infected, decay, and the hollowed site, and it is necessary to perform surgery on the damaged area. In addition, preservation and protection measures should be implemented by supplying root nutrients for trees, controlling nutrients in the body to prevent secondary and tertiary damages that cause the infection site to metastasize to the health site, In order to continually monitor the trees, measures to improve the location environment and management of the trees should be sought.

본 연구는 양동마을에 분포하는 노거수를 생육실태 및 분석하여 기초자료로 제공하기 위한 목적이 있다. 조사항목은 수목정보, 토양정보, 수목건강도에 대해 조사하였다. 연구결과를 요약하면 다음과 같다. 양동마을 내 수목정보는 향나무, 왕버들, 능수버들, 팽나무, 느티나무, 주엽나무, 조각자나무로 총 7종 30주이며, 수고는 4.0~17.0m, 흉고직경은 0.51~1.34m로 17번 향나무가 가장 넓었다. 토양분석 결과로는 산도 pH4.1~6.3, 경도 5~48mm, 유기물함량 21.2~29.1g/kg, 전기전도도 0.34~1.76dS/m, 유효인산 79.8~451.6mg/kg, 치환성 칼륨 0.22~1.71cmol+/kg, 치환성 칼슘 4.98~7.44cmol+/kg, 치환성 마그네슘 0.67~2.19cmol+/kg, 치환성 나트륨 0.19~1.04cm ol+/kg, 양이온치환용량 7.23~13.02cmol+/kg으로 나타났다. 이에 따라 수목건강도의 건강수치 중 가장 높은 노거수는 팽나무 11주 중 8주, 느티나무 7주 중 2주, 조각자나무 3주로 전체 30주 중 13주이며, 감염과 부패 및 공동수치가 높은 노거수는 건강수치를 제외한 나머지 수목으로 나타났다. 상대적으로 대상 노거수의 절반이상이 감염·부패 및 공동부위로 차지하고 있는 실태로, 손상이 부위는 외과수술을 진행할 필요가 있다. 또한 감염부위가 건강부위로 전이가 되는 2·3차 피해가 발생하지 않도록 수세회복을 위한 뿌리영양공급 및 체내 양분조절을 통해 보존보호조치가 시행되어야 하며, 지속적인 수목 모니터링을 노거수 입지환경개선 및 관리방안이 모색되어야 할 것이다.
