본 연구는 광주광역시에 분포하는 보호수 및 노거수의 분포 및 생육현황을 조사하여 보호수와 노거수 관리방안을 제시하고자 시도하였다. 광주광역시에 분포하는 보호수는 9종 68개체로 이 중 광산구가 18개체로 가장 많았으며, 노거수는 10종 155개체로 확인되었다. 기존문헌에 잘못 기록된 종명은 정확한 식물명으로 수정되어야 한다. 보호수의 활력도 평균은 1.2였으며 지면상태 평균은 1.7이었고 노거수의 활력도 평균은 1.3, 지면상태 평균은 2.0으로 활력도는 큰 차이가 없었고 지면 상태는 노거수가 조금 더 좋지 못한 것으로 나타났다. 활력도가 3.2~4.0범위를 보여 절대관리가 필요한 보호수는 광산구 송대동 대촌마을 은행나무 1개체 이었고, 노거수는 광산구 산수동 감동마을의 왕버들 1개체로 나타났다. 보호수 및 노거수의 관리방안에서 제일 중요한 것은 기본적으로 노거수가 자랄 수 있는 최소한의 생육공간을 확보하는 것으로 보호수와 노거수 근계 위의 아스팔트나 시멘트 포장을 제거해 주어야 한다고 판단된다.
This study aims tried to present develop a management plan for about old and big trees and legally protected trees by investigating through the present the current status and the distribution of the legally protected trees and old and big tree that range in Gwangju, South Korea. The number of legally protected plants that distributed in Gwangju City is 68 individual trees from 9 species. The largest number was found in Gwangsan-gu (18 trees). The total number of the old and big trees that are distributed in Gwangju City was confirmed as 155 individual trees from 10 species. It must to be corrected to a correct plant species name that species name is written in review articles incorrectly. The average vitality rate of the legally protected plants was 1.2 and the status of ground was 1.7 on average. And the vitality rate of the old and big trees was 1.3 and the status of ground was 2.0 on average. Vitality are not significantly different between the legally protected trees and old and big trees. Ground status of old and big trees worse than legally protected trees. Gingko biloba (found in Gwangsan-gu Songdaedong Daechon village) was only legally protected plant that requires urgent management due to low vitality rate (between 3.2 and 4.0). Among old and big trees Salix glandulosa which is found in Gwangsan-gu Sansu-dong Gamdong village was only one that requires urgent care. The most important status for the old and big tree is securing minimal space for growth. Therefore, we conclude that the most urgent measure in the management and projection of old and big trees and legally protected plants is removal of asphalt or cement above the surface of root system.
