Big and Old Tree is the natural heritage as well as the environmental index. Nevertheless ecological· cultural recognition of Big and Old Tree resources gets higher, however most of them suggested treatment plan through state investigation research, soil components, leaf or Cambium vitality degree analysis. Also, research on standing tree type analysis, location environment, or correlation with growth state, and designation of protected trees is still insufficient. Since research target is also focused on designated Big and Old Tree, accordingly, there’s no research on non-designated Big and Old Tree. This research aimed at investigating the state of Big and Old Tree in Changwon-si, and suggesting protected tree designation and sustainable preservation plan by analyzing location environment and management state. Since September, 2014, this research investigated distribution state, location environment, growth state, and management state by composing research target Big and Old Tree list. In respect of comparative analysis of investigation items by dividing into two groups, i.e. designated Big and Old Tree and non-designated Big and Old Tree, this research conducted investigation until August, 2016. As the research result, in Changwon, there are 92 units of protected trees, 4 units of natural monument, 1 unit of Gyeongsangnamdo monument, and 87 units of Changwon protected trees, and other non-designated 145 units of Big and Old Tree. Big and Old Tree of Changwon were mostly planted trees than natural standing trees. Designated Big and Old Tree were mainly in inland-center, while non-designated Big and Old Tree were evenly distributed inland-center-coast. Standing types are more in multi-standing than simple granule, and in pairs Tree, Big and Old Tree were densely distributed. Types of trees were 78 of Muku Tree, the most, compared to 57 of Zelkova, 39 of hackberry, 13 of Pine, and 9 of Asian hornbeam. This is because there are lots of Muku tree genius loci tree · supplement forest. Average scale of designated Big and Old Tree(breast height circumference) is 389,77㎝, bigger than 372,16㎝ of non-designated Big and Old Tree. However, the average scale of Muku tree, Pine, Red Leaf Willow, and maximum scale of Hackberry, Asian hornbeam, Pine, Red Leaf Willow, and Carster Aralia appeared bigger in non-designated Big and Old Tree. Bukburi hackberry had bigger diamter at breast height by 15 cm than Gochang Sudong-ri Hackberry, domestic biggest scale natural monument no.494, while Chusan-dong Carster Aralia appeared bigger than natural monument no.164 Sinbangri Carster Aralia by 40cm. There’s a problem to designate protected trees mainly with Big and Old Tree with good accessibility without precise investigation on Big and Old Tree resource. Changwon Big and Old Tree are mainly distributed in residential area, farmland, mountains, and streams. Many of them are distributed in slope, projecting area than flat land. Designated Big and Old Tree are stood close to the road, while non-designated Big and Old Tree to the streams. This research analyzed the location topography, land use state, surrounding state (road, stream, residence, etc.), and the base situation, etc. As the result, non-designated Big and Old Tree location environment appeared ‘good’, however non-designated Big and Old Tree appeared within ‘normal’ scope, since they approached to the road, building· structure in the open space. Index of planting area appeared in order of grass land, bare land, and paved land, 186 units(78.48%) remained with the original ground. Type of tree, state, and growth state of root, stem, branch, and leaf indicated ‘normal’ in case of designated Big and Old Tree, while ‘good’ in non-designated Big and Old Tree. Among 92 units of designated Big and Old Tree, 49 units(53.26%), and 10 units(6.89%) of 145 units of non-designated Big and Old Tree) had surgery. The point that surgical rate gets high as the ground state and permeability are poor appeared in common in both groups. Progress of sate declination or withering(枯死) appeared higher in artificial cause(80%) than natural cause, and road extension appeared the biggest factor. Adaptability to growth ground change appeared high in Pine, Japanese Black Pine, and ginkgo tree, while appeared low in Asian hornbeam, and Muku tree. Stem humps mainly around the root part are presumed to be greatly influenced by the hard lower ground(硬質), such as rock, split land, and stonework, etc. Zelkova are densely distributed in Sodab-dong, Jindong-myeon, and Woongcheon-dong, where the old governmental offices were located, however growth state is below ‘normal’, which is determined due to the environmental change along with urbanization. Big and Old Tree, which stand in pairs Tree(雙樹) or group rather than single standing(單木) or that have succession tree, separated from residence, showed higher health or survival. On the other hand, Big and Old Tree with high awareness · placeness, or humane environment as religious purpose, ritual ceremony, and originated legend, etc. were advantageous in long-term growth due to high preservation consciousness. The point of poor location environment and growth state of designated Big and Old Tree) is considered due to excessive development for visitors after designation of protected trees as Big and Old Tree with good accessibility. Accordingly, a result was derived that non-designated Big and Old Tree can maintain favorable growth state due to high location environment with good natural property and less exposure to obstruction. Changwon Big and Old Tree have problems such as excessive reliance on surgical operation or trunk injection, excessive installation of pavilion or sporting goods, non-permeability pavement, Japanese style landscape stonework, etc. Also, protected trees are designated by residents’ application, accordingly, excellence· rarity· ecological value are not reflected due to designation of protected trees upon residents’ application. It is necessary to perform regular total inspection and evaluation of Big and Old Tree, and a procedure to designate protected tree by experts should be prepared. Also, it is necessary to arrange enough growth space, succession tree cultivation, and ecological preservation management. Henceforth, the researcher considers it is necessary to develop a manual to effectively apply to protected tree designation and management by quantifying ecological and cultural value of Big and Old Tree, such as natural resource, healthiness, landscape, cultural property, sustainability, etc. ，韩语论文网站，韩语论文 |
