It was a case study to use as a basic data for efficient the preservation and management of subalpine coniferous forest in national parks. It is based on inhabitation condition of 210 individuals of Abies koreana Wilson that was found through local investigation in the sub-alpine zone of Jirisan National Park and Songnisan National Park. It analyzed the effect of the geographical location and topographical features, which are the basics of location environment, on the growth of A. koreana. The variables related to the growth of A. koreana are tree height and diameter at breast height. Topographical features include geographical longitude, altitude above sea level, slope of the mountains, aspect that describes the direction in which a slope faces and topographical wetness index. Topographical features were extracted through GIS spatial analysis. It used canonical correlation analysis to estimate whether the two variables groups have related to each other and how much they are related, if any, and estimated the effect of the geographical and topographical features on the growth structure of A. koreana using multiple regression analysis. The tree height and diameter at breast height that represent the growth structure of A. koreana show greater relation to geographical latitude distribution than topographical feature and the geographical and topographical factors show greater relation to diameter at breast height than tree height. The growth structure's variable and geographical and topographical variable of A. koreana have meaningful relation and the result shows that geographical and topographical variables explain 18.1% of the growth structure. The variables that affect the diameter at breast height of A. koreana are geographical latitude, topographical wetness index, aspect and altitude, which are put in order of statistical significance. The higher the latitude is, the smaller the diameter at breast height. Depending on the topographical feature, it becomes bigger. The variable that affects the tree height is topographical wetness index, which was the only meaningful variable. Overall, the tree height and diameter at breast height that are related to the growth structure of A. koreana are affected by geographical and topographical feature. It showed that the geographical feature affected it the most. Especially the effect of water among the topographical features is expected to be bigger than the other topographical factors. Based on the result, it is expected that geographical and topographical feature is an important factor for the growth structure of A. koreana. Even though it considered only the geographical and topographical features and used spatial analysis data produced by GIS, the research results will be useful for investigating and researching the growth environment of coniferous forest inhabiting in sub-alpine zone of national parks and are expected to be used as basic data for establishing measures to efficiently manage and preserve evergreen needleaf tree such as A. koreana.

This study was carried out to identify the analysis of vegetation-environment relationships of the coniferous forests in subalpine districts of Mt. Chiri by two-way indicaton species analysis(TWINSPAN) and CCA. The results are summarized as follows; The subalpine coniferous forest in Mt. Chin was classified Abies koreana community group by the TWINSPAN method. The Abies koreana community group was classified Abies koreana-Pinus densiflora, Abies koreana-Quercus mongolicd and Abies koreana-Picea jezoensis. The Abies koreana-Quercus mongolica community classified into two subcommunities, typical and Pinus koraiensis subcommunity. The Abies koreana-Picea jezoensis community classified into three subcommunities such as typical, Taxus cuspidate and Cornus controversa subcommunity. The subalpine conifers commnities in Mt. Chiri could be classified into six vegetation units, which consisted of three vegetation communities and five subcommunities. The relationship between vegetation community and influencing environmental factors was analyzed by using the CCA ordination method. It was found that altitude, concentrations of $Ca^{++}$ and $Mg^{++}$ in soil were, major environmental variables, which influence the distribution of vegetation community in the first axis, and $Ca^{++}$ and altitude in the second axis. In the relations of communities and environmental factors by CCA, the optimal ecological habitats of Abies koreana-Pinus densiflora community could be located at low elevations, in which $Ca^{++}$ and $Mg^{++}$ are rich. Abies koreana-Quercus mongolica community prefers the sites in mid-elevation zone, in which $Ca^{++}$ and $Mg^{++}$ are medium level in soil. The optimum site for Abies koreana-Pinus koraiensis community and Abies koreana-Taxus cuspidata community could be high elevations in which $Ca^{++}$ and $Mg^{++}$ are poor. Abies koreana-Cornus controversa community is found in the site at low elevations where $Ca^{++}$ and $Mg^{++}$ are medium.

The purpose of this study was to investigate the damage caused by rodents in the area around Seseokpyeongjeon in Jirisan National Park and identify suspected perpetrating species by analyzing rodent excrement found near the damaged trees. Damaged trees were surveyed regardless of species of trees in the exploration trail in the target site where visual observation was possible. Sequencing analysis of mitochondrial DNA Cyt-b was performed on rodent excrement around the damaged trees to identify the perpetrating species. A total of 52 trees were damaged by rodents, and they were all identified to be Korean Fir (Abies koreana) and were concentrated in places where Korean Fir formed communities with high density. A total of 40 Korean Fir over 1.5 meters high were surveyed, and only the affected branches, not the whole tree, were found to be withered in 39 of them. A total of 12 Korean Fir under 1.5 meters high were surveyed, and 7 of which were found to have been completely withered, indicating that relatively young trees were more vulnerable to withering. The genetic sequencing analysis of excrement confirmed that the species that perpetrated the Korean Fir was Craseomys regulus.

This study was carried out to compare the diameter increment of Pinus densiflora for.erecta, Pinus koraiensis, Larix leptolepis, Abies holophylla and Abies koreana growing in middle area of Korea. The results obtained were summarized as follows; 1) The difference in annual diameter increment among five species according to D.B.H classes showed to be the strongest in Pinus koraiensis the second rank Larix leptolepis, the third rank Pinus densiflora erecta, the fourth rank Abies holophylla and the weakest in Abies koreana. 2) It was inferred that when the D.B.H of Pinus densiflora for.erecta comes to 95cm, Pinus koraiensis 80cm, Larix leptolepis 80cm, Abies holophylla 140cm and Abies koreana 85cm respectively, their diameter do not increase. 3) Total D.B.H increment among five species according to tree age classes were ranked as follows; Larix leptolepis, Pinus koraiensis, Pinus derasiflora for.erecta, Abies holophylla and Abies koreana. 4) It was inferred that when the age of Pinus densiflora for.erecta comes to 200yrs, Pinus koraiensis 120yrs, Larix leptolepis 120yrs, Abies holophylla 260yrs and Abies koreana 300yrs respectively, their diameter do not increase. 5) Abies koreana showed the lowest diameter increment in comparison with other four species, while diameter increment in Abies holophylla and Abies koreana decreased in later age than other species.
