산림생태계의 생물다양성 보존 및 서식지 복원을 위한 연구 : 구상나무림을 중심으로 = An Eco-genetic Study for Biodiversity Conservation and Ecological Restoration of Endangered Forest Ecosystem

다국어 초록 (Multilingual Abstract)

Abies koreana Wilson is an endemic conifer species in Koeaa. Its natural distribution is restricted to the subalpine areas of the southern high rising mountains such as Mt. Halla, Mt. Jiri and Mt. Dukyu. Recently, the decline in growth of A. koreana became obvious and it appears to be a serious problem for maintaining the populations. The decline in growth of the species is not limited to the one area but it is rather rangewide. Besides the problem of declining in growth, the poor regeneration of the species was found to be an even more serious problem for the long term survival of the species. This research was conducted to investigate the environmental characteristics and the structure and growth of A. koreana natural stands, to investigate the genetic structure of the species and to develope a technique for restoring the damaged A. koreana stands.
Genetic structure in DNA level revealed that the 18.45% of the total genetic variation was found among populations indicating a significant differentiation among populations. The Mt. Halla population found to be genetically very different from other inland populations. This means that it is important to use the right source of plant materials with plenty of genetic variation when restore the damaged stands of the species. It was found that a serious decline in growth of the A. koreana trees occurred in the year of drought or following the drought year. The various species of mycorrhizae were found in the stands of Mt. Jiri and Mt. Halla, but no common species were found in both area.
