  • Phytosociological characteristics on Quercus acutissima forests distribution in Daechong-dam basin survey has been carried out using Z.-M. School's methodology and numerical-classification analyses. A total of 43 phytosociological relevés were sampled. Syntaxa were described as Oplismenus undulatifolius-Quercus acutissima community(typicum subcommunity, Phryma leptostachya var. asiatica subcommunity, Ulmus davidiana var. japonica subcommunity), Quercus acutissima community and Quercus variabilis-Quercus acutissima community (typicum subcommunity, Castanea crenata subcommunity). The above three plant communities were classified with species composition reflecting local environmental characteristics of mountain topographies, inclination degrees, and rock exposure rates. Conclusively, those communities were recognized as secondary vegetation affected by high intensity and frequency of human impacts as they inhabited in southward hill lands and low lying grounds in mountains adjacent to human settlements and arable lands. Quercus acutissima community was classified as rural type syntax based on their inlandward distribution and species composition differences from urban forests. Afforest process and natural succession were discussed in relation with habitat environmental elements of Quercus acutissima forest in the survey area.

  • This study was conducted to compare and analyze forest vegetation distributed in Geumosanseong-inside in Geumosan Provincial Park from 2017.10 to 2019.6. The vegetation structure was classified by the phytosociological method and TWINSPAN and the correlation between the community structure and the environmental factors was analyzed using DCCA ordination analydsis. The vegetation structures are Quercus mongolica, Fraxinus mandshurica, Q. acutissima, Larix leptolepis, Prunus padus and Morus alba community by the phytosociological method and 16 communities under TWINSPAN. The importance value of Q. mongolica(64.5) was the highest, and followed by F. mandshurica, L. leptolepis, Acer pseudosieboldianum, M. alba, P. padus, Q. acutissima, Sorbus alnifolia, P. serrulata var. pubescens, F. sieboldiana, Rhododendron schlippenbachii and Castanea crenata which is consistent with species having the dominance status by analysis of the vegetation structure. As the results of DBH analysis for taxon with high importance values, Q. mongolica and M. alba represented normal distribution, and thus, the dominance status of these species is likely to continue. L. leptolepis will maintain the dominance status due to high density of large individuals as compared with species above medium size. However, it will decrease because of high mortality after increase in age class. F. mandshurica and P. padus continue to show dominance status due to high density of young individuals as compared with species above medium size. Q. acutissima have high density of individuals above intermediate size and low density of young individuals, and thus, will maintain the dominance status. A. pseudosieboldianum, F. sieboldiana and R.schlippenbachii which are arborescent will present continuously high dominance status because of high density of young individuals. Soil analysis shows that whereas pH, Ca2+ and Mg2+ in the research area were lower than the average values of overall forest soil and O.M, T-N, C.E.C and P2O5 were higher. We expected that these results were due to agricultures until 50 years ago in Geumosanseong-inside. As a result of DCCA ordination analysis using eleven environmental factors and communities classified by the phytosociological method analysis showed that Q. mongolica was distributed in the environment with higher elevation and O.M and steep slope, and lower P2O5, Mg2+ and Ca2+. In contrast to F. mandshurica, Q. acutissima was distributed in higher K+ and lower pH. L. leptolepsis was distributed in various environment.

  • 식생자료의 종조성적 온전성(전형성과 대표성) 확보는 Z.-M. 학파의 정제된 식생자료(phytosociological $relev\acute{e}$)와 식물군락(plant community)을 이용하는 국가식생자원에 대한 통합적 관리의 주요 선행 과정이다. 본 연구의 목적은 특정 단위식생으로 모둠화된 식생자료의 종조성 균질성에 대한 질적 양적 평가 도구를 개발하는 것이다. 식생자료의 이질적 요소가 적용된 새로운 균질도, 현존균질도(actual homotoneity: $H_{act}$)와 최적균질도(optimal homotoneity: $H_{opt}$)를 제안하였다. 사례 식생형에서 식물상 변수들, 새로 개발한 균질도, 선행연구의 유사 균질도(Pfeiffer's homogeneity, basic homotoneity-coefficient, corrected homotoneity-coefficient, mean floristic similarity)와의 상관관계는 Spearman 순위 상관계수(Spearman's rank correlation coefficient)로 분석되었다. 현존균질도와 최적균질도는 각각 식생자료 간과 단위식생 간의 식물상 균질성 차이를 더욱 분명하게 드러내었다. 식생자료수로부터 가장 독립적인 균질도는 현존균질도였다. 오랜 교란 역사를 지닌 한반도의 현존식생 조건에서 최적균질도는 현존균질도에 대한 더욱 정교한 해석이 가능한 보완적 수단이 되었다. 현존균질도와 최적균질도는 국가 식생자원에 대한 일관성과 객관성을 포함하는 식생자료의 DB 구축을 위한 균질한 식생자료 선별에 기여할 것으로 기대되었다.

  • The study was aimed to understand the ecological status of the Maebongsan urban forest in Cheongju-si through investigating the vegetation, soil characteristics, and soil microarthropods. Phytosociological analysis for twenty plots revealed that the plant communities were classified into Pinus rigida community, Robinia pseudoacacia community, Castanea crenata community, Quercus acutissima community, Pinus strobus community, Pinus koraiensis community, and Larix kaempferi community. The importance value showed that afforestation tree species like Castanea crenata, Robinia pseudoacacia, and Pinus rigida dominate the urban forest. DBH analysis indicated that although the plant communities seem to be under the succession to Quercus forest, the dominance of Castanea crenata and Robinia pseudoacacia might still persist for several more decades. The properties of soils from the plant communities showed that loamy sand and sandy loam in soil texture, low organic matters, and severe acidification. The abundance of soil microarthropods were not different among the plant communities except Castanea crenata community and Pinus koraiensis community. The two communities showed especially low abundance of collembola and acarina. Thus, we can say that Castanea crenata community and Pinus koraiensis community seem to have been influenced strongly by anthropogenic activities.
