  • Pinus densiflora stands are common secondary forest communities on infertile soils in Korea. The stands are results of long severe past biotic pressure such as cutting, burning and grazing. These could be regarded as biotic climax in Korea. Because of their prevalent occurrence, relatively simple species and age composition, and their domestic economic importance, study of their distributional patterns may give some basic knowledge for better utilization of land resources in Korea. To detect distributional patterns and interspecific associations ten pine stands, each of which was homogenious with respect to topography and physiognomy, were subjectively selected from pine stands in Kyunggi Province near Seoul in 1969 and were made object of this study. Four contiguous systematic samples of count for trees, shrubs and seedlings from belt transects were collected from homogeneous areas within ten natural pine stands. The belt transect was 64m or 128m in length, and 1m, 2m or 4m in width. Basic units within the transect ranged from 64 to 256. The data from the contiguous transects were analysed in terms of multiple split-plot experiment. Departure from randomness of stem distribution, i.e., pattern, was tested in terms of variance mean ratio. For the detection of association between species, correlation coefficient was calculated for different block sizes. The values of ${\gamma}$ were tested by the usual t-test. Fine trees within one of the stands showed significant regular distribution through out the blocks. Within other eight stands pines were randomly distributed at basic unit with 4$\times$4m, 2$\times$2m, 2$\times$1m and 1$\times$1m. One significantly clumped distribution at basic unit 2$\times$2m, however, was observed from one of the pine stands. These randomly distributed groups were themselves significantly regularly distributed throughout the blocks for four pine stands. For the other four pine stands, in addition to the random distribution at the basie unit(the primary random group), randomly distributed groups with 32m dimension(the secondary random groups) were also observed. Both the primary and the secondary random groups were significantly regularly distributed at the rest of blocks. Pine seedlings were not distributed randomly thoughout the blocks. Within three of the ten stands they were contagiously distributed. Important shrub species underneath pines such as Querus serrata, Q. acutissima, Leapedeza intermedia, Rhododendron Yedoense var. poukhanenae, Juniperus utilis, Rhododendron mucronulatum var. ciliatum shnwed consistently similar distributional pattern with the pine at each stand. The shrub species pairs; Rhododendron Yedoense var. poukhanenae/Quercus serrata, Rhododendron mucronulatum var. ciliatum/Lespedeza intermedia were significantly negatively associated from 1m to 4m dimensional block sizes but became significantly positively associated from 8m sized blocks on. On the other hand the shrub species pairs; Lespedeza intermedia/Robinia Pseudoacacia, and Lespedeza bicolor var, japonica/Lespedeza intermedia were also significnalty negatively associated from 1m to 8m sized blocks but became significantly positively associated from 16m sized blocks on. The associational pattern between Rhododendron mucronul tun var. poukhanenae and Lespedeza intermedia was not consistent throughout the stands. In some stands negative associations were observed throughout the blocks except NS 32. From these observatons micro-edaphic variation within the pine stands seems not to be great enough to cause distributinal difference of pine trees within the ten pine stands. Among each species and pine seedings, however, the edaphic variation within the pine stands may be great enought to cause distributional variation.

  • The diversity of arbuscular mycorrhizal fungi (AM) was investigated in cultivated and natural fold sites or chungbuk, Korea. soils were collected from rhizosphere or Sorghum bicolor, Fagopyrum esculentum and Glycine max in cultivated sites, and of Miscanthus sinensis, Glycine soja and Lespedeza cuneata in natural sites. Total 20 species of Glomalean fungi were found in this study. Species richness, species diversity and density of AM fungi were significantly lower in the arable sites. While only AM fungal spores belong to Glomus and Acaulospora were found in arable fold sites, more diverse fungal spores including Gigasporaceae were found in natural grasslands. AM fungal spore composition did not significantly differ among crop plant species. Results suggest that the agricultural practices were significantly influenced on AM fungal community structures and mycorrhizal developments.

  • 충청북도 일원에서 1976년부터 1981년사이에 산불이 발생한 산화적지와 그에 인접한 비산화지의 식생과 토양성분을 조사하여, 산화 후의 식생회복과 토양성분과의 관계를 분석한 결과는 다음과 같다. 1. 79-B의 우점종 순위가 억새-산거울-싸리의 순으로 비산화지와 같게 나타나 산화 후 2년째 회복되었고, 그 후 산화적지에서 싸리가 점차 우점종으로 발달하여 산화 후 5년이 지난 76-B의 우점종 순위가 싸리-산거울-억새의 순이었다. 2. 생활형 조성은 산화 후 2년째부터 조사지소에 따라 H-e-$D_1-R_5$ 또는 Ph-e-$D_1-R_5$로 산화적지와 비산화지가 같게 되어, 산화 후 2년째에 산화적지의 생활형이 회복되었다. 3. 천이도는 81-B의 DS=423, 81-U의 DS=524로 산화적지가 낮았으나, 산화 후 2년째인 79-B의 DS=510, 79-U의 DS=520으로 거의 같았고, 산화 후 3년째부터는 산화적지가 비산화지보다 점차 높게 나타나 산화적지는 비산화지보다 천이가 빠르게 진행됨을 알 수 있다. 4. Shannon-Wiener function, Morishita's index 및 Simpson's index 등 종 다양성의 분석 결과에 의하면, 산화 당년에는 복잡한 군집이었으나 산화 후 2~3년째에 비산화지와 같은 단순한 군집으로 회복되었다. 또한 Evenness index의 분석 결과, 산화 당년에 식물종수가 비산화지보다 많았으나 산화 후 2년째부터 비산화지와 같은 종수가 되었다. 6. 산화적지의 식생은 산화 후 2~3년째에 비산화지의 식생과 거의 같게 회복되었고, 토양성분도 2~3년째에 회복되었다. 따라서, 산화 후 식생회복 과정과 토양성분의 변화사이에는 밀접한 관련이 있었다.
