1. The plant communities on Mt. Sulak, a typical alpine mountain in central Korea was researched from the standpoint of ecological survey. 2. The plant on this mountain can largely be classified into 2 categories, the warm zone (below 1100m) and the frigid zone. The former is again classified into a broad-leaved tree formation and a needle-leved tree formation, and the latter is calssified into a broad-leaved tree formation and needle-leaved tree formation, and shrub formation. 3. The broad-leaved tree formation in the warm zone can largely be classified into a Carpinus laxiflora-syringa Palibiniana var. kanibayashi association(1), a Carpinus erosa-Acer Pseudo-sieboldianun association(2), and a Quercus mongolica- Tripterygium Regelii association(3). 4. The needle-leaved tree formation in the warm zone can also largely ben classified into a Pinus densiflora- Miscanthus sinensis association(4), Abies holophylla- Tripterygium regelii association(5), Pinus kordiensis- Rhododendron schlippenbachii association(6) In the association(4), the canopy of the Pinus densiflora is gradually being occupied by the Quercus mongolica which is one kind of broad-leaved trees. 5. We can fully see a DryoPteris type of the flour layer plant type in the association (3) and also see a Sasamorpha type in the association (5). 6. The broad-leaved tree formation in the frigid zone can largely be classified into Quercus mongolica- Rhododendron schlippenbachii association (8). The constituents of tree and subtree layers in (7) and (8) associations are similar to those association (3), but the constituents of the shrub layer are different from those of associtation (3) due to the difference in height. 7. The needle-leaved formation in the frigid zone can largely be classified into Thuja koraiensisRodgersia podophylla var. viritis association (9) and Abies nephrolepis-Acer tschonoskii var. rubripes asscciation (10). The species of alpine plants or subalpine plants are gradually increased in this formation. 8. The shrub formation can also largely be classified into a Rhododendron mucronulatum- Patrinia saniculaefolia association (11) and Pinus pumila associatio (12). Association (12) has largely developed on the windy place. Association (12) was burned due to the bombing during the Korean war, but now we recoginized there occurred an invasion of Tripterygium Regelii in such a place. 9. The herb layer species which constitute the shrub formation are mostly alpine or subalpine plants of small size, and their kinds are also very few. 10. The growth of the Moss layer is especially good because of the varied conditions of the habitat. The kinds which can easily be seen are the genus of Thunidium, Haplocladium, Brachythecium, Macromitrium, Holonitrium, Atrichum, Schwstchkeopsis, Grimmia, Hedwigia, Rhynchostegium and Mnium. 11. The genus of the Sphagnum densly grows like a mat at the acid and moisturous place above 1100m. The authors should express their thanks to father. Yang Kisup, Dean of Catholic Medical College, Prof. Yoon Doksuen, from their valuable advice. Thanks arealso due to Prof. Numata, Chiba University, Prof. Takagi, Nagoya University and Prof. Ando, Hiroshima University in Japan for his kind help and identification of Bryophytes.

본 연구는 한국 온대중부지역 소나무림 군락식재 모델을 제시하기 위해 충청남도 당진군 일대 소나무림을 대상으로 다양한 경급의 소나무림을 조사하였다. 유령림부터 장령림까지 총 $10{\times}10m(100m^2)$의 방형구 92개소를 설치하고, 출현개체별 규격을 모두 조사하였으며, 개체간 생육거리 분석을 위해 44개 조사구에 대해서는 1/100 scale로 교목층과 아교목층 수목의 위치를 조사하였다. 분석결과, 모든 조사구의 교목층은 양호하게 발달해 있었으나, 아교목층의 흉고단면적이 교목층의 10%에 미치지 못하고 있었으며, 관목층의 경우 일정한 피복율을 보이지 않고 조사구마다 매우 다양하였다. 이에 소나무 군락식재는 교목층과 관목층의 구조로 조성하는 것이 바람직한 것으로 판단되었으며, 관목층의 경우에는 특정 경향이 없어 식재하려는 인접 지역의 소나무림을 별도로 조사하여 적용하는 것이 바람직한 것으로 판단되었다. 군락식재 모델을 위한 소나무 교목층 흉고직경급별 단위면적당 생육개체수 및 단위면적당 생육개체수와 생육수목간 최단거리와의 회귀식은 높은 설명력을 보였다.

수달 서식지의 식생구조를 밝히고, 식생이 수달의 서식지 선택 요인 중의 하나인지를 구명하고자 연구하였다. 강원도 화천군의 북한강 본류와 지류 지천에서 수달흔적 발견지와 미발견지를 조사하였다. 수계의 식생형은 세 유형(단경초지형, 장경초지형, 관목지형)으로 구분되었다. 단경초지는 연수위변동이 큰 파로호와 북한강 상류에 분포하며, 명아자여뀌 (Persicaria nodosa), 하늘지기 (Fimbristylis dichotoma), 좀명아주 (Chenopodium ficifolium) 같은 일년생식물이 매우 우점한다. 관목지는 지촌천의 하류와 파로호 하부의 북한강 본류에 분포하며, 버드나무 (Salix koreensis)가 절대 우점하였다. 장경초지는 지류 하천에서 흔하며 거의 달뿌리풀 (Phragmites japonica) 순군락이다. 세 유형의 식생에서 수달의 흔적은 모두 발견되었으나 수달 미발견지는 모두 장경초지이었으며, 수달 발견지와 미발견지 간에 장경초지 식생의 상관이나 종조성은 유사하였다. 그러므로 수달이 서식지 선택 시 특정한 식생형을 선호한다고 보기는 어렵다. 다만, 수달 흔적이 발견되지 않은 장경초지는 지류의 상류로써 어류풍부도가 낮은 점이 공통적이다. 수달의 서식지 선택에 먹이인 어류의 풍부성이 가장 주요한 요인인 것으로 판단된다. 어류 풍부도가 높고 사람의 영향이 적은 평화의 댐 지역이 화천군의 수달분포에 최적지인 것으로 보인다.

This text was analyzed and investigated the morphological character, production time and germination characteristic of seed that collect in Chungnam, in order to offer the basic informations for slope restoration and revegetation using Indigofera amblyantha of wild shrub. Legume was cylindrical type and length 31.5mm, width 2.5mm, and seed number of per legume was full ripe 5.5, unripe 0.9. Seed was elliptical type and length 2.4mm, width 1.7mm, and weight of 1,000 seeds was 5.9g. Because seed matured within December and next year January, optimum time of seed production was in mid of January. In the treatment $H_2SO_4$ of 15 minutes, seed germination rate was the highest as 91.0%, and seed germination time (days) was the shortest as 6.7 days. Seed germination time by temperature was the shortest from $25^{\circ}C$. Therefore, seed germination of Indigofera amblyantha was very useful in the treatment $H_2SO_4$ of 15 minutes from $25^{\circ}C$ temperature.

To examine the soil reinforcement by the shrub with shallow root systems for slope stability, we developed insitu apparatus for direct shear test and conducted the insitu field tests for Lespedeza cyrtobotrya, a representative revegetation species for artificial hillslopes. The insitu field tests were conducted for two different soil conditions (the rooted soils and non-rooted soils) and we then compared the experimental values with those calculated from the Wu model. The results showed that the soil reinforcement derived from the insitu field tests ranged from 0.01525 to 0.1438 $kgf/cm^2$ while the one calculated from the Wu model ranged from 0.1952 to 0.2696 $kgf/cm^2$. Our finding suggests more field tests are needed to collect the related parameters in the model application thereby predicting the reliable soil reinforcement by the shrub root systems.

Forest disturbance sometime considered as a tool of management as it believed that mid level disturbance constructs better micro-climatic conditions which ultimately boost up the plant diversity. The effect of different levels of disturbance on species composition and regeneration is very important. Present attempt was carried out in a temperate evergreen oak forest which was under various degree of disturbance. The study area is one of the large ranges of oak forest in Garhwal Himalaya and compensating various types of daily needs of local people. On the basis of IVI values Quercus leucotrichophora holds first position in all the disturbance zones whereas Myrica esculenta upgraded it's rank in highly disturbed zone and showed less impacted species by disturbance. Berberis aristata and Eupatorium adenophorum in shrub layer and Anaphalis adnata and Bidens pilosa in herb layer were found as disturbance friendly species because they attained higher rank in highly disturbed zone whereas Caryopteris foetida was found disturbance-sensitive in shrub layer. The banj oak regenerated well under mid disturbance as compared to no and high degree of disturbance and a sharp downfall in the species diversity was recorded with increasing magnitude of disturbance. Density-diameter curves showed a reverse trend of lower density in higher girth classes. The results of the study should be useful for the forest management strategies.

Cicada is a very familiar insect to people but habitat characteristics of them are not well known. To investigate habitat characteristics of cicada nymph, plant species, plant cover, soil hardness, accumulated organic mass, organic content in soil, and root density were investigated at 11 sites in an apartment complex garden in Seoul. Selected sites had different densities of cicada nymph case above the ground. Density of cicada nymph case was positively correlated with accumulated organic mass, organic content in soil, and root density and negatively correlated with soil hardness. Even though shrub coverage was not linearly correlated with the density of cicada nymph case, 80% cover of shrub was necessary for the high density of them. Data in this study suggested that organic matter in addition to root density be the primary limitation factor of cicada nymph and high amount of litter-fall decrease soil hardness through the increase of soil organic matter. This study suggests that the density of cicada nymph can be managed through organic content in soil.
