Fifteen major naturally populated habitats around the Mt. Halla, Jeju province for wild Cornus kousa are mostly located on the southeast side of the mountains at 850-1,550m in altitude at sea level and are in half sunney areas. More than 40.0% of the naturally populated area of Cornus kousa are edge of forest areas and 53.3% populate on the steep slope of the mountain in 0-5℃. The direction of the slop for about 40.0% of total populated areas is southeast. In the naturally populated areas, total of 64 taxa dividing into 42 families, 59 genera 56 species and 8 varieties have been shown, mostly Hydrangea petiolaris, Rubus oldhamii, Ilex crenata, Sasa quelpaertensis, Ligustrum obtusifolium. It is suggested that these areas are secondary forest in a typical deciduous forest in Mt. Halla where the second transition had been progressed after forest damage or environmental stress. The index of species diversity of plant groups in these areas is 1.286-4.238 based on the Shannon-Wiener's method.

Secondary phenolic metabolites play an important role in plant defense mechanisms, and increasing evidence indicates that many phenolic compounds are important in human health. To date, few studies have investigated the impact of various medicinal plants on levels of secondary plant metabolites. To address this issue, 82 species of Korean medicinal plants were screened to determine their resveratrol contents. Among 82 medicinal plants, 5 species such as Gardenia jasmonoides, Phlomis umbrosa, Rheum palmatum L., Polygala tenuifolia, Rubus chingii HU contained relatively high concentrations of resveratrol $(179.75{\sim}42.71\;{\mu}g/g)$. But, 40 species including Adenophora triphylla var. japonica HARA were only observed low concentrations or trace of resveratrol, and 20 species including Alpinia officinarum HANCE did not contain a resveratrol.

To compare basic information and to inspect impacts situations between 1987 and 1992, this study was executed in Chongnung valley of Mt. Puk'an. And to provide basic informations through the change of plant species diversity, some methods were applied and analyzed such as the degree of environmental impacts and belt-transect method. The results were summarized as follows; 1. In order to find environmental impacts by visitor, the degree of environmental impacts class that was proposed by Kwon(1991) was implicated. In 4 sites, total area of over impact class 2 is 86,692$m^2$ and area of impacts class 4-6 that is impossible to recover naturally is 36,856$m^2$. Totally, the impacted area was profounded qualitatively and quantitatively against 1987's. 2. In the vegetation change by visitor's impacts, species diversity was rapidly decreased as nearer the campsite and trail. And in the basal area and coverage, lower layer species was sensitively changed. Trampling-resistent species is as following; Robinia pseudoacacia, Lespedeza cyrtobotrya, Staphylea bumalda, Clerdendron trichotomum, Stephanandra incisa, Rubus crataegifolius, Lespedeza maximowiczii, Weigela subsessilis, Rosa multiflora, Zanthoxylum schinifolium, Lindera obtusiloba, Callicarpa japonica, Sorbus alnifolia, Symplocos mongolica and so on. In the results of soil hardness test, that was decreased as far away from campsite and trail. 3. In the 4 sites selected in Chongnung valley of Puk'ansan Natioal Park, management plans was largely divided 4 category, such as trail improvement, facilities setting, ecotone vegetation establishment, and vegetation rehabilitation. And a suggestion was provided to each site.

산사태지(山沙汰地)에서의 자연적인 식생착생(植生着生) 및 식생회복과정(植生回復過程)을 구명(究明)하기 위하여 경기도(京畿道) 용인(龍仁) 화성군지역(華城郡地域)에서 산사태지(山沙汰地) 복구공사시행지(復舊工事施行地)(14개소)와 복구공사시행지(復舊工事施行地)(14개소)를 대상(對象)으로 1993년과 1994년에 식생조사(植生調査) 수행(遂行)하였다. 산사태지(山沙汰地)에서는 총 61종(種)의 식생(植生)이 출현하였으며, 초기식생침엽은 주로 참싸리새, 쑥, 고사리, 망초, 산딸기, 국수나무 등에 의해 이루어지고 있었다. 종다양도(種多樣度)와 균재도(均在度)는 복구공사비시행지(復舊工事非施行地)가 복구공사시행지(復舊工事施行地)에서보다 높았으며, 또한 주변식생과의 유사도지수(類似度指數)에 있어서도 복구공사비시행지(復舊工事非施行地)가 복구공사시행지(復舊工事施行地)에서보다 높게 나타났고, 천이도지수(遷移度指數)에 있어서는 두 처리지에서 비슷한 값을 보였으므로 복구공사시비행지(復舊工事非施行地)에서는 주변식생의 영향을 많이 받는 것으로 판단된다. 따라서 산사태지(山沙汰地)의 식생회복녹화(植生回復綠化)에는 초기착생력(初期着生力)이 크고 적응력(適應力)이 큰 참싸리, 새, 억새, 쑥, 고사리, 산딸기, 망초, 국수나무 등과 같은 자생종(自生種)의 활용(活用)이 도입초종(導入草種)의 이용보다 효과적일 것이다.

To select fruit trees suitable for shaded urban garden with Elaeagnus umbellata var. coreana, Malus domestica 'Alps Otome', Malus domestica 'Fujii', Prunus mume, Prunus persica for. persica, Rubus fructicosus, and Vaccinium corymbosum 'Reka', leaf growth in response to different light was investigated two years after 35% shade treatment. Leaf area of E. umbellata var. coreana, M. domestica 'Alps Otome', P. mume, P. persica for. persica, and V. corymbosum 'Reka' increased in shading. Fresh weight of leaves make inconsistent response to shading in every species but dry weight of E. umbellata var. coreana and P. persica for. persica showed the highest 150% and 148%, increment, respectively. Althought leaf water content of E. umbellata var. coreana decreased in shading, there is no difference in P. persica for. persica. Chlorophyll value of E. umbellata var. coreana and P. persica for. persica that showed higher than any other species is correlated with dark leaf green. Compared to specific leaf weight of E. umbellata var. coreana, P. persica for. persica, and V. corymbosum 'Reka' showed lower than any other species in shading, that of M. domestica 'Fujii', and R. fructicosus increased in reverse. These results indicate that E. umbellata var. coreana and P. persica for. persica that showed high value in several invesetigaton items are suitable for shady urban condition considering leaf growth in response to shading.
