본 연구는 명지산 식생의 보전방안의 수립과 생태계의 건전한 이용을 위해 수행되었다. 인위적인 훼손이 지속되는 등산로 주변은 질경이군란과 쑥-미국쑥부쟁이군락 등 노변식물 군락으로 나타났으며, 등산로 주변과 벌목지는 중부지방에서 잡목림이라 할 수 있는 고추나무-산뽕나무군락으로 나타났다. 그러나 중부지방에 위치한 명지산의 기후적 극상림인 낙엽활렵수림의 군락은 표고 300m 이상의 깊은 계곡과 정상부근에 극상림에 가까운 신갈나무-당단풍군락으로 잔존하는 것으로 나타났다. 또한 신갈나무-당단풍군락 주변에는 비교적 인위적인 영향을 크게 받은 병꽃나무-조록싸리 군락으로 구분되었다. 또한 이들 군락 내에서는 금강초롱꽃, 백작약, 도깨비부채, 개족도리 등의 희귀 및 멸종위기 식물들이 다수 관찰되었다.

Amphibian biodiversity, community structure and habitats were surveyed in the Mt. Myungji area from April 2002 to March 2003. During the survey period 2orders, 4 families, 7 species of amphibians were observed. Bombina orientalis (DI =45.1%) was dominant and Bufo stejnegeri (DI = 12.8%), Rana rugosa and Rana dybowskii (DI = 9.9% each) Rana nigromaculata and Rana huanrenensis (DI 1.4% each), and Onycodactylus fisheri (DI = 7.0%) followed. Frequency of occurrence of O. fisheri and B. stejnegeri was largely different according to the altitude and human residence in their habitats.R. nigromaculata and R. huanrenensis showed low frequency of occurrence (<10%) suggesting the decrease in habitation density in this area. The species richness (R'), general diversity (H'), and evenness (E') of amphibians in this area were 0.98, 2.12, and 0.76, respectively, suggesting relatively healthy condition of amphibian community in this area.

This study was conducted to investigate the flora of Mt. Myongji and also to find the distribution characteristecs of rare and endangered plants in this mountain. Field surveys were carride out 21 times from 1991 to 1997. Main results obtained from this study were as follows; 1. Mt. Myougji was covered with Pinus koraiensis and Sarix leptolepis stands at the altitude lower than 600m, and deciduous forests which were consisted of Quercus mongolica, Carpinus sp., Acer sp., Cornus sp., Fracinus sp., etc. occupied at the altitude higher than 600m. Dicentra spectabilis population and Anemone population were remardable, and Adenophora grandiflora and Astilbe chinensis var. davidii with white flowers were found. 2. The vascular plants in Mt. Myoungji were recorded as 677 taxa such as 19 families, 358 genera 576 species 90 varieties 11 forma. Among them. 19 families 31 genera 32 taxa were endemic plants and 27 taxa were naturalized plants. 3. 26 taxa of rare and endangered plants protected by Forestry Administration were found in Mt. Myonfji. Among them, Asarum maculatum. Hanabusaya asiatica, Lilum cernum. Jeffersonia dubia, and Cypripedium japonica populations could be regarded as very important in a biogeraphical aspect. So it is necessary to monitor this area in a long term and to establish the conservation strategies.

The Quercus mongolica forest vegetation of Mt. Myongji was classified into two communities including four subunit communities and one typical subunit community by the Z-M method as follows: Acer pseudo-sieboldianum-Quercus mongolica community group Quercus mongolica - Isodon excisus community Quercus mongolica - Styrax obassia community Quercus mongolica - Lespedeza bicolor subunit coummunity Quercus mongolica - Aconitum longecassidatum subunit community Quercus mongolica - Rhododendrom schlippenbachii subunit community Quercus mongolica - Cornus controversa subunit community Quercus mongolica - Styrax obassia typical subunit community Acer pseudo-sieboldianum - Quercus mongolica community group was distributed over the upper region of the altitude 400m, and the differential species in the community were Carex siderosticata, Sephanandra incisa, Tripterygium regelii, and Fraxinus rhynchophylla. The vegetation patterns for the slope and azimuth showed that the highest importance value for Quercus mongolica forest was observed on the broad subxeric area, and for Carpinus cordata and Acer pseudo-sieboldianum on the wet site, for Acer mono, Styrax obassia, Fraxinus rhynchophylla and Symplocos chinensis for. pilosa on the xeric site. The best habitat condition for Quercus mongolica was found at a subxeric site at the altitude of 700-900m on southern slope and that for Acer pseudo-sieboldianum at the 700-1100m on northern slope.

Present work aims to analyse the spatio-temporal distribution of Korean bamboos. The northern limit of Korean bamboo species occurs at Baekryung Island(124°10'E, 37°55'N), Hoochang(41°22'N) and Myungchon(129°41\`E, 41°10'N). The presence of bamboo fossils in Korea dates back from Tertiary, but widespread use of bamboos can be noticed since 1454. Reconstructed ranges and temporal changes of bamboo, based upon the eight historical records from 15th to 20th centuries, indicates that both climatic and anthropogenic factors were responsible for the changes of distributional range. The spread of bamboos was balanced by its disappearance due to regional development, and the total bamboo area showing little change. Due to the tendency to spread extensively by means of underground stems, bamboos often invade adjacent forests and disturb natural vegetation. Proper management and conservation strategies, therefore, are required for the maintenance of rural landscape.

This study aims to compare and analyze the environment of natural parks and Ulleung island using the plant taxa classified by five degrees based on their distributional ranges. The scores differentially given based on the importance of each degree; taxa belonging to the fifth degree are given to 20 scores each, fourth 10, third 5, second 3.3, and first 2.5, respectively. The total assessed scores were ranked as Mt. Halla, Seorak, Jiri, Deokyu, Is. Ulleung, Mt. Sobaek, Odae, Palgong, Chink, Taebaek, Songni, Juwang, Gaya, Duryun, Gaeryong, Bukhan, Naebyeon, Worak, Naejang, Cheongryang, Naeyeon, Myeongii, Jokye, Mudeung, Wolchul, Geumo, Juheul, Biseul, Hwangmae, Jangan, Seonun, Moak, Seonam, Chilgap, and Gibaek, in order, respectively. It is suggested that the natural environments assessing more than 1,000 of total scores such as Mt. Halla and Mt. Deokyu are regarded as the most excellent ones, and those between 700 to 1,000 of total scores such as Is. Ulleung and Mt. Odae are regarded as relatively excellent ones. Natural parks scored between 500 to 700 such as Mt. Palgong and Mt. Gaya are regarded as good ones and parks scored between 300 to 500 such as Mt. Duryun and Mt. Mudeung are regarded as normal ones. The area assessed less than 300 of total scores such as Mt. Wolchul and Mt. Gibaek are regarded as the most inferior ones. The total scores of the national parks are generally higher than those of the provincial and county parks. In addition, Ulleung island has a total of 882.9 scores. Therefore, according to the IUCN the Ulleung island should be included in the criterion of the preservative model of natural ecosystem, suggested by Ministry of Environment. At the same time, Ulleung island should be included to the superior model of natural scenery resources by its uniqueness of topography, geography and natural environments. Ulleung island is assessed as having relatively excellent natural environments as compared with other national parks, suggesting that the island should be designated as a new national park.
