The Seonjeong royal tomb is one of many historic sites in and around Seoul city and its natural environment and landscape have born damaged seriously by heavy use. So conservation planning with an estimation of reasonable carrying capacity shall be required In aspect of not only historic site conservation, but also urban forest and nature park management. Eight sites were sampled with clumped sampling method during July of 1986 and five quadrats were examined in each site. Environmental factors, actual vegetation, and environmental impact grade were investigated in field and vegetational structure was analyzed by estimation of importance value, species diversity, similarity index, DBH class distribution, etc. The result of this study can be summarized as follows. 1. Damage on soil and vegetation of middle and lower layer increased according to amount of users'impact. 2. Semi - natural vegetation covered 63% of the total area(22.2 ha) and its major species were Pinus densiflora, Quercus aliena, Q mongolica, Sorbus alnifolia, etc. Pinus densiflora was a dominant species in heavy impact area. 3. Environmental impact grade 3, 4 and 5 area covered 51% of the seminatural vegetation, Especially, the area of impact grade 4 and 5 should be restored because self-refair seemed to be impossible. 4. The semi-natural vegetation was classified with four plant communities; two P.densiflora comm., Q. mongolica-P. densiflora comm. and Q. aliena comm. One of the P. densifolra comm. was destroyed seriously with no younger trees in middle and lower layer by overuse impact and would be bareland soon. But Q. aliena comm.in light impact area showed just completion of plant succession from P. densiflora comm.

This study was investigated about decomposition process of litter that is reduction pathway of phosphorus from plant body to soil That is, in each community of Miscanthus sinensis, SaSa palmalta. Artemisia princeps and Polygonum thunbergii, disappearing speed was calculated from total fallen leaves yield supplied as litter and litter existant yield. Besides, setting up litter bag that put litter in nylon mesh bag. calculated disappearing speed from decreasing speed of the weight of contents and then was compared and examined. The results obtained are summarized as follows : 1. Maximum litter yield was sequently Miscanthus sinensis＞SaSa palmalta＞Artemisia princeps＞Polygonum thunbergii, but, supplied litter yield was sequently Artemisia princeps＞Miscanthus sinenis＞Polygonum thunbergii＞SaSa palmalta. 2. Reduction speed of phosphorus from plant body to soil was Polygonum thunbergii＞Artemisia princeps＞Miscanthus sinensis＞SaSa palmalta. 3. Caculated disappearing speed using litter bag method was shown latter tendency than that of natural condition. 4. It was significantly negative relationship between N contents of litter and disappearing speed of litter.

The correlation between disturbance intensity and stand development was evaluated on the basis of natural forest community type classification in areas of Baekhaksan (more disturbed area) and Hwangaksan (less disturbed area). The vegetation data were collected by point-centered quarter sampling method, and they were subjected to cluster analysis for classifying community types and to analysis of species composition and species diversity for reviewing ecological characteristics. By the method of cluster analysis, natural forests of Baekhaksan were classified into Quercus forest community, Pinus densiflora community, Q. variabilis community, and Q. mongolica community. Those of Hwangaksan were divided into P. densiflora community, Q. mongolica community, Q. forest community, and Mixed mesophytic community. It is presumed that more developed and less disturbed forest area shows multiple species community pattern and more diversified structure than less developed and more disturbed forest area. In Korean peninsula, the abundance of red pine may play an important indicator to estimate the developmental pattern of the forest after artificial disturbance. The overall evaluation indicated that less disturbed Hwangaksan area had more developed stand pattern with mixed mesophytic community, more complicated species composition, and higher species diversity than Baekhaksan area.

In modern society, the succession and development of tradition can be an enabler of the state in the flow of culture, and the process of modernizing traditional costumes is meaningful work. Neckties are essential in modern Korean men's wear, and they are an important part of men's ornamentation. Accordingly, this study aims to present a necktie design that applies the traditional men's ornaments such as the Ip, Ipyoung and Manggeonsik. The research method is based on a literature review and presents four Korean necktie designs via Adobe Illustrations. As a result of analyzing the beauty of the traditional Korean men's ornamentation, it was categorized into rhythmical beauty, emphasis beauty, and natural beauty. Applying this to necktie design, Design 1 imagined the silhouette of a man wearing a Got and Durumagi. This applied emphasis beauty. Design 2 applied the shaking images of Got and Got-kkeun to apply rhythmical and emphasis beauty. Design 3 applied a man's upper body silhouette and the shape of wearing a Got. This was to apply natural beauty and emphasis beauty. Design 4 applied the shape of Got-kkeun and Gwanja to rhythmical beauty and natural beauty. The significance of this study is that the development of necktie designs using formative Korean elements can be a part of efforts to recognize the possibility of traditional Korean culture and to explore developmental directions under the current situation in which Western clothing is accepted without thought. It is a good idea to suggest the possibility of the modern use of Korean men's ornaments.

Having employed the transitional probability model based on Markov chain, the study was carried out to examine successional trends for community types in the natural deciduous forest of Mt. Jumbong. The species composition of oncoming generation in overstory was estimated from that of mid-story, and the species composition in mid-story was based upon that of understory. Successional trend for each community was predicted from the reorganized probability matrix of tree replacement by the square of climax index, which was evaluated by the factors of light absorption, reproduction, and wood quality. As the result of analysis, following table shows the oncoming generation of steady state and dominant species in overstory and mid-story by community types. Even though Acer pseudo-sieboldianum and Carpinus cordata could hardly reach the canopy layer due to the intrinsic growth form, these species were predicted to maintain high compositional ratio so as to play an important ecological role in the study forest ecosystem.

The focus of this study is the promotion of green area volumes and their naturalness, water circulation system, decline of entropy, creation of biological habitats and linkage of separated urban green space. Re-presentative urban biotope survey sites were categorized as urban biotope, semi-natural biotope, and natural forest. In the urban biotope, a residential biotope was constructed near the Han river and in mountain areas. The green-area ratio at the housing complex was about 25%. GVZ(Grunvolumenzahl) was 0.35m$^3$/m$^2$ at the 5∼10-story housing complex, and 1.53m$^3$/m$^2$ over the 11-story. As for the green-area structure of the housing complex, canopy layer, understory layer, and shrub layer were not differentiated and the green-area volume was not high enough. The green-area ratio of school areas as a public area biotope was 5∼20%. GVZ was 1.12m$^3$/m$^2$ at Myungduk High School, and 1.78m$^3$/m$^2$ at Jeonggok Elementary School. In order to convert the urban biotope into an ecological area, green areas around the buildings should be connected to urban buffer green areas, and multi-layer structures should be established with natural plant species. In the semi-natural biotope, neighbor parks were created park in the vicinity of the natural forests. GVZ was 0.28m$^3$/m$^2$, and plantation was established with single layer structure and was definitely insufficient for the area. The urban buffer green areas have been established in strip corridors with the width of 20∼123m. In those areas, GVZ was 0.16∼0.27m$^3$/m$^2$ and had a deficient canopy layer, understory layer, and shrub layer. Soil conditions were not favorable for tree growth. In the natural biotope, GVZ of the plantation was 1.03∼1.5m$^3$/m$^2$ but the high crown closure of this area reduces the chance of species change and succession. GVZ of natural forest was 2.53∼2.57m$^3$/m$^2$. It is desirable to plant diverse plants and the natural forest should be succeeded by broad-leaf deciduous tree species. To improve the value of biotope at Kangseo-Gu, building height needs to be limited to reduce the environmental deterioration in the city. In order to maintain the water circulation system, water-permeable material is recommened when the urban surface areas are paved. The establishment of a water circulation system will improve ground water levels, soil moisture, water quality, and habitats. In order to improve biological diversity, it is desirable to have multi-layer structures in urban green areas with native species.

This study aims at providing exercisable basic data for the management of protection areas in China by investigating into their legal system such as current laws, regulations, other relevant laws and international treaties and the management system such as history, classification, organization, personnel, funds and main management work.. In People's Republic of China (1954), several laws have been enacted in succession, such as Environment Law (1989), Regulations of Natural Reserves (1994) and Land Management Methods of Natural Reserves (1995). The development process of China's natural reserves is divided into the following five phases. In the initial phase (1956-1965), about 20 natural reserves were established; in the lag phase (1966-1978), a part of the natural reserves was destroyed under the influence of the Great Cultural Revolution; in the development phase (1979-1998), a normative legal system began to appear after the reform and opening up; in the leap phase (1999-2006), the number of natural reserves increased dramatically; in the stable phase ( 2007-present), the protection and restoration of the ecological environment have been implemented, and the supervision and management have been strengthened. China has established natural reserves of national, provincial, municipal and county levels according to the relevant laws. According to the resource categories, natural reserves can be divided into natural ecosystem reserves, wildlife reserves and natural relic reserves. The Ministry of Forestry is in charge of 1,958 natural reserves which account for 74.2 % of the total natural reserves in China. In China, there are 1,384 natural reserves (52.4 %) for which management institutions have been set up. 1,702 natural reserves (64.47 %) are equipped with management staff, showing a higher ratio than the natural reserves which have set up management institutions.

In succession of the previous works, seismo-acoustic analysis was conducted to collect ground truth events and to discriminate surface explosions from natural earthquakes in the Korean Peninsula for 2004. In this period, total 510 seismo-acoustic events corresponding to 10.8 percent of total seismic events occurred in and near the Korean Peninsula were analyzed and discriminated as artificial surface explosions. Events distribution of the seismo-acoustic events in 2004 is similar to the previous results of 1999-2003. And newly determined seismo-acoustic events were added to the surface explosions database. To extend infrasound detection capability, Korea Institute of Geoscience and Mineral Resources (KIGAM) and Southern Methodist University (SMU) installed new seismo-acoustic array (BRDAR) in Baekryoung Island last November, 2004. The array configuration and design is nearly same to previous seismo-acoustic arrays CHNAR, KSGAR, a triangular 1 km aperture. BRDAR consists of 5 short period vertical seismometers (GS-13) in seismic vaults and 13 microbarometers (Chaparral Model 2). Preliminary analysis using data collected from BRDAR shows an extension of infrasound detection capability to western part of the Korean Peninsula. Also, multiple observations of infrasound at BRDAR and other arrays gave an opportunity to localize sound source regions.

This report is a series of the investigation of the secondary vegetation and succession at the forest fire area in Dangji-Dong of Kyungsang-pookdo province. The forest fires occurred on April 8, 1982. This investigation was carried out from June 18, 1982 to May 29, 1983 once in each season. Before to fires, the Pinus densiflora was dominant and the woody plants of understory were mainly composed of the Quercus serrata, Q. dentata, Lespedeza maritima and L. macimowiczii. Compared with the florstic composition between the unburned and burned areas after the fires, the floristic composition of unburned area comprises: 79 families, 194 genera, 223 species, 26 varieties and 6 formae (255 kinds of vascular plants). The index of similary shows 0.77 (S$\Phi$renson:1948) in this area. The analyses of the life-form compositions in the unburned and burned area show 32.9% and 29.3% in dormancy form (H), 42.4% and 37.7% in disseminule form($D_1$), 80.8% and 82.2% in radicoid form ($R_5$), and 57.7% and 61.8% in erect form(e) respectively. The biological type shows H-$D_1$-R5-e, which is common in both areas, and erect form is generally prevailing in these communities.
