This study aims to understand the their characteristics and analyze the diverse landscape plants distributed in the traditional temples. We surveyed the landscape plants that the planting species around building and terraced flower bed, excluded the spontaneous species. The contents of analysis were form, leaf fall and type, exotic species and the Buddhist symbol plant. Mostly, the families of landscape plants that rosaceae, compositae and liliaceae were much used. The rosaceae were used in landscape planting, and compositae and liliaceae were used in terraced flower bed and flower garden. Especially, a single planting, a linear planting and symmetrical planting most occupied in the planting types. This reason seemed the object and function of religion. There were lots of trees and shrubs in the form, and they were main material for formation of landscape and frame. Therefore, the temple landscape was composed of landscape plants and planting types and fell into chime with these components. The deciduous broad leaved was many in the leaf fall and type. The aesthetic value is a deciduous broad leaved directed by the external features of nutrition and reproductive organs with plants and flowers, recording, leaves, fruits, and non-seasonal forms along with the variety of landscapes inspectors by providing visual variety, because expression. Exotic species were introduced intentionally, unintentionally for a variety of purposes in a foreign species, naturalized plants invasive species was the wild country to adapt to the environment. Exotic materials will have to be rejected unconditionally, but indiscriminate use of space in a traditional review of the planting material is necessary because of the high potential to inhibit and distort the traditional landscape. Buddhist symbol plant is a very important feature as plants that have the least Buddhist doctrine and has a meaning and a symbol representing the Buddhist, the inspectors can show the difference with other scenic areas.

The purpose of this study is to analyze the overall condition of the foundation for the three storied stone pagoda of Bulguksa temple in GyeongJu. As a research method, exploration of the electrical resistivity, refraction seismic, surface wave exploration, GPR exploration, Reputation loading test. The results of the investigation, the range of the foundation was formed in foundation stone outskirts of 1.5 ∼ 2.0m. It was confirmed to be about 2.0m depth. The depth of the foundation becomes shallower from the base portion to the outside. And the bearing capacity of foundation was sufficient conditions to weight. It can sufficiently support the weight of pagoda. And, the result of this investigation becomes basis data for repair work.

The purpose of this study is to analyze the cause of damage to the three storied stone pagoda of Bulguksa temple in GyeongJu. This report is attempted to making reinforcement and conservation plan through investigating and analyzing the cause of damage to that. The damage is caused by occurring of stress, degrading of stone strength, changing of underground soil structure, natural disasters and so on. Compressive stress, shear stress, bending stress and lateral pressure affected to the pagoda since built up. Ultrasonic examination data tells the strength of the stone. According to this result, strength of the stereobate stone materials is enough to support the weight of the upper ones. But we could found many other factors of the damage could consider, for example the problems occurred on building the pagoda construction and the weakness of the stone material(soft rock). And many environmental factors being changed in soil structure(subsidence of soil and degradation of bearing power of soil and freezing and melting of soil) can be seen as the cause of the damage. Natural disasters like earthquake, lightning and heavy rain were also thought to give direct impact to the damage. At last Concentration of compressive stress caused the crack and exfoliation on the stone materials and shear stress, bending stress and lateral pressure were main causes of the stereobate stone materials shearing.

경주국립공원 불국사 주변 사찰림을 중심으로 식생구조를 파악하기 위하여 42개의 조사구(단위면적 100m2)를 설치하여 식생조사를 실시하였다. Classification 분석 중 TWINSPAN 기법을 이용하여 군락분리를 시도한 결과, 군락 I은 소나무-잣나무군락, 군락 II는 소나무군락, 군락 III은 소나무-단풍나무군락, 군락 IV는 단풍나무-소나무군락으로 최종 분리되었다. 식생구조 분석결과 경주국립공원 불국사 주변 사찰림은 소나무가 우점하고 있었다. 군락 IV는 소나무 군락에 단풍나무가 유입되면서 단풍나무-소나무군락으로 군락이 변한 것으로 파악되었다. 그러나 최근 자연발생적으로 아교목층과 관목층에 굴참나무, 갈참나무, 졸참나무, 신갈나무가 확산되고 있어 추후 소나무와의 경쟁이 예상된다. 본 조사지역의 산림식생의 임령은 소나무가 우점종인 산림은 30~100년 내외인 것으로 밝혀졌으며, 단풍나무는 30~36년의 수령을 가진 것으로 나타났다.

In the book of <Ancient and New Creation of Bulguksa Temple>, it is recorded that the names of ingressive stone stairs to the main shrine were Cheongwoongyo(blue cloud bridge) and Baekwoongyo(white cloud bridge) and the names of stairs to the paradise hall were Yeonwhagyo(lotus bridge) and Chilbogyo(seven treasure bridge). But, the ingressive stone stairs to the main shrine and the paradise hall are single consecutive stairs with 2 levels respectively. Because of this, it is rather hard to clearly designate the names to the upper level and the lower level stairs. But, of the stairs to the Paradise hall, the lower stairs have a carving of lotus, and the upper stairs have seven stairs. In this aspect of artifacts, we can safely assume that the upper stairs are Chilbogyo and the lower are Yeonwhagyo. But, for the ingressive stairs to the main shrine, there is no such artificial hint. So, it is difficult to designate the upper and the lower stairs for the two bridges. Especially, it is not clear whether the descriptive order of "lower stairs upper stairs" in the names of Yeonwhagyo and Chilbogyo can be applied to the names of stairs to the main shrine. It is because the general descriptive order is "upper lower" rather than "lower upper." Even though there have been many studies on the Bulguksa temple, the study on the ingressive stone stairs to the main shrine has not made till now. Therefore, the study on the position of Cheongwoongyo and Baekwoongyo stairs can have its validity. In this paper, the positional approach to Cheongwoongyo and Baekwoongyo has been made in following aspects: First, the temple structure of Bulguksa; Second, the five element theory of oriental philosophy and the Book of Changes; Third, the directional consciousness of Buddhism. Through the aspects, the validity of up-down position of Cheongwoongyo and Baekwoongyo has been sought. In this research, it can be concluded that the upper level of ingressive stone stairs to the main shrine of Bulguksa is Cheongwoongyo and the lower level is Baekwoongyo. When considered in the Buddhist directional consciousness, it forms the total structure of "East- Cheongwoongyo·South- Baekwoongyo·West- Yeonwhagyo·North- Chilbogyo."

Bulguk Temple, one of the national temples, sublimated the high formalism and symbolism into lovely art, and thus be called the pinnacle of Korean architecture. Of many characteristic structures of Bulguk Temple, the stone stereobate and stairs have a great importance in that we can read out the purpose of the architect through their relics. Especially, the stone stairs are noteworthy for they structuralize the intentional space division. The objects of this observation are Yeonwhagyo and Chilbogyo bridges at the entrance of Keungnakjeon precinct, and Cheongwoongyo and Baekwoongyo stairs at the entrance of Daewoongjun precinct. All these relics are the structures that divide the precinct areas on the basis of Buddhist theory and have strong symbolic meanings as well. Although the diverse studies have made on the structures, there are many insufficient aspects for the manifestation of the meanings. In this study, I considered the Buddhist dogmatic meanings of the structures in the formalistic view of the Buddhist architecture. The study was proceeded in the way that the establishments of former studies were fully reflected in it. Through the study, I could confirm that the objects of consideration have the double formalistic meanings and they are strongly structuralizing the symbolism.
