Light has been an essential part of human life. The advancement of technology has changed cities' nightscape and night activities in a drastic way. Lighting has influenced the identity of a city while promoting a variety of civic nighttime cultural pursuits, yet lighting design has not been considered adequately in the field of landscape architecture. This study aims to analyze the current status of lighting in urban parks through interviews with professionals, literature and regulation reviews, analysis of design documents and a field survey focused on Yeouido Park in Seoul. The findings and improvement directions are as follows. First, it is necessary to develop a specific lighting design method in order to avoid a marginalized, passive approach such as light fixture installation. Second, the existing standards of illuminance by KS A 3011 regulating only horizontal illuminance has turned out not to evaluate the current nightscape of urban parks properly. Therefore the criteria and guideline for analysis and design for nightscape should be articulated. Third, there are no design or management strategies to consider the changing landscape of urban parks, which is necessary due to the changing characteristics of park ecosystems. Lastly, detailed guidelines for distinguished spaces in urban parks should be studied and suggested.

The purpose of this study is to suggest objective basic data for the national park development through the quantitative analysis of the visual quality included in the physical environment of the Dukyu National Park. For this, spatial images structure of physical elements have been analyzed by factor analysis algorithm and degree of visual quality have been measured mainly by questionnaires. Result of this thesis can be summarized as follows. Factors covering the spatial image of the Dukyu National Park landscape have been found to be the overall synthetic evaluation spatial, appeal, natural quality and physical factors such as the overall the synthetic evaluation, spatial and appear yield high factor scores. Thus, these factors can be considered to represent the site spatial image of Dukyu Korean-National Park. By using the control method for the number of factors, Total variance explained by the factors has been obtained as 45.46% and 45.45%. Principal variables of main factors explained above may be the scaling containing the functional criteria of quantitative approach for landscape management of national park development. According to difference of special image from each place, for these variables that decided the visual quality can be differed, and even the same place due to landscape control point change the visual quality can be affected affirmately or negatively, according to recognized by the landscape control point.

This research is attempted to investigate Dongcheon-rock inscription- to understand symbolic meanings from inscribed texts and to find its construction purpose. For the investigation, 25 target areas were selected for field exploration and literature review regarding Dongcheon were also performed. Several design characteristics of Dongcheon are as follows: First, Dongcheon has four criteria according to creation purpose: residential type(家居地型), hermitage type(隱棲地型), nature excursion type(山水遊覽型), aesthetic scenery type(勝景型), moral training type(修身型) and spiritual discipline type(修道地型). This category shows that Dongcheon is constructed at residential area, shelters, and place for leisure, mortal training and spiritual discipline. Second, Dongcheon is also classified by its location: location on village entrance in a deep forest(深山同口型) and location on near stream(溪流隣接型); location on near stream has also two types(連繫型, 單一領域型): location on an independent territory and location horizontal ground(平地型). Through garden creators' managing their garden in forest, valley and scenic spots, they pursue utopia. Third, naming is a way to create new landscape places. By naming a certain natural landscape as Dongcheon, the landscape is symbolized as utopia, appearing fairyland. Designer's desire and thoughts are saturated in Dongcheon.

It is important to evaluate the environmental effect before performing the project and it should be tried to minimize the negative effects through the project planning based on the evaluation. This study aimed to determine environmental criteria and suggest the procedure for evaluating and scoring the environmental change through water resources projects. In evaluation criteria it was involved in water quality, landscape and ecosystem. And we suggested a valuation indicator and utility functions using MAUT in each criteria determined. In assessment procedure, it is involved in quantitative or qualitative estimation at before and after of project. Meanwhile, we suggested that it is desirable to determine the relative weighting of criteria whenever individual project's assessment performed for considering characteristics of the project. To this end, we verified the applicability of the procedure suggested on case. From this study, it will be used in decision making process of water resource project involved in environmental attributes.

The purpose of this paper is to weigh the possibility of endangered Jang-hang wetland at the estuary of Han River to be included on the Ramsar List of Wetlands of International Importance and come up with ways to manage the wetland depending on its biotope patterns. The target area is located between Gimpo bridge and Isanpo I.C. with about $2.7km^2$ area. Through the analysis of RIS(Information Sheet for Ramsar Wetlands), it was known that the wetland is located on the sedimentary topography and formed as a result of sediment at the estuary of the river owing to the concentration of rainfall during summer. The vegetation environment in the area is divided into brackish water and fresh water areas depending on salinity. Rhizosphere soil(RS) of the area was analyzed to be Silt loam while bottom RS to be Sand loam. The plant ecology was composed of 52 families 135 species and 11 varieties and 146 types. Among indigenous species found are Salix koreensis, Phragmites communis and Miscanthus sacchariflorus. The analyzed results of the actual vegetation showed that willow community accounts for 37% of the area and rice field is 13.5%. As for animal ecology, total of 62 species and 25,977 individual wild birds were observed. After comparing and analyzing the RIS we compiled with the Ramsar Site designation standards, it turns out that the Jang-hang wetland meets criteria 1(biographic region), criteria 2,3 and 4(species and ecological communities) and criteria 5 and 6(water birds). Thus, Jang-hang wetland is eligible for the Ramsar site. As a result of establishing and evaluating the biotope types for setting management areas, Jang-hang wetland has a total of 13 different types, and the grade I represents 75.4% of the area while the grade III 0.8% of the land status. We categorized four management zones for the wetland depending on the biotope patterns - preservation, restoration, use and buffer zones and suggested management methods for each zone.

Gyeong Po in Gangneung is highly recognized as a scenic area that is home to twelve traditional pavilions which are still in existence today. Since the modification of the Natural Park Act in 2007, there has been serious concern about the regulation of the heights of buildings surrounding Gyeong Po. In light of this, the present study aims to provide some guidelines for the regulation of building height in the modified Natural Park Act on the basis of investigations of landscape characteristics of Gyeong Po and the psychological influences of changing building heights. The analysis of the view from the pavilions located around Gyeong Po Lake indicated that the strategic landscape control points were Gyeong Po Dae and Bang Hae pavilions in terms of landscape management. These two landscape control points were considered as points from which people could view the greatest part of the landscape surrounding Gyeong Po Lake. The results of a preference analysis revealed that the views from Gyeong Po Dae to Juk Do were of relatively higher preference than the view from Bang Hae pavilion. This finding emphasized the importance of landscape management in Juk Do and its surroundings. A factor analysis resulted in three factors including attractiveness, tranquility, and orderliness. A comparison of the magnitude of influence of these three factors showed that the order of influence to preference was: attractiveness>tranquility>orderliness. These results highlight the need to introduce landmarks or unique buildings into the areas because the panoramic views of Gyeong Po Lake are relatively flat as lake views go. There should also be a variety of skylines harmonizing with the natural landscapes and landscape management for building groups, rather than individual building control, to enhance tranquility. Analysis of the psychological effects of building height suggests that, regardless of view points, preference was split at a 30 meter building height. This was indicative that viewer preference would drop when building heights are controlled to allow heights over 30 meters. The present study was not able to take varying view points and story heights into account. A more detailed study considering building types, the arrangement of buildings and the number of building stories is needed for effective landscape management in the Gyeong Po Dae area.

Increased investment in environment-friendly transport vehicles has led to rapid transit of railway tracks, double track program, linear improvements in railway lines, and moving railroad routes into the suburbs. They resulted in fast increase of railway yards. However, as the railroad yards being neglected, urban fine sites have been degraded. Local governments kept seeking ways to utilize the railway yards. In addition, Ministry of land, infrastructure and transport enacted "Guidelines for utilization of railway yards". The Guidelines categorized the railway yards into three types; conservation, utilized, and other sites in order to make efficient use of them. The railway yards have been converted and used for parks, rail bike trails, bike paths, and solar projects. It seems that studies are needed on diverse use of the yards and on post evaluation. This study investigated current uses of railway yards, domestic and foreign, and analyzed for the pertinent conditions on natural and cultural landscape, educational value, location and accessibility, potential for recreational area, and development opportunities. In this study, I proposed a quantitative evaluation method, and to find way to diversify the use of railway yards.

Various strategies and management plans have been established in order to conserve water quality as well as ecosystem, prevent deterioration of scenic area, and more importantly, retain drinking water securely. However, due to the introduction of numerous small-scale development projects on the waterside area outside protection area of source water and reparian area, river water quality and landscape are severely deteriorated. In this study, We analyzed the expected environmental impacts on the ecosystem, topograph, geology, landscape, water quality according to development type, and assigned different environmental points to each development type depend on environmental impacts, which is able to divide small-scale development project into three categories such as projects with rigorous review, projects with general review and projects with simple review. Finally, we suggested the appraisal basement is to avoid or minimize the expected environment impacts of the small-scale development projects in riparian areas so that make them sustainable development by reasonable restriction.

The purpose of this study is to derive policy suggestions and new orientations for biotope mapping in Korea from a review of case studies on the classification of biotope typesin Germany. This study was conducted in the following manner: First, the related literature and data on biotopes in Germany was collected. Second, the representative examples at the provincial government level and urban and residential areas were selected. Finally, the characteristics of biotope types, biotope classification systems, and biotope classification criteria were reviewed. The results of reviewing the case examples in Germany are as follows: First, the biotope types at the provincial government level were composed of patterns which existed mostly in natural areas and the corresponding areas of their conditions. Those in urban and residential areas were made up of patterns which were distributed in urban areas and their peripheries. Second, the biotope classification systems at the provincial government level consisted of three steps:large, medium and small. Those in urban and residential areas were made up of two steps: medium and small. However, it is strongly recommended to introduce the biotope classification system composed of three steps. Third, the biotope classification criteria at the provincial government level considered ecological factors and anthropogenic factors except land use forms. Those in urban and residential areas reflected mostly anthropogenic factors and ecological factors. In conclusion, this study suggests that future biotope surveys and mapping in Korea should be investigated not only in urban areas but also in natural and semi-natural areas. In addition, a specified biotope type classification system should be established in Korea.

This study sought to contribute to the revitalization of local economy by developing a natural recreation forest, which is the base of ecotourism recreation, through utilizing forest resources and the natural environment of Gwangju-si. The study conducted a feasibility assessment through on-site surveys such as the suitability of the candidate sites, location analysis, and possibility of damage to the forest, before developing recreation forest sites in Gwangju-si and, based on the result, selected appropriate subject sites. The candidates for this study were 5 forest sites such as one site in the Mokheon-dong area, two in the Docheok-myeon area, and one in the Toechon-myeon area. For this study, the current status of the natural recreation forest was surveyed, its feasibility index and assessment process were investigated, and the local status and related regulations of Gyeonggi-do and Gwangju-si were reviewed. The final subject sites were selected after feasibility assessment utilizing assessment index in order to evaluate the candidate sites. The feasibility assessment was conducted after three separate on-site surveys for each candidate site between October 2018 and January 2019 utilizing "The Feasibility Assessment Criteria for Natural Recreation Forest (Notification 2018-71)" of the Korean Forest Service. The items instrumental to the feasibility assessment were classified into landscape, location, water system, induction of recreation, and development condition; the assessment was made after redefining each item into detailed items. Through this process, the Usan-ri area was selected as the final site for developing natural recreation forest, having obtained more than 100 points according to "The Feasibility Assessment Criteria for Natural Recreation Forest" of the Korean Forest Service. In order to develop natural recreation forest in the Usan-ri area in the future, further discussion is necessary with the relevant departments in consideration of the degree of ecological zoning map.
