The Aesthetic Evaluation of Coastal Landscape

김남형,강향혜 대한토목학회 2009 KSCE JOURNAL OF CIVIL ENGINEERING Vol.13 No.2

The evaluation of coastal landscape is absolutely necessary when coastal zone is managed or coastal space is newly created. However, research on coastal landscape is rare and no guidelines exist for coastal landscape planning and management. This paper therefore aims to present techniques for evaluating coastal landscape from the visual perception opinions of respondents through questionnaire survey and multivariate analysis. The questionnaire is evaluated by the 5-point scale of Semantic Differential (SD) method. With Principal Component Analysis (PCA), the following four principal components are extracted and named as principal component loadings: harmony, safety, rurality, and spatiality. All beaches are classified into the 4 groups by cluster analysis. By plotting scores of their principal components in a 2-dimensional semantic space, the aesthetic characteristics of coastal landscape are clarified for every beach. To clarify the interaction between the principal component scores and the SD scores of preference items, multiple regression analysis is performed. Therefore, the relationship between principal components and the preference trends of coastal landscape will be ascertained. If citizen’s universal perceptions about favorite coastal landscape are understood and their needs are considered in the design and building up of coastal structure or space, more visitors will experience enjoyment, comfort and convenience.

The purpose of this study is to categorize a landscape adjective list for urban landscape analysis. For this purpose, four methods are used. The first method is to survey the foreign landscape adjective lists such as Feimer's EACL & LACL, VRM suggested vocabulary, and IEA and LI's aesthetic factors, which are commonly used in domestic research. The second method is to analyze vocabulary in Korean linguistic textbook the third is to investigate Korean adjective lists from 36 domestic research. The last is to survey adjectives used to express the urban landscapes. 24 landscapes from BunDdang, GwaCheon, YakSoo and ApGuJeong were presented to 40 subjects, whose responses were collected and categorized. The frequency analysis of the adjectives and landscape factors were processed by SJTOOL, which was programmed for Korean vocabulary analysis. The results of this study can be summarized as follows: Foreign adjective lists were mainly focused on the physical features of landscapes and they also had linguistic problems caused by the translations. Therefore, it is undesirable to use the foreign adjective list directly to analyze Korean urban landscapes. The vocabulary from the linguistic textbook has more variety, but it includes many adjectives irrelevant to the urban landscape. More types of adjectives were used in the researches(890 adjectives/295 types), compared with the result of response survey(1,406 adjectives/270 types). Because some adjectives were partly confusing, it is desirable to categorize the adjectives. The categorized adjectives could therefore be more useful and practical for urban landscape analysis.

This study aimed to identify the landscape perception and landscape characteristics of users by utilizing SNS data generated by their experiences. Therefore, how to recognize the main places and scenery appearing on the island, and what are the characteristics of the main scenery were analyzed using online text data and photo data. Text data are text mining and network structural analysis, while photographic data are landscape identification models and color analysis. As a result of the study, First, as a result of frequency analysis of Bakji․Banwol-do topics, we were able to derive keywords for local landscapes such as 'Purple Bridge', 'Doori Village', and location, behavior, and landscape images by analyzing them simultaneously. Second, the network structure analysis showed that the connection between key and undrawn keywords could be more specifically analyzed, indicating that creating landscapes using colors is affecting regional activation. Third, after analyzing the landscape identification model, it was found that artificial elements would be excluded to create preferred landscapes using the main targets of "Purple Bridge" and "Doori Village", and that it would be effective to set a view point of the sea and sky. Fourth, Bakji․Banwol-do were the first islands to be created under the theme of color, and the colors used in artificial facilities were similar to the surrounding environment, and were harmonized with contrasting lighting and saturation values. This study used online data uploaded directly by visitors in the landscape field to identify users' perceptions and objects of the landscape. Furthermore, the use of both text and photographic data to identify landscape recognition and characteristics is significant in that they can specifically identify which landscape and resources they prefer and perceive. In addition, the use of quantitative big data analysis and qualitative landscape identification models in identifying visitors' perceptions of local landscapes will help them understand the landscape more specifically through discussions based on results. 본 연구는 사용자의 경험에 의해 생성된 SNS 데이터를 활용하여 이용자의 경관 인식과 경관 특성을 파악하고자 하였다. 이에 섬에서 나타나는 주요 장소와 경관은 어떻게 인지하고 있는지, 주요 경관 특성은 무엇인지 온라인상의 텍스트 데이터와 사진 데이터를 활용하여 분석하였다. 텍스트 데이터는 텍스트마이닝과 네트워크 구조분석을 시행하였으며, 사진 데이터는 경관파악모델과 색채분석을 실시하였다. 연구의 결과는 첫째, 박지․반월도 주제어의 빈도분석 결과, 지역 경관 대상 키워드인 ‘퍼플교’, ‘두리마을’과 장소, 행태, 경관 이미지 키워드를 도출할 수 있었으며, 이 중 경관 이미지는 감성분석을 동시해 수행함으로써 긍정의 키워드와 함께 도출하여 경관 대상 및 인식을 파악할 수 있었다. 둘째, 네트워크 구조 분석 결과, 주요 키워드와 도출되지 않은 키워드간의 연결을 보다 구체적으로 분석할 수 있어 색채를 활용한 경관 조성이 지역 활성화에 영향을 미치고 있음을 알 수 있었다. 셋째, 경관파악모델을 활용하여 분석한 결과, 주대상인 ‘퍼플교’, ‘두리마을’을 활용한 선호 경관을 조성하기 위해선 인공요소가 배제되고, 원경으로 대상장인 바다와 하늘이 보이는 조망점을 설정하는 것이 효과적일 것으로 파악되었다. 넷째, 박지․반월도는 색채를 테마로 하여 조성한 최초의 섬으로 인공시설물에 사용된 색채는 주변 환경과 유사한 색채 계열, 상반되는 명도, 채도 값으로 주변 환경과 조화를 이루고 있음을 알 수 있었다. 본 연구는 경관분야에서 방문객이 직접 업로드한 온라인 데이터를 활용하여 이용자의 인식과 경관 대상을 파악하였다. 또한, 텍스트 및 사진 데이터를 모두 활용하여 경관 인식 및 특성을 파악한 것은 어떤 경관과 자원을 선호하고 인지하고 있는지 구체적으로 파악할 수 있다는 점에서 큰 의의가 있다. 또한, 지역의 경관에 대해 방문객의 인식을 파악함에 있어 정량적인 빅데이터 분석 방법과 정성적인 경관파악모델을 활용함은 대규모 이용자의 인식을 파악하고, 결과를 바탕으로 이루어지는 논의를 통해 경관을 보다 구체적으로 이해할 수 있을 것이다.

This study aims to establish sustainable and practically applicable landscape value evaluation standards through landscape index and element analysis to construct a forest landscape map. The standards are essential to ensure the appropriateness of the evaluation criteria by establishing a logical basis for forest landscape selection indicators and setting weights between indicators and elements. To this end, the study attempted to develop scientific and objective forest landscape evaluation indicators by applying qualitative and quantitative research methods, such as interviews and AHP surveys with experts. The spatial analysis map was created using GIS based on the pilot site to verify the selected indicators. The grade map of forest landscape resources was prepared to review the adequacy of the indicators. As a result of this study, the resource value of forest landscapes was classified into three categories: absolute values, which are physical resources; relative values, which are visual resources; and humanistic values, which are non-physical resources. The selected nine indicators for physical values are as follows: slope, crown density, tree age, ecology and nature map, forest function classification map, forest genetic resource protection forest, ecological landscape conservation area, Baekdudaegan protection area, and provincial/county/national parks. For visual value, Relative value based on three-dimensional weight analysis was applied, and five factors were chosen for humanistic value: 100 famous mountains, premium forests, landscape bases, landscape axes, and landscape districts. The forest landscape evaluation grades were divided into three, and a management grade chart was presented. Unlike previous studies, this study set three values and presented a method for creating grading drawings based on the results of a comprehensive analysis. It also presented a research method to increase usability.

최재혁,이시영,윤희재,김대수,김양근 한국경관학회 2024 한국경관학회지 Vol.16 No.1

본 연구는 산림경관의 시각적 가치의 특징인 상대성을 평가하기 위한 분석방법을 개발하고자한다. 이를 위해 정량적 조사방법을 사용하여 과학적이며 객관적인 산림경관의 시각적 평가지표를 제안하고자 대상지를 선정하고 산림경관에 대한 시각적 경관자원을 GIS 데이터를 이용하여입체가중치분석방법을 적용하였다. 시각적 경관자원에 대하여 경관계획상 설정된 조망점에서 가시권분석을 통한 능선분할을 하고, 분할된 능선 구분을 통하여 1등급, 2등급 능선을 선정하여 산림경관의 상대적 가치를 평가하였으며, 세종시, 청주시, 대전시를 대상으로 한 분석결과 도시 인접 산림지역의 상대적 가치가 높게나타났다. GIS 분석결과에 대한 현장조사를 통해 비교 검토함으로써 입체가중치 분석이 조망위치에 따라능선의 구분이 가능한지 검증하였으며 경관녹지축으로서 1, 2차 능선의 위계가 형성되어짐을 확인하였다. 본 연구에서 개발한 입체가중치 분석 방법을 적용한 결과는 기존의 산림경관 평가방법에 비해실제 조망점에서 가시되는 권역에 높은 가치를 부여하고 경관계획에서 정한 조망점들에서 더 많이 조망되는 산림경관의 시각적 가치를 정량적으로 산출 할 수 있는 장점을 가지는 것으로 검증되어 향후 산림경관의 시각적 가치 분석에 새로운 방법으로 적용될 가치가 충분하다고 하겠다. This study aims to develop an analysis method to evaluate relativity, a characteristic of forest landscapes’ visual value. To this end, target sites were selected using a quantitative survey method to propose a visual evaluation index for a scientific and objective forest landscape, and the stereoscopic weighted analysis method was applied to the visual landscape resources of the forest landscape using GIS data. The relative value of forest landscapes was evaluated by dividing ridges through visibility analysis at the viewing points set in the landscape plan and by selecting first- and second-grade ridges through the division of ridges. The relative value of the forest landscape adjacent to the city was high. A field survey of the GIS analysis results verified whether the stereoscopic weighted analysis could calculate the relative valuation of the forest landscape according to the viewing position. The hierarchy of the primary and secondary ridges was formed and confirmed as the landscape green axis. The results of applying the stereoscopic weighted analysis method developed in this study show that compared to the existing forest landscape evaluation method, it has the advantage of giving a high value to the area visible from the actual viewpoints and quantitatively calculating the visual value of the forest landscape that is viewed more from the viewpoints set by the landscape plan.

A Visual landscape planning and management system has been introduced and implemented by each ministry so as to solve the problems of visual landscape destruction due to recognition on the value of natural landscape of beautiful territory and various development projects. At present, this system emphasizes the importance of the visual and perceptual aspect of the landscape however, there is a lack of techniques required for comprehensively predicting, evaluating, and managing it. Furthermore, sustainable landscape management after the completion of development projects has been inadequately carried out, as the focus has been only on consultation in the planning process of the development project in institutional performance. To this end, we presented objective and standardized criteria to predict and judge the effects of development projects on landscapes before project implementation. During the implementation of the development project, the influence of the visual landscape becomes accumulated in the construction progress stage. There is a need to identify the main viewpoints and to examine the continuous changes in the landscape-influencing factors, owing to the remarkable influences on the landscape, such as the change in the topography and the change caused by the artificial structure. During the stage of managing the influence on the visual landscape after the completion of the project, the influence on landscape should be monitored by measuring the change in the continuous landscape-influencing factors and determining the extent to which the actual reduction plan has been implemented. These processes should be performed continuously to maintain the quality of the visual landscape. The change in the landscape caused by the development project is shown to cause relatively greater visual damage than other factors composing the landscape owing to the influence of the artificial factors including the structure or the building. This shows that not only detailed examination of the visual impact before the development project but also continuous management is required during and after the development project. For this purpose, we derived eight landscape-influencing factors including form/shape, line, color, texture, scale/volume, height, skyline, and landscape control point. The proposed considering to be of high utilization in that it has a clear target of the landscape influencing factors.

This study saw developed to build a landscape monitoring methodology by simulation of landscape effect prediction. A Visual landscape planning and management system has been introduced and implemented by each ministry so as to solve the problems of visual landscape destruction due to recognition on the value of natural landscape of beautiful territory and various development projects. At present, this system emphasizes the importance of the visual and perceptual aspect of the landscape however, there is a lack of techniques required for comprehensively predicting, evaluating, and managing it. Furthermore, sustainable landscape management after the completion of development projects has been inadequately carried out, as the focus has been only on consultation in the planning process of the development project in institutional performance. The viewpoint for judging the change in the visual landscape of the development plan and development project should be selected as the effective point where the development project is expected to result in a remarkable landscape change. As for the method of selecting effective viewpoints, the main viewpoints are selected by analyzing the visible area of the target viewpoint. When selecting the viewpoint centered on the viewpoint target, it was judged that it is possible to reduce the procedure of selecting and checking the existing preliminary viewpoints and widening the effective visible range. The proposed visual landscape monitoring is expected to be able to solve the existing institutional problems, and to be used when the implementers and authors of the development projects review the effects on the landscape.

개발사업의 경관영향 검토를 위한 주요 조망점선정 방법에 관한 연구

신지훈,신민지,최원빈 한국조경학회 2018 한국조경학회지 Vol.46 No.1

The Natural Landscape Rating System was introduced in the amendment of the NATURAL ENVIRONMENTCONSERVATION ACT in 2006. For landscape preservation, the system aims to consider the effects of development projectsor plans implemented in a natural landscape on skylines, scenic resources, and view corridors. Currently, a lack of consistencyin standards for determining Landscape Control Points (LCP) to assess landscape impact lowers the accuracy and reliabilityof the assessment results. As the perception of and the impact on a landscape varies, depending on the location of theLCP, it is necessary to establish a reasonable set of criteria to select viewpoints and avoid unreliability in the assessmentdue to unclear criteria. The intent of this study is to propose an objective and reasonable set of criteria for LCP selectionto effectively measure the impact on the landscape from development projects that anticipate a change in the landscapeand, ultimately, to suggest basic analysis methods to assess the landscape impact of development projects and to monitorthe landscape in the future. Among the development projects affecting natural landscapes, as reported in the statementof the environmental impact assessment, cases of construction of a single building or other small-scale development projectswere studied. Four spot development projects were analyzed in depth for their landscape impacts, in order to makerecommendations for the LCP selection procedure, which aims to widen the scope of selection according to the directionof viewpoints from the target site. The existing results of analysis based on LCP have limitations because they failed tocover the viewshed of the target buildings when there are topographical changes in the surroundings. As a solution tothis problem, a new viewshed analysis method has been proposed, with a focus on the development site and target buildings,rather than viewpoints, as used in past analysis. 2006년 자연환경보전법 개정에 따라 자연경관심의 제도가 도입되었다. 자연경관심의제도는 자연경관 내 개발사업및 개발계획 시행 시 사업의 규모와 형태 배치로 인한 스카이라인과 경관보전, 경관자원, 조망축 등의 항목을 검토하는제도이다. 그러나 경관영향평가를 위한 조망점의 선정은 모든 평가마다 기준의 일관성이 미흡하여 영향 평가 결과의정확도와 신뢰도가 크게 저하되고 있는 실정이다. 이처럼 조망점의 위치에 따라 지각되는 경관의 모습이 현저하게 변화하게 되고, 불명확한 선정기준은 경관영향평가 결과에도 시각적 영향이 과소평가되므로 합리적인 선정기준이 필요하다. 본 연구는 개발사업 진행으로 인한 경관 변화가 예상될 때 경관영향을 평가하기 위한 객관적이고 합리적인 조망점 선정기준을 제시하고, 궁극적으로는 개발사업에 대한 경관영향 검토 및 향후 경관 모니터링을 위한 기초적인 분석방법을제시하는데 목적을 갖고 있다. 환경영향평가서의 자연경관 내 시행되는 개발사업 중 단일건축물 및 소규모 개발을 하는사례를 조사하고, 그 중 점적 개발사업 4곳을 대상으로 경관영향평가 부분을 분석하여 주요 조망점 선정과정에 대해제안하였다. 기존 가시지역 분석방법의 결과인 지형 변화에 따라 가시지역 범위를 반영하지 못하는 한계를 극복하기위해 조망 대상물 기준 가시지역 분석방법은 가시 범위를 확대하여 영향력이 높은 유효한 조망점을 선정할 수 있는가능성을 판단하였다.
