  • Background: Landscape metrics have been widely applied to quantifying the relationship between land surface temperature and urban spatial patterns and have received acceptable verification from landscape ecologists but some studies have shown their inaccurate results. The objective of the study is to compare landscape metrics and texture-based measures as alternative indices in measuring urban heterogeneity effects on LST at multiple scales. Results: The statistical results showed that the correlation between urban landscape heterogeneity and LST increased as the spatial extent (scale) of under-study landscapes increased. Overall, landscape metrics showed that the less fragmented, the more complex, larger, and the higher number of patches, the lower LST. The most significant relationship was seen between edge density (ED) and LST (r = - 0.47) at the sub-region scale. Texture measures showed a stronger relationship (R2 = 34.84% on average) with LST than landscape metrics (R2 = 15.33% on average) at all spatial scales, meaning that these measures had a greater ability to describe landscape heterogeneity than the landscape metrics. Conclusion: This study suggests alternative measures for overcoming landscape metrics shortcomings in estimating the effects of landscape heterogeneity on LST variations and gives land managers and urban planners new insights into urban design.

  • 근래에 들어 자연환경의 복원은 우리나라의 하천 관리에서 중요한 계획과제의 하나이다. 계획과정에 있어서 경관의 분석과 평가는 보전 지역 및 개발 지역의 적지선정을 위하여 매우 중요한 단계이다. 이 연구의 목적은 생태경관 단위에 있어서 생태환경분야별 조사 특성을 반영할 수 있는 위계적 방법론의 수립과 이에 기초한 적지분석을 통해서 하천내 보전 지역을 설정하는 데 있다. 경관 평가 과정에서 경관 스케일은 광역스케일, 지역스케일, 국지스케일로 구분하여 적용할 필요가 있으며, 이에 따라 환경자료들이 수집, 분석, 종합된다. 이러한 3단계의 단위개념이 도입되어야 하는 것은 하천코리도에서 보전지 설정을 위해 생태 자료들의 다원적 성격을 평가하기 위한 것이다. 위계적 스케일에 따른 평가과정은 3단계로 구분되어 수행되었다. 첫 번째는 장거리 경관 단위로서 광역적 개념에서 하천폭을 기준으로 설정되었다. 두 번째는 각각의 장거리 경관 단위의 지역적 개념에서 경관의 동질성을 기준으로 2이상의 단위공간으로 구분되었다. 세 번째는 국지적 개념에서 교각, 다리, 보의 위치에 따라 세분적으로 분류되었다. 이 마지막으로 분류된 국지적 단위를 기준으로 하여 생태환경에 대한 자료를 재취합, 분석하기 위한 개념적 적지분석모형의 항목들을 선정하였다. 최종 결과에서는 하천 내 습지생태학습공간으로서 집중적으로 관리되어야 할 잠재력이 있는 장소로서 3개소의 보전 지역이 설정되었다. 적지분석과정이 내포하고 있는 많은 가정에도 불구하고, 이러한 방법론적 제안은 우리나라의 하천복원계획에서 다원화된 전문가들과의 공통적 토론을 통해 생태 정보들을 통합하여 실천적으로 적용할 수 있는 틀을 제공할 수 있으리라고 기대한다.

  • This study seeks to find an approach tool that allows to consider both ecological and visual aspect in developing an ecological space. Main objective of this study is to develop a planting design method in consideration of correlation between high visual preference and ecological diversity. To this end, an integrated method based on visual design principles and landscape ecological principles was developed first. Then study areas of 20 natural areas and 10 urban areas were selected to survey and analyze visual preference and ecological diversity. The result showed that scale is an element that has the greatest impact on visual preference. In areas with high ecological diversity, scale and connectivity had the biggest impact. In order to have a planting design desirable visually and ecologically based on these factors, it may be divided into following three issues.(1) In oder to increase ecological diversity in areas with strong visual preference, a priority should be given to introduce techniques promoting harmony among dominant species of various scales and other species. At the same time, there should be efforts to secure connectivity. (2) To improve visual preferences in areas with high ecological diversity, close-range, medium-range, and distant landscapes should be ensured by aligning colors and connectivity of various scales with other factors. (3) Also, a target area should be developed into a visually preferred and ecologically sound area by supplementing form and interlocking issues and identifying the spirit of the place. This study offers a way to improve visual preference and promote ecological diversity indeveloping ecological parks for the future. In landscape planning and design, it is important to secure various scales and connectivity as high-priority principles.

  • Land suitability method has become a standard part of planning analysis at many scales. GIS computer packages have been developed for this purpose. But those are still expensive and hard to learn, and also have limits to extend the results to a landscape design. For the relatively simple tasks and CAD-related works, an application of CAD software for the suitability analysis is very useful and easy to handle. For the purpose, this study develops a technique for suitability analysis, using vector based microcomputer CAD softwares.

  • In this study, the value of reservoir landscape improvement among agricultural infrastructures was analyzed using the CVM(contingent valuation method). The results can be summarized as follows. First, in the decision to pay for all types of large, medium and small scales, the probability of acceptance decreased as the price range increased, and the probability of acceptance increased as the interest in landscape increased. Second, the WTP(willingness to pay) to improve landscape derived from logistic estimation was 29,284 won per year for large reservoirs, 20,736 won per year for medium reservoirs, and 16,682 won per year for small reservoirs. Third, conservative estimates using the economically active population to estimate the overall value of the reservoir landscape improvement show that large reservoirs were 955 billion won per year, medium reservoirs were 600 billion won per year, and small reservoirs were 468 billion won per year.

  • The aim of this paper was to investigate images of neighborhood parks and pergola facilities. 280 individuals responded to the 19 semantic differential pollar terms for all four parks. A 7-point semantic differential scale was used. Results from the data analysis suggest several important findings; 1. Mean scores were significantly different in most of S.D.scales according to park and pergola facilities types. As compared with park, S.D.scales values of pergola varied with its visual identity in the spatial composition of park. 2. Data from the factor analysis revealed that four dimensions appeared for all park and pergola types : "Evaluation ", "Potentiality", "Variety", and "Familiarity". 3. In terms of the "Familiarity" dimension, Omok park and its pergola were viewed a ssignificantly more familiar than any of the other three areas. 4. Parks were perceived more positive than pergolas images in the dimensions of "Evaluation ", "Variety", and "Familiarity". 5. Regression analysis showed that "Evaluation "and "Variety" dimensions were mainly related to visual preference.

  • 지명학과 풍수지리학에 나타난 공간인식의 규모를 찾아내기 위해 지명에서 한자의 뜻과 부합 되는 자연부락의 외곽을 가지는 면적에 대하여 현상학적으로 위요감을 느낄 수 있는 공간규모의 기준을 도출하고자 한다. 지명어의 한역화(漢譯化) 구조에서 지명의 후부요소를 유형별로 지명에 대응하는 한자어 지명을 살펴보면 대체로 -谷系(곡계), -村系(촌계), -山系(산계), -嶺系(영계), -水系(수계), -野系(야계) 등으로 나누는 것이 일반적이다. 이 중에서 한자의 음(音)과 훈(訓)을 적용시켜보면 -곡계(谷系)의 지명들이 지형적 위요감을 가질 것으로 가상이 된다. -곡계(谷系) 지명에 속하는 후부요소로 가장 많이 나타나는 고유어의 형태는 -실과 -골이며 골짜기 혹은 마을의 뜻으로 나타난다. 본 연구는 지명이 지형의 의미를 포함한다는 점을 지명유래에서 착안하였으며, 지명학을 근간으로 전라북도 진안군 270개 자연부락 중 -곡(谷)계 지명에 속하는 33개 부락을 대상으로 조사 분석한 결과 -곡(谷)계 지명을 가진 자연부락은 대부분 사신사(四神砂) 풍수이론이 근간이 되어 대부분 어떤 형태로든 위요(圍繞)되어 있었으며, 그 공간규모는 10만~25만$m^2$이다. 이러한 규모의 공간을 우리 조상들은 부락을 형성할 때 아늑한 공간으로 인식하였음을 분석결과 확인하였다. 공간규모를 시각적으로 쉽게 비교하기 위해 방과 같은 정방형으로 환산하였을 때 한 변의 길이는 300m~500m의 규모를 보이며, 이는 방과 같은 아담한 외부공간으로 인식하였을 것으로 판단된다.

  • This study was conducted to identify the differences in physiological and psychological effects between artificial and natural plants. Artificial and natural plant pots consisting of the same species and forms were prepared, and 40 subjects were asked to look at these plants for 3 min, and psychological responses were measured. Semantic differential, profile of mood states, and positive and negative affect schedule were used as psychological response measurement scales. As a result, regardless of the difference in plant material, as plants were viewed, negative emotions decreased in psychological terms. This result suggests that artificial plants can replace natural plants and that the use of artificial plants can be improved if planting natural plants is difficult because there is no difference in the psychological effects provided by artificial and natural plants.
