The function of urban parks as wildlife habitats is becoming increasingly important. The urban park serves as a key area for preserving urban biodiversity. The purpose of this study is to estimate the bird species diversity in 30 parks in Cheonan city and quantitatively analyze the influence of vegetation, park structure and landscape connectivity index. As the results, a total of 27 birds species and 1,509 individuals were found at the sites and the largest number of birds were found in the Cheongsa park with 17 species. The optimal regression model was selected as the explanatory variables for the logged park area (LPA), the tree cover ratio (Co_T) and the patch betweenness centrality (PB). LPA and Co_T mean the internal characteristics of the park, and PB was the external environmental variable meaning landscape connectivity. LPA was the most important factor (73.3%) as bird habitat, and the PB could be interpreted as a factor that should be considered as important (26.7%). It will be possible to consider these environmental variables in the park and green area construction and management.

하천 수위 유지나 용수 취수 목적으로 사용되는 보는 현재 국내에 약 18,000여개 정도가 설치되어 있으며, 대부분 용수 공급 시설로 이용되고 있다. 하천에 보가 축조되면 하천생태통로의 차단, 보 상류부 수질 악화, 수변 생물서식처의 변화, 경관 훼손 등의 문제가 발생하게 되지만, 이를 해결하기 위한 방법은 극히 일부 보에 생태 통로로서 설치되는 어도 외에는 거의 혀는 실정이다. 최근 농경지 도시화, 경작 방식의 변화, 취수시설물 통폐합, 시설 노후화 등으로 매년 수십 개 이상의 보가 폐기되고 있으나, 폐기된 보는 천거되지 않고 하천에 존치되어 여전히 문제를 발생시키고 있다. 외국의 경우에도 기능을 상실한 보/소형 댐을 보 철거 의사 결정 과정을 통해서 철거를 결정한 후 철거를 시행하고 있으며, 기 철거 사례를 분석한 결과를 바탕으로 과학적이고 공학적인 보 철거 우선 순위 결정 방법을 제시하기 위해서 노력하고 있다. 국내의 경우 아직 보 철거를 통한 환경 복원이 일반화 되어 있지는 않지만, 그 필요성이 점차 증가하고 있으며, 이를 위해 국내 환경에 적합한 보 철거 의사 결정 과정 마련을 위한 연구 필요성이 같이 증가하고 있다. 본 연구는 보 철거를 통한 하천생태통로 복원 기술 개발을 위한 기초 연구의 일환으로 보 기능 저하 요인 파악을 위해 각 주요 수계에 설치된 보를 현장 조사하였다. 조사 결과 기능이 저하 중인 보로 판단되는 보는 분석하여 유형화하고, 요인별로 대표적인 예를 제시하여 이후 판단 자료로 활용할 수 있도록 하였다.

Questionnaire survey from 101 visitors and 77 specialists was carried out to establish the management plan on landscapes of the artificial structure constructed in valley within Bughansan National Park. When comparison was made between ground sill work structure and valley landscape, visitor group responded to the highest scores in valley landscape after planting of vine species in the bottom of the constructure, while specialist group responded to valley landscape after the removal of the constructure. When it made a comparison between revetment work constructure and valley landscape, visitor group responded to highest scores in valley landscape after planting of vine species in the top of the constructure, while specialist group responded to valley landscape after replacing concrete revetment by stone revetment constructure. When it made a comparison between fall work constructure and valley landscape, both groups responded to the highest scores in valley landscape after the removal of the constructure. According to the valley landscape analysis, artificial constructures built in water channel should be matched to adjacent landscape with the removal of concrete constructure. The slope of water channel should be considered to build fall work constructure.

The purpose of this study was to investigate factors and variables which have significant effects on visual preference of urban stream in Taejon city and to suggest design & management information for urban stream. These works consist of two phases. First, we tested the Hyechon college students' visual preference for 36 spots of urban stream slide and then selected 10 spots slide by the Sturges' formula. Second, we analyzed factors and variables of visual preference of urban stream using the semantic differential scale method and then processed using descriptive analysis, factor analysis and multiple linear regression analysis. The major findings of this study can be summarized as follows. 1. The difference of landscape adjectives between the highest score of visual preference slide (No.10) and the lowest score of visual preference slide (No.2) was cleanness. 2. Three factors, the nature, the cleanness and the movement, were derived from the factor analysis. 3. Factors covering the visual preference of urban stream have been found to be the landscape of urban stream, the nature, the cleanness, and the movement. The visual preference factors of urban stream need to be considered in creating or restoring the ecological urban stream landscape.

Numerous developments have damaged agricultural landscapes and consequently agricultural areas have lost the amenity and their traditional culture. Despite the fact that damaged agricultural landscape is irreversible, precautionary policies for conserving agricultural landscapes in Korea have not been established properly. Meanwhile, social demands for well preserved rural landscapes have increased. This study, thus, aims to evaluates esthetic values of agricultural landscapes in order to prepare the basis for the formulation of properly informed policies. Bearing in mind the purpose of the study, firstly, present status of agricultural landscapes has been surveyed. Secondly, agricultural landscape values were estimated in friendliness, ruralness, and preference with 30 selected slides and 4 computer simulated pictures out of 305 pictures. The survey has been carried out with two student's groups of the landscape architecture majored (50 people) and the ordinary majored (68). The results implicated that agricultural landscape preferences has not been changed for 10 years to some extent. However, landscape majored respondents showed low preferences on the artificial creatures than the non-majored. Lastly, Recommendations for the agricultural landscape policy was made that the necessary developments should be considers form, colour, location, and size according to the natural landscape.

In the 1960s, polluted urban streams were covered and paved in concrete. Rivers became sewers buried under road. As a result, wildlife habitat was lost and the open stream space was gone. In the 1990s, there was a movement for restoring urban streams to enhance the quality of life of inhabitants. Chungkye Stream, whose covering began from early 1950s and ended in 1977, is now in the process of restoration together with the Central Business District (CBD) Redevelopment Plan. However, as the construction proceeds, several problems were raised, and serious controversies resulted. Therefore, this study aims to investigate the validity of the approach of the Chungkye Stream Restoration Project through a literature survey and a site survey, and to present the improved alternative. Ultimately, the study aims to contribute to present references or guidelines for similar urban stream restoration projects. The Chungkye Stream Restoration Project has some of the following problems. First, the construction should be done based on the long-term urban redevelopment plan. Second, the construction period should be extended to restore urban streams. Third, the cultural asset conservation plan should be implemented. In order to fulfill the anticipated purpose, the above mentioned problems need to be solved.

These days, one of the issues well discussed is the obstruction or screen of sight to mountain-skyline by buildings. So question is to which heights buildings should be constructed over mountain-skyline and then harmony can be realized between mountain-skyline and building-outline. Based on the mentioned above, this study intends to find out the proper projection- level of buildings over background mountain-skyline when considering the types of mountain-skyline, building-outline and building-layout. The results of this study are first, the proper projection-ratio of buildings over background mountain-skyline can be 0.1 because assessment values on harmony-level are more than 3.0 in almost cases, second, the building-outline influences on the assessment values of harmony-level when the types of mountain-skyline are formed left-high & right-low and right-high & left-low, third, building-layout doesn't influence on the assessment va lues of harmony-level, finally, statistically difference doesn't exist between expert group and non-expert group in the assessment values of harmony-level.
