수목원은 자연에서 생육하는 식물의 조사, 수집, 증식 보전을 통해 식물 종을 보전하고 식물 관련연구를 수행하며 식물을 일정한 야외나 실외 공간에 전시하여 국민들에게 식물에 대한 교육과 휴식공간을 제공하는 시설물이라고 정의 하고 있다. 이러한 수목원의 비시장적인 가치를 추정하기 위해 CVM 기법을 이용하여 대구수목원의 경제적 가치를 추정하였다. 가치추정의 방법은 대상재의 설정, 지불수단의 결정, 지불의사 유도 방법 결정, 가상적 상황설정, 설문, 분석, 추정액 도출의 순서로 진행하였으며 대구광역시에서 운영하는 대구수목원의 비시장적인 환경의 가치를 현재의 통화액으로 추정하기 위해 수행 되었다. 가치 추정은 DBDC방식으로 진행 하였으며 분석의 방법은 도출된 추정치가 비교적 안정적으로 알려진 logit분포를 가정한 함수의 분포 형태별로 각각의 추정액을 도출 하였다. 통계적 적합성을 바탕으로 1인당 대구수목원을 방문하여 얻는 연간 휴양의 가치는 WTPmean 12,718원, WTP median 11,033원, WTPtruncated mean 11,468원으로 추정할 수 있었다. 이를 토대로 대구수목원이 제공하는 연간 환경의 가치는 약 160억 원에서 190억 원으로 추정 할 수 있다. 이러한 대구수목원의 환경에 대한 가치추정법은 그 연구 대상지나 대상 재화만 변경하여서 기타의 환경재 가치 추정에도 충분히 적용 가능할 것으로 판단한다.

This research regard it as most meaningful to realize the importance of the hedgerow in cultivated areas functioning as a residual landscape element in rural landscape and set improvement guidelines through landscape character and value analysis to cope with landscape malfunction. The results of summary are as follows. 1) First of all, as a result of landscape character analysis of edge stripe in cultivated land in total of 7 case areas, for example, the edge stripe in cultivated land in case area 4 and 8 maintain the width of 10m and are assessed satisfactory in terms of vegetation development condition, appearance of living species, connectivity, buffer capacity and so on. Also, as a result of structural character of correlation analysis among items, the correlation coefficient between width and appearance of living species showed 0.941, the highest. Following are connectivity and appearance of living species and width and buffer capacity respectively: 0.841 and 0.740. 2) As a result of landscape character analysis of uncultivated stripe in total of 6 case areas, it is analyzed that case area 4 maintains the widest width as almost 4.5m average width and considered valuable as I degree in vegetation development condition, filtering, and connectivity. 3) As a result of problem analysis of uncultivated stripe, for example, case 3, 9, and 10 was analyzed that the width was below 1.25m which is too small to carry out the function of buffer and habitat for living creature, so minimum standard width was set between 4~5m through comprehensive analysis of character of each case area. Based on the result above landscape character, value and problem analysis, main improvement guidelines are set in terms of width, connectivity, filtering, and vegetation development, restrictive practices and so on.

The purpose of this study is to propose the methodology for introducing green infrastructure that can improve the health of citizens by promoting walkability. The methodology is composed of the following three phases: classification of the types of green spaces, selection of core green spaces with two separate analyses, and introduction of the framework of green infrastructure to promote walkability. In the first phase, the classification of the types of green spaces was carried out in order to understand existing distribution pattern of green spaces in study site. In the second phase, walkable blocks were selected by such methods as walkability value. Through these two analyses, all the blocks were divided into three groups according to the ranking figured up the second analyses' results. The blocks in the first group, the group involved in the top 30% and having the greatest ranking, were defined as walkable blocks. In the last phase, a basic frame of the green infrastructure in study site was introduced by connecting the walkable blocks with using other blocks and the green spaces over 1ha. In case study, 28 important green spaces and 35 walkable blocks were selected through the two analysis process. Then, the basic framework of green infrastructure based on the selected 28 important green spaces and 35 walkable blocks was introduced. The methodology applied to this study can be used to get the best selections of the proper green infrastructure in accordance with the purpose of the ecological and recreational local development. In particular, this study will suggest a specific analysis model to use for the ecological and walkable urban planning with green spaces existing in the city.

This is a study on a landscape planning along the street 1~4, which are gateways to Taegu city and an important scenery. Therefore, emphasis was given to provide a bright, clean and beautiful first impression to visitors and citizens. The area is being developed for education and athletic park. Plans to construct a fountain, pergolas and a pond were set up to complement the active and passive facilities to the existing a athletic facilities in the area. Since D part in the area have alkali soil (pH 8.1), soil amendment is necessary for successful growth of trees and ground covers. When the area is filled or added with new soil for soil amendment, it will be important to use fresh soil which can support plant growth. It will be ideal to use ground covers and shrubs on the existing retaining walls along the street for keeping natural vegetation and slope stability instead of further cutting and reconstruction. It is not reasonable in technical and economic sense to remove rocks of the slope for planting trees. In order to harmonize plant color distribute, tall needle and broad leaf trees in the background as a screen, flowering trees were arranged in groups at front, and annuals were mass-planted along the footway. Natural-form-trees will be planted because they not only serve as a greenbelt but also are more economics in maintenance than formative trees.
