본 연구에서는 경남 거제시 구천 천을 대상으로 생태하천 조성공사의 시공 성을 분석하고 평가하였으며 다음과 같은 결론을 얻을 수 있었다. 첫째, 구천 천 생태하천 조성공사의 시공 성 평가를 위한 평가지표를 설정하였다. 일반적인 공사품질 평가항목에 본 연구대상지의 공사특성을 감안하여 설계품질과 건설행정부문을 더하여 평가지표를 설정하였다. 크게 대 분류로 공사 품질, 설계품질, 건설행정으로 나누었으며, 중분 류로는 식 재, 시설물, 포장, 급배수공사, 설계 전 문성, 설계도서, 기술시방서, 공사기간, 적정 비용, 참여자인식 등 10개 유형으로 구분하고 소 분류의 평가항목은 해당공사의 세부적 내용으로 구성된 총 20가지로 구성하였다. 둘째, 시 공성 평가결과, 평가항목별로는 급 배 수공사, 석재공사, 포장공사, 식재공사 순으로 시 공성 개선의 필요성이 제기되었으며, 평가 대 상으로는 묵논습지 조성공사와 완경사 저수 호 안공사에서 시 공성이 낮게 평가되었고 수달서 식 처와 자연경관보전 구간은 비교적 적정한 것으로 평가되었다. 설계도면의 누락과 기술시방 의 문제, 시공참여자의 인식문제에 대해서는 개선필요성이 다소 있는 것으로 나타났으나, 설계 개념의 적정성 부문은 참여기술자의 대부분이 적정한 것으로 평가하였다. 셋째, 문제점에 따른 개선방안 제시로서, 품 질 관리에 의해 개선될 수 있는 사항으로 무논 습지조성에서의 유입 수, 유출 수 연결 관의 마감 처리, 논흙처리에 대한 방안과 하천에서의 저수 호 안 돌 쌓기 시공성과 석재공사의 마감처리 등 이 있으며, 동 분야의 기술적 한계점으로서 연 구가 필요한 부분으로는 생태수로의 돌 쌓기 이 음 새 부분의 콘크리트 몰탈처리와 천변수림대 의 폭 원 설정 등을 들 수 있다. 하천 코 리더의 생태적 역할을 수반하는 천변수림대의 폭 원 및 식생의 기능에 대한 연구는 향후 하천 변 생태 복원공사의 기술력 향상을 위한 현실적 대안이 될 수 있을 것이라 판단된다. 그 이외에도 시공 과정에서 설계자와 지속적인 논의와 피드백 과 정이 필요한 속성을 가진 공사라고 판단되며 향후 생태복원공사의 전반에 걸친 시공 성 평가 의 기법이 지속적으로 개발되어야 하겠다. In this study, constructability of ecolog ocal stream restoration process was evaluated and improved approaches for habitat were suggested. The study site is Gucheon River in Geoje city where conducted ecologocal restoration work within maintaining its flood control function. Application of ecological design factors and constructability in the process from planning to construction was analyzed and its results are as follows: In the process of planning and designing, it was focused more on the naturality of Gucheon River rather than the human convinience and ecological design factors were applied within the ecological capacity of the site. First, the indexes for constructability evaluation is selected. It was classified into three major categories as construction quality, design quality and construction administration system. Each index has details, so there are twenty sub indexes for contractibility evaluation. Second, the evaluation results shows that the index most in need of improvement was plumbing construction, followed by Stone construction and pavement construction. design concept was evaluated as appropriate in entire categories. Finally it is suggested that it can be improved in both process of design to enhance the technology and process of construction to enhance the quality management. The constructability of ecological stream needs adaptive management and it must be discussed with its designing which is at the stage before construction. Also it needs discussion with its designer constantly and feed-back process.

Numerous studies suggested that fish assemblage structure reflects the status of stream ecosystems. The status of streams integrity, including various trophic levels, water quality and habitat degradation, can be assessed by fish assemblages. In this study, we investigated the relationships between fish assemblages and streamline geometry of streams. Previous studies suggested that geomorphologic parameter can be a critical factor of permeability between adjacent two systems. From a landscape ecological perspective, edges may partially control the flow rate of energy between two adjacent systems, Thus, the Streamline geometry can be a geomorphologic parameter that exhibits the integrity of stream, We selected the Nakdong river for study areas, which is one of major rivers and the longest (525 km) River in South Korea, We used the revised IBI representing overall ecological characteristics of Korean fish assemblages and eight sub-assessment criteria of IBI, collected from 82 sampling sites in the Nakdong River. For calculating the Streamline geometry, we measured fractal dimension index that generally used in biology, ecology and landscape ecology. We used the digital land-use/land-cover map and generated a 1-km buffer for each sampling site and refined the shape of the Streamlines. Pearson correlation analyses were performed between Streamline geometry and IBI and sub- assessment criteria of IBI. The results show that IBI and eight sub-assessments of fish are significantly correlated with geometry of Streamline. The fractal dimension of Streamline geometry were related with IBI (r = 0.48) and six sub-assessments of IBI, including total number of native fish and native species, the number of riffle benthic species, sensitive species, tolerant species and native insectivore. Especially, the number of tolerant species(r = -0.52) and native insectivore(r = 0.52) show strong correlation with geometry of Streamline. These results indicate that lower Streamline geometry can result in poor fish assemblages, while higher geometry of Streamline can enhance fish assemblages by potentially supplying insects and better habitat conditions. We expect the results of our study to be useful for stream restoration and management. However, we see the necessity of study investigating the mechanisms how Streamline geometry affect fish assemblages.

The street canyon forms the geometric unit of the built environment. The geometry makes up urban canyons and it influences the urban climate. In order to investigate the wind characteristics of urban street canyon at Dogok-dong, Gangnam-gu in Seoul, the wind direction and wind speed data were observed and analyzed by using 2-D ultra sonic and propeller wind monitor from May 5, 2010 to May 4, 2011. The results show that the prevailing wind direction was west at Station A(Military Mutual Aid Association Building), southwest at Station B(Sookmyung Girls`` High School) and the wind speed of Station B was higher than Station A. There were diurnal differences about prevailing wind direction between two stations:it was westerly wind at Station A for a whole day, but at Station B only from 22:00 to 04:00. However, Station B is different from Station A at other time. At Station B, it was easterly wind from 04:00 to 12:00, southwesterly wind from 12:00 to 22:00. In terms of seasonal (except winter) frequency, the spring shows the highest frequency and fall was the next.

Vegetation index information is an important figure that is used in many fields such as landscape architecture, urban planning, and environment. Vegetation may vary slightly in vegetation vitality depending on photosynthesis and chlorophyll content. In this study, a range of vegetation worth preserving in the Taehwa River water system was determined, and hyperspectral images of drones were acquired (August, October), and the results were presented through DVI(Normalized Defference Vegetation Index), EVI(Enhanced Vegetation Index), PRI(Photochemical Reflectance Index), ARI (Anthocyanin Reflectance Index) index analysis. In addition, field spectral data and VRS-GPS(Virtual Reference System-GPS) surveys were performed to ensure the quality and location accuracy of the spectral band. As a result of the analysis, NDVI and EVI showed low vegetation vitality in October, -0.165 and -0.085, respectively, and PRI and ARI increased to 0.011 and 7.588 in October, respectively. For general vegetation vitality, it was suggested that NDVI and EVI analysis were effectively performed, and PRI and ARI were thought to be effective in analyzing detailed characteristics of plants by spectral band. It is expected that it can be widely used for park design and landscape information modeling by using drone image information construction and vegetation information.

This study is carried out to find the most optimal soil- plant combination in the urban agriculture by analyzing the association of soil base material which is being used in the urban agriculture with the growth of plants. 4 types of easily purchased soil (bed soil(A), animal vermicast soil(B), earth worm soil(C) and matured compost(D)) verified in aspects of effect and safety of soil in terms of growth of crop is selected as experimental soil and B, C, D type soils are mixed with granite soil at the ratio of 7:3. And granite soil (E) is set as a controlled soil and is compared to verify the effect of the experimental mixed soil. Herbaceous plants are classified into the fruit vegetables (Lycopersicon esculentum Mill, and Capsicum annuum L.), leafy vegetables (Brassica campestris L, ssp, Pekinensis and Lactuca sativa L.), medicinal vegetables (Chrysanthemum zawadskii var, latilobum and Liriope platyphylla F, T, Wang & T, Tang), The results of comparison of growth of herbaceous plants in different soil types showed that fruit vegetables and leafy vegetables in general had excellent growth in D type soil mixture and Atypesoil in general and had the poorest growth in E type (controlled) soil. ``Chrysanthemum zawadskii var. latilobum`` had the excellent growth in D type, B type, C type mixed soil and A type soil and E type (controlled) soil are followed in order. In the case of ``Liriope platyphylla F. T. Wang & T. Tang``, the difference in growth by each soil was shown to be insignificant. Therefore, the soil applied in the urban agriculture varies depending on each species of herbaceous plants, but it is considered effective to cultivate herbaceous plant which is economical and productive by using D type mixed soil which can be recycled and inexpensive compared with other experimental soils in the urban agriculture.

Urban Green Area has ecologically deteriorated along with quantitative loss, being developed as a dot itself rather than connected to forests and green networks around the park. The present study aims to propose a connected plan on Urban Ecological Network establishment through ‘assessment of the connectivity of the entire urban parks`` in accordance with distance of forest and river and ‘assessment of trends in connection fragmentation of urban parks`` in accordance with the past change of forest and river. According to the result of this study, criteria based on previous research was “directly linked type is less than 300m, conceptually linked type is between 300m to 1km, the isolated type is greater than 1km”. And the result of ‘assessment of the connectivity of the entire urban parks`` is analyzed as the rate of park and green network, 41.7% in Suwon, 80.0% in Seongnam, 88.9% in Namyangju on the basis of office and field investigation. Also, according to the result of ‘assessment of trends in connection fragmentation of urban parks``, consideration for connection to the original forest is insufficient.

Kaloula borealis is the species of Amphibia which belongs to Kaloula genus and it is the only species inhabiting in Korea. The population size and habitat of Kaloula borealis have been significantly decreased on a national scale due to the diversified developments and the uses of agricultural pesticides. Accordingly, the Ministry of Environment has designated and managed them as the class II of endangered species, in accordance with ?Endangered Species Protection and Management Act?; however, a particular study focused on the ecological restoration of Kaloula borealis is desperately needed to prevent their extinction. This study was conducted to propose the HSI (Habit Suitability Index) of Kaloula borealis based on literature survey on ecology and habitats of Kaloula borealis, as well as their HSI. Factors to be investigated in HSI include: space, feed, cover, water(breeding) and threatening factors and the variables of each factor were also proposed. The distance from wetland, grassland, farm, stream and rice paddy, as well as the altitude of spawning pond were proposed as the variables of space, whereas the bed structure of forest and low-rise grassland were proposed as the variables of feeding. The variables of water (breeding) include the area of permanent and temporary wetlands, coverage of emerged pants (ratio of open water), water depth, water temperature, water quality, pH level, etc., whereas the presence of predator, distance from street and pollutants were proposed as the variables of threatening factor. The sub-standards by HSI factor of Kaloula borealis have been drawn from in-depth consultation with experts and based on this, the final HSI of Kaloula borealis was developed.

Recently the countries breeding bears such as China and Vietnam are promoting a policy that gives relief to wild animals through agreement with AAF and WSPA. Currently our country has lacking breeding space for the increased number of bred bears due to the prohibition of bear import and export from joining the CITES in 1992. There needs to be a place that treats, protects.accepts breed bears in the terms of animal welfare. The bear park was hoped to be designed as a means to give relief to bears and promote harmony with the local society, and is made of parking area, waiting area, visitors center, treatment·research·management facilities, restaurants, food warehouse, food store, bear museum, sanitation facilities, gondola, plaza, rehabilitation area for wild animals, outdoor exhibition center, direct·indirect experience area of wild animals, resting facilities and areas, photo zones, bear playground, bear experiencing facilities, fences, information facilities, tree protection facilities and more. The design can be used as a reference in examining alternative measures following the future change in breeding policy as a bear park example which reflected the ecology of a bear in the term of animal welfare.

The Environmental Conservation Value Assessment Map (ECVAM) is a five grade assessment map created with nationally integrated environmental information and environmental values. The map is made through the evaluation of 65 items, including greenbelt area and naturalness. Naturalness means original state of nature, and it is one of the most important evaluation items for conserving nature, The criteria of naturalness includes the Degree of Green Naturality (DGN) made by MOE, Using the data which has been not updated is a problem of accuracy for ECVAM. Therefore, this study would like to improve the criteria of naturalness. To improve the criteria, the study examined the effectiveness of DGN using field survey. The results of analysis the naturalness without DGN, some area changed grade of naturalness have been already damaged or cleared for agriculture and industrial purposes. The grade of naturalness should be included the concept of vegetation transition like DGN. The study suggested a improved method using vegetation type (natural and planted forest), forest age, and the grade of vegetation conservation. The method was reviewed by experts and field survey. After applying the method in South Korea, the grade of naturalness were distributed evenly like GradeⅠ is 38.87%, GradeⅡ is 37.62%, GradeⅢ is 23.51%, respectively. From the results of field survey, over 4 grade of forest age in natural forest showed similar pattern of structure and composition in original forests. Therefore, the improved criteria explained the naturalness better than existing criteria, and the accuracy of ECVAM has been improved more.

Landscape space can and should play as a multi-functional agent: healing contaminated soil, reducing natural hazards, supporting living things, making comfortable environment for human, and appealing to human aesthetics, etc. This article aims to show the possibility and role of landscape space as such agent. In landscape design for National Marine Biology Resource Institute, distributed rain water treatment system and rain gardens are introduced to replace a mono-functioning large detention pond which was suggested by disaster impact assesment. Phytoremediation and vegetation filtering system with muti-cell wetlands are also adapted to heal the contaminated soil. This kind of landscape as a ``living machine`` which can play as an operational control utility of multi-environment and thus can be combined effectively into green infrastructure is important for post-industrial city, especially in an era of climate change.
