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.

This study was conducted to establish a management plan for the Sangrim Woodlands restoration by analyzing the vegetation survey and the site characteristics of the Sangrim Woodlands Natural Monument (Natural Monument 154) in Hamyang-Gun, Gyoungsangnam-Do, Korea. According to the vegetation analysis, the species diversity by the location of Sangrim was higher near forest (1.000) than near urban (0.358) areas. Although forest occupied 53% of the Sangrim woodlands area, it is still insufficient, requiring to transform arable land, lawn, or house areas to the forest within the woodlands. Soil bulk density was increased in access areas frequently used by public, while it was decreased in closed areas. Soil hardness at 0-10 cm soil depth was generally improved in the closed areas, while became worse in the public access areas compared with the soil hardness in 2004.

This study aims to assess habitat feature on the large-scale spawning ground of the Boreal Digging Frog Kaloula borealis in Daemyung retarding basin of Daegu, and to analyze the relationships between species abundance and meteorological factors for each habitat. Fifty-seven(57) pitfalls were installed to collect species abundance of 4 survey regions, and high-resolution satellite image, soil sampling equipment, digital topographic map, and GPS were used to develop habitat features such as terrain, soil, vegetation, human disturbance. The analysis shows that the frog is most abundant in sloped region with densely herbaceous cover in southern part of the retarding basin. In the breeding season, lowland regions, where Phragmites communis and P. japonica dominant wetlands and temporary ponds distributed, are heavily concentrated by the species for spawning and foraging. Located in between legally protected Dalsung wetands and lowland regions of the retarding basin, riverine natural levee is ecologically important area as core habitat for Kaloula borealis, and high number of individuals were detected both breeding and non-breeding seasons. Temperate- and pressure-related meteorological elements are selected as statistically significant variables in species abundance of non-breeding season in lowland and highland regions. However, in sloped regions, only a few variables are statistically significant during non-breeding season. Moreover, breeding activities in sloped regions are statistically significant with minimum temperature, grass minimum temperature, dew point temperature, and vapor pressure. Significant meteorological factors with habitat features are effectively applied to establish species conservation strategy of the retarding basin and to construct for avoiding massive road-kills on neighboring roads of the study sites, particularly post-breeding movements from spawning to burrowing areas.

An invasive disturbance species has caused harm to biodiversity and ecosystem. To address the issue, identifying the characteristics of a habitat for invasive disturbance species is considered for forest management. This study analyzed a status of plant species by field survey based on belt transect method in the capital areas and established a predictive model for invasive disturbance species by logistic regression. As results of the study, the number of herb, vine, and invasive disturbance species and a canopy cover of tree would decrease from the forest edge to core areas (p<0.001). The predictive model was derived with variables of altitude, Topographic Wetness Index, distance to forest edge, and canopy cover of tree. It can be useful in estimating the presence or absence of species and predicting its spatial distribution. Further studies are needed to identify the pathway of introduction, spread, and possibility of germination for understanding the status of invasive disturbance species in more depth.

In this study, remodeling projects are perceived as a sustainable urban management policy to boost the value of old apartments and stimulate urban regeneration and development. To evaluate the physical environmental performance of external spaces of remodeled apartments, an evaluation model was developed. After applying it to the target places, the following results were obtained. First, analysis of the external space change index of the target apartments revealed that institutional standards are necessary in line with the building arrangement type, parking lot expansion method, and changes in the building-to-land ratio. Second, the score ratio as to the external space change index performance is as follows: safety (48.30); pleasantness (25.90); convenience (18.90); eco-friendliness (14.90). In other words, “safety” had the biggest score ratio. Third, to boost the external space performance of remodeled apartments, the needs of residents and neighboring environmental plans should be considered from a communality standpoint.

This study was carried out to the structure of plant community, and ecological succession sere of forest ecosystem in Soguemgang Valley, Odaesan National Park. Fifteenth plots(size is 20m×20m) were set up and the results analyzed by DCA which is one of the ordination technique showed that the plant communities were divided into seven groups which area community I(Quercus variabilis-Pinus densiflora community), Ⅱ(Pinus densiflora community), Ⅲ(Pinus densiflora-Quercus variabilis community), Ⅳ(Pinus densiflora-Quercus serrata community), Ⅴ(Quercus serrata community), Ⅵ (Pinus densiflora-Deciduous broad-leaved plant community), Ⅶ(Cornus controversa-Carpinus laxiflora community). Shannon diversity index per 400㎡ was to 0.7777 to 1.1440 and the age of Pinus densiflora 86 years old, Quercus variabilis was ranged from 66 to 87 years old, Quercus serrata was ranged from 51 to 62 years old, Carpinus laxiflora was 94 years old. In 2013, the succession trend was predicted Pinus densiflora→Quercus variabilis, Quercus serrata →Cornus controversa, Carpinus laxiflora. The ecological sucession progress has declined power of the Pinus densiflora and the increased power of the deciduous broad-leaved and Quercus spp. in Soguemgang Valley, Odaesan National Park. Quercus serrata and Quercus variabilis communities that judged Pinus densiflora were progressing by direction of landform. The southern slopes vegetation were progressing for Quercus variabilis, the northern slopes vegetation were progressing for Quercus serrata. In flat Valley, mainly native species of Cornus controversa, Carpinus laxiflora are predicted ecological succession for deciduous broad-leaved tree community.

This study introduced wood waste into revegetation base materials for recovery of highway cut slope. The object of this study is to derive the mixing ratio of wood waste, kaoline and silica by conducting a test installation, monitoring, analysis and evaluation. The following items were investigated and analyzed each experimental zone to deduce the mixing ratio of wood waste, kaoline and silica on slope revegetation base materials: the physical and chemical properties of the vegetation base materials, soil-hardness, soil-humidity, collapse and eroded spots, established number of trees, existing species of grass and tree species, vegetation coverage ratio, pest status, and invasion of disturbance species. The revegetation method was evaluated in each experiment zone which had different mixing ratios. As a result, experiment zone C scored 47 points out of 60 as the best revegetation method. However, this result has been derived from just one construction and short-term monitoring. In order to derive the suitable and dependable mixing ratio, conducting an objective revegetation method evaluation and long-term experimenting and monitoring is required.

The objectives of this study were to establish the slope criteria and analyze the forest land restoration plan in North Korea. Reviewing the literature of the countries, the relationships among the climate, erosion controls, and slope criteria with forest restoration programmes, implemented were analyzed. Comparison of forest land management policies was conducted between South and North Korea. The soil erosion controls using biological barriers were at 15~20°slopes in arid climate regions and 25~30° in humid climate regions. In the case of South Korea, an afforestation policy from the「Act on Clearance Project of Slash-and Burn Agriculture」of 1966 was enforced on mountains with slope greater than 20°, however, at present, the「Marginal Cropping Land Policy」recommends cropping lands with slope bigger than 8.5° to forest land. In 1961, in「Land Reclamation of One Million Hectare」, North Korea reclaimed additional cropping lands with slope bigger than 8.5°, and currently, the「Act on Forestry」states to enforce reforestation with slope bigger than 20°. This study recommends that South Korea aids for forest land restoration in North Korea based on the different stages of their development on reconciliation and cooperation between South and North Korea.
