  • Adverse impact of Particulate Matters(PM10, PM2.5; PMs) significantly affects daily lives. Major countermeasures for reducing concentration of PMs were focused on emission source without considering spatial difference of PMs concentration. Thus, this study analyzed spatial·temporal distribution of PMs with observation data as well as potential contributing factors on PMs concentration. The annual average concentration of PMs have been decreased while the particulate matter warnings and alerts were significantly increased in 2018. The average concentration of PMs in spring and winter was higher than the other seasons. Also, the spatial distribution of PMs were also showed seasonality while concentration of PMs were higher in Seoul-metropolitan areas in all seasons. Climate variables, emission source, spatial structure and potential PM sinks were selected major factors which could affects on ambient concentrations of PMs. This paper suggest that countermeasures for mitigating PM concentration should consider characteristics of area. Climatic variables(temperature, pressure, wind speed etc.) affects concentrations of PMs. The effects of spatial structure of cities(terrain, ventilation corridor) and biological sinks(green infrastructure, urban forests) on concentration of PMs should be analyzed in further studies. Also, seasonality of PMs concentration should be considered for establishing effective countermeasures to reduce ambient PMs concentration.

  • Local government with abundant natural resources should consider the nature conservation oriented planning process for the sustainable development. With this regard, the aim of this study is to provide a substantial methodology to support the decision-making process to designate the conservation areas. The objectives of the proposed methodology is to conserve natural resources in the local government's territory through quantitatively assessing the values of the natural resources based on various ecological factors such as topography, flora and fauna. In order to test the usability of the method, Gangneung City in Kangwon-Do is selected considering the latest data availability. Based on the assessment process land use of the subjected city could be categorized into 4 levels of conservative area, conservative level 1 area, conservative level 2 area, and conservative level 3 area. Among them, conservative area and conservative level 1 area could be combined as natural resources conservation area and the others could be regarded as buffer and transitional area. Especially conservation area is surrounded by conservation level 2 area. Conclusively, the GIS methods adopted in this could be the efficient illustrative tool to assess the local natural resource values with the central government established nature-environmental information systems.

  • As the destruction of habitats due to recent development continues, there is also increasing interest in endangered species. Mankyua chejuense is a vulnerable species that is sensitive to changes in population and habitat, and it has recently been upgraded from Endangered Species II to Endangered Species I, requiring significant management efforts. So in this study, we analyzed the potential habitats of Mankyua chejuense using MaxEnt(Maximum Entropy) modeling. We developed three models: one that considered only environmental characteristics, one that considered artificial factors, and one that reflected the habitat of dominant tree species in the overstory. Based on previous studies, we incorporated environmental and human influence factors for the habitats of Mankyua chejuense into spatial information, and we also used the habitat distribution models of dominant tree species, including Ulmus parvifolia, Maclura tricuspidata, and Ligustrum obtusifolium, that have been previously identified as major overstory species of Mankyua chejuense. Our analysis revealed that rock exposure, elevation, slope, forest type, building density, and soil type were the main factors determining the potential habitat of Mankyua chejuense. Differences among the three models were observed in the edges of the habitats due to human influence factors, and results varied depending on the similarity of the habitats of Mankyua chejuense and the dominant tree species in the overstory. The potential habitats of Mankyua chejuense presented in this study include areas where the species could potentially inhabit in addition to existing habitats. Therefore, these results can be used for the conservation and management planning of Mankyua chejuense.

  • 본 연구에서는 서식지 질적 평가에 대한 추진체계를 6단계로 구분하고, 평가 대상지 선정 방법과 서식지 질적 평가 항목을 제시하였다. 서식지 질적 평가 항목은 서식지의 건강성, 안정성, 단절화 및 파편화 정도, 서식지 적합성, 위협 정도 등에 대한 종합적인 평가가 가능하도록 구성되었다. 그러나 현시점에서는 자료부족으로 인하여 서식지 질적 평가 체계가 적용 가능한 멸종위기종이 극히 일부에 해당된다. 서식지 질적 평가 체계는 향후 멸종위기종들에 관한 서식환경자료가 축적되고 이를 기반으로 평가항목들에 대한 정량적 기준 및 가중치가 부여되면 멸종위기종별 주요 서식지에 대한 보전방안 마련에 크게 기여할 것으로 기대된다.

  • This study is aimed at using the grasped problems of protected areas in Korea as the basic data for management planning and system improvement of protected areas by grasping realistic problems through the interview with the persons in charge on the basis of general problems of domestic protected areas. To this end, this study deducted major problems in urgent need of improvement, and improvement direction through the survey of the persons in charge of protected areas. This study result is as follows: The major problems, which should be preferentially improved, were found to be shortages of management infrastructure, cooperation between interested parties, and threat factors in protected areas, etc. Such problems are interconnected with each other, thus coming up complexly; therefore, it's necessary to make a comprehensive approach to the problems after confirming the causal relationship of the identified problems. In addition, for the purpose of effective management of a protected area, it's necessary to implement priority management of major problems through different management intensity from the planning phase. Also, it's important to enhance the effectiveness of planning by considering a possible potential threat factor in the outside of protected areas, and referring to the contents of the development plan for the relevant area in time of management planning. Lastly, there is the need for systematic improvement of an institution through thorough status review of the actual state of management planning fulfillment in order to increase the effectiveness of planning in a follow-up study hereafter.

  • This study aimed to classify damaged lands, to find what are the damage factors affecting the studied area, and to present a prescription in order to provide some benefit for the restoration of Regional Ecological Network at Chungnam province. Finally we classified damaged lands from 1st to 4th damaged lands according to relative intensity of damage. The main damage factors for the First Damage Lands were humus horizon, soil hardness and plant species richness. In the Second Damage Lands, those were soil hardness, plant species richness, number of plants and dominant plant species. In the Third Damage Lands, those were humus horizon, soil hardness, plant species richness, number of plants and dominant plant species. In the Fourth Damage Lands, those were humus horizon, organic matter, soil hardness, EC, T-N content, plant species richness, number of plants and dominant plant species. In every cases, the damage of soil and vegetation was originated due to development carried out by human being. The changes in soil condition were not big enough for it to affect plant growth, however, degradation of vegetation was still severe.

  • 가로정원은 서울시 가로환경 개선 사업의 일환으로, 보행자들에게 심미적 만족과 심리적 안정감을 제공하기 위한 휴식공간으로 설치되었다. 본 연구에서는 실제 가로정원이 이용자의 심리적 향상을 돕는지 고찰하기 위해, 가로정원과 이에 상응하는 비교대상지를 선정하여 설문조사를 실시하고, 결과를 비교하였다. 서울시에 위치한 총 9개의 가로정원 중 강남대로, 디지털로, 테헤란로에 설치된 가로정원을 대상지로 선택하였으며, 비교대상지로는 동일 대로상에 위치하며 물리적 환경이 유사하나 가로정원 사업이 시행되지 않은 3개의 장소를 선정하였다. 설문은 주의회복이론(Attention Restoration Theory: ART)을 근거, '매력감(Fascination), '벗어남(Being away)', '짜임새(Coherence)', '규모(Scope)'를 중심으로 구성된 회복환경지각척도-11(Perceived Restorativeness Scale-11) 질문과, 심리적 회복을 유도한 설계 요소를 묻는 질문으로 구성하였고, 요인분석, 신뢰도 분석, 독립표본 t-검정을 이용하여 분석하였다. 분석 결과, 가로정원은 이용자들의 심리적 회복에 비교적 긍정적 효과를 미치며, 특히 이용자들에게 매력감과 흥미로움을 부여한다고 나타났다. 그러나 가로정원은 이용자들에게 고단한 현실에서 벗어나는 듯한 느낌을 주지 못하여 심리적 향상효과의 한계를 드러냈다. 심리적 회복효과를 유도한 가로정원의 물리적 요소는 나무벤치, 나무, 꽃으로 나타나, 자연적인 요소가 인공적 요소보다 심리적 회복에 긍정적 영향을 준다는 심리회복 이론에 부합하였다. 본 연구의 결과는 향후 가로정원 사업을 추진함에 있어 계획 및 설계 가이드라인 개발에 기여할 것으로 기대된다.

  • 우리나라의 대부분의 골프장은 법적, 경제적 이유로 건설부지가 계곡과 능선 또는 봉우리를 포함할 수밖에 없는 실정이다. 계곡과 능선은 생태계에 있어서 매우 중요한 부분을 차지하고 있으므로 이를 훼손하는 것은 생태환경의 변화에 큰 영향을 미치게 된다. 따라서 골프장 공사로 인해 발생하는 훼손을 최소화하고 기존의 계곡 또는 하천이 하던 생태적 기능을 수행할 수 있는 생태복원형 하천을 환경보상적 차원에서 설치하는 것이 매우 중요하다. 본 논문에서는 골프장 내의 하천을 생태하천으로 복원하기 위해 고려해야할 사항과 적합한 공법 및 사례를 통하여 골프장건설로 인한 환경영향을 최소화하고 자연환경과 조화를 통하여 최적의 골프장을 조성할 수 있도록 설계도면 실례를 들어 제안하였다.
