  • This study was carried out to lead the scientific management of the urban forest by estimating the forest environment. Forest environmental information was constructed using IDRISI system based on survey data, soil, plant, and digital elevation data. Forest environmental information was consisted of soil depth, soil organic content, soil hardness and parent rock as a soil environmental factor, and forest community, tree age, crown density as a plant environmental factor. Plant activity and topographic environment also were analyzed by using remote sensing data and digital elevation data. Environmental function of urban forest was estimated based on results of soil conservation and forest productivity. 70% of urban forest is located in elevation of lower than 200m and 55% of forest area have the slope of lower than 15 degree. Analyzed soil conservation status and forest productivity were almost the same as the soil chemical properties of collected soil sample and the vegetation index estimated using remote sensing data, respectively. Thus, the constructed forest environmental information could be useful to give some ideas for management of urban forest ecosystem and establishment of environmental conservation planning, including forests, in Taejon. The best forest environmental function was appeared at the natural ecology preservation zone. Current natural parks and urban parks were appeared to establish the environmental conservation plan for further development. The worst forest environmental function was appeared at the forest near to the industrial area and an overall and systematic plan was required for the soil management and high forest productivity because these forest was developing a severe soil acidification and having a low forest productivity.

  • The importance of the green space in urban area has been increasing. There are the increasing needs of creation and sustainable management of urban forest. In order to satisfy the need, it is necessary to set indicators for sustainable urban forest. With this regard, this study is to derive the indicators for evaluation of the urban forest through literature reviews, experts opinion, and field survey. The results of the study, the indicators consist of the ecological healthiness, socio-cultural function, and scenic beauty. The ecological healthiness includes stability and naturality (e.g. area, native species, connectivity etc.). The socio-cultural function contain improvement of living environment, stable emotion, community, and environmental education. The scenic beauty includes environmental-friendly facilities, maintenance of urban forest. The indicators have high feasibility to create and manage the urban forest through evaluating urban forest in practical. This indicators are useful to guide to develop urban forest and park.

  • In broad agreement on the need for forests in the city, researches on the urban forest are being actively carried out. Nonetheless, since these researches focus on functional usage within living spaces, finding methods for creation of urban forests and technical solutions have remained chief issues as a consequence. This paper, which attempts to historically examine the properties of the urban forest within living space, has the characteristics of researching basic angles for approaching the creation of contemporary urban forests. For this purpose Joseon Dynasty genre paintings, which represent living conditions of Joseon era, have been decided as theme of the paper. Particularly the focus was limited to genre paintings depicting trees, giving phenomenal observations. As a result, some remarkable characteristics emerged as functional urban forest, symbolic urban forest, topological urban forest, and appreciative urban forest. Urban forest within living space mainly appear as functional, showing an even distribution in small numbers rather than gathering in large groups. The following can be inferred regarding this and related to the setting up of the scope of, and creating of, contemporary urban forest : First, from the viewpoint of urban forest creation there is a need to study more subdivided and refined types of the urban forest and to actually realize these types. Second, from the viewpoint of urban forest usage, one needs to approach existing forests, ranging from small-scale including invididual trees, to mid-, large-, and super scale, as urban forests. In this, a network of major trees, and thereby a matrix of all trees formed by that network, will be formed. Third, from the viewpoint of urban forest improvement, approaches need to be based on planting trees in even distribution across the whole city.

  • This study is focused on finding out the character of urban recreation forest and investigating facilities regulations of forest resources around urban areas to meet future recreation needs. The method of this study is to compare urban recreation forests with similar facilities like urban parks and natural recreation forests. By this way, this study not only identifies the characteristics of urban recreation forest as emerging recreational facility, but also outputs regulations that can be adapted to real environment. Urban recreation forest is defined as follows: It has forest with good natural landscape and easy access. It makes emotion rich and its function is focused on outdoor recreation nature education, and experiences for family group mainly within a day or on weekends. This study suggests that the minimal area of urban recreation forest should be over 100,000$m^2$, with a facility ratio less than 20%. Building coverage should be less than 7% when the urban recreation forest is under 300,000$m^2$, less than 5% when 300,000∼500,000$m^2$, and less than 3% when over 500,000$m^2$ The limits of building height is 3 stories, or under 12m. This study finds out the character, the needs of urban recreation and the criterion for project feasibility. significance of the result is supplying theoretical basement on related regulation. Based on the results, further study will establish landscape management method and legislation & application in a detailed examination.

  • The objective of this study is to review and verify whether the functions and effect of roadside trees generally hewn in theory are actually realized in urban roads and how well they are performed if the function and effect are realized. The study was conducted with a focus on 3 functions and effects including roadside tree's urban landscape improvement function (green area visibility ratio), effect of introducing green area within a city, and urban green network building function. The major study results are as follows: First, the average green area visibility ratio of 41 study areas is currently about 25.90%. The green area visibility ratio of commercial area within downtown was lowest among 5 road types. It showed that it is possible to raise the average green area visibility ratio up to 32.49% through roadside tree management and additional plantation. Second, in a section between Paldal Mountain and Suwon City Hall where there is no forest fragments and parks at all, a green area of 4,826 roadside trees represented 2.4% of total area and served as the only linear green area. Third, an analysis of 15 cities in Kyonggi province showed that urban forests are concentrated in outskirts. The suey showed that because forest fragments and parks exist in a form of points in urban areas, roadside trees are the only green areas that link each other and build a network.

  • In urban area, urban forests work as an ecological center that mitigates the environmental pollution of the area. In order to maintain the ecological function of a forest, the management method should be established based on ht through investigation of the vegetation structure of the forest. In this study, the vegetation structure of Namsan in Kyungju area was investigated in order to study the ecological value of Namsan and to suggest a desirable management alternative. 21 plots were selected as survey areas. Using the TWINSPAN technique, the forest of Namsan was classified into four communities: Quercus serrata community(I), Castanea crenata-Q. serrata-Q. mongolica community(II), Pinus densiflora community(III) and P. densiflora-P. rigida-Robinia pseudoacacia community(IV). The survey results were summarized by five: 1) the distribution of vegetation showed 2) P. densiflora was the absolutely dominant species in Namsan, 3) number of the average species was 12.6$^{\circ}$$\pm$3.1, 4) number of individual was 131.1$^{\circ}$$\pm$47.8 per a plot(100$m^2$), 5) the results of annual ring analysis revealed that the age of P. densiflora in Namsan was about 3 0$^{\circ}$~60$^{\circ}$years old. From the above results, it was found out that the forest has two problems. One thing is maintenance of P.densiflora against succession, another is artificial forest dispersion. The problems of Namsan forest management will be solved with further studies related.

  • 본 연구는 서울과 경기도 지역 도시숲의 수자원 공급 생태계서비스와 기후완화 생태계서비스를 평가하였다. 생태계서비스를 자연기능기반 서비스, 산림의 자연기능과 인구분포를 고려한 생태계서비스, 산림의 자연기능과 수혜자 분포를 고려한 생태계서비스의 세 가지 서비스로 구분하여 평가하고, 이후 기후변화가 생태계서비스에 미치는 영향을 평가하였다. 평가 결과, 토지피복과 토양 등 자연조건을 반영한 도시림의 수자원 공급서비스의 경우, 경기도가 서울보다 높은 서비스를 제공하는 것으로 나타났으며, 지역별 인구분포를 추가적으로 반영한 서비스 평가에서는 인구가 많은 곳에서 서비스가 높게 나타나는 양상을 보였다. 그러나 도시림의 수자원 수혜자 분포를 추가로 반영한 수자원 공급 생태계서비스 평가 결과는 인구분포를 반영한 서비스 평가 결과와 공간적으로 다르게 나타났다. 같은 수원함양 기능을 가진 지역이라도 인구분포나 물 사용 수혜자의 분포가 많은 지역일수록 높은 서비스 결과가 나타났다. 또한 기후변화가 수자원 공급 생태계에 서비스에 미치는 영향을 평가한 결과, 기후변화에 따른 수자원 공급 서비스는 평균적으로 26%정도 줄어들어 전반적인 수자원 공급 생태계서비스가 낮아지는 경향을 보였다. 기후완화부문의 경우, 산림으로부터 가까운 거리에 있을수록 높은 온도저감 효과가 나타나 산림주변지역에서 높은 기후완화서비스가 나타났으며, 기후 완화 서비스의 수혜자 인구를 고려한 생태계서비스 평가에서는 수혜인구의 밀도가 높은 서울 도심지역에서 높은 서비스가 나타났다. 기후변화에 따른 산림 생장량 변화를 반영하여 산림의 기후완화 생태계서비스의 변화를 평가한 결과, 평균적으로 약 33%의 서비스 감소가 나타났다. 본 연구의 결과는 도시림을 관리하기 위해서 산림청에서 제시하고 있는 공급기능기반의 6가지(자연환경보전, 산지재해방지, 목재생산, 산림휴양, 생활환경보전, 수원함양) 기능구분 외에 서비스를 수혜하는 수요자 기반의 기능 및 서비스가 평가의 필요성을 제시한다. 이는 기존의 산림의 공급기능기반의 평가에서 간과할 수 있는, 자연기능은 낮지만 수혜를 받는 시민들이 많아 높은 서비스 가치를 갖는 산림을 재평가하고 올바른 관리 계획을 수립하는데 기여할 수 있을 것으로 판단된다.

  • This study was carried out to analyze water cycle characteristics and evaluate water retention function in Jeju Gotjawal forest from 2013 to 2017. The average ratio of throughfall, stemflow, interception loss in Seonhul Gotjawal (SH) and Cheongsu Gotjawal (CS) was 43.1%, 15.8%, and 41.1%, respectively. Rainfall-throughfall, rainfall-stemflow, and rainfall-interception loss were expressed as linear regression equation (p<0.001). The comparison results showed that SH was higher than CS (p<0.05), indicating that the canopy area had an important effect on the difference in stand structure. The average water resources retention rate of the Gotjawal region was 41.9%, which is similar to the total water resources retention rate (40.6%) of Jeju Special Self-Governing Province (JSSGP). Currently, the development of Gotjawal is in progress in JSSGP. The development of Gotjawal will lead to a decrease in the water resources retention rate due to changes in the surface environment such as an increase in impervious areas, which will affect the total groundwater content of JSSGP. Therefore, the conservation of the Gotjawal area is judged to be very important from the point of view of water conservation.

  • 도시림 개선을 위한 노력은 꾸준하게 진행되어 왔으나 사회적인 욕구를 제대로 반영하였는지에 대한 평가가 없어 향후 지속적인 개선 및 관리의 방향을 제안하기는 어려운 상태이다. 사회환경과 생물환경이 어우러진 도시림을 효율적으로 개선하기 위해서는 양적 증대 뿐만아니라 생물의 분포 및 서식, 인간의 이용성을 평가할 수 있는 연결성, 건전성, 접근성 등 질적인 측면을 동시에 고려할 수 있는 생태적 건전성에 대한 평가지표의 필요성에 따라 연구를 진행하였다. 연구는 생태적 건전성 평가시 중요한 항목에 대한 상대적 중요도 평가, 문헌고찰을 통한 세부 지표 선정, 타당성 검토의 체계를 갖는다. 결과적으로 도시림은 자연림과는 다른 기능이 존재한다는 전제로, 도시림 평가는 고유의 기능인 생태성 뿐만아니라 인간의 간섭을 고려할 수 있는 사회성, 관리성이 충분하게 고려되어야 하나 중요도에 대한 설문조사 결과 생태성이 다른 가치에 우선하는 것으로 나타났다. 이에 생태적 건전성을 평가할 수 있는 세부지표를 선정하였는데, 식생관련 지표로는 희귀성, 훼손잠재성, 자연성, 면적, 다양성, 발생기간, 야생조류관련 지표로는 숲 발달정도, 면적을 추출하여 분산분석을 실시한 결과 안정성, 자연성, 다양성, 잠재성, 서식가능성이 평가지표로 선정되었다.
