본 논문에서는 도심공원이 증가하고 환경의 생태적 가치가 높아짐에 따라 생태공원의 존재가 부각되고 있는 현실 속에서, 국가에서도 필요성을 인지하고 있는 생태공원이 점차 확대되어감에 따라 도시림의 문제점을 알아보고 서울숲의 기능과 생태적요소를 알아보고 향후 도시림의 설치방향에 대해 제시하고자 한다. 현재 국내 도시림의 문제점을 도출해 낸 후 서울숲의 기능과 생태적 요소를 비교분석하여 국내의 도시림이 가져야할 기능과 요소들을 파악해 향후 도시림에 그러한 기능과 요소를 도입시켜 국내 도시림이 더욱 생태적인 공원이 될 수 있을 것이다.

This study analyzes the correlation between noise and the size of urban forests. Under the assumption that the main cause of the noise m the city is the population density, the size of urban forests per capita and the ratio of urban forests with respect to the size of urban per 100 thousand persons are used for the calculation of correlations with noise. The results of the calculations of Pearson's and Spearman's correlation coefficients indicate that the increase in the size of urban forests has a significant effects in reducing the day-time as well as night-time noise for most regions in the cities. The size of urban forests within public parks has a significantly negative correlation with the noise. However, calculated correlation coefficients imply the increase in the size of total urban forests is more effective in reducing the noise than the increase in the urban forests in public parks.

기존 연구 문헌의 고찰로 서울시 야생조류상의 현황 및 관리방안은 다음과 같이 결론지을 수 있다. 1. 서울시 야생조류상에 대하여 물새와 산새를 모두 연구한 결과가 아직 발표되지 않아 정확한 현황은 파악하기 어려우나 번식기에는 약 40 여종, 겨울철에는 40여종이 서식하는 것으로 볼 수 있으나, 앞으로 정교하며 지속적인 모니터링이 필요하다. 2. 도시림 뿐만 아니라 주변의 패치를 동시에 고려한 통합적 접근방식(intergrated approach)으로 도시림을 연구하여 관리해야 할 것이다. 3. 도시림의 면적은 도시림에 번식하는 야생조류의 종 수에 큰 영향을 미치는 지배적인 인자로써 도시림이 더 이상 다른 토지이용 형태로 전환되지 않도록 관리하는 것이 가장 기초적인 관리 지침이다. 4. 대면적의 숲이 세분화 될 경우, 여름철새의 번식에 지장이 있을 수 있으므로 대면적 숲의 세분화를 막아야 하며, 가능한 한 생태통로(eco-corridor)로 세분화 된 숲을 연결할 수 있는 기술을 개발해야 할 것이다. 5. 도시림에 생육하는 임목 중 대경급 임목은 나무구멍을 둥지자원으로 이용하는 조류의 중요한 은신처와 둥지이므로 대경급 임목을 대신할 수 있는 인공새집의 설치는 나무구멍을 둥지로 이용하는 조류의 번식 종 수를 높이는 방법이다. 또한, 도시림이 시민에 의해 과도하게 이용될 경우, 관목층이 제거되어 관목층을 둥지자원으로 이용하는 조류의 서식에 불리한 조건을 제공할 수 있으므로 등산로 주변에 관목성 수목을 밀식하여 등산로의 확폭과 파괴를 막아야 할 것이다. 풍부한 먹이 자원을 제공하기 위하여 관목층 보호를 꾀하고 임목의 조림과 무육에 힘써야 할 것이다. 6. 동일한 면적에서 번식 조류 종 수를 높이는 방법은 엽층의 피도량을 늘이는 것이다. 현재 서울의 도시림은 엽층의 분화보다는 우선, 피도량의 증가를 위해 노력해야 하며 후에 엽층의 다양성을 높여 산림의 수직적 구조를 다양하게 만들어야 할 것이다. 7. 들고양이와 들개에 의한 소형 조류의 피해가 늘고 있으므로, 야생조류의 천적인 들고양이와 들개를 구제해야 할 것이며, 이에 앞서 서식실태가 조사되어야 할 것이다. 8. 한각을 비롯한 지천의 하변에 서식, 월동하는 물새류와 서식지에 대한 연구와 관리가 시급히 이루어져야 할 것이다. 9. 산불방지와 도시림 정비의 일환으로 실시해 온 관목층과 낙엽 및 죽은 가지를 제거하는 비과학적인 관행과, 하천유지유량을 높이고 하변 정비 및 산불 방지으 ㅣ한 방편으로 진행된 하변 식생 제거는 전문가와 충분히 제고한 후, 없어져야 할 것이다.

The purpose of this study is to estimate air purification effectiveness considering the improvement of its methods related atmospheric environment. The air purification effectiveness is estimated in Daegu, one out of Korean Metropolitan cities because air pollution is getting serious in a heavily urbanized area. The absorption of pollutants is calculated by considering spatial heterogeneity that was not considered previous studies and the spatial resolution of air dispersion modeling is also improved by kriging method. According to the type and distribution of urban forest, total 26 kinds of plant communities were distributed with Pinus densiflora community, Pinus densiflora-Quercus mongolica community, Pinus densiflora-Quercus acutissima community and other kinds of communities in the study area. In the results of estimating the $CO_2$ absorption amount for identification of the air purification effectiveness on urban forest, the annual absorption amount was total 108,155t/yr. Also, the annual absorption amounts of $NO_2$ and $SO_2$ were total 183.5 ton and 410.2 ton respectively. The findings from this study can confirm the differences of pollutant absorption by concentration that could not identify if spatial distribution of pollutant concentration had not been considered.

The purpose of this study is to investigate if subjective well-being could be improved by visiting urban forests near residential areas. Because visiting an urban forest is not an intense positive experience, this research is focused on frequency of affective experience rather than intensity. The independent variables are number of visits and length of stay. The dependent variables are positive affect, negative affect, and life satisfaction. A polling agency was employed to select 600 respondents by quota sampling, and data was collected by online survey. The results of ANOVA showed that there was no interaction between the number of visits and length of stay. Regardless of the number of visits, the subjective well-being of visitors of urban forests was enhanced: (a) positive affect of respondents who had visited in the past 2 weeks was increased while negative affect was decreased, and (b) life satisfaction for those who had visited at least 1 time per month was enhanced among usual visitors. The stay of length, however, had little effect on the increase or decrease of these three variables. The results of this study support the existing theory that one could reset their genetically determined happiness set point to a higher level by participating in intentional activities such as visiting urban forests that offer ways to achieve long-lasting changes in well-being. This means that it would be a valuable government investment to construct and maintain urban forests for improving citizens' welfare. A few comments were suggested regarding data collection and inclusion of influencing variables to make future subjective well-being studies more reliable.

This study was analyzed between actual vegetation type and 4 Paridaes of Korea (Great tit Parus major minor, Marsh tit P. palustris hellmayri, Coal tit P. ater amurensis, Varied tit P. varius varius) in the urban forests in Seoul. The population size of total Paridaes was highest in Robinia pseudoacacia community. When supposed the same area for revision of the difference of each type, the population size was highest in Alnus hirsuta community. The next orders of total observed population was Alnus hirsuta - Pinus desniflora - Quercus acutissima - Castanea crenata. In the urban forest, Paridaes are looks not affected by the naturality of vegetation but other key figure.

The aim of this study is to clarify the psychological effects of walking in the urban forest and to examine how the effects differ in accordance with individual personality. The study subjects comprised 18 male Japanese university students ($21.0{\pm}0.8$ years old). These subjects were instructed to walk predetermined 20-min courses in the urban forest and the city (control). Three questionnaires (POMS, STAI-S, and SCL-90) were administered to assess the subjects' psychological responses. The KG's Daily Life Questionnaire was used to examine the subject's personalities for presence of the Type A behavior pattern. The study found that walking in the urban forest improved the participants' positive mood and decreased their negative mood, anxiety, and other negative mental symptoms. Moreover, Type B subjects showed a bigger change than Type A subjects on the SCL-90's obsessive and compulsive scale. Our results supported the premise that walking in the urban forest has relaxing effects, and that these effects can differ in accordance with the subject's personality characteristics.

This study is analyzed on user's activities and recreational value through a questionnaire on users of the forest road in urban forest. Users visiting the forest road in urban forest went to there about three times a week, and the re-visit intention was showed highly. The forest road in urban forest is used too much for the promotion of health as a walk and a mountain pass of the citizen, and they think that forest road is useful for forest recreation. The satisfaction grade on forest road's equipment was effective above the average. As the result of valuation on recreational value of forest road in urban forest, the recreational value was evaluated 153.2 won. So, if it is collected the using fees for forest road, it was showed that it is proper about 150 won for one person.

This study was carried out to investigate the distribution status and invasional characteristics of the naturalized plants. The vascular plants in these areas were consisted of total 381 taxa: 81 families, 234 genera, 295 species, 2 subspecies, 66 verieties, 18 forms. Among the investigated vascular plants, naturalized plants (Sicyos angulatus, Barbarea vulgaris, Thlaspi arvense, Amorpha fruticosa, Trifolium pratense, Ambrosia artemisiifolia, Ambrosia trifida, Aster pilosus, Rumex acetosella etc.) were 41 taxa. The Naturalization Index (NI) was 10.70% and the Urbanization Index (UI) was 15.30% at Chuncheon city. The Invasion Index was 63.41% at urban river and 97.56% at stream high, 19.51% at urban forest area.
