  • As the depletion of forests became more widespread due to the increase in the number of roads, the research was conducted on the relationship between temperature and humidity in the forests, assuming that the forests around the roads were affected. Through the forest monitoring, the temperature and humidity of coniferous forests and broadleaf forests in Sedong and Gongju areas were observed at three point of 10m, 20m and 30m from the road boundary to the inside of the forest, respectively. In Yeongdong area, for more reliable results, it was observed from the point of 0m, 10m, and 20m. During the study period, so it was expected the change in tree growth was small, the change of temperature and humidity inside the forest by the road was compared with the temperature and humidity from the road to the inside of the forest from September 2017 to January 2018, the changes of temperature and humidity inside the forest due to linear development such as roads were quantitatively analyzed. Using the HOBO data logger (MX2301, Onset Corp.), the temperature and humidity changes of each site were measured, and the average of the changes have been analyzed monthly. In the case of Gongju coniferous forests in September 2017, the average weekly temperature is $0.57^{\circ}C$ higher than the forest outside from the forest boundary and $1.23^{\circ}C$ higher than the inside of the forest, at night in November 2017, in Sedong broadleaf forests. That is, the ability to control the temperature and humidity of the forests along the road was larger and less variable as the distance from the road boundary to the inside of the forest increased. In this study, it is considered that the high degree of change in temperature and humidity of the forest and the surrounding area due to artificial linear development such as roads will affect the growth of trees. This results could serve as a basis for studying the quantitative scope of linear development affecting forest growth and for managing forest change caused by linear development.

  • The purpose of this study was to investigate the number of climbing plant species habitated in South Korea. Relationships between their distribution and environmental factors were surveyed. Research sites for vertical distribution were Mt.S rak, Mt.Kwangkyo, Mt. Eoudap and Mt. Chiri. The results of this study are as follows: The number of climbing plants habitated in South Korea was 267 species, 95 genera, 41 families. According as latitude lower, the number of climbing plant species increased. And most areas of Korean peninsula except for alpine regions and the northern part of North Korea seemed to be suited for the growth of climbing plants. The number of climbing plant species decreased with its altitude. And it is confirmed that their distributions were limited to the below of 1,500m sea level which was applicable to the area of Kira's warmth index above 45. The species of climbing plants changed with its plant community although at same altitude. The number of climbing plant species was different from the face of slope, and the species diversity became lower at south slope than that of north slope.

  • 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.

  • The rapid increase in the number of climate disasters combined with the scale of change and the diversification of natural disasters require a radical solution. In particular, the urban space is more complex, therefore we need to establish measures for disaster response and how to react to damaged infrastructure based on the phenomenon of an increase in the urban population and the impermeable layer being extended. The social problems related to the economic burden of land purchase and the securing of a disaster prevention system can be solved simultaneously by introducing the park system for disaster reduction into the public land of the green space in the city. The local government has recently adapted diverse systems of disaster mitigation and carried out pioneer projects according to the guidelines for the construction of the urban park for disaster prevention published by the Ministry of Land, Infrastructure and Transport. The purpose of this study is to propose a composition model for neighborhood parks to prevent disaster through urban green spaces which has the functions of water management and biotope conservation. The result of this study will contribute to utilize the climate change adaptation model for living area neighborhood parks in the existing urban structure.

  • We implemented ecological linkage assessment, through the connection components of the urban forests, rivers and parks, for the ecological connection of the urban parks which are standing out as the core of the urban green networks, so as to suggest basic data to compare, evaluate and improve urban green networks, as a basic study for the evaluation of the ecological connectabilities between the cities. For the ecological linkage assessment, we analyzed to see if the urban parks of Goyang, Ansan and Yongin, which are the subject cities, are actually ecologically connected with forests and rivers, using distance and roads, which are physical connection elements, in consideration of the mobility of the wild animals, and greening ratios and impervious pavement ratios, which are ecological connectabilities in consideration of the ecological values. The overall result of the ecological linkage assessment the physical connection elements and the ecological connection elements shows that the ecological green network ratio through direct connection states is 36.62% in Goyang, 42.55% in Ansan and 64.00% in Yongin, respectively, giving the ecological connectability ratio of less than half, with the average urban ecological green network ration of 47.72%. The comparison result of the ecological connectabilities between the object cities employing the connection elements indicates that when you set up green networks, you should consider together the physical connection elements, such as the roads, which will lower the ecological connectabilities - rather than do it simply based on areas and distances - while the ecological connection elements with the forests and the streams should be reinforced, so that the ecological connectabilities of the urban parks may be enhanced.

  • This study was conducted to analyze the planting structure and ecological characteristics of greon spaces on the grounds of e Dangjin steam power plant. To achieve these goals, we surveyed existing vegetation, plant community structure, Plant volume and growth rate. Based on e vegetation analysis, existing vegetation was classified into six types: herbaceous species $(70.54\%)$, evergreen coniferous trees $(21.17\%)$, deciduous broad-leaved trees $(5.10\%)$, deciduous coniferous trees $(1.47\%)$, shrubs $(0.12\%)$, and other types $(1.59\%)$. The coal storage, office, and playground areas were community is the natural forest area where a Pinus thunbergii / Pinus densiflora community is distributed in terms of vegetation structure, species diversity, plant volume, and growth rate. The artificial green spaces(near the coal storage, office, playground areas) had a single-layer structure. Species diversity indices of the artificial green areas were $0.1655\~0.4807$ compared to 0.8628 in the natural forest, which presented a good growth environment. Also, the plant volume in the artificial green space was lower than that of the natural green space. Therefore, it would be desirable to develope a multi-layer structure similar to that of the vegetation in the natural green space in order to improve the amount of plant volume. The plant-damage ratio of Pinus thunbergii was $52.48\%$ in the coal storage area, and $8.48\~ 11.52\%$, in the other survey areas. Also, the vitality of Pinus thunbergii was $15.45k{\Omega}$ in the coal storage areas, which indicates bad growing conditions. This suggests that soil characteristics and dust have a bad impact on growth. The investigation into deciduous tres' growth status showed that appropriate plants would be Albizzia julibrissin, Acer palmatum var. sanguineum, Acer palmatum, Malus spp., Prunus sargentii.

  • A outdoor space of the brand apartment can improve the quality of the whole environment in apartment and has differentiated identity in apartment housing through various versions of the green space and water space plan. The purpose of this study is to evaluate nature-friendly design characteristics in brand apartments and to offer a basic information for planning of brand apartment. In concrete, nature-friendly design did by green space and water space that can analyze by visual, and investigation contents divided to position, form, user behavior, link space from user viewpoint by case study. This study examined a case of eight brand apartments located in Gangnamgu, Seoul. We has divided the characteristics of a green space into horizontal type, vertical type, multi-dimensional type and has divided the water space into stagnant water type, flowing stream type, waterfall type and fountain type. The findings are summarized as follows: First, in case of the space of brand apartment, the application of horizontal and vertical greenery was lower compare with multi-dimensional green space. The most of items for multi-dimensional greenery have been planned to the open space and promenade. Second, a stagnant water type of water space features well used in most of the cases but a water space of signs of activity like a flowing stream, waterfall, fountain types were underused because of problem of administrative and maintenance expenses. Thirdly, Water space of brand apartments was planned with specialization item by apartment housing but green space does not have differentiated item and was planned by most similar form.

  • Problems in regard of ecological stability of urban ecosystem ensue from climate change and urbanization. Particularly, urban ecological conditions are deteriorating both quantitatively and qualitatively to a great extent. The present study aims to assess the current condition of selected sites (i. e. urban green zones and parks) in terms of preset assessment components; to find out problems and relevant solutions to improve the quality and quantity of parks and green zones; and ultimately to suggest some measures applicable to coping with climate change as well as to securing the ecological attributes of urban green zones and parks. According to the findings of this study, from quantitative perspectives, ecological attributes and responsiveness to climate change are high on account of the large natural-soil area(80%). By contrast, from qualitative perspectives including the planting structure (1 layer: 47%), the percentage of bush area(17%), the connectivity with surrounding green zones (independent types: 44%), the wind paths considered (5.6%), the tree species with high carbon absorption rates (20%), water cycles (17%), energy (8%) and carbon storage capacities(61%), ecological attributes and responsiveness to climate change were found very low. These findings suggest that the ecological values of urban parks and green zones should be improved in the future by conserving their original forms, securing natural-soil grounds and employing multi-layered planting structures and water bodies, and that responsiveness to climate change should be enhanced by planting tree species with high carbon storage capacities and obtaining detention ponds. In sum, robust efforts should be exerted in the initial planning stages, and sustained, to apply the methodology of green-zone development along with securing ecological attributes and responsiveness to climate change.
