A variety of revegetation methods are being utilized and developed. However, most of revegetation methods used on highway slopes in Korea are based on foreign-introduced plant varieties to stabilize road surfaces and to administer afforestation for surface covering at an earlier phase. Therefore. it results in various problems. such as failure to achieve harmony with the surrounding vegetation and 10 cause re-denudation of slopes as the foreign-in introduced plant varieties wane out from 2~3 years after hydro-seeding, etc. In addition, some of the revegetation plants seeded in the earlier phase grow excessively high, thus causes successional problems, such as to inhibit the invasion of the secondary vegetation from the surrounding areas, etc. Therefore, in this study, 160 slopes located in the nationwide express highways have been investigated and analyzed in order to produce basic data for restoration of ecological environment in slopes created on a long-term basis by investigating and analyzing locational characteristics of cut and filled slopes in express highways, status of revegetation methods, characteristics of soil and plant-ecological environment. 1. Investigation on cut and embanked slopes in express highways was carried out in the total of 160 locations, which include 108 cut slopes and 52 embanked slopes. As a whole, the most frequently used revegetation method was seed spray, which was found to be used in the total of 55 target slops investigated. 2. Planting method of Wistaria floribunda applied to some of the blasted rock zones was found to cause damages as Wistaria floribunda trailed up the surrounding vegetation and the secondary invaded trees. In order to prevent this, this method must be used only in the lowest parts of large-sized slopes. Also, it will be required to administer continuous management and maintenance in the areas already planted with this plants. 3. The areas of blasted rock and ripping rock slopes were applied with coir net (net + seeding) method. However, many of these areas failed in achieving ground covering. Most areas where revegetation was in progress, they were covered with Eragrostis curvula(Weeping lovegrass) only. In areas with soil, such as decomposition of granite, where afforestation is difficult. In this slopes, soil base must be improved by hrdroseeding with thin-layer vegetation base application methods in order to achieve success in afforestation with native plants. 4. Woody species, rather than herb species, are more helpful in stabilization of slope surfaces. Therefore, it is important to be able to grow and protect woody species on highway slopes. Growth of woody vegetation is most largely influenced by soil depth. Thus, when hydro-seeding woody plants, it is recommended to apply at the upper layer of the slopes, which is capable to sufficiently provide the fundamentals required in plant growth.

The purpose of the study is to analyse and classify the characteristics of Gongsanseong forest through phytosociological and quadrat method with 20 plot samples. In result, the forest was classified as Quercus acutissima community. The subcommunity was composed of Quercus aliena and Zelkova serrata. The average vegetation coverage of Quercus aliena subcommunity was upper tree layer (83%), lower tree layer (48%), shrub layer (39%), and herb layer (30%), while the average vegetation coverage of Zelkova serrata subcommunity was upper tree layer (76%), lower tree layer (52%), shrub layer (40%), and herb layer (45%). The order of importance value of the forest community with DBH 2cm above plants was Quercus acutissima (72.62), Quercus aliena (40.52), Prunus sargentii (19.81), Styrax japonica (19.39), Zelkova serrata (15.78), Robonia pseudoacacia (14.76), Quercus variabilis (13.83), Sorbus alnifolia (13.71), Platycarya strobilacea (10.74), Pinus densiflora (10.08), and Quercus serrata (9.31). According to breast diameter analysis results, it is expected that the importance value of Prunus sargentii and Zelkova serrata will be continuously increased while Quercus sp. is dominating the forest. With the result of ordination analysis, the relationship between the forest community and environmental factors could be affected by soil nutrition, moisture, and elevation etc.

Journal of the Korea Society of Environmental Restoration Technology, volume 10, issue 2, 2007, Pages 26~33
This study was to investigate the reaction analysis of citizen on fence removal for securing green space. The results are as following; The majority of users went to green space more than one time per week to take a walk, rest and stayed there less than an hour. The places, where the fence removal was required mostly, were public institutions, parks and schools. The physical factor was the highest influence on whether the fence removal project could be expanded or not. With a slight difference from the physical factor, the environmental and emotional factor followed after. The social factor was also significant at 1 % level. In the physical aspect, the increase of garbage littering was the most negative part after fence removal.When the citizens were asked if they would participate in the fence removal project, the environmental and emotional factor and the social factor were the most influential ones on work places while the environmental and emotional factor influenced only on private houses.

Journal of the Korea Society of Environmental Restoration Technology, volume 10, issue 2, 2007, Pages 34~43
To investigate the restoration procedure on soil physical properties and vegetation at the surface of strip road affected by timber harvesting operation. This study was carried out at strip roads constructed between 1989 and 1994 in Mt. Baekun, Kwangyang, Chollanam-Do. Soil hardness of the surface layer was improved with change of time after strip road construction, but that of 7.6~15 cm depth from the surface was not improved. According to linear regression analysis, it was estimated 16.6 years in 0~7.5 cm and 16.9 years in 7.6~15 cm soil depth to be restored to natural forest lands. The amount of surface soil erosion was 0.045
/km/yr on strip roads constructed in 1989 and 1990, and road constructed in 1994 showed the highest value (4.5
/km/yr). Vegetation coverage rates of road surface were 96.7% in strip roads constructed in 1990. Those of cutslope and fillslope were highest in roads constructed in 1990. The results indicated that strip roads were restored with change of time after road construction.

Journal of the Korea Society of Environmental Restoration Technology, volume 10, issue 2, 2007, Pages 61~70
This study aims to clarify the effect of forest management practices(thinning and pruning) on soil physical properties and water quality to get the fundamental information on the facility of purifying water quality after forestry practices. Rainfall, throughfall, stemflow, soil and stream water were sampled at the study site which consists of Pinus rigida in Jinju National University Experimental Forest for 4 years from Mar. 1, 2002 to Nov. 30, 2006. Averaged tree height of the management site increased by 1.6m, compared to the value of the non-management site in Pinus rigida. Increment of averaged D. B. H. at the management site showed 4.2cm more in Pinus rigida compared with that at non-management sites. Mesopore ratios (pF2.7) and total porosities of A layer soil at the management site increased more than those at the non-management sites in both stands. Otherwise, soil bulk density resulted in being reversely. Water qualities of throughfall, stemflow and buffered soil water were influenced more positively by the management practice. The average electrical conductivity of stream water was
within the range of non-polluted stream water.

Journal of the Korea Society of Environmental Restoration Technology, volume 10, issue 2, 2007, Pages 71~83
This study aims to provide basic data for planning the supply and demand of urban parks and setting up facilities in urban parks that reflect the use patterns of visitors. The study was conducted by surveying the total number of urban park users and the number of users for different time zones and analyzing their use patterns through on-site surveys at 17 urban parks located in seven cities/counties in Gyeonggi province. The result showed that as for distribution of urban park users by time zone, the number of users was highest in the afternoon. Between 7 and 9 o'clock in the morning in weekdays, many users came to urban parks for their morning exercises. There was hardly no difference between male and female. When the number of users of 17 urban parks was surveyed, a park was used by 734 people per day on weekdays in average. When the total number of users per year was estimated, a resident nearby a park visited the place 4.7 times a year in average. In addition, the analysis showed that the number of users of man-made parks was twice as high as that of natural parks. The number of users did not vary depending on the size of a park. As for use patterns by time zone, no difference was found in activity types between parks larger than 100,000
and those less than 100,000
. Usually, in the morning, users came for exercises In the afternoon, users visited the parks for more diverse purposes. In the evening, they tended to visit parks to work out and wrap up a day. Going forward, the outcome of this study should be utilized as important data for analyzing the demand and supply of urban parks. In addition, the number of users by time zone and their use patterns should be fully considered when introducing facilities in parks.

The purpose of this study was to select herbaceous plants that can be used for presenting various views and biodiversity on the extensive rooftop greening. Experiment plots were constructed in July 2005 on the rooftop of the Administration Building in the Seoul Women's University. For this experiment, planters were used to design rooftop greening. The size of a planter is 500mm
100mm and each planter has the water storage plate in the lower part of it. The soil was constructed by mixing pearlite, vermiculite, cocopeat, and leaf mold in the ratio of 6 : 2 : 1 : 1. The plot was divided into the watered plot and the dry plot. Since each plot was constructed 2 times, finally 4 planters were constructed in total. One hundred species were used for the experiment and 9 plants per species were planted in each planter. Plants were organized according to types of plants and the experiment used 86 native herbaceous plants, 6 herbs, and 8 foreign plants. The plots were monitored once a month, from July to November 2005. The length and width of plants were tape-measured and covering rate was calculated by CAD program. "SPSS 10.1" was used for a statistical analysis. The result showed no significant difference between the watered plots and the dry plots. In cases of some plants, there were statistically significant differences between the watered planter and dry planter such as follows : Astilbe chinensis and Polygonatum odoratum which are shade plants were measured as the highest value on the watered pots, and Aquilegia buergeriana, Chrysanthemum zawadskii, Calendula arvensis and Gypsophila cerastioides D.Don which are sunny plants were measured as the highest value on the dry plots. According to the final analysis of the data collected and observed for growth condition during the first year of the research, 51 species including Prunella vulgaris var. lilacina and Veronica linaiaefolia in native herbaceous plant, 5 species with Lavandula angustifolia in herbs, and 3 species with Lantana camara and Muscari armeniacum in foreign plants showed the highest growth condition. In conclusion, it is suggested that various plants including sedums could be effectively used for extensive rooftop greening to improve landscape(a view) of the rooftop and increase ecological values.

A/R CDM(Afforestation/Reforestation Clean Development Mechanism) in Kyoto Mechanism means, either afforestation in the area used for other purposes more than 50 years or reforestation in the area used for other purposes on December 31st in 1989. South Korea has few sites due to the successful forestation in the past, but North Korea has not reforested the deforested lands since the mid-1970's. So these areas need to apply A/R CDM Project for restoration. The purposes of this study are to make a time series analysis in deforested areas and to estimate a feasibility of A/R CDM. To find the site satisfying A/R CDM business definition, land cover classification was applied using satellite images of the mid-1970's with good forestation, late 1980's including A/R CDM base year, and recent 2000's, and the chronological change was analyzed to categorize the possible sites. The North Korean topographical map of 1977 was used to verify land cover classification degree of 1970's, the land cover classification results made by the Ministry of Environment in 2000 were compared to verify the accuracy of 1980's results, and the land cover classification results in 2000's were verified by 2 site visits. The results of this study can be summarized as follows. The eligible A/R CDM sites are 605,156ha on the basis of the forestation change analysis in North Korea. Since the mid-1970's, 30.8% of the decreased forestation area of 1,966,306ha was classified into A/R CDM eligible sites. While other countries have the limited eligible sites, which has not been used for forestation since 1989 or which is being scattered, North Korea has large scale sites. Deforested sites are mainly around road and residential area, consequently give better accessibility for forestation than other countries. In conclusion, it is found that North Korea can provide efficient site for applying A/R COM Project to forestation restoring deforested land because of easy accessibility and existence of many possible sites due to artificial deforestation. Also, it is meaningful that the study suggests the application possibility of A/R COM Project to restore deforested land in North Korea and the related basic information through the chronological classification of the mid-1970's with good forestation, the late-1980's including A/R COM base year, and recent 2000's. It is expected that the study contributes to revitalization of A/R CDM Project and related research on North Korea forestation.

Journal of the Korea Society of Environmental Restoration Technology, volume 10, issue 2, 2007, Pages 105~119
Numerous developments have damaged agricultural landscapes and consequently agricultural areas have lost the amenity and their traditional culture. Despite the fact that damaged agricultural landscape is irreversible, precautionary policies for conserving agricultural landscapes in Korea have not been established properly. Meanwhile, social demands for well preserved rural landscapes have increased. This study, thus, aims to evaluates esthetic values of agricultural landscapes in order to prepare the basis for the formulation of properly informed policies. Bearing in mind the purpose of the study, firstly, present status of agricultural landscapes has been surveyed. Secondly, agricultural landscape values were estimated in friendliness, ruralness, and preference with 30 selected slides and 4 computer simulated pictures out of 305 pictures. The survey has been carried out with two student's groups of the landscape architecture majored (50 people) and the ordinary majored (68). The results implicated that agricultural landscape preferences has not been changed for 10 years to some extent. However, landscape majored respondents showed low preferences on the artificial creatures than the non-majored. Lastly, Recommendations for the agricultural landscape policy was made that the necessary developments should be considers form, colour, location, and size according to the natural landscape.
