The purpose of this paper is to classify two study sites into the biotope types and investigate the landscape ecological characteristics of them. This will be available for the rural planning in the aspect of environmental preservation. The summaries of the result are as follows. 1) In the result of the area assessment in biotope groups, a dry field (32%) and a paddy field (28%) are more than 50%, but settlement space and water space are less than 10%. The result shows the land use condition of rural areas. 2) In the investigation result of elongation, running water spaces are higher than other biotope groups relatively, it is because they long shaped and 1-3m narrow. 3) In case of Fractal index analysis, residential spaces and cultivated lands are investigated to be lower in numerical value, it is because they have the definite borders and get simple in the border of landscape by human intervention. 4) In case of dispersion degree, the dry field has the highest value because they are located close by forests spread widely around study sites. It means that the land which is used by artificial purpose get more value rather than natural lands 5) In the connectivity analysis, a paddy field and a residential space appear the highest. It is because residence spaces spread intensively through roads and a paddy field, through streams. 6) In rural landscape, the diversity of landscape is investigated to be simple. A paddy field and a dry field contain small sized patches that have been divided by human intervention. Besides, there appear much different vegetation around waterways and farm-roads.

Journal of the Korea Society of Environmental Restoration Technology, volume 8, issue 2, 2005, Pages 21~32
Questionnaire survey from 101 visitors and 77 specialists was carried out to establish the management plan on landscapes of the artificial structure constructed in valley within Bughansan National Park. When comparison was made between ground sill work structure and valley landscape, visitor group responded to the highest scores in valley landscape after planting of vine species in the bottom of the constructure, while specialist group responded to valley landscape after the removal of the constructure. When it made a comparison between revetment work constructure and valley landscape, visitor group responded to highest scores in valley landscape after planting of vine species in the top of the constructure, while specialist group responded to valley landscape after replacing concrete revetment by stone revetment constructure. When it made a comparison between fall work constructure and valley landscape, both groups responded to the highest scores in valley landscape after the removal of the constructure. According to the valley landscape analysis, artificial constructures built in water channel should be matched to adjacent landscape with the removal of concrete constructure. The slope of water channel should be considered to build fall work constructure.

Park, Jong-Hwa ; Ryu, Kyong-Shik ;
Journal of the Korea Society of Environmental Restoration Technology, volume 8, issue 2, 2005, Pages 33~40
The objective of this research was to find an indirect method to estimate spectral reflectance and NDVI(Normalized Difference Vegetation Index) efficiently, using the spectroradiometer and NOAA AVHRR satellite data. For collecting RS base data, used spectro-radiometer that measures reflection characteristics between 300~1,100nm was used and measured the reflection of vegetation from paddy rice during the growing season at Chungbuk national university's farm in 2002. The feasibility of detecting the temporal variation in the spectral reflectance and NDVI in paddy rice were conducted on eight growth stages. AVHRR data were collected in eight different months over a one year period in 2002. The results were compared with those obtained by analyzing NDVI characteristics. The spectral reflectance and NDVI of paddy rice have a great effect on the growth condition. Considerably, NDVI was increased by developing muscle fiber tissue at the near infrared wavelength until the Booting stage. Then the NDVI increased until the Maturity stage and then decreased until harvest. The highest month was at July and the lower month was at March. The difference NDVI analysis using March and another months data was conducted, the results were provided information on the growth condition of crops.

In an effort to preserve biodiversity in increasingly fragmented green patches, Korea has been installing eco-corridors over or under some arterial or expressways. In a survey of 43 such eco-corridors installed up until the year 2003, some problems and issues were identified. Some selected overseas eco-corridors were also investigated to find implications for the improvements of future installations in Korea. Major findings are; - For most existing eco-corridors, target species are not specified and locations of the eco-corridors are not well considered, and consequently it is questionable if wildlifes are crossing them - Most of existing eco-corridors lack supporting facilities such as fences that guide wildlife to cross them and prevent them from running into the road - Planting on the eco-corridors is not sufficient, not diverse enough in species, and not very considerate of wildlife but designed and planted in a similar manner as in urban parks - Where target species are not well specified, the location, width, cross section, and other aspects of the eco-corridors can not be optimized - It is suggested that eco-corridors are planned at early stages of road planning so that the number and locations of eco-corridor(s) decided as necessary and even the alignment and design of roads consider the installation of eco-corridors in advance - Monitoring of wildlife crossings is needed for improved eco-corridor planning and design - Nationwide green network plan is desirable to be made first and eco-corridors fit into it.

The objective of this study is to provide basic data for building better exterior spaces for stadiums in the future by analyzing the behavior of users, such as the satisfaction measure and the physical environment, after using the exterior space at an existing stadium. To achieve this, multiple methods of data gathering and analyses such as field surveys, documentary surveys, and questionnaires research were used in this study. In the survey of user satisfaction, regression analysis was conducted on all factors. Factor analysis was conducted on the variables that were classified into physical, functional, social, and psychological factors. The factors were then tested and based on the results, multiple regression analysis was conducted to measure the effects of the factors concerning satisfaction. A questionnaire research on the use of the exterior space of a stadium as well as the social and economic backgrounds of the users was also conducted in order to utilize the results for the basic data for analysis of satisfaction. According to the results of this study, the exterior space of a stadium satisfied overall expectations. However, it is deemed important to introduce various facilities and activity programs and to improve the exterior spaces for users in building stadiums in the future.

A green area plan is getting attention as a way to solve the recent urban problems such as the rise of environment problems. To correspond to this change, there were dramatic amendments for the green area related laws. These amendments are appraised as the epochal turning point for the green area policies. This study is to introduce the main contents of amended urban green area law and urban park law in Japan, to compare with the Korean green area related laws, and to summarize the special features of both countries' green policies and the comments about the Korean green area policy structures. As a result, this amendment of Japan established the unified green area policy structure supporting the green area policies of municipal governments and is inducing living environment improvement by securing green area in the center of city, support, and the participation of residents. On the other hands, this amendment of Korea is a lack of the systemization of green area policy and the phased establishments of green area plan in spite of the scope of whole city because of absence of the unified high level plan.

The historical changes of seeding work in Japan, the typical slope revegetation method, is possible to divide into five periods as follows; 1) The early period after creation(1927-1948) 2) The spreading period of modern revegetation work with manpower(1947-1958) 3) The spreading period of rapid revegetation technique using exotic grasses with machineries(1959-1985
) 4) The spreading period of rapid reforestation technique by fast growing species mainly using leguminous shrub species(1986-1995
) 5)The developing period of nature restoration technique using endemic arborous species(1996-) The evaluation basis of vegetated condition after slope seeding has been described to a official guide book, "The Standards of Slope Stabilizing Works" It was mainly revised three times after first edition in 1972, and also the point of evaluation basis changed from the vegetation coverage to the density of woody plant through the 3rd period and the 4th period Recently main purpose of slope seeding has been developing from the erosion protection to the nature restoration in the current of the 5th period, and "The tentative guidelines of slope nature restoration" was announced by The Slope Revegetation Section of Japanese Society of Revegetation Technology in 2004. It was proposed the planning techniques of using suitable seeds/plants based on the preservation level at the real each construction sites Consequently, at present the importance of advanced monitoring methods for vegetation maintenance and plant sociologic survey to evaluate the plant succession is increasing.

This study aimed to address problems and suggest solutions in applying seed mixture design criterior of slope revegetation works according to the "Slope revegetation design and guidelines(proposed)" proposed by the Ministry of Construction and Transportation. To do this, a proper thickness of attaching soil media was identified in April experiment where the thickness and slopes varied. The results were as follows. In the test, the coverage rate of plot where exotic grass was not sowed increased with time and was 79.3% after three months of seeding, which indicated less risk of soil erosion. When applying the provisional standards of the plant mix proposed by the Ministry of Construction and Transportation, tree seeds and native plants were found ill in the early stage in all test lands due to exotic grass. This was because exotic grass which grew well in the early stage, could grow densely, so it might hamper the growth of other plants. When slope revegetation were planted and goals were set for herb, shrub and tree dominant mixture types, it was required to shift focus toward nursing up native plants first rather than early plantation of exotic grass.
