This study was executed to measure the user\`s impact natural environment in National Park Campsite. Therefore, we choose Mt. Chiak National Park and the campsite in the district of Temple Ku-Ryong as a model of analysis, which is made by ecological approach, the number of the user has influence on the environment near the campsite. The result are as follows : 1. The more the number of users becomes, the more Na, Ca, Mg ion concentration and pH in the soil increase and the less K ion becomes. 2. Litter and humus depth, litter coverage, herb coverage, soil hardness, the surface of the ground layer and tree species numbers, density and coverage of lower layer shows a sensitive reaction to the number of the users. 3. The research shows that the tolerant trees against campsite impact are Lespedeza maximowiczii, Zanthoxylum schinifolium Staphylea bumalda, Smilax sieboldii, Quercus aliena, Euonymus oxyphyllus, Weigela subsessilis and Securinega suffruticosa, and the sensitive trees are Stephanandra incisa, Rubus trichocarpa, Rubus crataegifolius, Rhododendron mucronulatum, Styrax obassia, Acer palmatum, Lindera obtusiloba, Rhododendron suhlippenbachii, Rhus japonica and Callicarpa japonica. 4. The high density of the users made the simplication of a vegetation structure. So, as the number of the user increase the species showed severe heterogeniety between the heavy-use and nonuse site. 5. As considering the landscape management about campsite and surrounding area on the way of analysis of national landscape aspect and succession sere according to ecological aspect, it may be desirable that Pinus densiflora forest be conserved as Pinus densiflora landscape and mixed forest produce natural scenery with succession sere.

The methods of landuse change detection have been used with the algorithm of GIS (Geographic Information System). It is used for the Environmental Planning. Ultimately, it is useful to establish environment management system in landscape architecture. As one of environmental elements, the landuse is repeatedly being changed by the interaction of natural and social environments. In addition, the landuse change shows a tendency to certain characteristic. However, the data of analysis environment system are too broad to access the practical use. Therefore, the possibility of using the method of GIS has been increasing. This study is to make the prediction model by using the interpolation of GRASS version 4.1.5 and to consider about a tendency for each element in landuse change of HAKONE national park. The results of study explain as below : 1. The natural forest and the meadow have a larger tendency of decrease. 2. The area of golf club and facility land has not been changed and the some other areas have been changed to the commercial forest. 3. However, because of the natural forest preservation plan since 1970, the destruction shows comprehensively a tendency of decrease.

The main purpose of this study was to estimate a new regression model to explain the relationship between urban forest and air temperature in summer, 2001. This study consists of two parts: correlation coefficient analysis and regression analysis. According to correlation coefficient analysis, thermal infra-red radiations of the major land use categories found significant difference in each category. However there were no significant relationship between the data (thermal infra-red radiation and NDVI) derived from Landsat-7 ETM+ image and air temperature at Automatic Weather Stations(AWSs). After estimating various regression models for summer air temperature, the final models were chosen. The final regression models consisted of two variables such as forest m and traffic facilities area. The regression models explained over 78% of the variability in air temperatures. The regression models with variables of forest area and traffic facilities area showed that the coefficient of the first variable was even more significant than the second one. However, the negative impact of the traffic facilities area was slightly greater than the positive impact of the forest area. Consequently, the effects of forest area and traffic facilities area were apparent to explain summer air temperature in Seoul. Therefore two policies have the most important implications to mitigate the summer air temperature in Seoul: to expand and to conserve the urban forest; and to change the Oafnc facilities'characteristics. The results from this study are expected to be useful not merely in informing the public that urban forest mitigates summer air temperahne, but in urging the necessity of budgets for trees and managing urban forests. It is recommended that field swey of summer air temperature be Performed for the vadidation of the models.

Estimating the habitat potential of inland forest patches for birds requires the modeling of species-area relationships, or relationships between habitat size and numbers of bird species in each patch. The accurate estimation of speciesarea relationships significantly reduces the effort required to recognize the number of species living in each patch. The objective of this study was to estimate the relationship between forest patch size and bird species diversity in Dangjin County, in northwest South Korea, based on the sizes of inland forest patches. KOMPSAT-2 images were obtained and ortho-rectified to construct a map of the target forest patches. The numbers of birds per patch were surveyed four times: August 2008, September 2008, February 2009 and May 2009. Regression models were derived to explain the relationships between the numbers of bird species and patch size. A model that was derived using data from all four observation periods had the highest coefficient of determination ($R^2$). According to these models, the numbers of bird species at first increased linearly with increasing patch size; however, the curve then plateaued. Our model including observations from four seasons will be useful for estimating the numbers of bird species in other inland forest patches in South Korea.

Factors for promoting the resident participation in mountain villages are suggested to introduce the activity-oriented program of green tourism using a multinomial logit model(MNLM). Direct surveying, using a structured questionnaire was performed on local residents in the different types of rural tourism villages such as mountain villages, agricultural themed villages, and the mixed types of villages. The MNLM revealed that participation intention in the program was significantly higher for males, those with lower education, and residents in mountain villages. The participation intention of the program had a negative relationship with the increase of expected problems not from the program itself, but from the results of the program such as income distribution and nature destruction. Participation intention also increased with the indirect effects of an investment by the Village Development Project, such as local cooperativeness, public mind, etc. It was suggested that to introduce the activity-oriented program in mountain villages, negative effects from the results had to be minimized, and positive effects from the indirect changes between local residents had to be maximized through better communication and policy endeavors.
