In this study, I have summarized the geographical location conditions according to geographical position where communities locate and I have classified the spatial composition factors into size factor and the line factor. This was accomplished through field research and comparison and analysis of pertinent literature. Then, I have discussed the geographical location conditions and the characteristics of the spatial composition of a particular community. Finally, I have pointed out that the similarities and dissimilarities of the spatial composition factors of a certain community with locational aspects, geographical aspects, and occupational aspects, can be considered.

This study aims to interpret the location of 4 traditional settlements in the Youngnam district of Korea in view of geomorphology. For this study, GIS techniques were used to analyse quantitatively the degree of slope, slope aspect and the relation with river/stream of these regions. Yugok is located on pediment in the valley basin. Cheonjeon is located in the end part of the hill. Hahoe is located on the convex natural levee of the flood plain. Yangdong is located on a hillside. Houses are mostly distributed with south, southeast, and southwest aspect, but in Hahoe face all sides. Also, the settlements are located on average $10{\sim}20m$ above river bed. This indicates a safe height above river bed for avoiding an flood damage. These results imply that the location of the traditional settlement is based on a scientific logic and rationale. It is thus argued that the settlements satisfy exellent geomorphic conditions from the perspective of modern theories of residential location.

The study was carried out to provide information about growth and ecological characteristics by site types of natural deciduous forest in Pyeongchang, Gangwon Province. The data were collected from four aspects(the East, the West, the South, and the North) with three elevation(higher than 1.000 m, 700~1,000 m, lower than 700 m) and three topographical conditions(ridge, hill, and valley). Growth parameters by site types were evaluated based on the growth performances of dbh for the last 5 to 10 years; which were also estimated based on both Pressler and Schneider formulae. In addition, ecological characteristics such as Shannon-Wiener's diversity index, evenness index and richness index were analyzed by site types. The management methods by site types were suggested by considering stand density, growth patterns, and ecological characteristics. It was found that the stands on the South and the East are necessary the tending practices to improve growth and ecological characteristics. On the other hand, the West and the North needed the tending practices focusing on stand density management to increase growth rate rather than ecological management. It was also found that the area lower than 700 m in elevation showed Higher growth rate than other areas. As a management standard considered in terms of growth rate, it was suggested that tending practices should be applied to the stands of which growth rate for the last 5 to 10 years were lower than 2%. Considering topographical conditions, valley area showed better ecological characteristics than both ridge and hilly areas. Consequently, it was revealed that the valley areas were suitable for the ecological management.

Place names represent a lot of information about the region and the life of the local residents. In particular, old geographical names have more spatial informations than recent place names. This paper tried to analyze the distribution and characteristic of 'Dumo' which is one of the ancient place names and was studied by Nam youngwoo in 1996 for the first time. After considering the etymology and phonological structure of 'Dumo', the name 'Dumo' included the geographic conditions related to a mountain and river in itself. The total number of place names in the line of 'Dumo' which were collected by the author were 417 and they were distributed evenly on the Korean Peninsula. 85% of them were used for the human place names and 73% of the human place names were served as settlement names standing for a village or an administrative district. Thus the author analyzed the location and diffusion of 220 of settlement names in depth. As a result, villages named in the line of 'Dumo' preferred southern or eastern exposure and located in front of a mountain and around a river. After a village name 'Dumo' was set up, it produces other similar names in the line of 'Dumo' near the village so most place names of 'Dumo' were found with several names of 'Dumo' not alone.

In this study we investigated the effects of the microclimatic conditions on tree growth in different site types for natural deciduous forests in Korea. First, we classified all the sites into 36 types according to their aspect (east, west, south, and north), elevation (higher than 1,000 m, 700$\sim$1,000 m, and lower than 700 m), and topographical conditions (ridge, slope, and valley). For each site type, we measured diameter growth with increment borer, and then estimated periodic annual increment of diameter, height and volume. We applied a topoclimatological technique for estimating microclimatic conditions, and produced monthly climatic estimates from which 17 weather variables (including indices of warmth, coldness, and aridity) were computed for each site type. The periodic annual increments of diameter, height, and volume were then correlated by regression analysis with those weather variables to examine effects of microclimate on tree growth by site type. We found that the correlation of diameter growth by site type was significantly correlated with most weather variables except daily photoperiod. Water condition was the most important factor for the height growth. For volume growth, on the other hand, the conditions such as relatively high temperature and low humidity provided favorable environment. Our regression analysis shows that aridity index is a good predictor for tree growth including diameter, height and volume increments.

This study was conducted to estimate microclimate of natural deciduous forest in national forest of Pyungchang, Kangwon province and to investigate the effects of the microclimatic conditions on the periodic annual increment of diameter by site types. In this study, site was first classified by nine types considering both elevation (higher than 1,000 m, 700∼1,000 m, and lower than 700 m) and topographical conditions (ridge, slope and valley). For each of site types, diameter growth was measured by using increment borer and periodic annual increment of diameter was then analyzed. A topoclimatological technique, for estimating microclimatic conditions, which make use of empirical relationships between the topographical factor and the climatic normals in the study area was applied to produce monthly mean, maximum and minimum temperatures, relative humidity, precipitation and hours of sunshine. From these monthly estimtes, 17 weather variables such as warmth index, coldness index, index of aridity etc. which affect the diameter growth were computed for each of site types. The periodic annual increment of diameter was then correlated with and regressed on the 17 weather variables to examine effects of microclimatic conditions on the diameter growth by site types. From the correlation analysis, it was found that the diameter growth by site types was positively correlated with all of 17 weather variables except the warmth index. Especially, the conditions such as high relative humidity and large amount of sunshine hours provide favorable environment for the growth of diameter. On the other hand, it was also found that diameter growth was negatively iufluenced by warmth index. According to the regression analysis, the periodic annual increment of diameter could be well predicted by index of aridity and mean relative humidity for the growing season.

As marine desertification and chlorosis in Korean coast have been intensified over time, Korean government is promoting marine afforestation projects. However, marine afforestation location is mainly decided by administrative convenience. Also, there is limited literature on location suitability about the marine afforestation. This study aims to assess location suitability of marine afforestation considering 3 significant criteria: ecological, submarine topographical, and human-social environment. Jeju, the study area of this study, first observed chlorosis in Korean coast at the small fishery town in Seogwipo. Jeju is currently suffering from chlorosis all around the island. Habitat Evaluation Procedure (HEP), 3D kriging, Analytic Hierarchy Process (AHP) is applied as analysis methods. Especially, 3D kriging is utilized for modeling 3D ocean space reflecting ocean environment appropriately. The result shows that Jocheon coast has better location suitability than Seogwipo Pyoseon coast. Jocheon coast has the maximum 61% suitability as the habitat of Ecklonia cava Kjellman, and is highly evaluated in other criteria. The results of this study are expected to find optimal marine afforestation location, and to contribute to the restoration of the Jeju coastal ecosystem and the revitalization of Jeju fishing village societies.
