Due to various environmental changes, the current location of the Gyeongsangbuk-do Agricultural Research & Extension Services needs to be changed to provide an appropriate environment and ecosystem for agricultural research and the efficient provision of public services. Accordingly, this study proposes a standard for selecting the new location. First, the location theory for the transfer of public facilities is investigated, and candidate filtration methods considered for the location selection. The candidate filtration methods include a component inspection, branch shape analysis, and mixed analysis. This study uses a component inspection, where the component criteria include the economic feasibility and ease of development, accessibility and convenience, agricultural conditions, soil conditions, connectivity, fairness, and human resource-richness of the region.

As Korean traditional peasant farming has come to a commercialization since 1970s, the spatial structure of Korean agriculture also has been gradually restructured by principle of not subsistance but economy. This epochal transformation of agriculture and its spatial structure in Korea are comparable with the first agricultural revolution in Europe. Facing this turning point, it is essential to redefine the nature and significance of agricultural geography in Korea through the review of the outcomes of about 200 studies published since 1950s in Korea of which twelve is concerned with locational analysis. The purpose of this study is to review the trend and characteristics of location studies on Korean agriculture. Major findings are as follows: (1) Since 1950s the location studies of agriculture recorded only 12 papers which occupy no more than 6% of studies of agricultural geography in Korea. This fewness suggests that the location study of agriculture in Korea is yet at the stage of beginning. (2) In spite of the fewness the studies, carried out mainly in 1980s, contributed considerably to clarify the locational characteristics of Korean agriculture especially in the spatial variations of crops, dairy farming and cropping system, the impacts of agricultural labors, the location strategy of mountain agriculture, and the responses of farmers to hazard. (3) In approach and methodology, two thirds of the studies has taken traditional empiricist view and other, positivist. And most studies adopted classic and neo-classic locational theories as their theoretical base in description and explanation. In degree of development, the location studies of agriculture in Korea seems to be about 20 years delayed compared to that of the advanced countries in terms of approach and methodology. (4) Such tradition of the location studies reflects not only the conservative nature of agricultural geography of Korea but also the early stage of capitalism of Korean agriculture.

This study was carried out to obtain the basic model to estimate damage degree from the correlation analysis between forest fire and site environment factors and to clarify the restoration trends thorough multi-temporal survey by observing species diversity followed by various treatments at damaged forest area over time. From the derived model, the damage degree of forest fire was higher in the area of dense coniferous stands composed of simple story at the elevation of about 100m and 200m, and on steeper slope area over 30 degree. As results of this study, fire damaged trees are needed to cut down and a mixed stand with deciduous and coniferous species from the same area is desirable for the future species composition on fire damaged forest. Thus, site characteristics, local species, and mixed stands are the main consideration to enhance the vegetation recovery.

The purpose of this study is to analyse the formation process and spatial structure of the mountainous village in the historic process as the case study on Yowon-village, Gyeongbuk province. The findings are summarized as the follows. The traditional location of the Yowon mountain village has been strongly influenced by local topology, drinking water, the form and time of the early setters. The spatial structure of the village was changed by the construction of road and accessibility to the road after the introduction of commercial agriculture. The form of the village consists of small scale of concentrated villages and dispersed. villages. Specifically, Yowon 1 ri has been restructured as a small scale of concentrated village and Yowon 2 ri as a dispersed one. The facilities both located in the center of the traditional village and related to communal life were moved outside while those for commercial agriculture were located in the center of the village. In sum, the village had been traditionally life-oriented and closed, but it was production-oriented and open particularly after the introduction of commercial agriculture.

This study attempts to analyze the spatial characteristics of organic agriculture in Korea during the period of 2000~2010, focusing on women's labor contribution to agricultural operations. Spatial distribution and concentration of organic farming have been investigated using Location Quotient(LQ) and Local Indicator of Spatial Association(LISA), it was found that the specialized organic farmland in the Seoul Metropolitan area has decreased significantly over the past decade, while in Chungnam and Kyungpook province it has been rapid growth in the same period. Multilinear regression analysis was also carried out to find out whether the spatial clusters in organic farming depends on women farmers. Results describing the correlation between organic farming and women farmers within identified clusters suggest that the possibility of the transition towards sustainable agriculture and farmland restructuring in Korea, by women.

This study aims to indicate the spatial characteristics of the changes in the Korean farm land. In particular, we analyze the spatial diffusion patterns of organic farms increasing rapidly with the growth in the agricultural product markets as well as the demand for safe food and sustainable growth. For the purpose, we examine the changes in the distribution patterns of organic farms between year 2000 and 2005. We analyze the agglomeration pattern by Location Quotient (LQ) and Local indicator of spatial association (LISA). Organic farms have been spread out from the outscuirts of Seoul, the capital city, to the traditional agriculture spetilized area in the southern parts of the nation. In order to analyze the relationships between organic farm distribution and the geographical variables affecting the organic farming, we develop multivariate regression models. Our findings indicate that organic farming is related with the number of agriculture-based business and information technique adaptation as well as the level of education and farmers age.

This study aims at explaining locality of living space which is changing drastically by exploring change of land utilization, living space and condition in Yeo-ju, an agricultural area around Seoul. The conclusions are as follows. 1. Agricultural land utilization tends to decrease, while civic land utilization tends to increase. 2. Change of living space due to transportation development is remarkable. Big ferry town (Yeoju-town) grew to a city, while small ferry town fell away. 3. In villages on slow urbanization, houses or lands are deserted. 4. In villages, there has been increasing number of recreational farm for urbanite. 5. In 80% of villages, there has been an increasing number of part-time farmers. 6. Most serious social problem in Yeo-ju is incompetence in agricultural activity after UR. In sum, Yeoju is now an area where the pace of urbanization is very tardy. However, this area, as an changeable area just before speedy urbanization, is expected to be urbanized drastically on condition that transportation develop. When plans suitable for this town are set up, Yeoju is expected to be a comfortable city.

BACKGROUND: Ecological functions of irrigation ponds were well known fact that important for biodiversity conservation in agricultural ecosystems. However, many irrigation ponds were destructed with changes of agricultural environment. The objective of this study is to appreciate the importance of ecological functions of irrigation pond. Furthermore, it presented to useful information for restorations of irrigation pond from analyses of correlations between benthic macroinvertebrate communities and locational factors of irrigation ponds. METHODS AND RESULTS: Benthic macroinvertebrate sampling was conducted from 2010 to 2012 at 15 study ponds. Comparisons of benthic macroinvertebrates diversity approached species richness and density, and statistical analyses were performed using independent t-test. A total of 131 species / 137,118 individuals of benthic macroinvertebrates were recorded during study period. Dominant taxa of benthic macroinvertebrates included Coleoptera, Hemiptera, and Odonata. Generally, benthic macroinvertebrate diversity in mountain region and existing ponds were showed higher than open field and created ponds, respectively. DCA ordination showed that benthic macroinvertebrate community was most correlated with locational characteristics of irrigation pond, and it correlated with bank type and age of pond. CONCLUSION(S): In conclusions, in order to restore ecological irrigation pond, it is necessary to consider environmental factors such as locational characteristics and bank types.

특용작물 선택은 자기지역의 입지조건에 알맞은 작물과 품종을 선정하여 농업경영을 합리적으로 다양화 할 필요가 있다. 우리나라는 다행히 기상변화가 뚜렷하고 작물의 종류도 대단히 많은 실정이므로 지역별 주산단지를 조성하여 생활필수품 또는 중요한 가공원료로서 용도를 가지고 있는 작목과 우리나라 고유의 특산품으로 각광을 받는 작물을 선택하여 재배함으로서 앞으로 다가올 올림픽용품 등을 제조 판매하거나 수출하여 외화를 획득할 수 있는 좋은 기회라고 생각된다. 그러므로 특용작물을 도입하여 농업경영을 합리화하려면 적지적작(適地適作)의 원칙에 따라 그 지방의 기후와 토지조건에 알맞은 종류와 품종을 선택하여 재배 기술과 수확, 조제, 가공방법 등을 잘 파악하여 재배하도록 한다.

To investigate effects of fanning practice and $NO_3-N$ contents of groundwater in intensive horticultural greenhouse area of Yeongnam province, the groundwater samples from 1,370 sites were collected and analyzed. In addition, cultivation year, crops, desalinization methods, amounts of manure application, tube well depth and soil texture with clay contents were observed. Of the investigated sites, 19.7% of shallow groundwater and 1.3% of confined groundwater were exceeded over $10mg/{\ell}$ as the $NO_3-N$ drinking limit value, respectively. $NO_3-N$ concentration in groundwater was highly significantly correlative with clay content $(r=-0.241^{**})$, well depth $(r=-0.228^{**})$ and cultivation duration $(r=0.104^*)$, respectively. In case of desalting crop method being executed for desalinization of greenhouse soil, the $NO_3-N$ value of groundwater was lower than any other desalinization method. The fact that $NO_3-N$ contents of confined groundwater was affected by shallow groundwater was clarified by that $NO_3-N$ contents in shallow were significantly correlative with the confined groundwater $(r=0.532^{**})$.
