  • The Purpose of this study is to predict farm size per farming household in Chungcheongnam-province by using the Markov chains and Quadratic Programming.. The results are as follows; First, small-scale farms with less than 1.0ha of land are predicted to be still more than half (of total farming households) in 2025 as well. Second, large-scale farms with 3.0ha-5.0ha land and extra large-scale farms with over 5.0ha of land are predicted to gradually expand their proportion in total farm scale. Third, middle-scale farms with 1.0ha-3.0ha land are forecasted to be reduced in their relative proportion. It is required to take into account regional characteristics to improve the effectiveness of a rice industry policy. Therefore, this study has some significance in attempting to research on the ownership structure of rice production areas in consideration of target regions.

  • 경남 및 전남지방은 산업에 있어서 농업의 비중이 상대적으로 큰 지역이다. 두 지방의 농업의 특성은 큰 차이는 없으나, 전남 지역이 농가인구, 호당 경지면적이 넓다. 영농 형태별로는 전남 지역이 수도, 전작의 비중이 크며, 경남지역은 과수, 채소, 화훼, 축산 등 소득작목의 비중이 높다. 농업기반에 대하여 보면, 농업진흥 지역비율은 경남 53.7%, 전남 64.8%이며 수리답율은 81.9% 76.1%, 경지정리율은 76.1%, 68.4%로 경남지역이 유리한 기반을 갖고 있다. 작목별 특화도를 보면 경남 지역은 맥류, 서류, 앙파, 마늘, 감, 화훼류 등이 높으며, 전남 지역은 맥류,두류, 마늘, 양파, 감, 참깨 등이 높게 나타나고 있다. 지역내 수급현황을 보면 경남지역은 미곡, 두류, 무, 배추, 고추, 사과, 포도, 복숭아 등이 부족하며, 서류, 마늘, 양파, 배 등이 과잉이고, 전남지역은 대부분이 과잉이며 사과, 포도, 복숭아 등이 부족하다. 지역간 농업협력은 상호 과부족인 농산물의 교역이나 비교우위가 있는 작목에 특화함으로써 서로 이익을 누리는 방안과 타 지역이나 해외 진출에 있어서 공동보조를 취하는 것으로 생각할 수 있다. 이에 대한 구체적 빙안으로서는 무엇보다 양 지역농업 및 농민에 대한 상호 이해가 이뤄져야 하며, 이를 전제로, 지역별 비교우위가 분명한 품목에 대하여 상호 우선적으로 구매할 수 있도록 하는 등 상호 교역을 지원하며, 농산물 수급 불균형으로 인한 가격파동을 예방하기 위하여 계획생산, 계획 유통이 불가피한 만큼 농협, 농민단체, 지방정부간의 농업정보의 공유와 조정 채널을 구축하고, 지역간 직거래 활성화하고 서로의 이해를 돕기 위한 농산물 장터 등 장소와 기회를 제공하며, 해외수출 시장 개척을 위한 공동 노력, 농업기술의 상호 교류 등이 필요하다.

  • This study aims to make a "farmland use map" using high-resolution images and to analyze the land use change for about 8 years in Goyang, Namyangju, and Yongin cities. We have made a new numerical map named as a farmland use map using high-resolution images taken mostly in 2007 and digital topographical maps in Goyang, Namyangju, and Yongin cities near metropolitan areas to classify farmland use of paddy, upland, plastic film house, and orchard. We also made a land use map by overlaying the farmland use map and the land registration map of each city made in 2007, and compared the land use map made by RDA (Rural Development Administration) in 1999. Paddy areas decreased at a range of 3,000 to 5,000 ha during 8 years and were changed to residential areas in the cities. Upland and orchard areas also showed similar tendency and were changed to residential areas as well. On the other hand, the areas of the plastic film houses in the cities showed an increase or same in size. It is suggested that farmland use map can be broadly used as a base map for various survey projects including soil survey, statistics, and farmland information management.

  • Long time ago, Korea region based on the agriculture society has been changed in terms of a variety of factors, differently a metropolis. Specially the region located nearby urban area generates a number of variations by the environmental, economic and social factors, these variations have appeared with the similar characteristics in other areas. On that score, if we classify variation factors by means of analyzing quantitative or assign the standards or weights to apply as a agent concept, will anticipate mote accurate information of the land-use ratio, squares related of agriculture region in the future. In this study, we estimated applicable possibilities and extract the variation factor between annual surveying images and real values which estimated local products, variation factors related of attributes through Landsat images of Korea for the 5 years.

  • 산업의 발전과 더불어 농업인구는 해마다 감소하고 있으며 농업 연령층은 고령화 현상이 나타나고 있다. 전체 농가인구와 호당 농업인구가 줄어들고 있는데 반해 호당 경지면적은 매년 증가하고 있다. 노동력은 농업생산비의 가장 큰 비중을 차지하고 있고, 농가의 연령층 또한 고령화가 되어가고 있음을 고려해 본다면 농업의 기계화ㆍ자동화의 필요는 절대적이다. 수확은 재배 과정 가운데 노동력, 시간 및 비용이 가장 많이 소요되는 작업이다. 본 연구는 수확용 매니퓰레이터의 개발을 위한 기구학적 분석을 하는 것이다. 구체적인 연구 목적은 매니퓰레이터의 정방향 기구학 및 역방향 분석을 통해 방정식을 구한 후 장치를 작동시켜 반복오차를 측정한 후 이 값을 이론값과 비교하여 검증하도록 하였다.

  • Recently many developed countries have used satellite images for classifying cropland areas to reduce time and efforts put into field survey. Korea also has used satellite images for the same purpose since KOMPSAT-2 was successfully launched and operated in 2006, but still far way to go in order to achieve the required accuracy from the products. This study evaluated the accuracy of the calculated croplands by using the objected classification method with various satellite images including ASTER, Spot-5, Rapid eye, Quickbird-2, Geo eye-1. Also, their usability and effectiveness for the cropland survey were verified by comparing with field survey data. As results. Geo eye-1 and Rapid eye showed higher accuracy to calculate the paddy field areas while Geo eye-1 and Quickbird-2 showed higher accuracy to calculate the upland field areas.

  • This study consists of an observation of the changes in management and agricultural production of Shinbuk-eup based on the data from the Agricultural, Forestry & Census Report Survey. The following is a short summary and suggestions of the research. First, taking a look at the farming conditions of Shinbuk-eup, it shows that it is extremely polarized into rice paddies and vegetable cropping. Second, using the Tobit model to analyze the factor of determination of farmable lands of the farmers in Shinbuk-eup, the higher the number of family members, the less the hired work, and the more the experience in farming, have larger farmable lands. Meanwhile, the younger the farmer, their land mass is higher, however, after reaching their threshold age, their lands decrease.

  • China is the country with more people and more land, faced with the pressure of population growth and land decrement. The potential of developing animal husbandry by increasing feed grain per capita is less and less. "Planting forage to feed livestock" is a sustainable industry with grain-saying, high efficiency, good quality and safety, accorded with the conditions of China. First, the natural, social and economical condition in southern area of China was analyzed, and the characteristics of production and utilization of forage were introduced in this paper. The natural condition in southern area of China was well suited for forage production. Forage was mainly planted on famland. Main herbage cultivars were annual or hibernal annual. Most of forage was directly utilized by herbivorous animal and fish. Second, The present situation, developmental trend and existing problems of forage industrialization were reviewed. The level of forage industrialization was low with a bright future. At present, the chief existing problems were lack of herbage cultivars of good quality, backward equipment, lagged techniques and low level of mechanization in forage processing with a short time and so on. Finally, the situation of production and utilization of forage was summarized.

  • This study was carried out to investigate the changes of forest land use around Tae Kwan Ryoung region during 15 years, by using the aerial photographs in 1965 and 1980 respectively. the results are summarized as follows: 1) The areas of forest land and farm land has been decreased, while the grass land increased as 3 times. It is because that the site of Tae Kwan ryoung region was suitable for livestock breeding and the wide grass lands were developed. 2) With a view to forest land use, it is desirable to convert the forest land into grass land and farm Land. But it should be considered the fact that most of the farm land was converted into forest land, in the utilization of forest land in future. 3) Due to the development of industries such as livestock breeding and leisure industry, there is a great increase in the dwelling houses, stalls, public building and habitants in this region. Therefore, in future we should establish the plans of forest land use synthetically and efficiently, considering the promotion of indirect utilities such as soil conservation, recreation and environmental protection as well as timber production.
