본 연구는 농업 생태계의 생물다양성 보전에 있어 서식처 기반의 보전 전략을 수립하는데 있어 기본 정보를 제공하기 위해 수행되었다. 연구는 경기도 화성시 팔탄면에 위치한 환경압박이 서로 다른 3개 조사지(농경지와 야산으로 이루어진 조사지 1, 공장이 많이 위치하는 조사지 2, 거주지역이 많이 차지하는 조사지 3에서 4개의 토지이용(야산, 밭둑, 논둑, 하천변)별로 2000년 11월부터 2002년 11월까지 39회의 딱정벌레 군집 조사를 통해 이루어졌다. 본 연구의 주요 결과로 서 딱정벌레 군집 조성, 우점종 그리고 군집 패턴이 토지이용에 따라 다르게 나타났으며, 유사도는 조사지 2와 3의 논둑에서 가장 높게 나타났고, 조사지 2의 야산과 조사지 3의 하천변간의 유사도가 가장 낮았다. 또한 도로에 의해 파편화된 서식처간의 유사도가 서로 다른 서식처 및 조사지간의 유사도보다 낮게 나타났다. 이를 통해 생물다양성 보전과 네트워크 측면에서 농경지 토지이용은 각각이 중요한 역할을 수행하고 있음을 알 수 있다. 본 연구는 국내 농촌경관에서의 서식처별 딱정벌레 군집분석을 통하여 생물다양성 보전에 대한 기초 자료를 제공한다는 점에서 가치를 평가할 수 있다.

종래 농촌개발전략은 농업 및 농민에게 중점을 두고 도시의 편리성을 지향하는 정책이었다. 그러나 농업에 의한 농촌발전의 한계성이 드러나고 도시를 지향하는 농촌의 정주정책은 농촌경관의 획일화를 초래함에 따라 농촌다움이 상실되는 문제점을야기하여 왔다. 이로인해, 농촌다움의 상실은 농촌 자체 매력의 상실을 가져왔으며, 이는 소비자인 도시민으로부터 외면당하는결과를 초래하였다. 이에 따라 농업과 농촌이 가지고 있는 잠재적인 기능과 다면적인 기능에 대한 재평가가 이루어지고있으며 이의 활용을 통한 농촌의 활성화를 모색하는 대안이 제기되고 있다.따라서, 본 연구의 목적은 농촌경관 자원으로서 그 중요성이 커지고 있으며, 활용가능한 자원으로 인식되고 있는 농업생산경관의심리적 특성을 분석함으로써 농촌계획에 있어 활용가능한 심리적 인자를 제시하고자 하며, 이후의 농촌계획 및 경관영향평가에 실질적으로 적용할 수 있는 평가기준을 마련하고자 한다.

We investigated the consumption inclinations of consumers for environmentally-friendly agricultural products (EFAP) for better production and distribution of EFAP. Consumer inclinations in large supermarkets from April 7th to 30th, 2008 were surveyed. Data were analyzed using the SPSSWIN 12.0 program. Results showed that 90.4% of consumers recognized EFAP and 76.4% of those who recognized the products had actually bought the products. Members of the "have purchased group" bought EFAP once a week because they believed these products were safe from hazards, such as pesticide. The amount spent on EFAP was less than 20% of the total food budget and the major consumed items were green vegetables and fruits. The sale location was mainly large supermarkets and agricultural cooperation outlets. Although many people were satisfied with EFAP from the viewpoint of nutritional and sensory qualities and safety compared with general agricultural products, they were notsatisfied with the price. Many consumers trusted that EFAP were safe and nutritional. Members of the "not purchased group" also trusted the nutritional and sensory qualities of EFAP and recognized the safety issue, but they were not satisfied with the price, compared with general agricultural products. Consequently, to succeed in the market, EFAP should maintain the confidence of the consumer while decreasing in price.

In this study, the sensitivity analysis of hydraulic conductivity and separation distance (distance between injection well and pumping well) was analyzed by establishing a conceptual model considering the hydrogeologic characteristics of facility agricultural complex in Korea. In the conceptual model, natural characteristics (topography and geology, precipitation, hydraulic conductivity, etc.) and artificial characteristics (separation distance from injection well to pumping well, injection rate and pumping rate, etc.) is entered, and sensitivity analysis was performed 12 scenarios using a combination of hydraulic conductivity (10-1 cm/sec, 10-2 cm/sec, 10-3 cm/sec, 10-4 cm/sec) and separation distance (10 m, 50 m, 100 m). Groundwater drawdown at the monitoring well was increased as the hydraulic conductivity decreased and the separation distance increased. From the regression analysis of groundwater drawdown as a hydraulic conductivity at the same separation distance, it was found that the groundwater level fluctuation of artificial recharge aquifer was dominantly influenced by hydraulic conductivity. In the condition that the hydraulic conductivity of artificial recharge aquifer was 10-2 cm/sec or more, the radius of influence of groundwater level was within 20 m, but In the condition that the hydraulic conductivity is 10-3 cm/sec or less, it is confirmed that the radius of influence of groundwater increases sharply as the separation distance increases.

This study is a basic research with the aim of developing the method of judging the leakage zone by grasping the habitat characteristic of agricultural reservoir slope in inhabiting characteristics appear differently according to natural inhabiting environment. To this end, this study is intending to investigate slope vegetation using a quadrat technique at Sinheung reservoir located at Gwangsi-myeon, Yesan-gun, Chungnam, and to perform the analysis of importance value using relative frequency and relative coverage, etc. Also, this study intended to present the necessity of having to consider the eco-system of the relevant region in time of a reservoir slope afforestation for the time to come by suggesting that the reservoir slope vegetation after a stable period becomes similar to the regional vegetation by comparing this study result with the existing research which carried out the analysis of importance value of forest vegetation for Yesan Region. The reservoir slope vegetation is similar to the indicator species which appear in the regional forest vegetation, so there was a need to select afforestation species in the light of this in time of slope afforestation. As a result of the analysis of the importance value, this study grasped that there was an emergence characteristic similar to the vegetation at a birthplace of a forest fires because growth and development of forest trees, and perennial plants were restricted by annually implemented brush-cutting work, etc.; however, indigo plant and bush clover , etc. were found to show the characteristic differing from this. Consequently, this study was able to confirm that there is the necessity of having to create the Importance Value Table suited for reservoir slopes by region through a lot more data construction in the near future.

The results highlight the importance of promoting social support and individuals' interests on the agricultural education program to increase the word of intention for agricultural education program. This eventually leads the revitalization and development of agricultural education.

Since FAO introduced the Globally Important Agricultural Heritage Systems(GIAHS) in 2002, 36 sites of 15 countries so far have been listed on GIAHS. This study aims to find the important agricultural heritages of Korea and to prepare the methods for them to be selected as GIAHS. We have analyzed the proposals of the 36 GIAHS listed in order to study the characteristics of their components of the agricultural heritage which worked for being selected. To analyze the components of the agricultural heritage first, agricultural heritage was classified into 13 types and 42 components in light of GIAHS criteria. Then central themes were set to analyze the relevant contents in the proposals. They were, the type of GIAHS Site, significant agricultural landscape, the agriculture-forestry-fisheries-livestock linkage systems, the multi-layered, inter-cropping, circulation cultivation systems, the soil and water management systems, the conservation of agrobiological diversity and genetic resources, the history of the agricultural heritage, the succession of traditional farming techniques, the cultural diversity and so on. Most GIAHS are located in mountains, grasslands, rivers and coasts, desert than in plains, through which GIAHS assure us that it is the heritage of human challenge to overcome the harsh geographic environment and maintain a livelihood. In these sites the traditional farming techniques are carried on, such as mountain clearings, terraced rice paddies, and burn fields, and the unique irrigation systems and agricultural landscapes are well maintained, and the eco-friendly traditional farming techniques utilizing abundant forest resources and agriculture are well handed down. The origin or home of crop growing, a variety of genetic crop storage, the world’s largest crop producer and preserving cultural diversity are also important factors for the selection.

The preaent study was conducted to investigate the effect of mixed seeding of three wheat variwties, ‘Anzunbaengimil’, ‘Jokyoung’, and ‘Sooan’, on agricultural characteristics and quality of plants to select the most suitable mixed seeding ratio. We observed that the yield of plants obtained from the mixed seeding combinations was higher than those obtained from single seeding of the three varieties. The yield was high, especially for the combinations ‘Sooan’ and ‘Anzunbaengimil’ (80 and 20%, respectively) and ‘Sooan’ and ‘Jokyoung’ (90 and 10%, respectively). The protein content of the seedlings obtained from the above two combinations was higher than in the seedling of ‘Sooan’. Based on our results, we suggest that mixed seeding of wheat varieties is more effective than single seeding in improving the yield and quality of plants obtained from mixed seeding.

There is a need to analyze unconfined groundwater behavior since the demand of groundwater use has been increasing. While unconfined groundwater temperature is tend to be affected by air temperature, it is hard to find an empirical study in South Korea. In this research, we try to determine the relationship between daily average air temperature and daily average groundwater temperature by time-sequential analysis of groundwater monitoring wells in Galshin basin in Yesan-Gun, Chungcheongnam-Do. In addition, models to estimate groundwater temperature from air temperature were developed. In this research 101-day moving average method with measured air temperature is used to estimate groundwater temperature. To verify the developed model, estimated values of average groundwater temperature with 101 moving average are compared to the measured data from September 10 2007 to September 9 2008. And, Nash-Stucliff Efficiency and Coefficient of Determination were 0.970 and 0.976, therefore it was concluded that the model allowing groundwater temperature estimation from air temperature is with reasonable applicability.
