토양 변수는 작물 모형을 통한 기후변화 시나리오 조건에서의 작황 예측에 있어 중요한 환경적 요소이다. 토양 환경 정보 시스템 (Korean Soil Information System; KSIS)에서는 390 개의 토양통에 대한 자세한 정보를 제공하고 있다. 그러나, 이러한 토양 정보는 HTML (Hyper Text Markup Language) 문서 형식으로 제공되고 있어 작물 모형용 토양입력 자료로 변환하는 데에 어려움이 있다. 이에 따라 KSIS의 토양정보를 기반으로 작물모델의 토양 입력자료를 생산하는 도구인 Korean Soil Information System Processing Tool (KSISPT) 를 개발하였다. 이 도구는 객체 지향 프로그래밍 언어인 JAVA로 작성되었으며 여러 개의 모듈로 구성되었다. 이 모듈들을 통해 각각 KSIS 웹 페이지 문서 분석, 토양 자료 저장, 추가 변수 생성, 토양 입력자료 출력 등의 기능이 구현되었다. 각 토양통의 특성을 고려한 총 940여개의 토양 입력 자료가 생성되었다. 이 토양 자료를 KSIS에서 제공하는 30m 해상도의 토양통 공간적 분포 지도와 함께 활용된다면, 미래 기후 조건에서 작물 생산성의 시공간적 분석이 용이해지고 이를 기반으로 기후 변화 적응 대책수립에 도움을 줄 수 있을 것이다.

It has been a common practice to use manually processed soil maps in planning of land readjustment. This study is intended to develop a geographic information system for computerized processing of soil maps. The detailed soil maps were drawn using the geographic information system, and analyzed and compared with manually processed maps. The soil maps, in conjunction with a computer program of land readjustment design, can be applied in estimation of soil works appropriate for the given soil condition, and also in selecting the efficient construction equipments. The study results prove that the proposed methods based on the geographic information system can be used effectively in preparing soil maps for design of land readjustment.

Surface soil is one of the most important resources that have many functions for human needs such as conservation of water resource, purification of contaminated materials, and productivity of food or energy. However, the surface soil is a limited resource that cannot be recovered readily for a long time once it is lost by erosion. In Korea, the Ministry of Environment enacted the notification on the investigation of surface soil erosion and corresponding countermeasures. As the results, database of soil quality assess criteria (biomass, groundwater recharge, habitat, carbon storage, buffer, and soil loss) was established, and the web-based system that can evaluate surface soil conditions was developed. However, non-experts have difficulties in using the system because the system requires in-depth knowledge about soil qualities. In this study, the Web Geographic Information System (GIS) watershed-based surface soil information system was developed to improve usability of the system and accessibility of soil quaility database. The system provides the current condition of surface soil characteristics and GIS-based soil data at selected locations. The users are able to download soil quality data in different districts, watersheds, and special regions allocated by TauDEM module. The system developed in this study would valuable surface soil information for studies of soil quality and its environmental effects, and thereby contributing to establishing more appropriate and robust soil conservation laws.

현재까지 경지정리 조사설계를 위한 토양조사결과 처리, 토양도 제작 분석 및 그에 따른 적절한 건설기계 선정은 모두 수작업에 의해 이루어져 왔다. 본 연구에서는 지리정보시스템을 이용하여 이러한 작업을 전산화하였다. 다양한 토양 분포 양상을 띠는 산간지역경지정리 조사설계 지구의 현장조사 및 실내분석 시험치에 대한 자료를 수집하여 기본도와 주제도를 작성하고, 데이터베이스를 구축하였다. 이를 분석하여 대상지역의 경지정리시 사용되는 적절한 건설기계 선정방안을 제시하고 기존의 수작업 내용과 비교 검증하였다.

The objective of this research was to develop a framework of the Soil Environment Information Management System (SEIMS). In this study, we found that the SEIMS needs to be consisted of three sub-systems (i.e., information input system, DB system, and opening to the public system), which is operated on the Web-GIS basis. Also, we suggested structure and detailed items for each sub-system which are acceptable under the basis of current legal and institutional system. Furthermore, we made several suggestions for future-oriented system. Further researches need to be pursued for developing efficiently the SEIMS, such as 1) DB standards for the SEIMS, 2) guidelines for each cleanup phase, 3) improvement of the SEIMS for groundwater quality, and 4) integrated SEIMS for both soil and groundwater system.

Amount of soil loss is important information for the proper water quality management, In this research, annual average soil loss of the Geum River basin was estimated using RUSLE (Revised Universal Soil Loss Equation) and GIS (Geographic Information System). Input data were manipulated using ArcGIS ver. 8.3. From crop field which constitute 8.2% of the Geum River Basin, annual average soil loss was estimated as 53.6 ton/ha/year. From the rice paddy field which constitutes 20% of the Geum River Basin, soil loss was estimated as 33.5 ton/ha/year, In comparison, forestry area which constitutes 61.8% of the basin discharged 2.8 ton/ha/year, It could be known from this research that appropriate measures should be implemented to prevent excessive soil loss from the agricultural areas.

Constructing the national inventory that can be used as a tool to identify and assess existing or potential contamination is necessary for efficiently managing the soil and groundwater contamination. In order to start this construction, the first step is how we define and classify potential contamination sources of soil and groundwater. After selecting the basic classification model of contamination sources from developed countries, we suggested the classification and list of the potential contamination sources of soil and groundwater which are appropriate for specific conditions of South Korea. In addition, we investigated several databases to confirm the existence of available data sources and then examined established attribute data through chemical accident response information system (CARIS) and water information system (WIS) in National Institute of Environmental Research and mine geographic information system (MGIS) in Mine Reclamation Corporation. All sorts of attribute data in the existing databases can be utilized as significant assessment factors for determining the management priority of potential contamination sources in the future. Therefore, it is required the expanded investigation of additional database sources and the continual modification so that the classification system of potential contamination sources can be improved.

Agricultural information was discussed for suggesting tasks and solutions of knowledge based information system. States of agricultural information systems in rural development administration were described and problems and tasks were summarized in knowledge needs survey of farmers who have to decide many alternatives for farming. Hard to access information are soil state, disease and insect pest. Important information in agriculture are water, soil fertility, soil physical property, and accessibility from main road. In conclusion, knowledge based agricultural information system can be developed based on surveyed needs.

In this paper, we propose a ubiquitous Farming Diary System which can support the easy and reliable recording of a farming diary for the certificate on environment-friendly agricultural products by using the USN(Ubiquitous Sensor Network) technologies. By using growth-related data, the system can also control farming facilities remotely and automatically. To achieve this goal, the UFDS(Ubiquitous Farming Diary System) is consisted with 3 layers. The first 'physical layer' can collect data from sensors, cameras and facilities then controls the growth environment based on the analyzed information. The second 'Middle layer' can process and store the data from 'physical layer' to sensor manager, image manager, control manager and diary manager separately. The third 'application layer' can provide growth-related services to users through various applications. The UFDS can recording grow history information automatically and Easily. Besides, the system can make an accurate and reliable farming diary with multimedia information such as motion and sound. Furthermore, environmental information such as temperature, humidity, luminance and soil conditions (soil temperature, soil humidity, soil EC) can be monitored in real-time and the facilities managed in remote sites.
