  • This study was tried to find out the applicability of decision support system for forest land use conversion, which developed based on algorithm for forest land-use conversion. Decision support system developed by Ministry of Safety Administration is free from the existing licensed laws omission. And it made the input requirements for each value of the final result so that you can determine whether the permit was available by the laws and regulations related to the algorithm for forest land use conversion. Also, in order to do field surveys, equal sampling interval method is used to extract samples for the operability by comparing and analyzing the actual area. As a result, 88 areas of total 100 areas are able to get permission by the decision support system for forest land use conversion, and it means if there is enough data with sufficient research, it can make the availability permits easily.

  • The land use of the unit watersheds should be maintained appropriately in order to keep the load allotment stable for the management of Total Maximum Daily Loads (TMDLs). This study classified the land area in four types and analyzed the use of each land type and its changing pattern by calculating the occupation and conversion ratios for the unit watersheds in three river basins. The forest land showed the greatest occupation ratio with 63.0%, followed by the farm land with 23%, the other area with 8.0% and the site area with 6.0% in 2003. The occupation ratio of the site and the other area increased by 0.4% and 0.2% respectively, and that of the farm and the forest land decreased by 0.4% and 0.2% respectively in 2007. The conversion ratio for the site area ranged from 1.65% to 1.97%, for the farm land from -0.47% to -0.33%, for the forest land from -0.10% to -0.04% and for the other area from 0.17% to 1.97%. It can be inferred that the decrease in the farm and the forest land contributed to the increase in the site area and that the increase in the other area was mainly made by the decrease in the forest land. It could be more effective to take into account the changes in the site area and in the forest land in the process of developing the TMDL plans.

  • As a pre-step research to make land-use planning in the region level, this study aims to analyze some probability pattern representing transition probabilities from farmland to others using the sequential detailed digital land-use maps. Kinki and Chubu regions of Japan, which have Osaka and Nagoya cities as their center places respectively, were selected as test regions in this study. The 10m grid land-use maps for four time series at every 5 year from 1977 to 1992 were used. In this study, the regions were divided into three sub-areas 10km, 20km, and 30km according to distance from center cities, respectively. The correlation coefficient (CC) between sub-areas with same distance in the two regions was calculated to analyze whether or not the two regions have common points in the pattern of land-use conversion probability from farmland to other types. The probability distribution of the converted areas which were moved to the urbanized area (residential, commercial, industrial, road, park and public facility areas) was about $40{\sim}70%$ for both all periods and sub-areas. According to distance from city centers, the probability moved to the urbanized area was about 60% at 10km area, and 40% at the 30km area, which means that the values we decreased gradually, while in the case moved to the forest and the etc areas, the values were increased slightly. The CC analysis from the paddy field and the dry field to the others separately showed that there is high correlation in the probability pattern between the two regions.

  • 도시의 외연적 확산은 도시 주변부의 농지나 녹지지역을 도시적 용도로 전환시킨다. 도시주변부의 개발은 도시기반시설의 설치비용 및 교통비용 등 여러 가지 사회적 비용을 수반한다. 도시의 확산과정에서 새롭게 개발되는 도시 주변부의 개발특징을 파악하고 이를 합리적으로 관리하는 것은 지속가능한 도시발전을 위한 중요한 과제이다. 본 연구는 대구광역시를 대상으로 1990년과 2000년 사이 도시주변부의 신개발지를 대상으로 위성영상, 토지관리정보시스템, 인구 및 주택총조사 자료 등을 GIS로 구축 활용하여 토지이용전환에 영향을 주는 요인, 토지이용현황 및 공간적 분포, 개발 밀도 등을 중심으로 개발특성을 도출하였다. 분석결과 대구광역시의 도시지역의 확장은 주거지 개발이 주도한 가운데 지역에 따라 산업단지 및 유통단지 등의 형태로 토지이용의 차이를 보였다. 이러한 결과를 기초로 도시개발의 입지, 규모, 밀도 등의 도시성장관리에 필수적인 다양하고 유용한 정보를 제공할 수 있었다.

  • 토지 이용 변화는 토양 내 유기물과 양분 상태에 영향을 줄 것으로 기대된다. 본 연구에서는 경기도 광주군 검단산 일대에서 과거 논으로 이용되다가 현재는 버드나무-신나무 우점의 산림으로 변한 지역, 밭에서 잣나무 인공조림지로 변한 지역, 그리고 과거부터 지속적으로 참나무류가 우점하고 있는 산림 지역 등 세 가지 토지 이용 형태를 선정하고 여기에서 토양 내 탄소와 질소의 농도, 토양 호흡, 그리고 질소 유효도 등을 측정, 비교하였다. 경작지의 휴경 후 20년이 경과한 다음, 토양 내 탄소와 질소의 농도는 토양 깊이 0-10cm, 10-20cm에서 과거 논이었던 지역이 다른 지역에 비하여 높은 것으로 나타났다. 또한 일반적으로 탄소와 질소의 농도는 표층에서 높고 토양 깊이가 증가할수록 점차 낮아지는 경향을 보였다. 이것은 유기물의 유입과 분해의 차이로 인한 축적량이 과거 논이었던 지역에서 가장 많기 때문이며, 탄소와 질소의 증가는 주로 표층에 국한한데에 기인하는 것으로 보인다. 토양 발생 이산화탄소량은 논에서 산림으로 변한 지역에서 가장 높게 나타났으며, 이는 토양 내 높은 탄소 농도와 습윤한 수분 조건 때문인 것으로 보인다. 이온교환수지봉지법으로 측정한 토양 내 질소 유효도는 토지 이용 형태에 따라 유의한 차이를 나타내었는데, 무기태 질소 $NH_4{^+}+NO_3{^-}$)의 유효도와 암모니움태 질소의 농도는 산림지역에서 가장 높고, 밭에서 산림으로 변한 지역, 논에서 산림으로 변한 지역의 순으로 점차 감소하였다.

  • The primary purposes of this study are to identify the characteristics of land development in urban area through GIS and remote sensing techniques and to provide useful implications for urban spatial policy. To perform these tasks, Daegu metropolitan city and its vicinities were selected as a study area, and remote sensing data and attributed data were collected, organized and analyzed. This study focuses on the following three steps. First, it identifies the characteristics of land development in urban areas by utilizing multi-temporal satellite image data (Landsat TM, 1980, 1985, 1990, 1995, 2000 and 2005). Second, it tries to find an answer on a critical question concerning land use conversion, i.e., which land use leads expansion of urban area? Third, it derives implications for urban spatial policies based on these findings. The characteristics of the urban extents tell us that the main land use converted into urban use from non-urban uses is green areas. The public sector, central and local governments, leads the land use conversions of suburban lands as exclusive legal body to issue permission of land use change. Based on these findings, this study concludes that the more systematic and technically advanced management tools should be utilized for more effective spatial management for urban growth.

  • It is very important for successful construction to estimate the soil volume conversion factor of domestic weathered ground accurately and reasonably. However, it is very difficult to quantify the weathering degree of weathered ground at the field, so that the soil volume conversion factor used in Korea is often dependent upon the standard of foreign countries. Besides, the soil volume conversion factor of domestic weathered ground has been rarely studied and the use and accuracy of the soil volume conversion factor have been questioned persistingly. This study suggests a simple but robust method for estimating the soil volume conversion factor and measuring the weathering degree reasonably, and attempts to establish the utilization of a soil volume conversion factor measurement system based on experimental and analytical results. We made relationship between electrical resistivity and weathering degree presented from weathering index obtained through laboratory tests using field samples, and an estimation method of in-situ weathering degree for granites and a calculation method of soil volume conversion factor using electrical resistivity. And also, we suggested the photogrametry measurement-equipment system for measuring the volume of cargo box and the application plan of stand equipment and RFID for calculating the earth volume and distinguishing buggies in order to design the measurement system for soil volume conversion factor applicable to the field. Ultimately, the Weathered Earth-work Management Program (WEMP) was developed, so field managers may easily obtain the information about earth volume and soil volume conversion factor at the weathered ground.

  • The fact that soil loss causing to increase muddy water and devastate an ecosystem has been appearing upon a hot social and environmental issues which should be solved. Soil losses are occurring in most agricultural areas with rainfall-induced runoff. It makes hydraulic structure unstable, causing environmental and economical problems because muddy water destroys ecosystem and causes intake water deterioration. One of three severe muddy water source areas in Soyanggang-dam watershed is Jawoon-ri region, located in Hongcheon county. In this area, many cash-crops are planted at illegally cultivated agricultural fields, which were virgin forest areas. The purpose of this study is to estimate soil loss with current land uses (including illegal cash-crop cultivation) and soil loss reduction with land use conversion from illegal cultivation back to forest. In this study, the Sediment Assessment Tool for Effective Erosion Control (SATEEC) ArcView GIS system was utilized to assess soil erosion. If the illegally cultivated agricultural areas are converted back to forest, it is expected to 17.42% reduction in soil loss. At the Jawoon-ri region, illegally cultivated agricultural areas located at over 30% and 15% slopes take 47.48 ha (30.83%) and 103.64 ha (67.29%) of illegally cultivated agricultural fields respectively. If all illegally cultivated agricultural fields are converted back to forest, it is expected that 17.41% of soil erosion and sediment reduction, 10.86% reduction with forest conversion from 30% sloping illegally agricultural fields, and 16.15% reduction with forest conversion from 15% sloping illegally agricultural fields. Therefore, illegally cultivated agricultural fields located at these sloping areas need to be first converted back to forest to maximize reductions in soil loss reduction and muddy water outflow from the Jawoon-ri regions.
