This study reviews the research trends of landscape ecology, geographical information system(GIS) and remote sensing(RS) that have appeared in articles published in the Journal of the Korean Institute of Landscape Architecture over the last 30 years. The aim is to identify the research characteristics in Korea. There were 905 papers published in the journal during this period. There were 35 papers concerning landscape ecology, and 26 papers concerning GIS/RS, which are few compared to other research fields. The papers were classified chronologically, and reviewed in terms of their contents. In the seventies and eighties, papers were contributed from other disciplines, e. g., forestry, and also included translated papers from foreign sources. However, in the nineties, the number of papers grew continuously. During the fist half of nineties, six papers were published. However, 30 papers were published during the last half of nineties, which shows a rapid increase in the number of papers contributed. From 2001 to 2003, there were 17 papers published. Overall, there tends to be an increase in the number of papers contributed and published.

Landcover change is an important factor that changes structure and function of regional ecosystem. As the rise of concern on environment quality, many studies are trying to quantify and evaluate the landsacpe in recent days. In this study, using landscape indices with RS(Remote Sensing) and GIS(Geographic Information System) technology, spatio-temporal variations of areas and distribution of forest patches were examined in the Chonan from 1985 to 1996. Fragstats 2.0 was employed to analyze and compute 31 landscape indices from 52 landcover maps. A result of this study showed that area of forest and paddy decreased as a result of urban sprawl. Especially from 1993 to 1996, the change of land use progressed rapidly because of merging a city and a country in Chonan. The size of patch in forest had been smaller and irregular form, heterogeneity of size of forest patches within sub-basin increased, and variety of patch types around forest patches increased from 1985 to 1996.

Today, ubiquitous technology (e.g. computers or networked devices pervade everywhere we are) has enlarged by great advancement of information and communication technologies. If ubiquitous technologies is applied to, innovation of spatial information technology is expected. traditional spatial information technologies such as survey, GIS, GPS, LBS, and RS and ubiquitous technology gradual1y have been converged. The aim of this study is to create shared visions in spatial information technologies by scenario based roadmapping. So, we surveyed the state of the art in main spatial information technologies, market status and patent map. Consequently, prospects of spatial information technologies is suggested. The aim of 1st and 2nd NGIS project focused on map supplier was to develop digital map(e.g. framework data, various thematic map). As a result, the best technology of digital mapping is achieved in the world. But, there is not enough to develop GIS and LBS solution. Current market in GIS S/W and Telematics is about 384billon won and 250billion won. a patent is applied in the order, like a USA(1571case, 47%), Japan(883case, 26%), EU(478case, 14%), Korea(446case, 13%). In the future, spatial information technology fused on ubiquitous technology will be focused on user's demand and developing convenience context. The developing target will be realtime monitoring of 3D spatial data based on high resolution coordinate system, sharing and supplying multi-sensor data considered users demand, location service by ubiquitous technologies.

Based on 3-period land use data using RS and GIS, this paper analyzed landuse change and subsequent loss of ecosystem service value, using the ecosystem service value coefficients put forward by Costanza. Results show that from 1917 to 2006, area of crop land, plantation, building site, unused land increased and natural forest, grassland, water area, wetland decreased, in Musan region and Hoeryeung region. But the area of natural forest is acute reduced by 7,925.34ha and the amplitude of building site is increased rapidly in Musan region. The area of grass land is acute reduced by 71,594.34ha and the amplitude of unused land is increased rapidly in Hoeryeung region. Total ecosystem services value of Musan region reduced dramatically, from $66,135.26{\times}10^6$ won to $37,894.51{\times}10^6$ won in period 1917~2006. The net decreased ecosystem services value is $28,240.75{\times}10^6$ won and the increased amplitude is 42.71% in Musan region. Total ecosystem services value of Hoeryeung region reduced dramatically, from $145,862.69{\times}10^6$ won to $106,948.44{\times}10^6$ won in period 1917~2006. The net decreased ecosystem services value is $38,914.25{\times}10^6$ won and the increased amplitude is 26.68% in Hoeryeung region. Therefore, the effective measures should be taken to maintain sustainable development of environment.

The objective of this study is to analyze the landslide hazard areas by combining LRA (Lgistic Regression Analysis) and AHP (Analytic Hierarchy Program) methods with Remote Sensing and GIS data in Anseong-si. In order to classify landslide hazard areas of seven levels, six topographic factors (slope, aspect, elevation, soil drain, soil depth, and land use) were used as input factors of LRA and AHP methods. As results, high-risk areas for landslide (1 and 2 levels) by LRA and AHP of its own were classified as 46.1% and 48.7%, respectively. A new method by applying weighting factors to the results of LRA and AHP was suggested. High-risk areas for landslide (1 and 2 levels) form the new method was classified as 58.9%.
