대전천 생태하천복원지역의 지표특성 분석을 위한 원격탐사 자료의 활용 = An Applications of Remote Sensing Data for the Land Surface Characteristics Analysis of Ecological Stream Restoration Area in Daejeon Stream

다국어 초록 (Multilingual Abstract)

Periodic monitoring of stream is an important activity on the long term stream restoration project in terms of supplement and inspection. In the systematic management method, new scientific approaches are also necessary. Through this study, for the purpose of scientific management method, land-cover, NDVI and land surface temperature has been analyzed before and after ecological stream restoration of Daejeon Stream. To achieve this, the land-cover and NDVI distribution maps have been prepared from KOMPSAT-2 images and Landsat-5 and 8 images were used to produce the land surface temperature distribution maps. As a result of the study showed that after ecological stream restoration, urban and bare land was decreased, whereas vegetation was increased. Particularly in stream covering section, the area of water and vegetation were sharply increased. After stream restoration NDVI result shows the high value for all sections, especially the upstream region of the study area. In the land surface temperature change calculation, temperature was risen in most sections. However, those are presumed it this is because used image resolution was not high enough for the real size of stream. According to analysis of surface temperature by distances, the more distance from stream, the more temperature decrease. Therefore, the measurement of land surface temperature as well as analysis of the land-cover and NDVI would be useful to evaluate about land surface properties of ecological stream before and after restoration.
