  • Recently, the development project is conducting disaster effect estimation to breed disaster, and cope these disaster beforehand provoking soil erosion and flood. Therefore, it is important to analyze and reduce of these disaster. In this study, it is intended to extract LS and C factors of soil erosion through the digital image. The photogrammetric technique, which employs the Remote Control Helicopter equipped with a non-metric digital camera, was used for the efficient survey and analysis of cutting slopes. As a result, we obtain more objective value of soil erosion factor using digital image.

  • 한반도의 기후변화는 전 세계 평균보다도 빠르게 진행되고 있다. 최근 빈발하고 있는 태풍 및 극한 강우, 폭설과 한파, 온난화 현상 등이 그 예이다. 특히 북한지역은 오랜 식량난과 에너지난으로 산림생태계가 훼손되어 홍수 및 이수와 같은 기후변화 관련 자연재해에 매우 취약하다. 이렇게 예상되는 대규모 자연재해를 대비하고 기후변화에 효율적으로 대처하기 위해서는 체계적이고 과학적인 기상 및 기후 예측 정보의 활용이 매우 중요하다. 하지만 북한지역은 우리가 수문자료를 구하기가 힘들고, 직접 측정을 할 수 없으므로 수문자료의 수집에 한계가 있기 때문에 기후변화관련 수문연구에 한계점이 있다. 따라서 본 논문에서는 WMO에서 제공하고 있는 북한의 27개 기상관측소의 강수량, 기온자료와 기상청의 RCP8.5기후변화시나리오를 제공 받아 각 관측소별 미래 잠재증발산량을 산정하였다. 또한 lumped conceptual model인 WASMOD 모형을 이용하여 북한의 대표유역(금야강, 대동강, 두만강, 압록강, 예성강, 임진강, 장연남대천)에 적용하여 부족한 수문시계열자료를 산정하였다. 이렇게 산정된 북한의 미래 수문순환요소의 시계열자료를 이용하여 통계분석, 변화점분석, 유황분석등 시계열 분석 등을 통해 RCP8.5기후변화시나리오 기반의 기후변화가 북한지역의 수문순환과정에 미치는 영향을 분석하고, 이를 통해 유역규모의 수자원에 미치는 영향을 전망하였다.

  • Mt. Taegi (1,261.4 m) located in Gangwon-do, is a geographically important region for plant biodiversity. But the biodiversity of Mt. Taegi has been seriously damaged by the invasion of foreign plants, the development of forests and so on. We conducted 21 field surveys between April and August in 2008 and March and October in 2018 to investigate the vascular flora in Mt. Taegi. Total 662 taxa were identified including 96 families, 338 genera, 580 species, 4 subspecies, 66 varieties and 12 formas. Among them, 28 taxa were Korean endemic plants and 8 taxa were rare plants designated by the Korea Forest Services, and 11 taxa were listed on the Red list of endangered plants and 127 taxa were designated as the floristic regional indicator plants according to the Ministry of Environment. The alien plants were 45 taxa, including R. acetosella that is the ecosystem disturbing species.

  • This study was carried out to on liana dominating at the vicinity of Onsan Industrial Complex declining P. thunbergii foersts. It was surveyed 16 species, 30 species and 50 species at upper, middle and understory, respectively. It was dominant P. thunbergii at upperstory, and P. densiflora, P. thunbergii, Quercus dentata and Q. serrata at middlestory, and Smilax china, Paederia scandens, Symplocos chinensis var. sinuata, Styrax japonica, Lonicera japonica and Q. serrata etc. at understory. It was the highest importance value(13.2) of S. china among all liana, and in order of L. japonica (11.7), P. scandens (11.5) and Cocculus trilobus (7.7). Number of species, Species diversity, Maximum species diversity, Evenness and Dominance of woody plants at upperstory and middlestory by each survey site were higher in forest areas than industrial complex, but those of understory highly showed at industrial complex, and ratio of liana at understory was high. It showed total 50 species at herbaceous plants, and was high I.V. of Pteridium aquilinum var. latiusculum, Spodiopogon cotulifer, Commerelina commuris, Phytolacca americana, Rubus parvifolius, Miscanthussinensis var. purpurascens and Calamagrostis arundinacea, etc.

  • Open-pit mine development requires continuous management because of topographical changes and there is a risk of accidents if the current status survey is performed directly in the process of calculating the earthwork. In this study, the application of UAV photogrammetry, which can acquire spatial information without direct human access, was applied to open-pit mines development area and analyzed the accuracy, earthwork, and mountain restoration plan to determine its applicability. As a result of accuracy analysis at checkpoint using ortho image and Digital Surface Model(DSM) by UAV photogrammetry, Root Mean Square Error(RMSE) is 0.120 m in horizontal and 0.150 m in vertical coordinates. This satisfied the tolerance range of 1:1,000 digital map. As a result of the comparison of the earthwork, UAV photogrammetry yielded 11.7% more earthwork than the conventional survey method. It is because UAV photogrammetry shows more detailed topography. And result of monitoring mountain restoration showed possible to determine existence of rockfall prevention nets and vegetation. If the terrain changes are monitored by acquiring images periodically, the utility of UAV photogrammetry will be further useful to open-pit mine development.

  • The purpose of this study is to propose a ventilation corridor management plan to improve the thermal environment for Busan Metropolitan City. To this end, the characteristics of hot and cool spots in Busan were identified by conducting spatial statistical analysis, and thermal image data from Landsat-7 satellites and major ventilation corridors were analyzed through WRF meteorological simulation. The results showed the areas requiring thermal environment improvement among hot spot areas were Busanjin-gu, Dongnae-gu, industrial areas in Yeonje-gu and Sasang-gu, and Busan Port piers in large-scale facilities. The main ventilation corridor was identified as Geumjeongsan Mountain-Baekyangsan Mountain-Gudeoksan Mountain Valley. Based on the results, the ventilation corridor management strategy is suggested as follows. Industrial facilities and the Busan Port area are factors that increase the air temperature and worsen the thermal environment of the surrounding area. Therefore, urban and architectural plans are required to reduce the facility's temperature and consider the ventilation corridor. Areas requiring ventilation corridor management were Mandeok-dong and Sajik-dong, and they should be managed to prevent further damage to the forests. Since large-scale, high-rise apartment complexes in areas adjacent to forests interfere with the flow of cold and fresh air generated by forests, the construction of high-rise apartment complexes near Geumjeongsan Mountain with the new redevelopment of Type 3 general residential area should be avoided. It is expected that the results of this study can be used as basic data for urban planning and environmental planning in response to climate change in Busan Metropolitan City.

  • Ecological restoration is an eco-technology, which heals the nature damaged by human activity by imitating organization and function of the integrate nature and thereby provide an inhabitable space for diverse organisms. Such an ecological restoration has to be carried out by applying restoration plan prepared based on the results of diagnostic evaluation discussed in the diversified respects. This study aims to prepare an ecological restoration plan of the damaged forest ecosystem in Mt. Moodeung National Park. To arrive at the goal, first of all, we diagnosed quality of forest landscape established in Mt. Moodeung National Park based on natural (topography, climate, and distribution of vegetation) and artificial (land use, linear landscape element) factors. In addition, we evaluated the integrity of each zone divided by linear landscape element quantitatively based on geometric property and land use intensity. As the result of analysis, topography of Mt. Moodeung National Park tended to be depended on weathering property of parent rock and vegetation zones were divided to three vegetation zones. Based on land use pattern, deciduous broad-leaved forest, evergreen needle-leaved forest, and mixed forest occupied about 90% of Mt. Moodeung National Park. Mean score of forest landscape quality was shown in $69.86{\pm}11.41$. As a result, forest landscape elements in Mt. Moodeung National Park were influenced greatly by human activity and the degree was depended on topographic condition. This study suggested the synthetic restoration plan to improve ecological quality of Mt. Moodeung National Park based on the results of diagnostic evaluation.
