  • The government is now driving a policy that development of industrial complex site for the local manufacturing industry by reengineering and expanding the existing sites or reclamation of coastal zone. Therefore, it is necessary to analyze the impact of the coastal reclamation work in terms of physical and environmental characteristics. This study is also dealing with the impact of coastal reclamation for national industrial complex site to the ocean physical characteristics, variation of sedimentation and diffusion system and marine environment from the analysis of the field measurement and numerical simulation. The site for application is at the coastal boundary near Onsan national industrial complex, Ulsan metro city. In order to verify the numerical simulation result, it is compared to the collected data for tide, current, and sediments of the existing measurement and field observation at the selected stations for this study. The verified numerical models were applied to the actual field and the future change was analyzed.

  • Although the ecosystem extends numerous functions for the benefit of humankind, construction of horticultural facilities can potentially lead to the degeneration of some of these functions owing to the expansion of impervious regions and loss of habitats. Thus, this study aimed to examine the effect of construction of horticultural facilities on plant biodiversity. Analysis of the vegetation distribution characteristics showed that horticultural facilities had significantly lower plant diversity than did rice paddies. Hence, the proposed approach involved low-impact development, arrangement of habitat space, plant preservation, restricted use of chemical fertilizer, habitat creation, and reduced preservation cost. Lifestyle analysis suggested the importance of developing favorable environments for the growth of annual plants and aquatic plants. In all, 20 species of naturalized plants belonging to 10 families were identified. Furthermore, the proportion of these naturalized plants was higher in glass greenhouses and multi-span greenhouses, suggesting the advantages of employing natural soil mulching while avoiding concrete mulching. Statistical analysis was performed to validate the results, which suggested that impervious regions be converted to natural soils. Collectively, the findings of this study are expected to be used for establishing policies for the construction of eco-friendly and ecological horticultural facilities; this may aid the maintenance of sustainable agricultural landscapes and large-scale development of the reclaimed lands.
