韓國 四森林帶의 소나무林에 관한 植物社會學的 硏究

林暎得,姜鎬監,中越信和 仁川敎育大學校 1991 論文集 Vol.25 No.2

Four climatic forest zones were set up for the investigated areas in South Korea. A phytosociological study showed little differences in C, N and C/N ratio except for available phosphorus and pH. A correlation between DBH and tree height showed a similar tendency of DBH and age in all investigated areas. The nerer the villages, more human impact on vegetation was observed. In addition, men's impacts were considered to be a significant environmental foctor in growth rate of P. densiflora populations.

Estimating Direct Runoff from Storm Rainfall Using NRCS Runoff Method and GIS Mapping in Vientiane City, Laos

Vannasy M.,Nakagoshi N. 보안공학연구지원센터 2016 International Journal of Grid and Distributed Comp Vol.9 No.4

The amount of direct runoff present in a watershed indicates the hydrological condition of the area, reflecting the characteristics of land use, soil and rainfall distribution. This study aims to measure the hydrological condition of Vientiane city by examining the runoff potential. This study obtained direct runoff from storm rainfall for the city area which covered the Mark-Hiao River watershed. The rainfall-runoff calculation is useful for future design of drainage networks within a watershed to support flooding management. The Geographical Information System (GIS) software is the main technology used in this study for the purposes of assigning the estimating process, watershed delineation, extracting hydrologic parameters and mapping. There are two main parts discussed with useful results in this study, delineating the river watershed and estimating weighted direct runoff for a watershed area. The result of delineating river watershed process, showing the changing elevation data achieved by combining the two elevation data, Shuttle Radar Topography Mission 30m Digital Elevation Model (STRM 30m DEM), and digital contour data (Vientiane database), performed well in terms of representing surface flow networks and their topography. The calculated average of direct runoff in each small sub-watershed estimated by using Weigh-Q method of the National Resources Conservation Service (NRCS) very well showed the poor to good hydrologic condition in each specific area in 1-to5-day durations of storm events.

Landscape Ecological Study on the Habitats of Aconitum pseudo-leave var. erectum (Ranunculaceae) and Its Distribution

Shin-Ho Kang,Nobukazu Nakagoshi,Sung-Chul Ko 한국자원식물학회 2001 Plant Resources Vol.4 No.1

This study was conducted to clarify the floristic composition and to investigate the landscape structure of habitats of Aconitum pseudo-leave var. erectum. A. pseudo-leave is designated an endemic plant in Korea. Floristic compositions of habitats were mainly composed of Quercus mongolica community. Other elements in this composition were Weigela subsessilis, Corylus sieboldiana and Cornus contioversa. Landscape ecological structure of habitats were defined by soils of mesic, loamy skeletal, slope of more than 60°, sixty percent of woody coverage at 460-520m above the sea level and 25m away from drainage. Distribution patterns of A. pseudo-leave var. erectum plants in Taejon were presented on the 1km X 1km grid map.

Comparison of the Initial Demographies of Pine and Oak Populations in Rural Pine Forests in Korea and Japan

Hong, Sun-Kee,Nakagoshi, Nobukazu 한국식물학회 1998 Journal of Plant Biology Vol.41 No.3

In order to understand the human impact upon demographic change in plant population in rural forests, we examined the population trends of Pinus densiflora and Quercus serrata in P. densiflora forests viewing their seedlings and saplings in rural Korea and Japan. The most prominent factor affecting the regeneration of the pine and oak was the intensity of management activity which controlled the vegetation stratification and its light environment. Open spaces, such as graveyard or cleaned area that allow the long-term direct daylight in dry season to accelerate the surface heat of soil, were unfavorable habitats for germination and growth of both species. The negative effects of the presence of litter and evergreen trees were related to the failure of early seedling and sapling growth of pine. Cover of litter is, especially, another factor related to the growth of pine saplings. It is considered that successful germination and sapling growth of pine and oak in early successional stages is determined by vegetation structures and light condition.

Nature-based Tourism in Small Islands Adjacent to Jakarta City, Indonesia: A case study from Seribu Islands

Hakim, Luchman,Hong, Sun-Kee,Kim, Jae-Eun,Nakagoshi, Nobukazu Korean Wetlands Society 2007 한국습지학회지 Vol.9 No.1

In this paper, the nature-based tourism is described as one of the tools to achieve sustainable development in small islands. The study was carried out at Ayer, Bidadari and Onrust Islands of Kepulauan Seribu chains at Jakarta Bay, Indonesia. While the historical records show that previous uses of such islands have started at sixteen century, tourism uses was started at the beginning of 1970s. Among nature-based tourism destination in Kepulauan Seribu chains, these islands are the famous destinations and received a lot of tourists. Tourism growth at these islands has stimulated development of numerous tourism facilities and infrastructure to meet visitor satisfaction. It is observed in this study that island's site-plan destination design has contributed to the successful and sustainability of tourism in small island. The key success lies on the successful integration and implementation of three substantial perspectives into practices, namely economic, ecosystem and social perspectives. First, in order to enhance economic benefits, a site-plan design allowing floating cottages establishment to extent room availability, to build strong images as tropical paradise islands, and to enhance tourist satisfaction with the objectives of improving income and sustaining tourist loyalty to the destination. This design is also reducing land risk from tourism impact and it becomes the significant key of second perspective, the ecosystem perspective. Moreover, the ecosystem perspective has been implemented through native vegetation preservation that led island's wildlife conservation and became potential tourism attraction. The design also develops effective mechanism to manage and regulate visitor flows by establishing visitor track corridors. In implementation, such corridor plays an important role to reduce tourist density in single places and therefore become instrument to reduce severe visitor impact to wildlife, vegetation and heritages of islands. Third, the social aspect of development allowing heritages to conserve and furthermore serve numerous benefits for education, socio-political, culture, and historical studies. Through this study, it is clear that the success of these islands to continuous tourism growth lies on the island's vision to integrate economic, ecosystem and social perspectives on tourism development.
