  • For an efficient management and utilization of marine biodiversity information, we made an attempt to develop the Korea Marine Biodiversity Information System (KoMBIS), building a species name inventory of Korea marine organisms. The inventory includes 17 organism groups: phytoplankton, zooplankton, algae and halophyte, sponges, cnidarians, rotifers, nematodes, bryozoans, brachiopods, molluscs, echiurans, annelids, arthropods, echinoderms, urochordates and fish. The species names were collected from 37 different references and reviewed for validity by taxonomists, which resulted in 9,798 valid names in addition to 1,845 synonyms. The Korea marine species inventory is the first one of this kind, for previous Korean species name inventories were mostly composed of terrestrial and freshwater organisms. KoMBIS, the information system developed, contains not only the species name but also information on morphological and ecological characteristics such as distribution, DNA barcode, and references. This system is convenient for the inputting of new data and servicing users through the internet, so that management and utilization of the biodiversity information is more efficient. Linking the DNA barcode data with species information provides an objective measure for identification of a species, which accommodates the recommendation of Consortium for the Barcode of Life, and makes the Korea marine biodiversity information compatible with international databases. Considering the frequent exchange of marine organisms internationally via ballast water and such issues as climate change, this information system will be useful in many areas of marine biodiversity.

  • 본 연구에서는 우리나라 대나무 자원의 평가를 위하여 GIS 기반의 인벤토리를 구축하고 활용 방안을 제안하였다. 대나무 자원의 일반현황, 임황 및 지황 정보, 입지토양 정보 등의 인자를 추출하고 현지표본점 조사를 통해 획득한 자료를 활용하여 면적 및 축적량을 산출하여 통합하였다. 구축된 인벤토리는 방치되어 있는 대나무 자원의 건강성 및 지속성 확보는 물론 대나무의 기능 증진을 위한 장기적인 목표와 방향을 설정할 수 있는 의사결정 도구로 활용할 수 있을 것으로 판단된다.

  • Forest inventory is a commercial term meaning the preparation of detailed descriptive list of articles with number, quantity and value of each item included. Forest inventory deals with the measurement of trees and stands, the estimation of their volume, growth prediction, biomass, carbon stocks and the description tree characteristics, as well as the land upon which they are growing. National Forest Inventory Center (NFIC) in Korea conducts national forest inventory every 5 years to obtain accurate baseline data for national forest policy. The permanent sample plot data used in were collected by NFI. The objective of this study was to develop methods for quantifying forest resources at national scale based on $5^{th}$ National Forest Inventory (NFI) data in Korea. Forest land area decreased from 6.44 to 6.38 million ha between 1997 and 2007, continuing a slight downward trend in area beginning in the late 1990s. However forest resources of the Korea have continued improving in general condition and quality, as measured by increased average size and volume of trees. Growing-stock volume of the Korea increased from 17 to 123.79 cubic meter per ha between 1976 and 2007. The biomass in Korea was estimated to be 153.81 tons per hectare and carbon stocks in Korea was estimated to be 84.36 tons per hectare by NFI data. This information is important for government officials, public administration, the private business sector, and the researcher. Forest Inventory should be implemented in a way to be able to monitor and assess the forests continuously.

  • Natural ecosystem is an essential part to connect with the plan for biodiversity conservation in response strategy against climate change. For connecting biodiversity conservation with climate change strategy, Europe, America, Japan, and China are making an effort to discuss protection necessity through national biodiversity valuation but precedent studies lack in Korea. In this study, we made biodiversity maps representing biodiversity distribution range using species richness in National Forest Inventory (NFI) and Forest Description data. Using regression tree algorithm, we divided various classes by decision rule and constructed biodiversity maps, which has accuracy level of over 70%. Therefore, the biodiversity maps produced in this study can be used as base information for decision makers and plan for conservation of biodiversity & continuous management. Furthermore, this study can suggest a strategy for increasing efficiency of forest information in national level.

  • 연안지역의 자원을 효과적으로 관리하고 현명한 계획을 하기 위해서는 개별 습지의 위치, 크기, 분포와 규모에 관한 정보와 인근 지역의 토지이용 정보가 필요하다. 지리정보체계와 원격탐사 기법에 의해 이러한 정보를 나타내는 습지목록을 제작하는 것은 전형적인 현장 조사와 지도제작방법에 의해 만들어진 자료보다 효율적이다. 더욱이 이렇게 만들어진 목록은 습지의 관리에 필요한 여러 용도로 활용될 수 있다.

  • Acquiring accurate quantitative and qualitative information is necessary for the technical and scientific management of forest stands. In this study, stratification and systematic random sampling methods were used to estimation of quantitative characteristics in study area. The estimator ($((E%)^2xT)$) was used to compare the systematic random and stratified sampling methods. 100 percent inventory was carried out in an area of 400 hectares; characteristics as: tree density, crown cover (canopy), and basal area were measured. Tree density of stands was compared through systemic random and stratified sampling methods. Findings of the study reveal that stratified sampling method gives a better representation of estimates than systematic random sampling.

  • This study was conducted to support for determining an efficient sampling design for forest resources assessments in South Korea with respect to statistical efficiency. For this objective, different systematic sampling designs were simulated and compared based on an artificial forest population that had been built from field sample data and satellite data in Yang-Pyeong County, Korea. Using the k-NN technique, two thematic maps (growing stock and forest cover type per pixel unit) across the test area were generated; field data (n=191) and Landsat ETM+ were used as source data. Four sampling designs (systematic sampling, systematic sampling for post-stratification, systematic cluster sampling, and stratified systematic sampling) were employed as optimum sampling design candidates. In order to compute error variance, the Monte Carlo simulation was used (k=1,000). Then, sampling error and relative efficiency were compared. When the objective of an inventory was to obtain estimations for the entire population, systematic cluster sampling was superior to the other sampling designs. If its objective is to obtain estimations for each sub-population, post-stratification gave a better estimation. In order to successfully perform this procedure, it requires clear definitions of strata of interest per field observation unit for efficient stratification.

  • The inventory list of wildlife species inhabiting or distributing in Gyeonggi Province was made by compiling species data from precedent surveys, 10 national level nature surveys, 1 survey that Gyeonggi-do conducted, and 46 local surveys presented in scientific journals. Total 2,913 wildlife species including 2,041 vascular plants, 39 mammals, 304 birds, 34 herptiles, 145 fish, and 350 benthic macro-invertebrates were listed in the inventory. It explains 47% of nationwide total species in vascular plants, 31.5% in mammals, 58.2% in birds, 65.4% in herptiles, 12.2% in fish. The total number of important species including endangered species, national monuments, national red lists, etc. was 628 species, accounting for 21.6% of all listed species in Gyeonggi Province. More than 90% of endangered bird species, almost half of endangered fish and herptile species were found in Gyeonggi Province. In particular, abundant bird diversity and inhabitation of many endangered bird species were identified in Gyeonggi Province. Species diversity was greater in the northern area adjacent to the Demilitarized Zone and the eastern forest area. The distribution of the important species such as national endangered species was more distinct in these areas, especially in Gapyeong and Yeoncheon Counties. The inventory list compiled in this study implicates the level of management for biological resources and can provide information for policy decisions regarding new survey sites, protection management of specific species and areas, management practices by spatial characteristics. It should be more compiled and updated with survey data to be utilized as basic indices for local biodiversity strategies and management of biological resources.
