Abstract PDF: This study aims to analyze the spatial distribution characteristics and policy implications of geodiversity across South Korea’s metropolitan local governments. We focused on geomorphological resources categorized as grade I or II landforms conservation grades derived from the 5th National Ecosystem Survey (2019-2023). To achieve this, nationwide geomorphological resource polygon data were georeferenced by spatially joining them to administrative boundaries with Korea 2000 coordinate system. The data were then categorized into five major geomorphological types: mountain landforms, fluvial landforms, coastal landforms, volcanic landforms, and karst landforms. Analysis results identified a total of 3,126 graded I-II geomorphological resources, with fluvial landforms (38.3%) and mountain landforms (35.6%) account for over 70% of the total. Coastal landforms (19.7%), volcanic landforms (4.2%), and karst landforms (2.3%) showed a lower overall proportion but tended to be partially concentrated in specific administrative boundaries. According to administrative boundaries, grade I-II geomorphological resources were relatively concentrated in Gyeongsangbuk-do, Gangwon State, Jeollanam-do, and Gyeongsangnam-do. Fluvial landforms were dominant in Gyeongsangbuk-do, Gangwon State, and Gyeonggi-do, while mountain landforms were predominant in Jeollanam-do, Gyeongsangnam-do, and Chungcheong region. Incheon City exhibited a specialized pattern dominated by coastal landforms, while Jeju Special Self-Governing Province showed a dominance of volcanic landforms. Karst landforms were concentrated in Chungcheongbuk-do and Gangwon State, well reflecting the regional specificity of limestone-based landforms. Regional geodiversity is closely linked to the spatial structure of biodiversity, and these findings suggest the necessity for differentiated conservation and management strategies. Particularly, by providing empirical evidence for which landforms types should be prioritized in environmental impact assessments, this study can serve as foundational data for establishing geomorphological-resource-centered spatial conservation policies and ecosystem management strategies.

Abstract PDF: The fish community in the Jin Island (Jindo, Jisan, Munnae, Yulri, 1/25,000 scale) was investigated with the data collected through the 3rd National Ecosystem Survey from April to October in 2012. During the period, 25 species belonging to 7 families were collected. There were 11 biological resources subject to the approval of outbound transfer, including Squalidus gracilis majimae, Abbottina rivularis, Aphyocypris chinensis, Hemiculter eigenmanni, Rhodeus ocellatus, Iksookimia hugowolfeldi, Iksookimia koreensis, Trachidermus fasciatus, Monopterus albus, Macropodus ocellatus and Oryzias latipes. The dominant species was Pseudorasbora parva(26.3%), and the subdominant spaecies was Carassius auratus(16.0%).
Background: In Korea, from 1989 National Ecosystem Survey (NES) was conducted by ministry of environment for every 10 years to cover whole south Korea in 1/25,000 scale. The scope of NES including 8 taxa – vegetation, plant, fish, macro invertebrate, insect, birds, amphibian & reptile, mammal and geomorphology. With the results of ecosystem survey we build up species and ecosystem database based on GIS environment. Ecosystem database is becoming very necessary to understand origins and relationship between human and nature and also to reduce ecosystem disturbance.
New information: An ecological information platform can play important roles as a computing system to collect knowledge, distributed research findings and separated data from researchers. We designed and developed ecological information portal service (EcoBank 1.0) for collecting and providing ecological information for various stake-holders. Then, we developed basic functions to analyze ecosystem for each stake-holders (researchers, general public and policy makers). We successfully designed a computing system named EcoBank supporting the functions of Digital Object Identifier (DOI) publish and data quality management.
