제주도 사계 해안사구식생의 군락분류를 통한 생태교육자료 개발

Abstract

This study was conducted to classify communities based on vegetation types distributed in Sagye coastal sand dunes in Seogwipo city, Jeju Special Self-Governing Province, the southernmost part of Korea, and to develop related educational materials. The field vegetation survey was conducted for approximately 2 years, from April 2020 to October 2021 with the Z.-M method emphasizing plant sociological species composition and habitat homogeneity. Through the survey, we obtained 190 vegetation data and analyzed the behavioral patterns of a total of 141 plant taxa using 9 levels of converted integrated dominance and relative contribution (r-NCD). Vegetation types were broadly classified into three correlated categories: herb communities on dunes, shrub communities on dunes, and artificial afforestation vegetation. As a result of community classification, 19 units of vegetation were identified, comprising a total of 6 associations and 13 communities. The representative communities were the Vitex rotundifolia community, which is coastal dune shrub vegetation, and the Pinus thunbergii community, which is arboreal vegetation. In the evaluation of vegetation naturalness, the [Ⅱ] grade was high with 7 communities, accounting for 36.8% of the total community, and the [Ⅲ] grade was 9 communities, accounting for 47.46% of the total community. Vegetation naturalness grade [Ⅱ] areas are defined as vegetation that is selectively and strictly required for ecological conservation activities, so conservation measures for this vegetation are considered necessary. This research data is expected to be widely used by teachers in developing field ecological education materials, as well as ecological learning education materials, by providing ecological-based vegetation data by establishing a community classification and community system for existing vegetation.
