생태⋅자연도 등급변화에 영향을 미치는 요인 분석 -경상남도 일대를 대상으로-

Abstract

In this study, we used the ecology and nature map of March 2021 and the ecology and nature map of May 2023 to analyze the pattern of grade change and factors of grade change by period in the Gyeongsangnam-do area. As a result of the analysis, the area of ecology and nature map in the study area decreased by 1.7% in the 1st grade area, increased by 0.5% in the 2nd grade area, increased by 1.1% in the 3rd grade area, and increased by 0.2% in the separately managed zones in 2023 compared to 2021. The factors contributing to the increase in ecology and nature map ratings include improved precision in vegetation surveys, advancement of survey techniques for endangered wildlife, and increased survey points. In addition, it was found that wetland survey data increased, habitat quality improved, and landform survey data was accumulated. Among them, the improvement of survey techniques through the introduction of the latest equipment and the discovery of previously undiscovered ecology and nature map 1st grade area evaluation factors served as a factor in raising the grade. Meanwhile, the factors that led to the decline in the ecology and nature map grades were revision of the ecology and nature map drawing guidelines, update of the endangered wildlife database, adjustment of forest and wetland boundaries due to reflection of the latest land cover map and forest type map, and increase in deforestation areas. The derived results can be used as basic data for expanding and maintaining protected areas in accordance with international action goals, and are expected to be helpful in establishing improvement plans for the creation and use of ecological and nature maps.
