Abstract

This study evaluated the ecosystem services of wetlands for Duung Wetlands, Ganwol Lake, and Cheonnae Wetlands located in Chungcheongnam-do using the Wetland Ecosystem Service Brief Evaluation Method and analyzed the results separately. The evaluation method was evaluated in five stages by two local residents and two wetland experts at each target site. The evaluated results were conducted using the ESI calculation formula to analyze wetland ecosystem services, and the results are as follows. First, as a result of the final evaluation of Duwoong Wetland, experts scored 18 points and local residents 19.25 points, with a total average of 18.63 points. As a result of the final evaluation of the Cheonnae Wetland, experts scored 7.75 points and local residents 9.75 points, with a total average of 8.75 points. As a result of the final evaluation of the Ganwol Lake Wetland, the expert score was 19 points and the local residents' score was 17.5 points, with a total average of 18.25 points. Second, as a result of ESI analysis, 51.74% of Duung Wetland, 24.31% of Cheonnae Wetland, and 50.69% of Ganwolho Wetland were found. The reason why Cheonnae Wetland’s supply service score was low was that Cheonnae Wetland used to be a water source protection area, but vehicles were entering the habitat as it was released from the water source protection zone, and low evaluation results were found in the supply service sector due to indiscriminate fishing and illegal dumping. As a result of checking detailed ecosystem service items, the scores for Duung Wetland and Cheonnae Wetland were in order of supporting service > cultural service > regulation service > provisioning service. The result of the final ESI score of the Ganwol Lake Wetland was derived in the order of cultural service > regulation service > provisioning service > supporting service. As a result of this study, we conducted an evaluation of wetland behavior system service using the simplified evaluation method for three wetlands in Chungcheongnam-do, and the ESI score for each wetland was derived. At the time of evaluation, local residents said that there is a need to improve information on the simple evaluation site, and through this, it is deemed necessary to develop the Simple Evaluation Method for Wetland Ecosystem Services (RAWES) that can be easily evaluated by local residents in the future.
