Abstract

This study was carried out to offer basic data to minimize the indiscreet development and damage of coastal wetlands through an evaluation from an ecological standpoint highlighting the importance of the coastal wetland in South Gyeongsang Province, Korea. The result of the macrobenthos survey for the coastal wetland assessment showed that Dongdal and Hwasan-ri, Yongnam-myeon, and Tongyeong city had the largest species number; Oegan-ri and Naegan-ri, Geoje-myeon, and Geoje city had the largest population and biomass; and Miryong-ri, Samsan-myeon, Goseong-gun had the highest species diversity. In the halophytes survey, Imyeong-ri, Jinjeon-myeon, Masan city and Oegan-ri and Naegan-ri, Geoje-myeon, Geoje city had the large character species and companion species. The evaluation results of the ecological values of the coastal wetlands were categorized into five grades based on the field surveys, and the sedimentary environment factor in the case of Danghang-ri, Hoehwa-myeon, and Goseong-gun; Miryong-ri, Samsan-myeon, Goseong-gun; Guho-ri, Gonyang-myeon, Sacheon city; Sulsang-ri Yangpo-ri, Jingyo-myeon, Hadong-gun; and Seokpyeong-ri, Idong-myeon, Namhae-gun, were appraised at the highest rating of grade II. The halophytes factor in the case of Imyeong-ri, Jinjeon-myeon, Masan city, Dongdal-ri and Hwasan-ri, Yongnam-myeon, Tongyeong city and Oegan-ri and Naegan-ri, Geoje-myeon, Geoje city, were highly evaluated as grade II. The macrobenthos factor in the case of Imyeong-ri, Jinjeon-myeon, Masan city and Oegan-ri and Naegan-ri, Geoje-myeon, Geoje city was highly evaluated as grade II. The final evaluation grade was calculated by the mean values of three evaluation factors, and Imyeong-ri, Jinjeon-myeon, Masan city and Oegan-ri and Naegan-ri, Geoje-myeon, and Geoje city had the highest rating of II. On the other hand, Seokpyeong-ri, Idong-myeon, Namhae-gun had the lowest rating of IV. These locations will require future research to survey and monitor the coastal wetland ecosystems by season, in addition to the construction of the GIS-based wetland information system with a view to manage the coastal wetlands.

본 연구는 경상남도의 중요한 연안습지를 대상으로 생태적 측면에서의 가치평가를 실시하여 연안습지의 무분별한 개발과 훼손을 최소화 하기 위한 기초자료를 제공하고자 수행하였다. 연안습지 평가를 위한 현지조사 결과, 저서생물은 통영시 용남면 동달리, 화삼리의 종수가 가장 많았고 거제시 거제면 외간리, 내간리 일대는 개체수와 생체량이 가장 많았다. 종다양성지수는 고성군 삼산면 미룡리가 가장 높게 나타났다. 염생식물의 표징종과 수반종이 가장 많이 출현한 지역은 마산시 진전면 이명리와 거제시 거제면 외간리, 내간리로 조사되었다. 이러한 현지조사 결과를 토대로 연안습지의 생태적 가치를 5개 등급으로 평가한 결과, 퇴적환경은 고성군 회화면 당항리, 고성군 삼산면 미룡리, 사천시 곤양면 구호리, 하동군 진교면 술상리, 남해군 이동면 석평리가 II등급으로 가장 높게 평가되었다. 저서생물은 마산시 진전면 이명리, 통영시 용남면 동달리, 거제시 거제면 외간리, 내간리가 II등급, 염생식물은 마산시 진전면 이명리와 거제시 거제면 외간리, 내간리가 II등급으로 가장 높게 평가되었다. 평가요인별 평균값을 기준으로 한 최종적인 평가등급은 마산시 진전면 이명리, 거제시 거제면 외간리, 내간리가 가장 높은 II등급으로 나타났고 남해군 이동면 석평리가 IV등급으로 가장 낮았다. 향후 연안습지 생태계의 지속적인 조사와 장기적인 모니터링, 그리 연안습지를 체계적으로 관리하기 위한 GIS기반 연안습지정보시스템 구축을 위한 연구가 필요할 것으로 사료된다.
