Abstract

Recently, wetland and paddy wetland are being highlighted as the international environmental issues. However, research system which can assess paddy wetland is lacking. Thus, the purpose of this study is to assess the value of paddy wetland by applying RAM to paddy wetland. In addition, we would like to use this study as the data to establish assessment method for paddy wetland. 16 sites were selected as research targets based on altitude and soil. As the results of wetland assessment, 16 research target sites had total score of 212~227 and the average of 2.17~2.50. It was similar to those of Lacustrine Wetlands, Palustrine Wetland and Riverine Wetland which were sites in previous studies. The value could be recognized as the wetland. However, there was no difference in assessment results based on altitude and soil. It was found that all conservation values were the same. The factor the most closely affecting conservation value was the area. However, there was limitation to apply existing wetland assessment system to paddy wetland. In order to assess paddy wetland, factors such as rice farming methods, topography, vegetation, growth environment and biodiversity should be added. It was thought to supplement wetland assessment system through various further studies.

최근들어 세계환경의 화두는 습지와 더불어 논습지 그리고 습지의 생태계서비스 기능에 집중 조명되고 있지만, 논습지의 생태계서비스를 평가 할 수 있는 연구체계가 부족한 실정이다. 따라서 본 연구는 기존의 습지평가체계를 논습지에 적용하여 습지로서 논의 가치를 평가해보는 동시에 논습지 중심의 평가체계를 구축하는 기초자료로 활용하고자 연구를 진행하였다. 연구 대상지는 고도와 토양을 기준으로 16곳을 선정하였다. 습지평가 결과 연구대상지 16곳은 총점 110점~118점, 평균 2.17~2.50으로 선행연구 사례지인 호수형습지, 소택형습지, 하천형습지와 비교해도 습지로서 가치가 인정되었다고 할 수 있다. 하지만 고도, 토성에 따라서는 평가결과의 차이는 없었으며, 보전가치는 모두 같게 나타났다. Pearson 상관분석을 통해 보전가치에 가장 밀접하게 작용하는 요인을 찾아본 결과, 면적이 상관관계가 있는 것으로 나타났다. 그러나 기존의 습지평가체계로 논습지에 적용하기에는 한계가 있는 것으로 사료되어 논습지 평가를 위해서는 재배유형, 지형적 특성, 식생특성, 생육환경, 생물다양성 등의 다양한 후속 연구를 통해 습지평가체계를 보완할 필요가 있는 것으로 판단하였다.
