Abstract

The purpose of this study is to construct a GIS / DB by grasping a small but ecologically valuable village wetland distribution, and to propose conservation management and wise use plan. The study area is Seocheon-gun, a typical farming village. Firstly, based on the digital topographical map (1:5,000), the Arc-GIS tool was used to identify the provisional(draft) village wetlands. In addition, for the management of village wetlands, wetlands with an area of more or less than $625m^2$ each were derived and according to ecological regions study area was classified into urban areas, inland areas and coastal areas. And finally, according to the wetland identifying indicators, the village wetlands were identified as the final village wetlands through indoor and field trips. The results of the study show that there are 570 village wetlands in Seocheon - gun province, which are 74 in urban areas, 220 in inland areas, and 276 in coastal areas. The case study for village wetland identification was conducted in one out of two urban areas (Seocheon - eup), two of four coastal areas (Biin - myeon and Seo - myeon), and three of seven inland areas (Masan - myeon, Hansan - myeon, and Sicho - myeon). The distribution of village wetlands was found mainly to be a village wetland with an area of less than $625m^2$. In addition, compared with inland areas, the discrimination rate of village wetlands in coastal areas and urban areas was relatively low, indicating that inland areas were still less disturbed, and land use in urban areas and coastal areas is changing rapidly. Especially, land with less awareness such as village wetlands is relatively easily damaged, and management strategy is urgent.

본 연구는 작지만 생태적으로 가치있는 마을습지 분포를 파악하여 GIS/DB를 구축하고 보전 관리 및 현명한 이용 방안을 제시하는데 목적이 있다. 연구대상지는 전형적인 농어촌마을인 서천군으로서, 먼저 수치지형도(1:5,000)를 바탕으로 Arc-GIS를 이용하여 마을습지 가능지를 파악하였다. 또한 마을습지 관리를 위해 면적 $625m^2$ 이상인 습지와 미만인 습지로 구분하여 각각 도출하였으며, 생태권역에 따라 도심지역, 내륙지역, 해안지역으로 구분하였다. 이렇게 조사된 마을습지 가능지를 습지판별 지표에 따라 실내조사 및 현장답사를 통해 최종 마을습지로 판별하였다. 연구결과 도출된 서천군 마을습지 가능지는 570개소로서, 이를 생태권역으로 구분하면 도심지역 74개소, 내륙지역 220개소, 해안지역 276개소 등으로 나타났다. 습지판별 사례연구는 각 생태권역별로 도심지역 2개읍 중 1개읍(서천읍), 해안지역 4개면 중 2개면(비인면, 서면), 내륙지역 7개면 중 3개면(마산면, 한산면, 시초면)을 대상으로 하였다. 마을습지 분포는 면적 $625m^2$ 미만의 마을습지가 대부분으로서 소규모 마을습지에 대한 체계적 관리전략이 필요함을 알 수 있었다. 또한 내륙지역에 비해 해안지역이나 도심지역의 마을습지 판별율이 상대적으로 낮게 나타났는데 이는 내륙지역이 아직 덜 교란되었음을 말해주고 있고, 상대적으로 도심지역과 해안지역 토지이용이 빠르게 변화하고 있으며 특히 마을습지와 같이 중요성이 덜 인식된 토지들이 비교적 쉽게 훼손되고 있어 관리전략이 시급함을 알 수 있었다.
