Abstract

Recent interest in geological heritage has been increased in that it can be used as a basic data onto predicting the global environmental change of its containing information about past global environment. In addition, due to the characteristics of the geological heritage, it is easy to damage and difficult to recover without continuous preservation and management. However, there are more damages occurring because of the sporadic spatial distribution and ambiguous management authority of geological heritage. Therefore, an integrated management system is needed by determining the spatial distribution of geological heritage preferentially. In this study, the detailed criteria for assessment of value from the preliminary studies were applied and the geological heritage grade distribution map was generated by using geospatial data in Seoul metropolitan area. For this purpose, the list of geological heritage sites in the Seoul metropolitan area, which is the study area, were complied through a literature review. The geospatial database was designed and constructed by applying the detailed criteria for assessment of value from the preliminary studies. After the construction of the spatial database, a grade map of the geological heritage was created. As a result of the geological heritage grade map in the Seoul metropolitan area, there were more than 35% of the geological heritage in northern Gyeonggi provinces such as Yeoncheon city (18.8%), Pocheon city (10.6%) and Paju city (6.3%). It is followed by 18.1% in Incheon and 8.1% in Ansan, which is approximately 26.2% in western Gyeonggi Province. The geological age of the geological heritage was the highest at in the fourth stage of the Cenozoic era of 16.9%. Through the results of this study, the geological heritage data of the Seoul metropolitan area were extracted from existing literature data and converted into spatial information. It enables comparing the geological features with the spatial distribution of geological heritage. In addition, a management system has been established based on spatial information of constantly building geological heritage data. This provides the integrated management system of the geological heritage to manage authority so that it can be used as a basis for the development of the geological park. Based on the results of this study, it is considered to be possible to systematically construct and utilize the geological heritage across the country.

과거 지구 환경에 대한 정보를 바탕으로, 향후 지구 환경 변화를 예측할 수 있는 기초자료로 활용할 수 있다는 점에서 최근 지질유산에 대한 관심이 증가하고 있다. 또한 지질유산의 특성상 지속적으로 보존 및 관리를 하지 않으면 훼손이 쉽고 복구가 어렵다. 그러나 현실적으로 지질유산이 공간적으로 다양하게 분포하고 실질적인 지질유산의 관리주체가 명확하지 않기 때문에 많은 훼손이 발생하고 있다. 지질유산의 공간적인 분포를 우선적으로 파악하여 지질유산의 통합적인 관리체계를 구축하여야 한다. 본 연구에서는 선행연구에서 마련된 지질유산에 대한 가치평가 기준을 통해 공간정보를 이용하여 수도권 지역의 실제적인 지질유산 등급분포도를 작성하였다. 이를 위해 우선적으로 문헌조사를 통해 연구지역인 수도권 일대의 지질유산 현황목록을 정리하였고, 선행연구를 통해 마련된 가치평가 기준을 적용한 데이터베이스를 설계 및 구축하였다. 설계된 항목을 통해 공간정보 데이터베이스를 구축한 후 지도화하는 과정을 통해 지질유산 등급분포도를 작성하였다. 지질유산 등급분포도 작성 결과 수도권 지역의 지질유산은 경기도 연천시(18.8%), 포천시(10.6%), 파주시(6.3%) 등 경기북부지역에 약 35% 이상이 존재하였으며, 인천광역시에 18.1%, 경기도 안산시 8.1%로 경기서부지역에 약 26.2%가 존재하였다. 지질유산의 지질시대는 신생대 제 4기가 16.9%로 가장 높게 나타났다. 이러한 연구결과를 통하여 지질유산의 공간 분포적 특성과 함께 지질학적 특성을 분석할 수 있도록 한다. 또한 지속적으로 구축되고 있는 지질유산 데이터를 공간정보를 기반으로 관리할 수 있는 체계가 수립될 수 있다. 이를 통해 지질유산에 대한 정보가 공간적으로 통합 관리 될 수 있으며 관리 주체가 지질유산에 대한 명확한 정보를 통해 지질공원으로의 발전에 활용할 수 있을 것이다. 본 연구 결과를 바탕으로 추후에는 수도권 지역 뿐 아니라 전국적으로 확대하여 지질유산의 체계적인 구축 및 활용이 가능할 것으로 사료된다.
