Abstract

Marine spatial planning(MSP) designates the marine as nine kinds of use zones for the systematic and rational management of marine spaces. One of them is the fishery protection zone, which is necessary for the sustainable production of fishery products, including the protection and fosterage of fishing activities. This study intends to quantitatively identify the fishing activity space, one of the elements necessary for the designation of fisheries protection zones, by mapping of fishery activities using V-Pass data and deriving the fishery activity concentrated zone. To this end, pre-processing of V-Pass data was performed, such as constructing a dataset that combines static and dynamic information, calculating the speed of fishing vessels, extracting fishing activity points, and removing data in non-fishing activity zone. Finally, using the selected V-Pass point data, a fishery activity map was made by kernel density estimation, and the concentrated space of fishery activity was analyzed. In addition, it was confirmed that there is a difference in the spatial distribution of fishing activities according to the type of fishing vessel and the season. The pre-processing technique of large volume V-Pass data and the mapping method of fishing activities performed through this study are expected to contribute to the study of spatial characteristics evaluation of fishing activities in the future.

해양공간계획은 해양을 체계적이고 합리적으로 관리하기 위해 9가지 용도구역으로 지정한다. 그 중 하나가 어업활동의 보호와 육성을 비롯한 수산물의 지속 가능한 생산을 위해 필요한 어업활동 보호구역이다. 본 연구는 V-Pass 자료를 활용하여 어업활동 지도를 제작하고 어업활동 밀집 공간을 도출함으로써 어업활동보호구역 지정에 필요한 요소 중 하나인 어업활동 공간을 정량적으로 파악하고자 한다. 이를 위해 V-Pass 자료를 정적 정보와 동적 정보가 결합된 데이터셋 구축, 어선 속도 계산, 어업활동 지점 추출, 비어업활동 공간 내의 자료 제거와 같은 전처리를 수행하였다. 최종적으로 선별된 V-Pass 점 자료를 이용하여 커널밀도추정으로 어업활동 지도를 제작하고 어업활동이 밀집된 공간을 분석하였다. 또한 어선의 업종과 계절에 따라 어업활동의 공간분포는 차이가 있음을 확인하였다. 본 연구를 통해 수행한 대용량 V-Pass 자료의 전처리 기법과 어업활동의 공간밀도 분석 방법은 향후 어업활동에 대한 공간특성평가 연구에 기여할 것으로 기대된다.
