Abstract

This study is conducted for analysis of distribution of macrobenthic by using satellite image and in-situ data in the intertidal zone of Suncheon bay. The satellite images on low tide on July 7, 2010 and high tide on Sept. 25, 2010, respectively, are classified into sea water, tidal flat and land. It is to extract for intertidal zone overlaying at low tide and high tide image from previously classified image. Total number of species emergence are 196 species in the intertidal zone, and most species are emergence in the right part of the subtidal zone. The Sigambra tentaculata is the dominant species and emergence the Mediomastus californiensis, Magelona japonica, etc. It is noticed that many kind of macrobenthic distribution in the subtidal zone more than the supralittoral zone. It find out that contamination due to organic through the macrobenthic distribution with a strong resistance to organic in the subtidal zone of Suncheon Bay.

본 연구는 위성영상과 현장자료를 이용하여 순천만 조간대의 대형저서생물의 분포를 분석하기 위하여 수행되었다. 2010년 7월 7일 간조에 근접한 위성영상과 2010년 9월 25일 만조에 근접한 위성영상을 무감독분류를 이용하여 바다와 갯벌, 육지로 분류하였다. 분류된 영상에서 간조 때와 만조 때의 갯벌을 중첩시켜 조간대를 추출하였다. 조간대에서 총 출현 수는 196종이었으며 조하대 우측에서 가장 많은 종이 출현하였다. 투구갯지렁이류(Sigambra tentaculata)가 가장 우점 하였으며 버들갯지렁이류(Mediomastus californiensis, Heteromastus filiformis), 양손갯지렁이(Magelona japonica) 등이 출현하였다. 조상대에 비해 조하대에 많은 저서생물들이 분포하는 것을 파악하였다. 유기물에 강한 내성을 지닌 대형저서생물들의 분포를 통해 순천만 조하대 지역이 유기물로 인하여 오염 되었다고 판단된다.
