摘　　要：福建晋江深沪湾陆上古森林与海上古牡蛎礁出现于同一海滩的现象是自然界之奇观,这种现象具有重要的科学意义和研究价值,也是海洋保护管理的重要对象。自20世纪80至90年代以来,伴随深沪湾周边地区社会经济的快速发展和沿海大通道、港口、航道等基础设施建设,人类活动剧烈,而自然遗迹的保存现状亟需重新认识。本文基于多波束、单波束、浅剖、侧扫等多种地球物理手段对研究区地貌及浅地层情况进行了联合探测,并对部分可疑点进行了水下探摸。研究结果表明,调查海域主要存在海底礁石、沙波、人工构筑物、沙脊、拖痕、围网等地貌类型,人类活动痕迹剧烈,在海底未出现大规模出露的自然遗迹。通过照相、RTK等手段对出露于潮间带的古森林、古牡蛎礁等自然遗迹的分布状态进行了精细定位与描述,初步确认了19处古森林遗迹地址及数处出露古牡蛎礁遗迹分布范围。研究成果对于近海海域和海底的自然资源遗产如何开展深入调查研究具有一定的指导作用,可为自然保护区总体规划编制、明确保护区边界范围提供科学依据。It is a wonder of nature that the ancient land forest and the sea oyster reef appeared on the same beach in Shenhu Bay,Jinjiang,Fujian province.It has important scientific significance and research value,it is also an important target of marine protection and management.Since the 1980 s and 1990 s,with the rapid social and economic development and infrastructure construction of Grand Coast Freeway,ports and waterways in the surrounding areas of the Shenhu Bay,the status of nature relics needs rediscovering in intense human activities.In this paper,based on multi-beam sonar,single beam sonar,sub-bottom profile,side scan sonar,the diving and other geophysical methods,the topography and shallow strata in the study area are jointly detected,and some suspicious points are explored.The results show that there are rich submarine reefs,sand waves,sand ridges,drag marks,fishing net and other man-made obstructions in the investigated seafloor,but no large-scale exposed natural relics has been discovered in the survey.The distribution and characters of ancient submarine forest,ancient oyster reef is described based on RTK(real-time kinematic)and camara.The locations of 19 ancient forest relics and some ancient oyster reef relics are precisely confirmed.This study is important not only for guiding the investigation of the natural relics in offshore and costal,but also providing a scientific basis for the master planning of the nature reserve and the boundary of the nature reserve.
