| 摘 要： | 采用旁侧声呐、浅地层剖面仪和单波束水深测量多种物探仪器联机,同步调查天津大神堂浅海区的水下活牡蛎礁资源,为合理保护活牡蛎礁资源提供科学依据。调查结果表明,该区活牡蛎资源由3个分散礁体组成,总面积仅约3km2,礁体最大厚度1.2m,平均厚度0.6m;调查区海底地形平坦,水深介于3.4~5.6m之间,因受人类活动严重破坏,仅在有礁体发育的局部范围内有高程约1m的起伏波动。为了生态资源的完整,必须对现存的活牡蛎礁体进行保护和恢复。 |

| Abstract: | Methods of lateral scanning sonar, sub-bottom profiler and echo sounding measurer were used together to survey a living oyster reef ecology system in the shallow sea area of Dashentang in Tianjin City, which always submerge under sea water. In this paper, we aimed to provide detailed investigation data for protection of this living reefs. The investigation results show that the reefs are composed of three separated sub-reefs. The total area of the reefs is only about 3km2, with maximum thickness of 1.2m and average thickness of 0.6m. Water depth (from average sea level to the bottom) of the investigated area ranges from 3.4 to 5.6m. There is only about 1m elevation fluctuation locally in some area where there is reef surface developed. This living oyster reefs should be protected and recovered in order to keep the diversity of ecological resources. |
