塘沽潮间带大型底栖动物调查及群落结构分析

分析和报道了天津塘沽海区潮间带大型底栖动物群落结构的水平格局和垂直格局,结果表明:绝大部分生物种类在水平格局上明显的成群分布.垂直格局中,甲壳类和织纹螺占据了表层空间;表层至15 cm范围栖息着双壳类、腕足类和巢沙蚕等;更深范围是四角蛤蜊为主的双壳类以及长吻沙蚕为主的多毛类.由此及群落结构变得单一的现状,从空间生态位的角度进行了生物修复的一些探讨,列举了青蛤、毛蚶、双齿围沙蚕等一些适宜移植的种类.

Investigation and Structure Analysis of Macrobenthos Community in Tanggu Intertidal Zone

An investigation of Macrobenthos of intertidal zone was reported in this paper, which was carried out in Tanggu district, Tianjin city during June 2003.Based on this, Horizontal and vertical structures of the community were analyzed.On one hand,absolute majority of Macrobenthos distributed in group for horizontal structure. On the other hand, there were more crustacean and Nassarius on the surface of the investigational zone; more bivalve, Lingula anatina, and Diopatra neapolitana existed from surface to 15 cm deep. Bivalve (mainly Mactra veneriformis) and polychaeta (mainly Glycera chirori) lived more deeply. On the space niche theory, some advices and methods for bioremediation, such as transplanting some Macrobenthos, were also put forward in this paper.
