The diversity of LH08 station was the lowest, and the diversity difference of every station was significant. The analysis on species diversity index and advantage curve showed that community structure of zoobenthos on every station was less effected, indicating that the sea area was on mild artificial disturbance status.

位于港池的LH08站多样性最低，各站位的多样性差异显著；物种多样性指数和K-优势曲线的分析显示，各站位的底栖动物群落结构没有受到较大影响，表明该海域处于轻度人为扰动的状态。
