摘要:

以2005 年7～9 月辽东湾浮游动物的调查数据为主, 并结合以往的调查数据对浮游动物的种群结构、分布特征、多样性指数的变化及其与海洋环境因子的关系进行了分析。结果表明, 辽东湾浮游动物个体数量主要集中在北部海区, 而其生物多样性与均匀度指数却明显低于西部和东南部海区, 说明该海区水体、生态环境、生物群落不如西部和东南部海区稳定、成熟。浮游动物多样性主要受透明度(r_H′ = 0.599＞r_0.01; r_E = 0.322＞r_0.05, n = 40)、水温(r_H′ = 0.469＞r_0.01, r_E = 0.432＞r_0.01, n = 40)、COD(r_H′= ?0.389＞r_0.05; r_E = ?0.217＜r_0.05, n = 40)、W(r_H′ = ?0.461＞r_0.01; r_E = ?0.417＞r_0.01, n = 40)、物种数(r_H′= 0.835＞r_0.01; r_E = 0.653＞r_0.01, n = 40)影响较大。

Abstract:

Based on the data of surface zooplankton obtained in the north waters of Liaodong Bay in 2005,this paper analyzed the composition, distribution, diversity index of surface zooplankton and their correlations with environmental factors. It was found that the zooplankton in the Liaodong Bay was centralized in the north sea area, and the indices of diversity and equality in the north were lower than those of the west and the southeast. indicating that the water entironment and biology community in the north were not steady. The phytoplankton diversity was restricted by environment factors such as diaphaneity(r_H′ = 0.599＞r_0.01; r_E = 0.322＞r_0.05, n = 40), water T(r_H′ = 0.469＞r_0.01, r_E = 0.432＞r_0.01, n = 40), COD(r_H′= ?0.389＞r_0.05; r_E = ?0.217＜r_0.05, n = 40),W(r_H′ = ?0.461＞r_0.01; r_E= ?0.417＞r_0.01, n = 40), s(r_H′= 0.835＞r_0.01; r_E = 0.653＞r_0.01, n = 40).
