| 摘 要： | 黄河口海域大型底栖生物群落结构受到包括自然和人为在内的诸多因子的影响，本次研究以2011年调水调沙活动对该海域大型底栖生物群落结构的影响研究为主，分析其短期内群落结构的变化。调水调沙前、中、后期均采用同样的站位取样，分别为1～18号站位，按照距离黄河入海口的距离分为4个梯级，为5、10、20和40km。研究结果显示：调水调沙前、中、后期分别渔获大型底栖生物73,72和85种，重要种的数量分别为13,1和16种；所有种类可以统计为4个门类，为环节动物、软体动物、节肢动物和棘皮动物，其中，环节动物和软体动物占比重最大，而1982年其他学者对莱州湾大型底栖生物的研究显示，棘皮动物和环节动物占比重最大，这表明近30年该海域大型底栖生物的群落结构产生较大变化；BOPA指数显示，前期各站位水质较高，中期和后期分别有2,3个站位受到中等程度污染；ABC曲线分析说明，调水调沙中、后期，大型底栖生物群落受扰动较大；群落聚类分析和冗余分析（RDA）表明，大型底栖生物群落结构与环境因子关系密切，其中，调水调沙中期有机物对群落结构的影响最大，而后期的较大影响因子为水深。环境因子并不是单一作用于生物群落，而是几个环境因子共同作用，包括有机物、硫化物、重金属Hg和As等；不同环境因子造成群落结构变动的原因较多，其一可能是海水透明度的下降造成大型底栖生物的生长和繁殖受阻。本次研究重点表明，人类多元活动从短期和长期看对大型底栖生物的群落结构变动影响均较大，调水调沙活动对黄河口海域大型底栖生物的栖息地作用明显，改变其水温、盐度、群落扰动等。因此，应当加强对该海域入海陆源污染物的控制，加强对海洋生态平衡的保护。

| Abstract: | The community characteristics of macrobenthos in the Huanghe (Yellow River) Estuary is influenced by a combination of natural and anthropogenic factors. Here, we investigated short-term changes (1-month) in macrobenthic community structure in response to water and sediment discharge regulation (WSDR) in 2011. Specifically, we sampled the macrobenthos at 18 sampling stations situated at four distances (5, 10, 20, and 40 km) from the mouth of the Huanghe Estuary before (mid-June), during (early-July), and after (mid-July) WSDR. The results showed that a total of 73, 72, and 85 species were collected before, during, and after WSDR, respectively. Then, 13, 1, and 16 dominant species were detected at this three periods. Four phyla were primarily detected at all three periods (Annelida, Mollusca, Arthropoda, and Echinodermata). However, while Mollusca and Annelida were the most important phyla in our study, Echinodermata and Annelida were the most important phyla in 1982, demonstrating major changes to community structure over a 3-decadal period. All stations were of high quality BOPA index before WSDR, whereas two and three stations were of reduced quality BOPA index during and after WSDR, respectively. The results of ABC curves showed that had incurred disturbed conditions after human activities WSDR. Most important of all, multivariate analyses and RDA analysis indicated that the structure of the macrobenthic community was closely linked to environment factors, including that organic content factor caused the distribution of macrobenthic community mostly during WSDR, while water depth after WSDR affected the macro benthos community structure seriously, and during WSDR, the environment factor influencing it was not single, including organic content, sulfide content, Hg and As. These differences may have been due to changes in water transparency negatively impacting the growth and development of macrobenthos, due to specific lifehistory requirements. Our results demonstrate that anthropogenic activity is having both long-term (3 decadal) and short term (1-month) impacts on the structure of the macrobenthic community of the Huanghe Estuary. In conclusion, human activities WSDR influence the habitat environment of macro benthos, including the water temperature, nutrients, bioturbation, and so on. Therefore, we suggest the necessity to strengthen regulations of land-derived organic pollutant input to maintain the ecological balance of the Huanghe Estuary. |
