摘要

摘要: 由于人类活动在长江河口的干扰,河口生态系统在最近几十年已经出现急剧的变化。本文基于长江河口自1998-2012年连续测量且涉及生态系统的指标最新数据,对流域及其河口人类活动影响长江河口生态系统的变化进行研究。主要结果包括:河口浮游生物在观测期间有明显的减少,经济鱼类如刀鲚和凤鲚的年产量亦出现减少趋势。此外,河口底栖生物的种类和生物量在2003年前后各自展示了向下和向上的波动趋势。中华绒螯蟹则在总产量上呈现升高的趋势,几乎增加了97%的产量。研究表明进入河口营养盐要素尤其是溶解硅的减少对于河口硅藻种类的降低具有重要影响。深水航道的挖掘和抛泥则引起了航道浮游生物的减少。然而,人工繁殖和放流则对生态系统的恢复有明显促进作用,譬如中华绒螯蟹产量的增加,底栖生物的生物量和种类的增加。

Abstract: Estuarine ecosystem has greatly changed in the recent decades due to anthropogenic perturbations in the Changjiang Estuary. Change patterns and impact factors were analyzed based on the continuous data in relation to the Changjiang estuarine ecosystem from 1998 to 2012. The results showed significant decreases in plankton species and annual output of Coilia nasus, Coilia mystus. Furthermore, species and biomass of benthos showed abrupt change in 2003, downward before that and upward after that. It was noted that, Eriocheir sinensis, a high value commercial fish, had an annual production increase of 97%. Reduction of riverine nutrients, especially dissolved silicate (DSI) loads into the estuary could contribute to the decline in Bacillariophyta species. Dredging and dumping works of the North Passage led to the decreases in regional plankton species. However, the species reproduction and releasing projects could restore the estuarine ecosystem through increasing the output of E. sinensis, as well as species and biomass of benthos.
