摘要
本文报道了长江中游开敞式天鹅洲故道和封闭式老河故道浮游植物、浮游动物、底栖动物及水生维管束植物四大类水生生物多样性的异同和变化。浮游植物、浮游动物和水生维管束植物的多样性都是老河故道高于天鹅洲故道，底栖动物的多样性则是天鹅洲故道高于老河故道。预期随着天鹅洲故道由开敞式向封闭式的演变。
his paper reports the diversity of phytoplankton, zooplankton, zoobenthon and aquatic macrophytes in Tiane Zhou Oxbow and Laohe Oxbow located at the middle reaches of Yangtze River. The diversity of phytoplankton, zooplankton and aquatic macrophytes in Laohe Oxbow is higher than that in Tiane Zhou Oxbow, the diversity of zoobenthon in Laohe Oxbow is lower than that in Tiane Zhou Oxbow. Along with change from opening to closing of oxbow, the diversity of aquatic organisms in Tiane Zhou Oxbow will be on the increase.
