为治理三峡水库蓄水后支流库湾的水华，在三峡水库典型次级支流高岚河进行了机械、植物药剂、生物操纵和生态调度控制藻类水华的相关试验，结果表明：利用特制的机械设备和植物药剂可以在一定程度上控制藻类水华的发生和发展，可以用于对藻类水华的应急处置；放流鲢鱼的非经典生物操纵技术对水华具有较好的抑制作用，达到了水环境保护和渔民增收的双重目的；生态调度能够改变水体的水动力学环境，能在一定程度上控制藻类水华。

In order to control the algal bloom in branch bays of Yangtze river after the impoundment of Three Gorges res -ervoir , experiments are conducted on algal bloom controlling in Gaolanhe river , a typical secondary tributary of the Three Gorges reservoir .Mechanical , botanical , bio-manipulation techniques and ecological operations are adopted in the ex-periments .Results show that the occurrence and development of algal bloom can be controlled , to some extent , by spe-cialized machinery and botanical agent , which can be adopted as emergency treatment measures .While a non-traditional bio-manipulation technique , silver carp releasing , achieves good restraint effect upon algal bloom .And a comprehensive benefit is obtained in both the water environment protection and economical profits of the fishermen .Ecological operation is also able to control the algal bloom by changing hydrodynamic environment .
