“引江济淮”输水干线浮游藻类与水体质量研究

Study of the floating algae and water quality of the main line in the diversion of water from Changjiang River to Huaihe River

拟议中的"引江济淮"工程是一项涉及长江、淮河两大河流的跨流域的调水工程,在对"引江济淮"项目区主要水体调查的基础上,讨论了水体质量以及浮游藻类种类组成与数量以及藻类对水体质量的指示作用。研究表明,巢湖与瓦埠湖及输水河流之间藻类结构具较高的相似性,两湖泊为中或富营养化型湖泊。单纯的输水可能不会改善巢湖和瓦埠湖的水质,应辅以污染的综合治理措施,恢复湖泊的正常生态过程。

The recommended project of diversion of water from Changjiang River to Huaihe River is a water allocation programme which involves both Changjiang River and Huaihe River. In this paper,an investigation of the main water body in the project region is made, then the water quality is analyzed,and the composition and quantity of floating algae are described,and the indication function of the algae to the water quality is discussed. There is high similarity in algae structure between Chaohu Lake and Wabuhu Lake and among the related rivers,the two lakes are eutrophication lakes,and the water body in the region is at middle degree of pollution. It is not sure that watertransfer will make the water quality of Chaohu Lake and Wabuhu Lake better simply,so comprehensive treatment measures should be adopted to recover the normal ecoprocess in the lakes.
