星云湖隔河湖湾飘浮植物除藻技术研究

Research on Technology of Removing the Algae by Floating Vegetation in Gehe River Bay of Xingyun Lake

在星云湖隔河口湖湾围养20万m^2水葫芦去除蓝藻，经两年的研究结果表明：蓝藻去除率在80％以上，透明度提高到1．5—2m，河道沉水植物恢复良好，水质从劣Ⅴ类恢复到Ⅲ-Ⅳ类。

Through two - year study on technology of removing the algae by floating vegetation in Gehe river bay of Xingyun lake by planting 200, 000 square meters common waterhyacinthes, the results show that remove rate of blue algae is above 80 percent, the limpidity is improved to 1.5 to 2 meters, the restore of submergent plant is good, and the water quality is promoted from the fifth class to the third or the fourth class.
