糖厂废水对博斯腾湖藻类影响研究

Investigation of the Effect of Wastewater from Sugar Factory on the Algae in Lake Bosten

采用围隔式生态系现场模拟糖厂生产废水排放对博斯腾湖藻类种群结构和生长的影响，结果表明，藻类种群结构和生物量均会受到影响，藻类种群数随废水浓度提高而趋于减少，藻类优势种发生变化，低浓度废水会促进藻类生长，高浓度废水则会抑制藻类生长，结论是糖厂废水排放对博斯腾湖藻类种群结构和生长存在影响。

In-Site ecological enclosure system was used to simulate the effect of wastewater from sugar factory on the species structure and growth of algae in Lake Bosten.The result showed that both the algae species structure and biomass were affected:the algae species group number reduced and the dominant algae species changed with the increase of wastewater concentration.Low concentration wastewater accelerated the alga growth while high concentration wastewater restrained the alga growth.The result is that wastewater discharge will affect thd algae species structure and their growth in Lake Bosten
