  • 摘要: 为了研究水葫芦圈养对富营养化水域的影响，对星云湖14个实验区的采样点及8个对照区采样点的水质各理化性质指标、化学需氧量（COD）、生化需氧量（BOD5）、不同形态氮浓度进行测定，分析了紫根水葫芦圈养对星云湖水质的影响，结果表明：在紫根水葫芦生长发育期，星云湖中圈养的紫根水葫芦能够显著增加水体中的溶解氧含量，可以有效吸收星云湖湖水中的氨氮、总氮、总磷，降低了水体中BOD5和COD含量。总磷、总氮和氨氮三者之间显著正相关，总磷、氨氮、总氮以及BOD5都与水体的pH呈显著负相关，然而溶解氧与pH显著正相关，BOD5与水温、总磷、COD、氨氮和总氮显著正相关。科学的水葫芦圈养模式可以有效的降低富营养化水体中的营养物质，改善水质。
    Abstract: A study was conducted in 2013 to research the effects of Eichhornia crassipes on the quality of eutrophic water in Lake Xingyun. Twenty samplings were taken in the lake and we studied the temperature, pH, dissolved oxygen (DO), dissolved ammonia nitrogen (DAN), dissolved total nitrogen (DTN), dissolved total phosphorus (DTP), biochemical oxygen demand (BOD5), and chemical oxygen demand (COD). The results showed that compared with the control in Lake Xingyun, the DO of the water was significantly increased and DAN, DTN, DTP, BOD5, and COD were significantly reduced during the growth and development of Eichhornia crassipes. A significant positive correlation was shown between DTP, DTN, and DAN. A significant negative correlation was shown between pH and DTP, DAN, DTN, and BOD5. However, DO and pH were significantly positively correlated. The temperature, DTP, DAN, DTN, and CODwere significantly negatively correlated with BOD5. It can be concluded that reducing the nutrients in the eutrophic water in Lake Xingyun by using Eichhornia crassipes is most important.
