| 摘 要： | 通过单独与混合培养实验,结果显示在适宜营养水平下,水网藻对氮、磷有较强的富集吸收能力;而来自微藻生长竞争的压力会促使水网藻对营养物的生态幅变窄,满足其最佳生长所需要的PO43-P从0.085mg/L降低为0.024mg/L;并且其富集磷的能力也大为降低。在利用水网藻进行富营养化水体修复或净化水质时,这种生物之间的抑制现象必须引起重视。 |

| Abstract: | This paper relates to pure and mixed cultures of Hyd-rodictyon reticulatum and micro-algae. Though Hydrodictyonreticulatum has a strong ability to absorb and store nitrogenand phosphorus under proper condition, its ecological breadthor its ability to accumulate TN and TP rather decrease due tothe resource competition of micro-algae. This phenomenon isworth attention when ecological restoration is conducted usingHydrodictyon reticulatum. |
| Keywords: | H reticulatum micro-algae resource competition stress ecological restoration |
