  • 摘要: 为了探讨大水域种养水葫芦对滇池湖湾水质的影响,于2010年8—10月对滇池白山湾约70 hm2水葫芦种养区域的水质特征进行动态监测。结果表明,水葫芦区水体中总磷、总氮及高锰酸钾指数从9月中旬后开始逐步上升。水葫芦区水体溶解氧、pH较近水葫芦区和远水葫芦区显著降低,但水葫芦区溶解氧仍维持在较高水平;总磷、总氮及高锰酸钾指数较近水葫芦区和远水葫芦区显著升高;在水葫芦周围水体(近水葫芦区)水质得到明显改善,表现为水体透明度显著高于水葫芦区及远水葫芦区,总磷、正磷酸盐、总氮及叶绿素a明显低于水葫芦区及远水葫芦区。
    Abstract: To evaluate the effects of large-area planting water hyacinth (Eichhornia crassipes) on water quality in the bay of Lake Dianchi, consecutive water sampling investigations in the planting, near-planting and far-planting areas of water hyacinth were carried out from August to October 2010. Results showed that total phosphorus, total nitrogen and permanganate index in the water of the planting areas increased since mid-September. Compared with near-planting and far-planting areas, dissolve oxygen and pH in planting area significant decreased, but the dissolved oxygen remained at high levels; however, total phosphorus, total nitrogen and permanganate index obviously increased. The water transparency in the near-planting area was higher than those in the planting and far-planting areas, and total phosphorus, orthophosphate, total nitrogen and chlorophyll-a were lower than those in the planting and far-planting areas, showing that the water quality was improved in the near-planting area.
