摘要
在斯里兰卡西北部拉姆萨尔湿地的Anawilundawa水库发现了Eichhornia crassipes的入侵。本研究旨在确定可能导致其入侵的水质参数，并确定有效的控制措施。在2017年3月至11月的研究期间，发现石笋存在地区的Secchi深度，水深和硝酸盐含量平均值(分别为7.9 cm, 12.4 cm和475µg L-1)显著低于平均值(p
Water quality parameters contributing to the invasion of water hyacinth (Eichhornia crassipes) in the Anawilundawa reservoir in Sri Lanka
Eichhornia crassipes has been found to invade the Anawilundawa reservoir located within Ramsar wetland in the northwestern region of Sri Lanka. Present study was carried out to determine the water quality parameters that could contribute to its invasion and identify an effective control measure. During the study period of March-November 2017, mean values for Secchi depth, water depth and nitrate content in areas where E. crassipes was present (7.9 cm, 12.4 cm and 475 µg L-1 respectively) were found to be significantly lower (p
