狐尾草

This study tried to select potentially the most aggressive species in hope of facilitating the making and the assessment of future conservation strategies. They include terrestrial species of Bidens pilosa var. radiata, Imperata cylindrical var. major, Brachiaria mutica, Paspalum distichum, Leucaena leucocephala and aquatic species of Egeria densa, Myriophyllum aqualicum, Eichhornia crassipes, Pistia stratiotes, Alternanthera philoxeroides.

本研究提出最具入侵潜力的外来植物，以作为未来保育策略之评估指标，主要有大花咸丰草、白茅、巴拉草、双穗雀稗、银合欢、水蕴草、粉绿狐尾藻、布袋莲、大萍、空心莲子草等。

Different submerged plant communities had indicative significances for the wetland hydro-environment. For example, the occurrence of Myriophyllum spicatum + Potamongeton crispus community was an indicator for severe eutrophication, while that of Batrachium pekinens community could he regarded as an indicator of better water quality.

不同沉水植物群落分类组对环境因子有明显的指示意义，狐尾藻＋菹草群落是水体严重富营养化的表现，而北京水毛茛群落的出现是水质较好的表现。

And all the submerged macrophytes absorbed total phosphorous in water effectively and the removal rate of Ceratophyllum demersum with 9175％,9244％ in the Spring and Summer experiment respectively,was the best.

采用人工模拟方法，选取武汉市东湖的春季优势种金鱼藻、伊乐藻和菹草，夏季优势种类金鱼藻、狐尾藻和苦草，在春夏两个季节分别对东湖重度富营养化水体磷的去除效果进行了比较研究。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.
