水葫芦用于水质污染治理的生态环境效应及其对策研究

水葫芦净化水质的应用虽然已取得一定的成效，但是，由此却也伴生出一系列的问题。任何外来物种均是“双刃剑”，其带来的生态环境效应有利有弊。正确客观评估水葫芦这样的外来种的生态环境效应，对水葫芦生态工程净化工艺进行科学设计并逐步完善其净化系统，加强和优化生态工程的管理，从而使水葫芦达到对污染水体的最佳净化效果和对环境的最低危害程度，造福人类。

Research on the Ecological Environment Effect of Water Hyacinth Using in the Water Pollution Government and Its Countermeasure

Though the use of water hyacinth in purifying water quality has obtained a certain result, it also brings a series of associated questions. Any extemal species are ＂double - edged swords＂. It brings advantages also shortcomings for the ecological environment, Appraise the ecological environment effect objectively and correct that external species such as water hyacinth brings. Design the scientific purification system of water hyacinth ecological project and make the purification system better step by step. Strength and the ecological engineering management, so as to achieve the best purification effect to the polluted water and the lowest harm degree to the environment, and benefit the humanity.
