| 摘 要： | 大规模外来种的引入是生物多样性下降主要原因之一，外来种的入侵已经引起了一系列的生态、经济、社会问题。从云南省凤眼莲入侵的现状，分析了入侵植物风眼莲引种的得失。对于风眼莲的控制及其治理主要有物理、化学以及生物方法，认为目前对风眼莲等入侵生物应采取综合治理的方法。同时引进植物外来种时，要对引进种的行为特性进行调查研究，注意其安全性。

| Abstract: | The invasion of non - indigenous species is the main reason of declining biodiversity, which has led to a series of ecological and economic and social problems. The positive and negative effects of water hyacinth invasion in Yunnan province are analyzed. There are physical and chemical and biological methods to control and treat the water hyacinth. This tells us that necessary research on the characteristics of the specie in advance when it may be brought to a new place. |
