摘要
凤眼莲(Eichhorniacrassipes)原产南美洲,被列为世界十大恶性杂草之一,现已入侵了非洲、亚洲、北美洲、大洋州、甚至欧洲等 5个大洲,至少 6 2个国家和地区都受到了凤眼莲入侵的危害。凤眼莲的入侵已经引起了一系列的生态、经济、社会问题:首先,它改变了当地水体生态系统的物理、化学环境,进而影响水体生态系统的生物多样性,破坏食物链、物质循环等生态过程的正常运行;其次,凤眼莲造成当地经济的重大损失,航运、渔业、水利等都受到了危害;再次,凤眼莲的入侵爆发也对当地居民饮水、健康等造成威胁。目前,对于凤眼莲的控制及其治理主要有物理的、化学的、以及生物的等 3种方法。利用天敌、病菌、以及化感作用等的生物控制被许多专家和学者推崇,同时,利用生物控制凤眼莲入侵也日益成为研究的热点。但是,综合目前对于凤眼莲的认识和研究,仍然具有片面性,需要从生物特性、种群生态、生态系统等方面深入研究凤眼莲入侵机制。而利用生物控制凤眼莲的研究和技术尚不完善,需要进行种间竞争、捕食及遗传变异等方面的探讨和研究。通过总结控制凤眼莲各种方法的长处和不足,最后指出利用生物的方法,并结合污水治理、水系宏观调控及监测等方法,综合治理凤眼莲,是十分必要的,而且也是最具有前景的。
