福建机械法治理凤眼莲的思考

Consideration of Mechanical Control over Water Hyacinth in FUJIAN

凤眼莲是最危险的外来入侵物种之一。近年福建省凤眼莲危害严重,在调研省内与国内凤眼莲机械治理的基础上,着重评价机械治理的应急作用与突出的节约、高效经济效果。为消除凤眼莲隐患,提出机械治理凤眼莲的总体思路和对策:应建立清理凤眼莲的日常保洁机制和常规应急机制,要切断凤眼莲的富营养源,及时清理凤眼莲的发生源,并做好凤眼莲综合利用的开发源,以抑制凤眼莲维持在一个生态平衡的低限量水平。

Water hyacinth is one of the most dangerous foreign species, harming public interest in Fujian Based on a complete investigation of different mechanical control measures and their successful applications in controlling the infestation of water hyacinth in China, this paper focuses on evaluating the emergency functions of mechanical control over water hyacinth and its good economic benefits. In order to get rid of hidden danger of water hyacinth, the paper raises a general idea and countermeasures to treat water hyacinth. The paper states that a daily clearing of water hyacinth mechanism and an emergency mechanism should be established to keep clean of water-head and to utilize comprehensively the water hyacinth in an attempt to control the water hyacinth at a lower ecological level.
