黄河三角洲地区大米草入侵与防治对策

Biological Invasion Countermeasure of Spartina spp. in the Yellow River Delta Coast

大米草在黄河三角洲地区促淤造陆、保滩护岸、环境保护等方面发挥重要作用.近年来随着大米草的蔓延,其积极作用也日渐被负面影响所取代,并且已经对山东省沿海滩涂和海洋渔业产生比较严重的后果.通过分析黄河三角洲地区大米草入侵现状和危害,提出黄河三角洲地区大米草入侵的总体治理方案,为黄河三角洲地区大米草入侵防治提供科学依据.

Spatina spp. have played a positive role on coastal protection in the yellow river delta coast. However, with the Spatina expansion, the negative role of Spatina has surpassed their positive role and has some bad effects on wetlands biodiversity and marine aquaculture. In the paper, the invasion condition and damage of Spatina biological invasion in the yellow river delta coast are analyzed. The countermeasures of Spartina control in the yellow river delta coast are suggested, and therefore it is expected to be helpful to Spartina control.
