浅谈环渤海地区互花米草(Spartina alterniflora)防治建议

互花米草（Spartina alterniflora）已成为我国沿海危害严重的恶性入侵植物，严重威胁海洋生态安全，特别是互花米草入侵对环渤海地区的生态安全构成极大威胁。本文综述了环渤海地区互花米草引种历史和入侵情况，简析了互花米草治理现状和存在问题，提出环渤海各沿海省市应形成联防联治机制，建立完善的“监测+预警”管理体系，制定互花米草分区防治措施，形成“最优治理决策支持系统+综合去除技术+去除后长效维持技术”三位一体的互花米草“长效治理”技术与管理体系，同时加快互花米草利用的研发进程。

Discussion on prevention and control of invasive Spartina alterniflora in Bohai rim region

Spartina alterniflora was a catastrophic invasive plant species along the coast of China, and it has seriously threatened marine ecological security, especially in Bohai rim region. Our present research reviews the history of Spartina alterniflora introduction, the status of invasion and the treatment in these area. Moreover, our research implied that the following measures should be considered in joint prevention and control mechanism to control Spartina alterniflora for all coastal provinces and municipalities. First, a consummate monitoring and precaution supervision system should be established in preventing the Spartina alterniflora invasion at our target area. Second, long-term governance system which included zoning prevention and control measures, comprehensive removal and long-term maintenance techniques, and optimal governance decision supports should be integrated in the comprehensive consideration during the project implementation. Additionally, the future research should give priority to the Spartina alterniflora development and utilization.
