从加强生态环境保护角度探析我国外来入侵物种防控策略

Analysis of Prevention and Control Strategies for Invasive Alien Species in China

外来入侵物种对我国生态安全、生物安全和粮食安全形成了重大威胁。我国已经在法律法规、体制机制和控制清除等方面采取一系列措施,并取得一定效果,但外来入侵物种防控工作中的某些薄弱环节问题未能得到有效解决,仍存在防控成效不足等问题。在分析我国外来物种入侵形势以及涉及外来入侵物种的不同利益主体及其利益关系的基础上,探讨了我国外来入侵物种防控体系建设的进展和存在问题,提出树立正确防控指导思想、合理界定防控对象、建立健全防控法律体系、完善防控体制机制和开展综合治理等对策建议。

The issue caused by invasive alien species is a major threat to ecological security,biosafety and food security in China.A series of measures has been undertaken nationally,including laws and regulations,institutional mechanisms,control and clearance.However,several weaknesses in the prevention and control of invasive alien species have not yet been resolved,and the effectiveness of controls remains inadequate.Here,the invasive status of alien species,as well as different stakeholders and their relationship involved in invasive alien species prevention and control were analyzed.The progress and problems of the invasive alien species prevention and control systems in China were also investigated.In addition,approaches for establishing effective prevention and control have been proposed,including the development of an appropriate guiding ideology,definition of the objectives of prevention and control,establishment of a sound legal framework,improvement of systems and mechanisms for prevention and control,and implementation of comprehensive management.
