SITUATION AND PREVENTION AND CONTROL SYSTEM CONSTRUCTION OF INVASIVE ALIEN SPECIES——GLOBAL PERSPECTIVE AND CHINA EXAMPLE
Invasive alien species poses a serious threat to China and the world's ecological security,biodiversity,and agricultural production. Strengthening the prevention and control of invasive alien species can help ensure national food security and biodiversity protection. Through literature analysis,based on the current situation of invasive alien species worldwide and in China,as well as the effectiveness of existing prevention and control work in China,this paper explored the problems in the prevention and control of invasive alien species in China and proposed corresponding countermeasures and suggestions. Research found that China was heavily affected by invasive alien species,and common invasive species include Canadian goldenrod,crocodile eel,grassland armyworm,etc. In recent years,China had achieved significant results in the prevention and control of alien invasive species,and had initially established a comprehensive regulatory and prevention system. However,there were still many shortcomings in many aspects,such as unsound institutional provisions in the legal systems,unreasonable operational mechanisms in administrative system,insufficient monitoring and identification capabilities in prevention and control technology,insufficiency of the breadth and depth in public participation,imperfection mechanisms and agreements in international cooperation. Based on international practices and experience,it is recommended to accelerate the enhancement of the framework for the management and control of invasive alien species,reshape the operational structure of "evaluation-management",strengthen technological support,encourage public participation,strengthen international exchanges and cooperation,in order to further enhance the level of prevention and control of the invasion of alien species in China.
