Summary. More than 660 invasive alien species have been discovered in China, and their invasion pathways mainly include: natural invasion.

Biological hazards caused by natural migration of plant seeds or animal larvae through air movements, water movements, or insect and bird transmission; Artificial introduction is divided into intentional introduction and unintentional introduction. Among them, it is intended to be introduced for the purpose of viewing and so on. Inadvertently introduced is inadvertently introduced with the import and export of ** sea vessels or inbound passengers.

In addition, fruits, meat, and even shoe soles brought by inbound passengers will also become a route for the invasion of alien species.

Biological hazards caused by natural migration of plant seeds or animal larvae through air movements, water movements, or insect and bird transmission; Artificial introduction is divided into intentional introduction and unintentional introduction.

Among them, it is intended to be introduced for the purpose of viewing and so on. Inadvertently introduced is inadvertently introduced with the import and export of ** sea vessels or inbound passengers. In addition, fruits, meat, and even shoe soles brought by inbound passengers will also become a route for the invasion of alien species.

The main reason is that there is a gap in the legislative aspect for the time being. "One of the important reasons for the large-scale invasion and rapid spread of alien species is that China's legislation on the invasion of alien species is relatively lagging behind. "In order to solve and control the damage caused by invasive alien species to China's ecological environment and economy, it is urgent to establish a special law to control the invasion of alien species."

There are three pathways of alien species invasion: conscious introduction, unintentional introduction and natural invasion. For example, in the 70s of the 20th century, China introduced water hyacinth (water hyacinth) native to South America as pig feed, but water hyacinth has spread all over rivers, lakes and ponds in North China, East China, Central China and South China.

In the 1,000-hectare Dianchi Lake, water hyacinth has grown wildly, seriously damaging the structure and function of the aquatic ecosystem, and has led to the death of a large number of aquatic animals and plants. It is a natural invasion to be introduced by its own diffusion or with the help of natural forces, and microchamomile and American spotted diver fly are all invaded into China by natural factors. The unconscious introduction is the species that are introduced with activities such as **, transportation, tourism, etc., and the invasion of the American white moth belongs to this category.

Invasive species are found in all provinces, autonomous regions and municipalities in China, involving almost all ecosystems, from vertebrates and invertebrates to tall and low plants, as well as fungi, bacteria and viruses. Cao Aocheng, a researcher at the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences, pointed out.

Summary. Answer: Hello kiss How should China deal with the invasion of alien species, the customs also strictly prevent the import of various animal diseases, strengthen the pre-inspection of imported animals abroad, and strictly check the source quarantine to ensure the safety and health of imported breeding animals.

We continued to strengthen the prevention and control of major animal and plant epidemics such as African swine fever, highly pathogenic avian influenza and desert locusts, and issued 8 ban announcements and 6 warning notices, involving 12 countries (regions). Recently, Daxie Customs, a subsidiary of Ningbo Customs, found a rare cockroach (cockroach) in the monitoring of vector organisms at the port, and the front-line customs officers sent the cockroach samples to the National Key Laboratory of Medical Vector Biological Monitoring and Pathogen Detection of Ningbo Customs in a timely manner. After identification, the cockroach was Shen's cockroach, which was discovered for the first time in the national port.

In recent years, frequent invasions of alien species have become the focus of customs control. Especially with the development of Internet shopping and international logistics, some domestic insect and plant lovers blindly pursue "new, strange and special", and mail live animals and plants or specimens in violation of regulations by concealing reports and concealment.
