Chengdu "foreign households" you don't know!It may be all foreign invasive species

Recently, the dried lake water in Ruzhou, Henan has attracted widespread attention from the public, and the two "strange fish" that everyone wants to catch is actually a great threat to the regional water ecology. Foreign species.

On August 29, two "strange fish" were also found in the viewing pool of Dafengjing Community, Xintu District, Chengdu. The shape was similar to the crocodile cricket. The strange fish "appeared, waiting for the subsequent confirmation.

In the face of these "foreign households", we can't help asking, what is foreign invasion species? How did they invade? Is there any foreign invasion species before Chengdu?

What is a foreign invasion species?

The so -called foreign invasion species refers to foreign species that transmitted colonies and bring threats or harm to ecosystems, habitats, and species, affecting my country's ecological environment, and harming the sustainable development of agriculture, forestry, animal husbandry and fishery.

According to the "2020 China Ecological Environmental Statistics": my country has found more than 660 species of foreign invasion species. Among them, 71 types have caused or have potential threats to the natural ecosystem and have been included in the "List of Chinese Foreign Invasion". In the first quarter of 2022, the nation's customs intercepted 173 kinds of harmful creatures and 139,000 times.

Does Chengdu also have foreign invasion species?

In fact, Chengdu has found foreign invasion species in recent years.

Purple stems Zelan

In June 2022, a foreign invasive plant -Zixia Zelan was found near the green space near Erxian Bridge in Chenghua District.

At that time, more than 20 purple stems Zelan was found at the scene. The relevant departments immediately acted immediately. In accordance with the expert's proposal plan, all the purple stem Zelan found out of the purple stem Zelan was eliminated and destroyed.

Zixian Zelan is native to the Americas. It can be called the "number one killer" in the plant world. It is extremely dangerous. It not only has a strong breeding and communication ability, but also inhibits the growth of other plants.

"Hard God Beetle"

In April 2022, the Chengdu Post Office Customs seized 4 live body beetles during the inspection of a batch of entry mail, which was identified as a halberd golden turtle.

As one of the longest beetles in the world, the long halberd and golden turtle has great strength and is often called "strong god beetle".

In fact, insects belong to the prohibition of postal objects stipulated in the "Animal and Plants and its products and other quarantine substances that are prohibited and sent to the countryside of the People's Republic of China. There are large hidden dangers of biological safety.

"One yellow flower in Canada"

In November 2021, Chengdu found two "Canadian Yellow Flowers" invasion.

A yellow flower in Canada was native to North America and was called "ecological killer". During the growth process, the underground roots will continue to spread around. After spreading, it will snatch water, nutrition and growth space with other plants, causing local plants to continue to apoptosis, which not only endangers agricultural production, but also seriously affects the local ecological environment.

In March 2020, the Customs of the Post Office of Chengdu Customs intercepted two plants similar to taro -like fresh plants from Thailand's entry mailing objects. The seeds are Tridax Procumbens, and the nematodes are skids and small rods.

Yu Mangju is native to tropical America. It is a severe invasion of plants at the 2nd level 2 and has been included in the "Chinese Invasion Plants List".

In fact, it is not uncommon for foreign invasive plants to be in Chengdu. Related information shows that there are 158 kinds of foreign invasive plants in Chengdu, of which 71 are obviously harmful.

For foreign invasion of animals, the bullfrogs and Fushou snails in the "Chinese Foreign Invasion of Species" have also been discovered. Among them, the most "conspicuous" foreign species are Fushou snails.

How to prevent and control foreign invasion species?

The prevention and control of foreign invasion species must improve the management system and improve the level of prevention and control. In response to foreign invasion species, my country has also introduced relevant regulations and measures.

In the "Biological Safety Law of the People's Republic of China", it stipulates that any unit or individual shall not be introduced, released or discarded by other species without authorization.

In June of this year, the Ministry of Agriculture and Rural Ministry, the Ministry of Natural Resources, the Ministry of Ecology and Environment, and the General Administration of Customs jointly released the "Administrative Measures for Migraphic Invasion Species" and implemented it on August 1, 2022. The "Measures" stipulates that the customs improves overseas risk early warning and emergency treatment mechanisms, and strengthens the supervision of port quarantine supervision of ports such as ports such as incoming goods, transportation tools, delivery, and passenger luggage, cross -border e -commerce, and border people.

This year, relevant departments in Chengdu have also introduced relevant policies.

In order to effectively prevent and actively respond to the harm of foreign invasion species from the forestry industry in Longquan Mountain Park in Chengdu, in July, the Management Committee of the Longquan Mountain City Forest Park in Chengdu formulated the "Chengdu Longquan Mountain City Forest Park Forestry Forestry Forestry Foreign Invasion and Control Measures ( "Trial), soliciting public opinions through public announcements.

In response to the protection of wetland, Chengdu recently issued the "Chengdu Wetland Protection Regulations (Draft) (Draft)", and publicly solicited opinions. Among them, the "Regulations" clearly states that the introduction and release of foreign species to wetlands should be scientifically evaluated and approved in accordance with the law. In response to the problems of foreign invasion, on the one hand, the management system needs to be continuously improved, and on the other hand, it is inseparable from the efforts of society and individuals. For example, individuals should not blindly raise wild animals and plants due to factors such as hunting and strange attitude, and "Haitao" foreign creatures that are not available in natives will increase the risk of foreign species invasion.

The prevention and control of foreign species invasion is related to national food security, biological security and ecological safety, and preventing and controlling foreign invasion species is a long -term task. In the future, by building a series of "action" such as the construction of a full -chain prevention and control system, establishing an inter -coordination mechanism for the prevention and control of foreign invasion species, and strengthening the popularization of publicity and education and science, it is believed that it will better protect the national biological safety and ecological safety.
