In terms of economic aggregate, Dongguang Province has long been the largest economic power province in China, and Handong Province behind it has been chasing hard for several years and has not been able to surpass it. 【Fengyun Reading Network.】

Enterprises located in Dongguang Province, such as Tengxun, Hua Wei, Meidi, Gree...... They are all well-known industrial giants.

In addition to the economic advantages of Dongguang Province, its adjacent Hong Kong is a world-class financial center, competing with super cities such as New York and Tokyo, radiating the whole of Southeast Asia, and Dongguang can be described as a perfect combination.

Because it is located in the southern part of the Chinese land, it belongs to the subtropical monsoon climate, and the precipitation in Dongguang Province is very abundant, humid and hot, and rich in species.

In addition, its transportation is developed and it communicates with the whole world, and the possibility of invasive species landing and breeding is much higher than that of most other regions, and it once became a paradise for invasive species in China.

Basically, the invasive species that Lin Han has seen before can be seen in Dongguang Province, and many invasive species that have not been seen before can also be seen in Dongguang Province.

In order to control invasive species, the Dongguang provincial government has to invest a lot of manpower and material resources every year, which consumes a lot of money but cannot be eradicated, which is troublesome.

The governance effect of Vientiane in Handong, Jiangsu and Zhejiang is already obvious to all, and with the letter of thanks from the Department of Health, the Dongguang Provincial Department of Agriculture did not hesitate to cooperate soon.

After Lin Han came to Dongguang, his movements were also very fast, taking a plane to travel between several cities, and the anti-green buff and eunuch buff covered the whole province, and all the invasive plants and some invasive animals were all extinct.

The remaining long-lived invasive animals, including "old friends" such as bullfrogs and Brazilian turtles, Lin Han dealt with them one by one according to the previous ideas.

Invasive animals with high edible value are often introduced into China as meat, so corresponding farms can often be found.

Lin Han came up with the same routine as dealing with bullfrogs, and such invasive animals soon entered the process of extinction.

If you can't eat it, if it's easy to collect, collect it and prepare it for disposal as organic waste.

If it is not easy to collect, it will be extinguished if it can be extinguished, and if it is not easy to be destroyed, it will be put away for the time being.

With the experience of dealing with Jiangsu and Zhejiang provinces, Lin Han's governance task in Dongguang Province this time can be said to be very efficient.

……

"Gaia, an invasive species in China, has been solved much now. Lin Han asked in his consciousness.

"Invasive plants have been eradicated by 33 percent, and invasive animals are only 25 percent, which is still a bit short," Gaia said. ”

More than 30% of the invasive plants have been eradicated, and one of the promotion conditions is considered complete. There is still 5% of the invasive animals left, and it is estimated that after the South China Sea and Hujian provinces are resolved, it will be more than enough.

The goal of invasive species control has been achieved, and the remaining amount of garbage needs to reach 50,000 tons.

There is still plenty of time, and there should be no problem in promoting to the intermediate earth envoy this year.

When the work of controlling invasive species in Dongguang Province was almost completed, the "Report on the Prevention and Control of Dengue Fever Epidemic" held by the Department of Health at CUHK, the highest university in Dongguang, was also held as scheduled.

Lin Han received the invitation, so on behalf of Vientiane, he went to CUHK to participate in the report meeting.

……

As a university named after the revolutionary pioneer Sun Yat-sen, CUHK can be said to be one of the best universities in Dongguang and even in China.

His biological achievements are even more prominent in the country, and it is no wonder that he was commissioned by the Department of Health and the venue for this seminar.

After coming to CUHK, Lin Han first walked around the school before heading to the conference hall where the seminar was held.

To Lin Han's surprise, Professor Chen Zheyu of Peking University also attended the report meeting in person.

Although Vientiane has had a lot of contact with the Institute of Microbiology of Peking University, not only Song Shuqing and Jiang Ruiyang are students of Professor Chen, but Lin Han has also communicated with him several times.

It's just that the contact between the two is basically carried out in Diàn Huà, and they haven't seen it in person before.

"It's better to hear than to see, Professor Chen is really extraordinary, and he deserves to be the youngest Changjiang scholar in China. Lin Han shook hands with Chen Zheyu and couldn't help but smile and said.

Professor Chan is less than 40 years old this year, and his dress is very simple and elegant, and he looks even younger.

To be honored as a Changjiang Scholar at this age is certainly not something that can be achieved by hard work alone.

In terms of temperament, Chen Zheyu can be said to be very close to the image of a scientist in people's hearts, and he has a sense of wisdom with poetry and books

Therefore, as long as many people see him for the first time, they will have an inexplicable sense of intelligence looking up in their hearts.

Chen Zheyu laughed: "In front of Mr. Lin, I don't dare to pretend to be young. ”

The two chatted casually, then entered the venue and sat down in two seats next to each other in the first row.

Attendees of the briefing were attended one after another, including CUHK University officials, the Director of the Provincial Department of Health, the Dengue Prevention and Control Committee, and of course some other scientific research institutions.

In addition, at the back of the venue were many students from the Faculty of Biology at CUHK.

These students include both běn kē students and graduate students, and many of them still have books or notebooks in their hands. There are even people who wear headphones and recite the word yīng yǔ as if nothing happened.

There was still a while before the report began, and everyone in the audience was talking in twos and threes.

"Mr. Lin, I heard that Vientiane's invasive species cleanup work in Dongguang is almost complete?" Professor Chen asked.

Lin Han nodded: "All the invasive plants, as well as most of the invasive animals, have been cleaned up. ”

Professor Chen couldn't help but ask, "Have you also removed the pine wood nematode?"

"Professor Chan also has research on invasive species?"

Professor Chen nodded slightly, as if recalling: "The invasion of pine wood nematodes in China was discovered by my master's supervisor more than 30 years ago. ”

As an invasive species, the case of pine wood nematode can be said to be chilling, and the lesson is extremely profound.

When it was first discovered in China, there were already mass deaths of pine trees in the pine forests around it.

At the time of discovery, it was only a few pine trees in the vicinity of the area that were in trouble.

However, the spread rate of pine wood nematode is alarming, and there has been no effective control.

In addition to the death of hundreds of millions of pine trees in China, it has also caused great harm to pine trees in many famous scenic spots.

The "welcome pine" of the Huangshan Scenic Area is famous, but the pine wood nematode is also approaching the scenic area, if the pine wood nematode invades the scenic area, then the "welcome pine" will be wiped out.

Therefore, the Huangshan Scenic Area did not hesitate to invest a huge amount of money to cut down all the coniferous forests within a few kilometers around the scenic area to form a quarantine zone of several kilometers, so that the welcome pine escaped a catastrophe. js3v3
