Zhang Wei knew before negotiating with the British that Australia was barren and desert was numerous, otherwise the British would not happily exchange western Australia to the Lanfang Kingdom. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 ｉｎｆｏ

In April, Zhang Wei asked the Royal Academy of Sciences to send an environmental research team to Australia to conduct environmental research to provide scientific guidance for the future construction of Australia.

The Academy of Sciences has dispatched researchers from several research institutes of the Faculty of Life Science and Medicine and the Faculty of Geosciences to form a large scientific expedition team to prepare a comprehensive scientific investigation of the four states of Australia, mainly investigating Australia's geology, soil, climate, vegetation, animals, ecological environment, recycling system and other aspects.

The expedition team was divided into four teams, which went to four states for inspection, and then summarized the information to produce a general expedition report.

The four expeditions followed the militia division and arrived at their intended locations on 20 April. The militia divisions of the four states assigned one platoon of cavalry to each expedition team to protect security and provide logistical supplies.

Due to Zhang Wei's urgency, the Academy of Sciences first issued a scientific expedition brief at the end of May and provided it to Zhang Wei for reference.

In the brief of the scientific expedition, it was first suggested that a large number of immigrants should not be sent to Australia, except for those who lived in cities and mines and railways, and the upper limit of the population engaged in planting and breeding was proposed, and the number of people engaged in planting and breeding should not exceed 100,000 in the central, northern and western states, and 1 million in the southern state, otherwise the ecology would be seriously damaged.

Then there is the content of the scientific expedition to Australia:

First of all, Australia's land is barren, fertilizer is insufficient, rainfall is low, and the land is desertified and salinized.

The land in Australia is relatively old, and after hundreds of millions of years of rain, the soil fertility has been seriously lost, and it is not suitable for the development of agriculture and animal husbandry unless it is in the river valley area. Less rain and more evaporation, resulting in salt remaining in the soil and gradually accumulating, and the land becomes salinized; Precipitation is low, except for some coastal areas, where there is perennial drought in the interior, leading to desertification of inland land.

The second is that the British have vigorously developed the local aquaculture industry, due to overgrazing, many pastures have been degraded, pastures are deserted, and they are on the verge of desertification, which must be remedied. The forests in Australia have grown up over hundreds or even thousands of years, and the British have plundered and destructed the local native forests for timber and to expand pastures, resulting in serious ecological degradation, and because of the poor local soil, it is difficult for the forests to be restored by themselves after being destroyed. These phenomena, in turn, have led to an acceleration of desertification.

Again, there is no way to decompose cow and sheep manure here, covering the pasture and affecting the growth of the pasture, either manually treated or introduced into the organism for decomposition.

Finally, there is the ecological destruction of alien species, there were no rabbits in Australia, it was British immigrants who brought rabbits to Australia, where rabbits have no natural enemies, coupled with sparse population, vast grasslands, resulting in a large number of rabbits, and cattle and sheep to earn pastures, resulting in accelerated degradation of pastures, rabbits have now spread to Nanzhou and Xizhou, and the number of rabbits must be curbed.

For this time, Zhang Wei specially convened a meeting of the Academy of Sciences and the Government Council to discuss the future development direction of Australia.

The opinion of the Government Council is that since Australia's ecology is so fragile, it is necessary to reduce immigration, let its ecology recover slowly, and only establish some farms or grape plantations in Southern State; focus on mining and smelting; Specialized organization of indigenous people to plant trees. In addition, now a large area of land on the island of Java is vacant, the immigrants are completely resettled on the island of Java, the sultan of the Yogyakarta region has been solved, the local strong natives have been captured as free labor, the remaining population has been relocated to the island of Papua, the vacant land arrangement of millions of farmers is still very relaxed, there is a large amount of volcanic ash left after the volcanic eruption, the land is fertile, there is no shortage of rain, it is a good place to develop agricultural planting, the cost of immigrating to Java Island is low, and there is no need to transport supplies from the capital like Australia, Just the transportation cost saves a lot, and the effect is quick in the immigrants, and the immigrants can meet the self-sufficiency of the year.

The view of the Academy of Sciences is that natural restoration alone is too difficult and must be remediated and disturbed. The states must now be ordered to ban the felling of local trees and the extraction of groundwater; The treatment of cow and sheep manure can be introduced from the mainland; For rabbits, it can only be a combination of artificial capture and virus killing, and it is not yet possible to introduce rabbits' natural enemies, otherwise it is likely to be another alien species disaster.

Zhang Wei is also meditating, with a hundred years of insight beyond reality, he will definitely come up with a good way, but unfortunately, he really didn't come up with a good way. In the end, we can only follow the ideas of the Academy of Sciences and the Government Affairs Yuan.

So Zhang Wei said: "It is not possible to immigrate, more or less some immigrants are required to fill the territory left after the withdrawal of the British, especially when the British withdraw, it is impossible to pull away the cattle and sheep, and the vineyards and farms cannot be moved, these are ready-made wealth, and it is a waste if it is not used well, but in the future, it is necessary to control the number of cattle and sheep, plant more trees, build more dams, and do not exploit groundwater; For cattle and sheep manure, let the state order that all estates and pastures must crush the cattle and sheep manure and return it to the field to maintain the fertility of the pasture, and the state government will inspect it from time to time. ”

Seeing that everyone didn't speak, Zhang Wei continued: "Now let's send most of the immigrants to Yogyakarta, and leave a small part in Australia, and when we completely occupy Australia, we can use the low-lying places in Australia to build lakes, and I can use the system warehouse function to move the river water on Java Island to Australia, and fill a few more artificial lakes; The system will also transport the volcanic ash left by several volcanic eruptions on the island of Java to Australia to improve the local soil structure, and it is believed that it will not be long before Australia will be renewed. ”

After listening to Zhang Wei's method, the staff of the Academy of Sciences said: "Your Majesty's method is good, but the time and cycle are too long. ”

"There is no hurry, when the time comes, first build lakes and oases along the railway, and then slowly develop inland, as long as there is water and good soil, just send more indigenous people to work, and start to build oases, and when there are more oases, the local climate may change."

Zheng Daoyou said: "Your Majesty, this is not in a hurry, let the Academy of Sciences study as a subject first, and now we still set the current development ideas of Australia." ”

Zhang Wei thought about it for a while and said: "Okay, according to the brief investigation and what we just discussed, the number of immigrants to Australia to engage in agricultural planting and animal husbandry has been reduced by half, 50,000 immigrants from Xizhou, Beizhou and Zhongzhou, and 500,000 immigrants from Nanzhou; Orders issued by the Council to the states prohibiting the exploitation of groundwater and the felling of any trees; encourage reforestation in the states; control the number of cattle and sheep raised and grazing, and cattle and sheep manure must be returned to the field; The Academy of Sciences set up a research group to study viruses against rabbits; Australian farmers can be equipped with hunting rifles to hunt rabbits. That's all for the time being, and we will find countermeasures when the scientific expedition team makes any new discoveries. ”
