Chapter 626

The failure of the ecological environment experiment really frustrated many researchers and Chen Xin, but it was just a dozen times of experiment failure, which did not make people lose their fighting spirit.

In addition, they always lead to the collapse of the whole ecosystem when they only join animals. If they are only plants, they can make the whole ecosystem maintain a relatively stable state for at least 500 years.

This also proves that the construction of artificial ecosystem is feasible, but compared with the situation that plants are relatively stable and controllable, animals are relatively more prone to change, which leads to the imbalance of ecosystem and eventually leads to ecological collapse.

Chen Xin's initial idea was to add animals to this relatively stable plant only ecosystem, but previous experiments have proved that this is not feasible.

The failure of the first few experiments is largely due to the mismatch between plants and animals, which makes them unable to coexist.

In the following experiments, they tried to put animals and plants together in the experiment, but the differences in reproduction speed between different species can easily lead to the collapse of the whole ecosystem.

This is why, after the failure of the 17th experiment, some people proposed to change their thinking.

Because according to the original idea, they have tried all the schemes they can try, and it has been proved that they must jump out of their original idea.

So after the 17th experiment, Chen Xin gave everyone a day off to have a rest and change their minds to see if they could produce some new ideas.

And he also tried to adjust his thinking, thinking about the problem.

An ecosystem is generally composed of four parts: abiotic environment, producer, consumer and decomposer. In order to maintain the operation of an ecosystem, these four parts are indispensable.

In Chen Xin's current experiments, the abiotic environment is the best guarantee, and it is also the most stable part of the four parts.

As for producers, they usually refer to the green plant part. Although this part is not as stable as the abiotic environment, it does not need to worry too much. They can already build a stable plant ecosystem.

However, the consumer part of the whole system really baffles Chen Xin and the researchers.

By definition, animals are consumers in the ecosystem, but in fact, every link in the whole food chain can be regarded as producers and consumers.

They consume the next level, and they will be consumed by the upper level of the food chain. Finally, the existence at the top of the food chain will be decomposed by the decomposer after death, forming a closed loop of the whole material cycle and energy flow.

Therefore, the supply and demand relationship between each species and other species is the key to maintain the balance of the whole ecosystem.

This is just like a production line, where raw materials are imported from the source, and the processing workshop processes the raw materials into parts, and then assembles them in the assembly workshop. The amount of work to be done in each link is calculated in advance.

If one of the links is more or less, it will lead to problems in the whole production line.

More will lead to more things piled up in a certain link, and less will lead to less final products of the production line.

It's just that the production line in the factory can be adjusted directly, but the ecological environment is obviously not so easy to control and adjust.

Although human beings can indeed play a regulatory role in the ecological environment of the Dome City, so that the entire ecological environment can persist for a longer time, if the ecosystem itself has problems, even if there is external interference, it will only operate for a period of time and eventually collapse.

And there are problems in some aspects, even external intervention is difficult to save the whole ecosystem.

This point can be clearly seen in the previous 16th and 17th experiments. The massive reproduction of insects creates a terrible scene like locust plague. Even if human intervention is involved, the final result is that the entire ecosystem must be rebuilt.

Of course, the result is that the whole ecosystem has been out of balance without external intervention.

If there is a monitoring system that can monitor the whole ecological environment all the time and deal with the problems and variables in time when they are found, it can indeed maintain the operation of the whole ecological system to a certain extent.

As long as the problems that lead to the collapse of the whole ecosystem don't happen in a moment, it can make the whole ecosystem run smoothly for a long time.

But Dome City can do this, but later if you want to restore the ecology of the whole blue star, it will not.

After all, human beings do not have such a strong power to monitor the ecology of the whole blue star, and timely adjust the possible problems.

Therefore, Chen Xin must find a way to make the whole ecosystem run smoothly without external interference.

But it's not easy?

Giving up thinking about this problem, Chen Xin decided to let his brain rest for a while and change his brain to see if he could have new inspiration.

So he left the research center and went back to his home.

Back home, Chen Xin noticed that Qin Lan was sitting on the sofa sorting out something, so he went over curiously and asked her, "what are you looking at?"

"Some photos. Among the things that Qing Yan brought back before, there are many photos of the past, so put them in order." Qin LAN answers Chen Xin's question and looks up at him: "why did you come back so early today?"

"I met some obstacles in my work, and the experiment failed again, so I just gave everyone a day off to let everyone have a rest and change their minds." Chen Xin said so, sat down beside Qin LAN, picked up her album and turned it up.

Most of the photos above are of them playing in Mo Qingyan's bar before, and some of them were taken when we went outdoors together.

Looking at these photos, Chen Xinfan recalled the happy times in the past and felt relaxed for a while.

However, when Chen Xin was looking through these photos, he suddenly noticed that one of them was different.

Qin Lan was photographed in the photo, but she was totally different from Chen Xin, who always made training clothes. Instead, she wore a long plain white dress and sat quietly in front of a table. In front of her, there was a glass ball like a fish tank with stones and small fish and algae.

Chen Xin's eyes are really attracted by the glass ball. He asked Qin LAN curiously, "a LAN, when did you take this picture? And what is this ball? If you don't open your mouth, won't the fish suffocate? "
