Two Thousand One Hundred and Nineteen Water Conservancy Battle
Brothers, I have opened a new book again: Restarting my life: I can call myself ten years ago. Brothers help to collect and recommend a few!
********************
And as early as the early 1980s, the natural environment of this generation was actually quite good.
Although there are some deserts, they are not as large as they are now, and there are no dust storms.
And all the changes have to start in the 1990s, when the state allowed some local private hydropower.
The local natural environment is already fragile enough, but there is still a Liao River originating from the Taihang Mountains, flowing through the area.
To replenish water to many small rivers in the area...
You must know that the Liaohe River is one of the five most important inland rivers in northern my country, and the Liaohe River is also divided into the East Liaohe River and the West Liaohe River.
The Dongliao River goes through the inner ring area of the Taihang Mountains, going around the northern part of Hebei, Beijing and Tianjin, and finally enters the sea at Jinmen.
The West Liaohe River, on the other hand, is a prairie area that travels along the Mongolian Province, and finally enters the sea in Liao Province.
But since the country began to allow some places to build hydropower stations without permission, it can be said to have caused a serious damage to the ecological balance of the northern region.
Because the ecological balance of many northern regions is relatively fragile, it is not suitable to build too many hydropower stations.
If it is in the southern region where there is a lot of rain, it does not matter. Even sometimes, building a few more hydropower stations will have a good regulatory effect on local flood control.
But the northern region is already short of water, and many areas have little rainfall, and even after rainfall, the water storage capacity of the land is relatively poor.
It can be said that the local natural environment is completely irrigated and maintained by a few passing rivers.
The Horqin area was maintained by the West Liaohe River. At that time, there was a relatively important stream nearby called the Xilamulun River.
At that time, although there were some land desertification problems in the local area, it was not so serious.
But since private hydropower was allowed above, many local governments have begun to build indiscriminately from the source.
Since the Taihang Mountains, various small hydropower stations have been built, and the electricity generated is not much.
But it caused serious ecological damage to the lower reaches of the river.
As early as the 1980s, there were still heavy rains in the Horqin area every year, and flood control was required every year.
But after the 1990s, the Xiliao River stopped flowing, and even the Xilamulun River dried up.
The surrounding Molimiao Reservoir, Hongshan Reservoir and other reservoirs have also dried up.
The situation after that was a result of the destruction of the local grasslands by the Americans when they were developing their Midwest.
The land was deserted a lot, and then the dust storms started to blow up.
Because it is located in the most upstream area of the capital area, the Three North Shelter Forest at that time was almost useless.
At least 20% of the sandstorms that blew up in the capital in those days were at least 20% here.
At that time, many environmentalists were also puzzled.
what's the problem?
We have also built the Three-North Shelterbelt, and we also asked those places to return farmland to forests?
Why is this land desertification problem so serious?
So many experts were sent out to investigate, and in the end, they naturally found the source, that is, in the Taihang Mountains, as well as the small hydropower stations that were randomly built and intercepted in the waterway of the Xiliao River.
Even many of these small hydropower stations have not been approved, and they are completely built by some wealthy people in the local area.
Just for such a petty profit, in the end, the entire downstream natural environment was destroyed.
The above has also ordered rectification many times, but the problem is that this seemingly inconspicuous hydropower may have to pay a lot of taxes to these local governments every year.
Therefore, there is no motivation to rectify the place, so it has been stalemate.
The situation did not improve until around 2008, when the country got serious.
And after that, the establishment of large-scale thermal power projects has also made our power supply more abundant.
The power grid is also not interested in these small hydropower, not to mention they have no formalities.
Therefore, it is often not connected to the grid for you. Even if it is connected to the grid, it will drag you during settlement.
It is precisely because they see that the accounts are getting worse and worse, so many small hydropower plants are reluctant to engage in them.
In this way, many small hydropower stations have been gradually dismantled, but they have not been dismantled until now.
As for the Xiliao River, it has not yet resumed its circulation.
But one thing is certain, that is, the natural environment in the Horqin area has obviously gradually improved in recent years.
Years of insisting on afforestation, began to play a role gradually.
Coupled with the northward shift of the precipitation line in recent years, the rainfall here has gradually become abundant.
This time, the focus of the investigation is on this area, and the reason is very simple, because it is too close to the Gyeonggi area.
The natural environment here has improved, and the Gyeonggi region is the most direct beneficiary.
What's more, the Celebrity Chef Group still has several big projects here.
If nothing else, their optoelectronic project is a key demonstration project here.
The local area originally had several large-scale thermal power projects, of which a quarter of the electricity in the capital was supplied by the thermal power plant here.
With the addition of the celebrity chef group, more and more electricity is generated in this area.
And because the thermal power here directly supplies the capital, it is easy to reduce production.
Therefore, considering the above, the electricity of the famous chef group, on the one hand, is connected to the grid to supply Hebei and Jinmen, and part of it is also diverted to Liao Province.
But the problem is that there is still a lot of excess electricity, what should I do?
After all, the Celebrity Chef Group has said that many photovoltaic power plants will be built here. After all, they can contract nearly 100,000 square kilometers of desertified areas here.
The original intention of other enterprises is absolutely good, and we cannot dispel the enthusiasm of other enterprises!
But the electricity from such a large area must not be digested for a while, so it must be used like a method.
After examining the entire area, the expert group made a recommendation.
That is to make use of the abandoned Hongshan Reservoir and Molimiao Reservoir.
These two places were originally reservoirs with very large water storage, and they were surrounded by granite geology.
The geological structure is stable, which can support a large amount of water resources and ensure that it will not penetrate into the ground.
In the past two years, the Horqin area has experienced a lot of rainfall every year.
But most of this rainwater is wasted in vain because there is no suitable storage facility.
If these two reservoirs are used this time, at least one hundred West Lakes can be stored.
And the most troublesome problem in the past was that everyone knew that the precipitation should be collected into these two reservoirs.
The problem is that the reservoir is built in the mountains, and the terrain is generally relatively high.
If you want to store water in it, you naturally have to pump the water in.
In the past, it was because there were the Xiliao River and the Xilamulun River. When the water level was high, it was enough to dig ditches to drain the water.
But now because the two rivers are still dry, if you want to store water in the reservoir, you naturally need to pump water in.
Pumping water requires the use of a water pump, which requires electricity.
And these photovoltaic power plants of the famous chef group can provide them. As for the water pump, it doesn't cost a few dollars at all.
And the water is pumped in during the day and released at night to generate electricity.
This is a comprehensive utilization of hydropower project, which is an experimental project of great significance for the local area.
After the above inspection, an organized group of experts conducted a demonstration of the project.
The final conclusion is that the whole project is very operational.
In recent years, a large number of tree planting and sand protection operations in the Horqin area also require a large amount of water resources.
However, when the spring and autumn seasons come every year, it is the dry season of the local area, and the water shortage is the most.
If there are such two reservoirs to regulate the distribution of local water resources, it would be great.
As for the accumulation of a large amount of rainwater and snow in the reservoir, will this also evaporate?
Hey, this is also very simple, after all, people in the United States have worried about this problem for a long time.
In California, USA, there are also several large hydroelectric systems.
One of the most famous methods is to throw sunshade balls into the reservoir.
As early as a few years ago, the California government of the United States began to put sunshade balls into local reservoirs.
And after several years of operation, they put a total of 91 million sunshade balls in the reservoir of about 71 hectares in the territory.
The main function of these sunshade balls is to reduce the evaporation of water in the reservoir.
Many people may not know that, in fact, for the reservoir, the evaporation of a large amount of water vapor every year is the most troublesome problem for them.
And after these sunshade balls were put in, these reservoirs in California reduced water vapor evaporation by as much as 135 million tons per year...
This amount can be said to be quite staggering. If you are more specific, this fresh water is more than enough for Los Angeles people for a year.
This is still the case that the old beauty likes waste so much, if this is for us.
It's enough for the people in the two big cities of Beijing and Jinmen to spend a year together, which is more than enough.
And there are so many other unexpected benefits of throwing this shade ball in a reservoir.
For example, it can isolate the entry of dust and bird droppings, which can prevent the photosynthesis of algae and reduce the large-scale outbreak of algae.
In this way, the water quality can be improved and the content of carcinogenic substances in the water can be reduced.
In addition, it can effectively reduce the production of bromine and reduce the toxicity of water.
Anyway, no matter how you look at it, there are many advantages, and of course not without disadvantages.
The disadvantage is that it is more expensive...
The Americans spent a total of more than 30 million dollars in order to put sunshade balls into these reservoirs.
In other words, it is more than two billion words...
This price, if put on our side, is enough to build a new reservoir.
Of course, this is the cost of the Americans, after all, they have to order these sunshade balls from us and ship them to the United States.
The cost in the middle is quite a lot, if we make it locally and transport it for delivery.
The cost is naturally much lower...
