Why are green belts that can be seen everywhere in China, but rare in Europe and the United States? Is it not necessary?
> > Did you discover it? In China's urban construction, green belts can be seen everywhere, whether it is the pleasing oleander on both sides of the road, or the beautiful and bright bougainvillea on the guardrail, even the creeper under the viaduct, also has a unique flavor. Bushes, in summer, it seems that the most color in China is green, but in some European and American countries, it seems that such green belts are rarely seen. So the question is, do you know how much green area in China? What is the role of green belts everywhere? >
Since the Industrial Revolution, environmental pollution seems to have become a global problem. Whether it is the development of cities, the increase of population, or the over-exploitation of energy, global warming is undoubtedly a strong evidence of environmental deterioration. Green plants and improving the level of greening are both important directions for urban development in China. As of 2020, the green coverage area of China's urban built-up areas has reached 1.4945 million hectares, the green area is 1.3381 million hectares, and the park green area is 401,600 hectares. .
In addition, the green coverage rate in the built-up area is as high as 38.22%, while the green space rate is 34.17%, and the per capita park green space area is about 10.66 square meters. At the same time, according to different regional characteristics, a large number of high-quality park green space and Tree-lined avenues, it can be seen that China's green belts can be seen everywhere, but why does the country do this? Let's look down.
Can you believe it? The green belt, which is inconspicuous in China, has such an important role. First of all, it can beautify the city and can also play a certain protective role. Take the creeper under the viaduct as an example, it not only fits the supporting part of the viaduct perfectly, see It is very beautiful, and it also protects the viaduct from the wind and the sun, which not only beautifies the environment, but also effectively prevents the weathering of the viaduct. I really can't underestimate these creepers.
Secondly, green belts in cities and highways are of great help to relieve visual fatigue. We all know that long-distance drivers staring at the front for a long time can easily lead to visual fatigue and cause car accidents. Don’t look at these green vegetation. They are very low, which can relieve vision while also protecting and even saving lives. It can be seen that the importance of green belts is self-evident. Again, green plants can absorb harmful gases, whether it is industrial pollution or automobile exhaust. , such as the oleander on both sides of the road, also known as the "green vacuum cleaner", which is both economical and a visual feast.
It can also absorb harmful gases in the air, so as to achieve the purpose of purifying the air. It plays a very important role in the protection of the environment. What you may not expect is that the existence of green belts can also offset the noise of vehicles and effectively improve the living conditions of urban residents. Experience, when it comes to this, some people may ask, since the green belt is so important, why is it rare in Europe and the United States? Is it because they don't pay attention to environmental protection? Or are there any unknown secrets? Let's look down.
do you know? Green belts, which are highly valued in China, are not often seen in European and American countries. What are the unknown reasons behind them? In fact, when it comes to environmental protection, many countries in Europe are not worse than us, but there may be the following reasons for the absence of green belts. First of all, it is the reason left over from history. You must know that the development of European countries is earlier than ours. In particular, the advent of the industrial revolution has also made the industries of European countries develop rapidly, and they are more inclined to aesthetics in architecture, so there are many unreasonable issues in urban planning.
For example, the issue of greening area was not considered, and people had no concept of environmental protection at that time. In the process of urban construction, there was no space for greening. Secondly, the land area was limited, and the area of Europe was only 10.16 million square kilometers. There are a total of 43 countries, and the land that can be allocated is not much, and the limited land can only be maximized. If the area of the green belt is increased, the houses in these countries will be denser, which is also a problem for the smoothness and safety of the roads. , buried a lot of hidden dangers.
Thirdly, due to climate reasons, most of Europe has a temperate maritime climate, with rainy summers and cold winters. This climate is not suitable for the growth of evergreen trees, but herbs are more suitable. Therefore, European and American countries are not without green belts. It's not that they don't pay attention to the protection of the environment, but they choose to replace them with more lawns. Although they are on a par with Chinese trees and bushes, they are obviously more suitable for Europeans. What do you think of this?
