"Go, go to the park!" "Ok, let's go." Since the implementation of "one change every three years", such voices can be seen almost everywhere. Why is this? Mainly because of a big change in the past three years-tearing down the wall and turning green. The project of tearing down the wall and penetrating the green is really a very important project, so that everyone can enjoy the green of the streets and lanes as long as there is a park, and double the popularity of the park. Take the Century Park in Yuhua District as an example. Once or twice when I was young. At that time I not only had high walls, but also needed tickets. Every time I go to the park gate, I will be blocked by a big wooden sign "Opening hours: 7: 00-2 1: 00 fare 2 yuan". There are scattered buildings around, except for the high TV tower, there is almost no view of the park from the outside. But it's different now. All the surrounding buildings, walls, etc. It has been demolished and a new flower bed has been added. Now you can almost see the scenery in the garden from the outside ... According to relevant experts, from an architectural point of view, the wall looks stiff, while the green inside is soft, giving people a more comfortable feeling. After the wall is removed, the landscape outside the courtyard will be integrated, and people's horizons will be broadened when walking on the street. Therefore, the green space will be broadened. Removing the fence is also beneficial to alleviate the greenhouse effect of the city. As an integral part of concrete and bricks, the fence can absorb a lot of heat, which naturally reduces the greenhouse effect of the city after being demolished. From the botanical point of view, tearing down the fence is more conducive to the normal growth of plants. After the fence is removed, the permeability will increase, and the plants inside and outside the courtyard can absorb more sunlight. In fact, many modern cities have no fences. It is understood that in America, many travelers are surprised that there is no wall in America. Residential quarters, shopping malls, schools, factories and institutions all have no walls. Even the White House has only a short transparent fence. In many modern cities, we can see: wide and straight roads, lawns in front of buildings, colorful flower beds, various forms of buildings ... Dalian, Zhuhai and other cities with better construction, without exception, all take tearing down walls to build cities without walls as the highlight. So I said: tearing down the wall and greening is really an important project of "three years of great change", a project to beautify the city and a project to benefit the people!
