According to reports, recently, "Chengdu City Center City Landscape Lighting Special Plan (2017-2025)" was released, and proposed a new practice - demarcation of "dark night protection zone." This coincides with the concept of “night protection” advocated by many non-profit organizations in the world in recent years. However, organizations such as the International Dark Night Association are looking for pure night sky stars in pure nature without natural industrial traces; and as a modern big city, Chengdu is an area that needs to be “dimmed” according to local conditions. Let the quiet return to the quiet, the noise return of the noise.
For the "dark night" in nature without traces of industrial lighting, it is easy to understand that the sky after sunset is either full of stars or no fingers. However, when it comes to the “night protection zone” in the city, many people may look blank: Why do modern cities need to protect “dark nights”? How do the colorful cities protect “dark nights”? “Dark night protection” and developments in many places nowadays Is the city "nighttime economy" contradictory?
Modern cities need to protect "dark nights" based on light pollution. Nowadays, in almost every city, whenever night falls, people are no longer seeing the stars, but the skyscrapers are shining, the neon advertisements on the street shops are shining, the city lights, the lights, the LED screens, etc. Facilities are everywhere, making the entire city bright and white. Light pollution not only erodes the beauty of the night sky, but also brings ecological problems, affects the natural growth of animals and plants, and invisible harm to human health, sleep, mood and other health elements. Therefore, effective control of light pollution has also made the public a "night" and has become the wish of many citizens. Chengdu's demarcation of the "Dark Night Protection Area" is naturally a response to this kind of folk voice, and it is a reflection of the harmony between the city and the ecological nature.
Then, in a big city like Chengdu, the fields of industry, commerce, technology, logistics, etc. are quite developed. How to protect the "night"? Let some areas of it return to the era of "night starry sky" with no trace of industrial illumination at night. Of course not possible. According to the "Planning", Chengdu will demarcate the "Dark Night Protection Area" in accordance with the principle of "the light is bright, the dark is dark, the reasonable division, the light and dark balance, and the source of urban light pollution is reduced", and the protected area and surrounding areas are strictly controlled. The use of the area's lighting, retaining the necessary functional lighting and static color and elegant landscape lighting, should not use high-brightness, high-power lighting facilities, and must not use dazzling glare, dynamic lighting devices. In other words, Chengdu “Dark Night Protection Area” is to minimize the impact of lighting on the urban environment under the premise of ensuring basic lighting.
The practice of demarcating the “dark night zone” in Chengdu is worth learning. Looking at the whole country, Hangzhou has also restricted the artificial light for the needs of ecological environmental protection. For this purpose, the “urban black sky protection zone” has been delineated. No landscape lighting facilities should be set up in this protected area, and functional lighting facilities should not be installed. There is a beam of light. The practice of Chengdu and Hangzhou is a human-oriented embodiment. It is the pursuit of harmony between man and nature. Let us see the local government's efforts to control light pollution.
Some people may think that "night protection" contradicts the creation of "no night city" and the development of "night economy." In fact, the urban areas related to “Never Night City” and “Night Economy” are areas where shopping, catering, tourism, entertainment, leisure and other consumer industries gather. The “Dark Night Protection Area” to be demarcated includes Longquan Mountain Forest Park, Huancheng Ecological Area and other natural ecological areas, residential concentration areas, industrial areas, etc. These areas are not business leisure gathering areas, which are dark at night. The place can indeed be dark, so that people may see fireflies, faint tree shadows, and long-lost starlights. It does not conflict with the development of the "night economy", but complements each other.
