On June 21, the China biodiversity conservation and Green Development Foundation (hereinafter referred to as green hair) held press conference, green will star Working Committee (hereinafter referred to as Chinese stars) director Wang Xiaohua announced in support of the Government of Tibet Autonomous Region, China's first Chinese night sky protection pilot on June 7, 11th settled in Ali, nagqu in Tibet. Ali the night protected areas will be between future and nagqu night Park, Star resource protection and astronomical observations, and create sets of "scientific research, environmental protection, science popularization" as one of the stars of cultural industries.
According to reports, the night protection pilot project during the construction, planning, transformation and management will be carried out in accordance with international standards, such as prohibiting the use of high-power strong light sources, there should be no upward projection of the light in the reserves, uses the entire shelter lighting, correlated color temperature should not exceed 4000k, such as the prevention and control of light pollution. While supporting the stars experience, telescopes and guest service areas such as infrastructure, cultural industry development in promoting local stars.
Asked why one of the first sites in Tibet? Wang Xiaohua pointed out that Tibet has advantages in night protection resources. "This population, low lighting; raised sea, precipitation rarely; the sky is very rich in resources, with innate natural conditions for building night protection. ”
The case of Ali, sunny days rate reaches above 80%, transparency of the atmosphere below 0.1 atmospheric stability, seeing less than 0.8, excellent quality of the night sky.
In fact, after more than 10 years of site selection, new top Observatory in the world---Ali station of the National Observatory on the ground here.
As said by the Deputy Chairman of the Tibet Autonomous Region, sensitive, Ali and nagchu night sky project, will provide the strategic location of astronomy and nature area with environmental protection at night, opening up new stars for local cultural industries and will provide demonstration and for the cause of the night sky in the country-oriented, has a very important strategic and creative value.
Protection is not the night to make the city "dark"
In 1988, on the initiative of a number of experts, "combating light pollution at night and the environment" awareness and concern by the international community, is committed to international organizations---the international dark sky Protection Association (International Dark-Sky Association) came into being, called for strengthening of planning and management, reasonable arrangement of light sources to prevent light pollution, allowing people to find place where you can enjoy the starry sky. After nearly 30 years of development, the Association has in the United States, Africa, Europe, Oceania accredited 66 night protection; but in Asia, this type of authentication protection is blank.
With the development of the times, creating dark sanctuary in China is also on the agenda. This time in Ngari, Tibet, nagqu established protection is seen as China's international night protection to breakthrough and could become the first in Asia to receive international certification night protection.
Night night protection is to make the city no longer development, reduced lighting it?
Facing these questions, legal department director Wang Wen-Yong said of the green hair, "the dark sky protection, not that called on the city to abandon the use of light". He pointed out that the development of artificial light is the crystallization of human wisdom, protection and this does not contradict the night. "We advocate is moderation of desires, get rid of excessive use. Such as reducing the use of those who deliberately took over the lights. ”
Wang Xiaohua pointed out that night protection objectives are not cities, but in national parks, nature reserves and other natural conditions are better places, through the promotion of scientific and reasonable lighting, lighting control, so that the "light pollution" are no longer spreading, "for people to get out of the city where he can be found enjoying the stars. ”
Night protection to advance is
Landing was delighted for the project at the same time, experts from the Chinese stars will also feel fortunate. "Today, Ali star protection is also imminent. If you continue to walk past the old, Ali and other regions will also be ' successful ' second. "Wang Xiaohua said.
This "booming" refers to the 50 's of last century, China's National Observatory's Xinglong Observatory, Xinglong County, Chengde city, Hebei province, had always been key national optical observatory. But 60 years on, with the development of cities, rapid growth of local light pollution, reduced observations, has a serious impact on scientific research, Xinglong Observatory's significance has been greatly weakened.
At the seat of Government of Ngari Shiquanhe Town, "population gathering, entertainment, downtown. "Experts in the location of the green hair was greatly surprised. "A few years ago, there are bleak and isolated towns. Under this trend, without prior planning, management of the lighting, will repeat the mistakes is booming here. "Wang Wen-Yong said.
It is learned that, at present, the Chinese stars are reference to the international standards, national night places relevant provisions of China's construction and administrative measures for the assessment of standards and certification, the future will be in accordance with the standards concerned the night to protect the work and submitting applications to the International Association for the night, to obtain international certification.
