Why is Guidong an immortal summer resort and an isolated health paradise?
It is said that Guidong is an immortal summer resort and an isolated health paradise, but why Guidong won this honor is unknown to many people. Let's do it one by one.
Guidong county belongs to the humid monsoon climate in the middle subtropical zone. Its main features are no heat in summer, no cold in winter, warm and humid, and distinct seasons, enjoying the reputation of "natural oxygen bar and natural air conditioner". The average sunshine for many years 1440.4 hours and the average temperature 15.8℃, in which the average temperature in summer is 23.6℃, which is 4.4℃ lower than that in Changsha. The annual precipitation 1742.4 mm, the average frost day is 29. 1 day, and the frost-free period is 249 days. The temperature difference between day and night is large, and there are obvious regional differences due to different topography and altitude, forming a microclimate area of "one mountain with four seasons and ten miles of different days".
China has certain criteria to judge whether it can be called a summer resort. For example, the China Meteorological Bureau and other relevant departments have some related evaluation indexes on the altitude, temperature, humidity and air of summer resorts. Relevant indicators of Guidong are as follows:
1 summer resort. Altitude index: 500-2000m.
The peaks in eastern Guangxi are towering and overlapping, with an average elevation of 88 1 m. According to the experimental study of physiology and health, the most suitable altitude for human survival is 500 ~ 2000 m m, and the altitude in eastern Guangxi is just in the best altitude section of this most suitable interval.
2. Average temperature index in summer: 22-25℃
According to the research results of scholars at home and abroad, the most comfortable temperature in summer is 24℃, because the normal body temperature is 36℃-37℃, and the product of this body temperature and the golden ratio of 0.6 18 is exactly 22.4℃-22.8℃, and under this environmental temperature, the physiological function, life rhythm and other metabolic levels of human body are in the best state.
According to the statistics of China Meteorological Bureau, the average temperature from June to September in Guidong for many years is: June: the highest temperature is 27.19; Minimum temperature:19.61; July: Maximum temperature: 29.75; Minimum temperature: 20.56; And August: the highest temperature: 29.36; The lowest.
3. Summer humidity index: 45%~65%
Besides temperature, humidity is also important. When the humidity is greater than 95%, people feel very sultry, sweat on the body surface is blocked, heat dissipation is poor, and the skin feels wet and sticky, making it difficult to breathe, which leads to people having to open their mouths to gasp. At the same time, my mood began to become boring. Of course, too low humidity is not good, too dry environment is easy to cause skin peeling. The most suitable humidity for human life is 45%~65%. In summer in eastern Guangxi, except for rainy days, the air humidity is just in this range.
4. Health and isolation air index: excellent, sandstorm: 0.
The annual excellent rate of air quality in eastern Guangxi is 100%. Sandstorm: 0. The average content of negative oxygen ions in the county is 25272 /cm? , the highest instantaneous value 150000 sheets /cm? Set a world record for the county with the highest negative oxygen ion content in world record association. Negative oxygen ions are "air vitamins". The higher the concentration, the fresher the air will be. According to the report of the World Health Organization, diseases can be prevented and treated when the concentration of negative oxygen ions in the air exceeds 0/0000 per cubic centimeter/kloc. When the concentration is 400 to 1000 per cubic centimeter, it can maintain the needs of human health; When it is less than 50 per cubic centimeter, it may induce diseases. According to the regulations of the World Health Organization, the standard concentration of negative oxygen ions in fresh air in a place is not less than 1 0,000 ~1500/cm3, while the value of negative oxygen ions in Guidong greatly exceeds this standard 10 times, so it is also recognized as "the county with the highest negative oxygen ion content" by Guinness World Records, which is a veritable health preservation.
5. Coverage rate of healthy isolated ecological forest:
Throughout the year, birds are singing and flowers are fragrant, mountains are green, ancient trees are towering, clouds are lingering, springs are tinkling, streams are gurgling, virgin forests are dense, and the forest coverage rate reaches 85%, ranking first in the country. More than three times higher than the national average.
6. The beauty of health and seclusion:
There are many mountains in eastern Guangxi. There are mountains in the mountains, mountains in the mountains, mountains in the mountains, and mountains are connected and surrounded by mountains. There are 57 peaks 1 in the county, including more than 300 peaks above1m and more than 2000 peaks above 10. Magnificent and steep, with an altitude of 20665438+. Hundreds of mountains are named after immortals, and Guidong ranks first in the world. Why are we looking for them everywhere? Being in Guidong, Guidong is simply a panoramic ink painting: blue sky and white clouds, small bridges and flowing water, scenery everywhere, painting everywhere, people roaming in the painting, and you are the person in the painting.
It's not cold in winter and not hot in summer. The average summer temperature in Guidong County is 5- 10 degrees lower than that in other large and medium-sized cities. It is a well-known "health paradise, summer resort and natural air-conditioned oxygen bar city". Guidong has become the first choice for more and more donkey friends and elderly migratory birds for summer vacation and leisure. Of course, it's not surprising that we have won the honorary titles of "Best Eco-tourism Demonstration County in China", "Deep Breathing Town in China 100", "Beautiful Land Climate in China" and "Best Summer Tourism County in China".
Therefore, as the saying goes: "The mountain is not high, and the fairy is famous." In Guidong, Hunan, hundreds of high mountains are named after immortals. Chenzhou is the 18th blessed place in the world, Guidong is a fairyland on earth, and China is the fairy capital!
