What is the ranking of negative oxygen ion content in China?

National ranking of negative oxygen ion content:

First place: Bama, the content of negative oxygen ions is as high as 50 thousand /cm? ; Second place: Huguangyan, with negative oxygen ion content as high as 65438+100000 /cm? ; Third place: Qiandao Lake, with 62,000 negative oxygen ions /cm? ; Fourth place: Jiangxi Yangling National Forest Park, with the highest negative oxygen ion content of 654.38+0.9 million /cm? .

1, Bama negative oxygen ion content is as high as 50,000 /cm?

Bama Yao Autonomous County, which belongs to Hechi City, Guangxi Zhuang Autonomous Region, is located in the northwest of Guangxi and is known as "the hometown of longevity in the world-the holy land of China". The average content of negative oxygen ions in the air here can reach 50000 /cm? It is dozens of times higher than the average inland city, which is one of the reasons why many centenarians in Bama Changshou Village live longer.

2. The negative oxygen ion content of Huguangyan is as high as 654.38+ 10,000 /cm?

Zhanjiang City, the southernmost tip of Chinese mainland, southwest 18km. It is a scenic spot with Mar volcano landform as the main body, coastal landform, tectonic geological landform and other geological relics, and it is also the only Mar Lake in China. Strangely, there is not a leaf on the lake, and the lake has not risen or fallen for thousands of years.

3. The content of negative oxygen ions in Qiandao Lake is 62,000 /cm?

Located in Chun 'an County, the western suburb of Hangzhou City, Zhejiang Province, with a lake area of 573 square kilometers, it is named after 1078 sandy green island in the lake. Its water visibility is maintained at 9-65,438+02 meters all the year round, which is a national first-class water body and is known as "the best water in the world".

4. The maximum content of negative oxygen ions in Jiangxi Yangling National Forest Park is 1.9 million /cm?

Located in Chongyi County, Ganzhou, Jiangxi Province, the forest coverage rate is 96.8%, and the subtropical virgin forest is intact.
