Is Ding'an Cold Spring still open now?

Ding'an Cold Spring was temporarily closed during the epidemic, but during the May Day holiday in 2020, it has officially reopened to the public. As the weather gradually warms up, more and more guests come to Ding'an Cold Spring. Tourists like to come here, firstly because Ding'an Cold Spring can bring people a wonderful cooling sensation, and secondly because they can also enjoy natural fish therapy in Ding'an Cold Spring.

Jiuwentang Cold Spring is located in Jiuwentang Village, Longmen Town, Ding'an County. It is 73 kilometers away from the provincial capital city Haikou to the north and 32 kilometers away from Qionghai City to the east. It is connected to the Hainan Island East Expressway through two provincial highways, and is 20 kilometers and 32 kilometers away from the "Huangzhu" and "Qionghai" exits of the expressway respectively.

Jiuwentang Village is a distribution area of ??late Pleistocene volcanic rocks. It is a volcanic platform landform formed by eruptions more than 10,000 years ago. The volcanic rocks are exposed and the roads are rugged and difficult to travel.

The edge of the volcanic platform is a steep slope with a height difference of about 10m and a certain slope. It is made of volcanic rocks and becomes the front edge landscape zone of the volcanic platform. There is layered volcanic peat buried in its lower part, which is formed by volcanic lava flow and buried swamps. The peat is gray-black and thin. Bounded by Paddy Field Valley, the east side is the distribution area of ??Middle Pleistocene volcanic rocks, which were formed more than 700,000 years ago. The surface has weathered into red soil, forming two completely different landscapes.

In the exposed volcanic rock areas of Hanlin, Longhe, Lingkou and Longmen Town in Ding'an, the volcanic rock fissures and holes are developed and the continuity is poor; coupled with the lush vegetation, the temperature of the groundwater supplied by rainfall infiltration is not easy to change, and the original temperature is retained. Rainfall water temperature. According to the naming standards of mineral springs, mineral springs with a water temperature higher than 32 degrees Celsius are called "hot springs", while those with a water temperature lower than 25 degrees Celsius are called "cold springs".

In tropical areas like Hainan Island, the underground water temperature is generally 27°C, while in the Jiuwentang area the groundwater temperature is less than 25°C. This is a new discovery of underground water temperature. Volcanic cold springs are formed on the edge of the volcanic platform. Jiuwentang Village in Longmen Town is the cold spring with the largest volume of volcanic water in Hainan. It has more than ten springs and a daily self-flow of 40,000 cubic meters. It is currently the volcano with the largest flow in China. Cold spring.

Jiuwentang volcanic cold spring water is colorless, odorless, clear and transparent. The water temperature is 23℃~25℃ all year round. It is cool in summer and warm in winter. It is sweet and delicious. It meets the requirements for drinking natural mineral water and is sodium calcium bicarbonate. Magnesium-type low-mineralized metasilicate cold springs containing high selenium and germanium have very high health-preserving and health-care functions. Because the cold spring is rich in selenium and germanium, it has strong health care functions. "Germanium" can promote the production of antibodies, as well as anti-tumor, anti-lipid peroxidation, anti-aging and other effects; "Se" can help protect cell membranes and improve immunity, prevent cardiovascular disease and anti-aging; "Metasilicic acid" It can soften blood vessels, prevent and treat cardiovascular diseases, and increase people's life span.

There is a thin layer of peat soil at the bottom of the Jiuwentang volcanic rock. Peat is layered and contains sand. The volcanic peat from the lower part of the cold spring was taken for effective state analysis. The results showed that the pH was 5.3, the metasilicate was 107.8mg/L, the strontium was 2.26mg/L, and the selenium was 0.0035mg/L. It has good mud therapy value.
