Nangong World Geothermal Expo Park

　　Nangong World Geothermal Expo Park is located in Nangong Village, Wangzuo Town, Fengtai District, covering an area of 800 acres. Major attractions include: the Geothermal Science Exhibition Center, the Hot Spring Special Aquaculture Center, the Hot Spring Fishing Center, and the Hot Spring Planting & Picking Base. Future plans involve utilizing the beautiful natural environment of Nangong Garden to build a geothermal mineral therapy center.

　　In cooperation with the Beijing Institute of Geological Engineering Exploration, Nangong Village successfully developed high-quality geothermal hot spring water in October 2000. The hot spring well reaches a depth of 2,980 meters, with a daily output of 2,700 tons, a water temperature of 72°C, and rich in various minerals and trace elements beneficial to human health. The Expo Park hired relevant experts to meticulously design and implement computer-controlled management, ensuring the “one-time development, tiered utilization” of the geothermal hot spring water. First, the high-temperature water is used for winter heating; the purified medium-temperature water is used for hotels, entertainment venues, the hot spring water park, and for villagers’ fitness, swimming, and bathing; the low-temperature water is further treated for special aquaculture and fishing; and the coolest water is used for irrigation in the agricultural park. Reviewed and appraised by national geothermal experts from relevant geological and mining departments, “Nangong’s comprehensive utilization of geothermal energy has reached world-advanced levels,” earning Nangong the title of “China’s No. 1 Geothermal Village.”

　　The Geothermal Science Exhibition Center has a construction area of 3,000 m². Its first floor houses a geothermal water treatment workshop and a green agricultural products supermarket, while the second floor makes full use of modern sound, light, and electrical technology to showcase the application of medium- and low-temperature geothermal energy both domestically and globally, aiming to educate primary and secondary school students as well as the general public about geothermal knowledge. The second floor also features a visitor center that integrates rest, video recording, medical services, and communication functions.

　　The Hot Spring Special Aquaculture Center covers a construction area of 5,000 m², with four indoor and two outdoor hot spring breeding workshops, primarily engaged in the breeding of fry and adult fish of rare, specialty, high-quality, and new aquatic species, as well as tropical ornamental fish.

　　The Hot Spring Fishing Center has a construction area of 12,000 m². The first floor includes five regular fishing ponds, two premium fishing ponds, as well as one rare touch-fishing pond and one spear-fishing pond—both seldom seen in China—and a goldfish fishing pond designed for children. The addition of VIP and regular rest areas, along with dining services on the second floor, greatly facilitates fishing enthusiasts and sightseeing visitors.

　　The Hot Spring Planting & Picking Base spans 350 acres, mainly dedicated to the cultivation of specialty vegetables and flowers, as well as the picking of various seasonal fruits, offering a strong rural ambiance. The establishment of a 20,000 m² intelligent greenhouse has further enriched the overall functionality of the base.
