Qilihai National Wetland Park is located in Ninghe County in the northeast of Tianjin, covering an area of about 10,000 mu. It is a national AAA-level tourist attraction. In 1992, it was approved by the State Council as a national nature reserve for ancient coasts and wetlands. It is also the only national nature reserve in my country where ancient coasts and wetlands are located in the same place. It is the largest back garden of Tianjin and was rated as one of Tianjin's eight characteristic tourist attractions in 2009. Tianjin has 235 species of birds in 17 orders and 48 families, and Qilihai has 182 species in 16 orders and 39 families; Qilihai has three treasures: silver fish, purple crabs, and reeds. Reeds release a large amount of negative oxygen ions every day. According to experts' calculations, the content of negative oxygen ions in Qilihai is 3,000 per cubic centimeter, which is dozens of times higher than that in the central area of a large city. It is known as the "Kidney of the Earth". The biggest feature of Qilihai's natural scenery is the word "wild": wild flowers, wild grass, wild birds, wild scenery, wild feelings, wild fun, fresh and beautiful, with its own charm. The scenic area is composed of an 8-kilometer wetland corridor, a 4-kilometer wetland wooden plank road and 6,000 acres of pristine wetlands. The 8-kilometer wetland corridor is divided into two areas, the east and west. The east area is a slow-living area with a fun fishing area, an animal science exhibition hall, a cruise ship dock, a mountain gate, a cable bridge, a wedding photography base, a Dutch windmill park, and a water barbecue pavilion; the west area has a historical folk sculpture display corridor, a wetland plant display area, a water and sand expansion area, a children's playground, a 3D fantasy castle, a crab fishing pond, a flavor food street, and a water stage; along the 4-kilometer wetland wooden plank road, there are seven-color flower islands, bird-watching platforms, racecourses, wetland self-driving boats, wetland botanical gardens, fun zoos, wetland live CS, wetland off-road karts, rare bird paradise, lavender island, archery range, hot air balloon sightseeing, Qilihai native plant display area, and bird science corridor. You can take a luxury Chinese-style pleasure boat to sightsee in the thousands of acres of pristine wetlands, or take a sightseeing electric car to see the historical folk sculpture display corridor, or ride an environmentally friendly bicycle to enjoy the sea of flowers and experience the slow life in the wetland. Qilihai National Wetland Park integrates ecological protection, environmental education, and wetland tourism. It has become another tourist highlight in Tianjin. It has important significance and irreplaceable role in carrying out green environmental protection education, advocating low-carbon life, developing ecotourism, promoting sustainable economic development and the balanced coexistence of man and nature.
