The islands are scattered all over the place, the lake is rippling with blue waves, and a pair of mandarin ducks are looking for food and rest... Entering the Zhanghe National Wetland Park in Jingmen City, Hubei Province, the view in front of you is very refreshing. "More than 10 years ago, there were many chemical plants here, and the water environment was seriously polluted," said Chen Hui, head of the Zhanghe National Wetland Park Protection and Management Station. In recent years, Jingmen has strengthened its ecological environment management, closed down a number of polluting enterprises according to law, successively removed all breeding cages, closed down restaurants and restaurants in the drinking water source protection zone, and included 120000 mu of forest land around Zhanghe River into the key public welfare forest protection project. Targeted policies and multiple measures were taken simultaneously, and the protection and restoration of Zhanghe Wetland achieved remarkable results. In 2014, Zhanghe Wetland was approved as the National Wetland Park and listed in the National Important Wetland List in 2020. "Zhanghe Wetland integrates protection and conservation, science popularization and education, scientific research and monitoring, and wetland ecological tourism, as well as the functions of drinking water source and irrigation water source." Sun Zujun, deputy director of Jingmen Municipal Forestry Bureau, said that with the deepening of environmental remediation, the water quality in Zhanghe reservoir area has been continuously improved, reaching the national Class II standard for surface water, the "giant panda in water" peach blossom jellyfish appears year after year, and the Chinese merganser and other national first-class protected animals have become frequent visitors. In the Overseas Chinese Town National Wetland Park in Shenzhen, Guangdong Province, the breeze blows the water, and the mangroves on the shore are lush and green, spreading the whole shoreline. Beside the trestle, clusters of mangrove seedlings float on the water. "This is an ecological floating bed, supporting mangroves and other aquatic plants. Birds can live on it, aquatic plants grow on the floating bed, and developed roots absorb the rich nutrients in the water." The staff of the wetland park said, "Algae in the root system become the food of zooplankton, and fish also have zooplankton and other food, forming a micro-ecosystem to repair the water body and purify the water quality." Scientific protection and restoration make this wetland located in the downtown become the "green jade" in the city, and play an important role in improving the urban ecological environment and protecting biodiversity. At present, more than 1400 species of animals and plants have been recorded in the wetland of OCT, and 26 species of birds under national key protection, such as black-faced spoonbill, osprey and white-bellied harrier, are inhabited. China has a vast territory, from the cold temperate zone to the tropics, from the coast to the inland, and from the plain to the plateau and mountainous areas, with wetland distribution, rich types and vast area. In the past 10 years of the new era, China has continued to strengthen wetland ecological protection and restoration, and made historic achievements. Over the past 10 years, China has allocated more than 16.8 billion yuan of central financial funds, implemented more than 3400 wetland protection projects, repaired a number of degraded wetlands, and improved the ecological conditions of degraded wetlands. At present, China's wetland area has reached 56.35 million hectares, and a wetland protection system based on national parks, wetland nature reserves and wetland parks has been initially established. Of the 43 international wetland cities in the world, China accounts for 13, ranking first in number. There are more and more pleasant scenery with fish swimming and gulls and herons. In the Minjiang Estuary Wetland of Fuzhou City, Fujian Province, the mangroves are swaying in the sea breeze, and the bird song is clear and sweet. The local government has vigorously carried out the project of "returning the recuperated to the wet", carried out the project of rebuilding the sluice, setting up the plant isolation zone, restoring the vegetation diversity, etc. The wetland ecological environment has continued to improve, and the recorded increase of wild animals, plants and aquatic organisms
