The youngest wetland ecosystem of the warm and temperature zone in my country grows like this

The National Nature Reserve of the Yellow River Delta is known as the "Bird International Airport". This is an important stop, overwintering place and breeding ground for East Asia-Australia and West Pacific Birds. There are 25 types of birds and 65 national second -level protective birds, and 38 species of bird species exceed 1%of the world's number. They are one of the largest areas of 26 important wetlands in China.

Behind bird diversity is rich in biodiversity. There are 685 species of various plants and 1,630 species of various plants in the protected area. ecosystem.

Oriental white 鹳 intuitively reflects the effectiveness of the wetland ecological recovery

On August 21, the students participating in the Yellow River Basin and the Habitat Investigation and Training Meeting of the Yellow River Basin conducted a group of field internships in groups. The car drove across the Yellow River and drove deep into the protected area. On both sides of the embankment are different scenery. On one side of the water rippling, the reed swaying with the wind; As soon as the car stopped, I saw that there were two oriental white pupa wings on the beach.

Oriental White Cycles are national first -class protected animals and are listed as endangered species by the World Nature Protection Alliance (IUCN) red species. According to information, the breeding areas of Oriental Baiya are usually in high latitudes north latitude to high latitudes north latitude. The Sanjiang Plain Basin distributed in the Sino -Russian border is mainly in the middle and lower reaches of the Yangtze River in China. No breeding records. In 2003, for the first time in the Yellow River Delta region, the East White Cycling breeding population appeared, and it was successful for the first time in 2005, and then the population increased year by year. Now it can be seen all year round. It has become the world's largest breeding place in the world, and Dongying City was also identified as "the hometown of Chinese Oriental White Baiji" by the China Wildlife Protection Association in 2010.

"Oriental white ravioli is the flagship species of wetlands, and is a species of the ecological quality of wetland." A popular science information about the science popular science of the Yellow River Delta's characteristic birds was written. At the Yellow River Basin Water Bird and Habitat Investigation and Training Meeting on August 20, Dr. Wang Antong, the National Nature Reserve Management Committee of the Yellow River Delta, Shandong, mentioned a set of data when introducing the progress and practice of the investigation and practice of the Yellow River Delta waterbird and habitat. In 2022, the Oriental White Breeding 152 Nests 470 Young Birds, cumulative breeding of 2748 young birds.

Dongfang Baiyu from scratch, from passing to settlement, from the built nest breeding here, to the increase in population and the number of chicks, which is closely related to the restoration of the wetlands of the nature reserves, or this intuitively reflects the intuitive reflection of it The effectiveness of the wetland ecological recovery in the Yellow River Delta region. The papers of Shan Kai and Yang Changzhi and others in the Management Committee of the Shandong Yellow River Delta Nature Reserve "The Principles, Methods and Practices of Wetland Ecological Recovery in the Wetland of the Yellow River Delta Nature Reserve" explained: Born vegetation began to grow in large areas. Fish living in wetlands and amphibians dependent on wetland survival began to reproduce. These factors provided water, food resources and habitat conditions for the breeding of Eastern white ravioli, and have the demand for reproduction. "

Fix the ecology with ecological methods

Earlier in the early years, the Yellow River Delta region was not so beautiful and rich in species.

"The Yellow River enters the sea in the Yellow River Delta Nature Reserve, the Haihe River remittance, and the sediment deposition, forming a new wetland ecosystem of the Yellow River entering Haikou." The paper "Principles, Methods and Practices of Wetland Ecological Recovery in the Yellow River Delta Nature Reserve" road. This new wetland ecosystem is young, fragile, and unstable. According to Shan Kai's relevant information about the ecological wetland of the Yellow River mouth, due to the lack of freshwater supply, seawater transpiration, and seawater pouring erosion, the wetland has degraded.

"In 2002, the Yellow River first implemented a water -adjustment test. With the help of the favorable conditions of sufficient water volume during the water adjustment of the Yellow River, 3300 hectares of the wetland recovery project was implemented in the current Dawenliu Management Station on the south bank of the current Yellow River Road. Build fresh water to build a dam, and the surface runoff and freshwater circulation are restored through the canal, connecting the gate, and the leakage sluice. Essence

According to reports, by quoting the Yellow River water, the area of ​​freshwater wetlands has continued to increase. Wetlands with light plates, mullets, and alkali pengs are replaced by reeds and mugs as the main landscape wetlands. Area. Over the years, the protected area has used ecology to repair the ecology, with a total of 72,500 acres of wet farmland and wet farming, recovering the beach, 241 kilometers connected to the water system, 47,000 acres of salt -alkali and seagrass beds, and repairing the wetland area of ​​188 square kilometers.

"With the management of the protected area, it continues to improve and repair the function of wetlands, and to repair river grass and beaches through artificial intervention to repair vegetation and greatly improve ecological function. As much, naturally enriches bird's feeding resources, "said Zhang Xitao, senior engineer of Huanghekou Management Station in the Yellow River Delta National Nature Reserve in Shandong, said," The method of hydrating through wetlands has shallow water, deep water areas, and land water areas. , That is, the land part, there are all kinds of birds in this case. "Bai Town Ding Hong'an was taken

Not only the oriental white ravioli, the birds have been established from 187 at the beginning of the reserve to increase to 371 species. Here are still the world's second largest breeding place in Black -Mouth Gulls, the world's second largest overwintering place in the world, and the largest East Asian population in the rolling feathers. Migration stops. Among them, the Huanghekou Management Station located on the north bank of the Yellow River is an important migration place for a variety of cranes such as red -crowned cranes, white cranes, and gray cranes. Dawenliu Management Station in the protected area records a variety of rare birds such as Black -mounted gulls, green -headed ducks, and Chinese autumn sand ducks. The protected area is known as the "Bird International Airport". This is an important stop, overwintering place and breeding place for the migration of East Asia-Australia and Western Pacific Birds. There are 65 species and national second -level protective birds, and there are 38 species of bird species exceeding 1%of the global quantity. It is one of the largest number of the 26 important wetlands along the coast of China.

Behind bird diversity is rich in biodiversity. There are 685 species of various plants and 1,630 species in the protected area. Water surface, beach coating, vegetation, water birds ... biological enrichment forms different landscapes in different seasons, showing the beauty of ecology.
