Wetlands are known as the kidneys of the earth,
For purifying water quality,
The role of improving the water environment is unquestionable.
Take Dianchi Lake, for example,
From January to May this year,
The overall water quality of the whole lake remains class IV.
How much of a role do wetlands play in this?
Restore wetlands and protect Dianchi Lake
Wang Yu, chairman of the Local Nature Experience Center in Xishan District, Kunming City: "It (reeds) is particularly water-tolerant and fertile-resistant, and it absorbs the water fertilizer in this area, we say organic matter, after absorption, it grows very vigorously, which reduces the organic matter carried in the water, that is to say, purifies our water." ”
Wang Yu's main job is to carry out nature education, which requires a lot of knowledge reserves, in this regard, Wang Yu can not work less, and now, when it comes to wetlands, she tells a lot of family treasures.
Wang Yu, chairman of the Local Nature Experience Center in Xishan District, Kunming City, said: "Water rich in organic matter, when it reaches the tree, it becomes nutritious water, it is absorbed by the roots, and finally becomes the energy of the tree, so it actually plays a second role, it can purify the water." ”
As a native of Kunming, she has more feelings for Dianchi. Recalling the Dianchi Lake in those days, Wang Yu was very emotional.
Wang Yu, chairman of the Local Nature Experience Center in Xishan District, Kunming City: "At that time, from the seal pond to take a boat along the Daguan River into Dianchi Lake, at that time Dianchi Lake was still very beautiful, along the way you can see the mountains and see the lake, but after a section of time in the middle, there will be a factory place, there will be water like being dyed, such a polluted situation, at that time slowly began to hear, Dianchi Lake is polluted can not go down to swim." ”
In response to the pollution of Dianchi Lake, a long period of treatment began. Around 2008, long-lost ecological wetlands appeared around Dianchi Lake, playing a role in regulating the water quality and improving the environment of Dianchi Lake.
Wang Yu, chairman of the Local Nature Experience Center in Xishan District, Kunming City: "For a lake like this next to the city, this wetland is really too important, because it is in the lower reaches of the city, so the whole water flowing through the city, it can pass through the wetland, in fact, it can play a purifying role, purify the buffer and then store, and then enter the lake, it is very, very important for ecological restoration." ”
At present, the treatment of Dianchi Lake has completed the reclamation of 45,000 mu of ponds and fields, 2.33 million square meters of withdrawal, and 28,000 people in the Dianchi Lake First-class Protected Area, and the restoration of the water area of Dianchi Lake is 11.51 square kilometers. The ecological functions and biodiversity of Dianchi Lakeside have also been gradually restored, forming a closed ecological belt with an average width of about 200 meters and vegetation coverage in the area of more than 80%.
Wang Yu, chairman of the Local Nature Experience Center in Xishan District, Kunming City, said: "I am also very, very much looking forward to dianchi Lake being able to return to the way we were when we were young, with blue waves of fish and shrimp full of lakes, and then going to swim in Dianchi Lake." ”

In Jinning there is a South Dianchi Wetland Park,
At the end of last year, it passed the acceptance of the State Forestry and Grassland Administration,
This is one of the two national wetland parks in Kunming.
Is there anything special about it?
Nandian Lake Wetland became a "National Wetland Park"
Walking into the South Dianchi National Wetland Park, the reporter's eyes were immediately attracted by several leisurely herons. Zhou Xiuyuan, a citizen who came to watch birds, reminded us to be quiet and not to get excited. Zhou Xiuyuan loves bird watching, as can be seen from his equipment, he said that he has been to many wetlands of all sizes, and there are many birds here.
Citizen Zhou Xiuyuan: "This wetland has at least hundreds of species of birds, the environment here is very good, including your habitat, as well as its natural ecology, I think it is particularly good, so it will attract so many birds." ”
Located in the southwest corner of Dianchi Lake, Nandianchi Wetland Park consists of the southern waters of Dianchi Lake and the shoreline of Nandianchi Lake, including the mouth of the Dongda River, the largest area in the basin of the Dianchi Lake into the lake, with a total area of 1220 hectares. Yu Bo, deputy director of the Nandianchi Lake Wetland Park Administration, introduced that this is one of the areas with the richest variety and number of wild animals and plants in Dianchi Lake, including many endangered and rare varieties.
Yu Bo, deputy director of the Nandianchi National Wetland Park Administration, said: "After the test report came out, there were 260 species of plants, 127 species of birds, and 23 species of fish, and then our wetland park happened to be on the largest migratory bird migration channel in the west, so there were also many birds, 13 colored birds came in 16 years, as well as pincer-billed storks, white eyebrows, field chickens, and purple water chickens, these four are endangered birds in the country." ”
Because of its well-preserved biodiversity, the Nandian Lake Wetland Park has also received the "Outstanding Award for Wildlife, Biodiversity, Habitat Improvement or Construction" from the International Federation of Landscape Architects. The rich biodiversity is just one feature of the South Dianchi Wetland Park. As an important part of the closed ecological belt around Dianchi Lake, The South Dianchi Lake Wetland is the largest wetland in the lakeside of Dianchi Lake, and plays a huge role in improving the water quality of Dianchi Lake.
Yu Bo, deputy director of the Nandianchi National Wetland Park Administration, said: "This place is an exchange port for water between our Dianchi Lake and the wetland, through which we enter the wetland, after the wetland adsorbs cyanobacteria, and then enter the Dianchi Lake through the time just now, the water that goes out can reach four or three categories." ”
In the 1980s, the "breakwater" built to clean up the flooded fields around Dianchi Lake was recognized as the "driving force" of the increase in pollution in Dianchi Lake. In order to protect Dianchi Lake, in 2008, Kunming launched the "four retreats, three returns and one protection" project.
Yu Bo, deputy director of the Nandianchi National Wetland Park Administration, said: "After the breakwater built in the past, fish ponds and farmland can be built, but for the treatment of Dianchi Lake, the breakwater has now been demolished, and (now) this place is a restoration and reconstruction area for us to retreat from the pond and wet." ”
The construction of the Nandian Lake Wetland Park has turned the once stinking Hegang Pond into a green home with abundant water and grass, and the villagers who have lived here for generations have become the most direct beneficiaries.
Villager: "Now the wetland is built, the environment is good, the air is good, the water quality of Dianchi Lake is slowly getting better, we work inside, the air is good, although we do cleaning work, but we are also very happy and happy." ”

Question 1: There are now 18 national wetland parks in Yunnan Province, and the South Dianchi National Wetland Park is one of the two national wetland parks around the Dianchi Lake, why build the South Dianchi National Wetland Park?
Question 2: What specifically has been done? The result?
Question 3: Wetland park is also different from the general wetland, since it is a park, there must be tourists to play, involving the rational use of wetlands, how do we deal with the relationship between protection and utilization?
In 1992, China joined the international "Wetland Convention" The title of "wetland" was introduced to China, wetland is one of the most important environmental resources on which human beings live, people protect wetlands, wetlands are also infiltrated with human civilization, bringing everyone both poetry and distant artistic conception, but also carrying people's infinite nostalgia for nature.
