Reporter squatting point 丨 "advancement and retreat" in the protection of biological diversity

In the midsummer season, in the Swan Lake International Slow City on the south bank of the Yellow River, 10,000 acres of lotus ponds spread in front of them. Take a boat from the dock from the dock. Within a few minutes of boat trip, Ichu, Yelul, and Egret appeared one after another.

Biological diversity is the core and spirituality of the ecosystem, and the purpose and direction of ecological environmental protection. From the former Yellow River Shenshachi to the Bird Park today, it relies not only to the magical ghosts of nature, but also the artificial ingenuity of it carefully. In the process of building a beautiful Shandong in harmony between the builder and nature, what role the person should play, how to find a balance between progress and retreat, and try to give answers during the exploration.

Retreat

Drive through the Nature Reserve of the First Birds of Huangji Qingqu, Boxing County, and the more "desolate" -the core area and the buffer area are inaccessible, overlooking the distance, and only the rich vegetation stretches towards the distance with the water bubbles.

"'Desert' is for people. For plant animals, it is very lively here." Following the direction of Wei Haifeng, the captain of the Pangjia Squadron of the Boxing Branch of Binzhou Ecological and Environment Bureau, the reporter saw a group of wild ducks And egret. As soon as people approach, they fly away.

This nature reserve is an accident of "inadvertently inserting willows". "In the 1980s, it was once a Shenzhachi in the lower reaches of the Yellow River. The purpose of building Huang Jiqing canal is very clear. It requires a broad area to slow down the water flow. The sediment can be precipitated, and then the water supply to Qingdao." Wei Haifengfeng. Tell reporters.

People retreat, the sand sinks, the reed is long, the bird enters. While ensuring water supply, the longer the plants, the more the pheasant and the rabbit, etc., also gradually appeared on this land. In the early 1990s, Shensha, which gradually became rich in species, became a county -level nature reserve, followed by the intensity of "people retreat" further. "In addition to the west of the reserve, there are two villages in Xindian Village and Liu Wangzhuang Village. The villages in the east are basically relocated and moved to the town government resident. This is to reduce human activities and leave nature to leave the nature that is not disturbed. The space comes. "Wei Haifeng said.

Today, the once barren sandy land attracts a large number of migratory birds every year to inhabit and reproduce here, becoming one of the important bird migration nodes in the Yellow River Delta region. "According to the survey, there are 136 species of 101 of the 48 subjects in the 48 subjects in the protected area; 149 species of 28 meals and 54 families in the wild vertebrate, including 24 species of wild animals in the province, mainly birds." Boxing County Natural Resources and Planning Gao Tao, a staff member of the forest grass wetland stock, introduced.

Dongping Lake more than 200 kilometers away, the key step of ecological restoration is also stepped on the "retreat". The construction of ecological civilization must not be seen that the indicators are not seen. Dongping Lake, as the only important flood storage area in the lower reaches of the Yellow River, an important hub of the South -to -North Water, and an important node of the Beijing -Hangzhou Grand Canal, it is self -evident to do the importance of ecological protection. Chen Qilin, deputy head of Dongping County, told reporters: "In recent years, Dongping has strongly carried out the nine major rectification operations of Dongping Lake's ecological environment. 'Ship, in -depth control of the environment, the environment, and illegal buildings of the environment, the environment, and illegal buildings, and the construction of the ecological isolation zone of the lake is 74 kilometers. The appearance of the lake area is refreshed. " , Attracted many rare wild animals. The survey shows that there are 679 species of plant resources in Dongping Lake Nature Reserve, 786 wild animals, 3 types of national -level protected wildlife, and 20 national -level protected wildlife. Biological diversity protection has achieved significant results.

Help a while

Almost every person who has made a hand -over with wetland management has a difficult "running -in period" that explores the spleen of the aquatic plant. "Now the fungus, Huangpu Pu and other plants in the wetland are manually cited and carefully selected. They have developed root systems and good water purification effects." Song Qiang, director of the Huantai Branch of the Environment Bureau, introduced the plants in the wetland one by one to reporters.

The Matham Lake is the only natural lake in the middle reaches of the Xiaoqing River, known as the "kidney of the Xiaoqing River". With the rapid development of industrialization and urbanization, the water quality of the water body and water of the water, the dragon river, Wuhe, and the filial piety rivers of the Maria Lake was severely contaminated. Matham Lake lost the water supplement source. Decreasing year by year, the ecological environment of Ma Tahu Lake was severely damaged.

Do you do a good job of sewage discharge and breeding emissions of corporate enterprises, can Ma Ta Lake suddenly turn around? Can't: For those ecosystems that have been destroyed, after the exit of human development and construction behavior, it is only repaired by the nature of the nature. It takes time and slow. "At this time, the role of a person is required to go further, and help in the key link." Song Qiang said.

The Thailand is planned to build artificial wetlands at the rivers entering the lake entrance, important point source discharge port, tributaries and tributaries, and the lower reaches of the sewage treatment plant. The recovery, near -natural artificial wetland construction, returning farmland to the lake mine resumed green, and comprehensive governance of the Maya Lake Basin to improve the ability of flood prevention and storage, water supply, and water quality in the lake area.

Huagou's artificial wetland is located at the mouth of the Zhulong River entering the mouth of the Maya Lake. "The water that enters the wetland is mainly the water after the sewage treatment plant is treated, which is lower than the three types of water in the three types of water in Maya Lake. If you do not manually intervene, let the water flow in, and the water in Matsha Lake is difficult to clear." Song Qiang introduced it. Essence In this artificially created wetland, the water flow first flows into the stranded pond for initial precipitation filtering, and then enters the submarine wetland to remove 80%of the pollutants. Finally The grass, black algae, fox tail algae, bitter grass, etc. further purify. After one month after turning around, the four types of water can be improved to three types of water, which continues to hydrate for Maya Lake. Through positive and standardized artificial intervention, the biodiversity of Ma Ta Lake is rich. Today, Mahahu Lake, shaded and bird -language flowers. At present, more than 70 species of large poultry such as Zhendan crow, water duck, egret, white crane, and heron have been found in wetlands.

Harmony symbiosis is not a long view or participation

Starting from the Plum Pier of Dongping Lake, half an hour later, they arrived at the hinterland of Dongping Lake. On the open water surface, the sporadic can see the bird's rising figure. Chen Changlun, the president of the Dongping County Bird Watching Association, who is familiar with the temperament of the green head duck, led the reporter to a shore near Houtun Village, Dongping Lake. "This summer, for the first time, we observed the mating and reproduction of Qingtou Qian Ducks in Dongping Lake.

In the winter of 2019, the global extremely critical species and national first -class protection of animal green head duck were first observed by the winter in Dongping Lake. In March of this year, Dongping Lake once again recorded more than 1,500 green -headed ducks.

Because of this group of rare birds, Chen Changlun had a heavy identity: In May this year, Shandong set up a green -headed duck maintenance observation station in Dongping Lake, and Chen Changlun became the head of the green head duck maintenance observation station. "It turns out that we are just looking at a distance. We do not interfere or participate in the lives of birds. Now we have to do one of us -moderate protection." Carry out wildlife rescue, artificial breeding wildlife, expand the number of populations, maintain a healthy and scientific ecosystem, and keep the food chain stable.

As soon as the maintenance observation station was established, the "carpet type" census of Dongping Lake Qingtou Qingsheng Duck was launched in combination with Qufu Normal University. "Green -headed duck was a migratory bird, but through our census, we found that 346 green -headed ducks did not migrate north this year's breeding season this year, becoming a 'stay bird' on the lake." Chen Changlun said. In early July, the first batch of 14 green -headed duck families hatched chicks, the most 12 chicks, and the least 4. The second batch was observed to upgrade their parents with 4 couples, and 26 young birds were observed.

Mastering these is not only for viewing, but also to protect. "For young birds, we must prevent natural enemies. We monitored and found that there are weasel feces near the green head duck habitat. The stool is twisted with hands and placed in the water. Young birds are eaten. After discovering this, we formulate a plan to drive weasels, etc., and protect rare birds more accurate and better. "

By 4:30 in the morning, on the first ray of Xia Guang, Chen Changlun began a new day of "bird patrol". "When I first started shooting birds 8 years ago, the birds on the lake were very single, mainly because of the bearded gulls. Now, there are flowers, ducks, green -headed ducks, red -headed ducks in winter, and small corders, Zhendan crows in summer The birds and water phoenix feel happy when they look at it. The environment is good. The birds are coming. All we have to do is to let them come and leave. "Chen Changlun said.
