When the cold came out, the coolness of the city of changwu in yanin province became stronger. Despite the autumn, the town of zhang gutai, located in the northern part of mongwu district, is still green, with the autumn wind blowing through and the pine thawing。
“look out the window, a green plant planted in the garden of the people's house, which is a sapling. Zhang gutai, the country's largest seedlings, has increased income from raising the seedlings.” on the way to the integrated observation test base for the sanctuary sanctuary ecosystem, the presenter enthusiastically presented the view along the road, “when, once, the mobile dunes ran away from the local population again and again, now the dunes are fixed, the ecology is ready and the people are back”
Good days are inextricably linked to good ecology. Today, the forest area of zhangwu county has increased from 180,000 acres to 2. 12 million acres in the early days of the new china, increasing forest cover from 2. 9 per cent to 31. 47 per cent, effectively blocking the southern invasion of korzhunsha, erecting an eco-security barrier on the border with liaomon, and writing a great green desert legend on china's sandproof history。
Behind the legend is the persistence of several generations of forestry scientists who have taken root and committed themselves to fighting the sand。
On 3 august, the convergence of the exercising war in koljan, a well-known dakshah, was convened in liaoning. This was the pilot site for the integrated observation of the pine-consolidated sarin ecosystem in liaoningshad. Cao yin
In the face of bad ecology, i want to cure the sand
A piece of the “big desert flow” stone, which enters the institute for governance and use of sands in liaoning province (hereinafter “the sands house”), located in the town of zhang gutai, chum wu county, is an infinite source of imagination. The tablet, which was set up by 380,000 people in chum wu county in 1988 for sand, expresses great respect for the successive generations of scientists in sandland who struggled to prevent sand and create a happy home。
In 1952, the liaoxi people's government established the liaoxi forestry pilot station (which is the front of the sand) in zhang wu county, located in sandshi, to carry out a pilot study on silviculture. This was the first scientific institution in the country to combat desertification。
At that time, the natural conditions in the tung fu area were very poor. Every day in the wind, the dust of the zhang tsar flows, swallowing fields and pastures, burying houses and blocking traffic. Approximately 40 per cent - 70 per cent of agricultural land is subject to sand-throwing pressure each year, with less than a pound of grain production。
Liu bin, the first director, arrived in chang gutai on the first day and the farmer pointed at the shivering window of wind and sand, and said, “this is a year of wind, from spring to winter, and dust and dust to the sun.” the following morning, liu bin's door had been blocked by the sand and was unable to be pushed. The colleague climbed out of the window and set up sand piles at the door with a shovel。
In addition to causing environmental catastrophes in the local environment, the storm has also spread at an alarming rate to the south-east, under the influence of the monsoon, directly threatening the ecological environment and territorial security of the north-west and even central cities of liaoning。
The sand was solidified to prevent the undisturbed south of the corginsa, and ultimately to be planted。
In the spring of 1953, scientists experimented with seedlings by seeding pines, which were naturally distributed in northern parts of the shenzhen and huron belshad; in 1954, 2,000 oil pines were planted, resulting in only two live births; in 1955, they travelled far to the original forests in huron belshad, where they found the country's only remaining raw sand pine pines, where 5,000 pine seedlings were planted and made a living, and built the country's first s pine artificially solided sand forest, setting a precedent for its seeding。
In 1978, a national science congress award was awarded for safrost forest technology。
Over the decades, generations of scientists have struggled to address the causes of the degradation of swarm pine plantations and the scientific and technical difficulties of prevention and control, and have found scientificly constructed and rationally operated ecological regulation measures that provide technical guarantees for the operation of safrole pine forests and the enhancement of their ecological functions。
At present, the sandhouses have built 2,620 hectares of scientific research, become the country's only technology research centre for swarm pine engineering, set a precedent for artificial sand management by seeding safrost, create an artificial forest farm with zhang gutaiwan, explore integrated sand management with shrub mooring, mechanical sand barriers and front-loading, winding, and batch management, and are listed as one of the country's three main sand laws, filling the gaps in the saloon sand management in china。
Forestry research has borne fruit
By the 1980s, 250,000 acres of artificial sand stabilization had been promoted in and around the province of sand and 300,000 acres of masonry pine。
The technology has been compromised, but the pace of sand-control efforts by scientists has not stopped, and the dissemination of technology and radiation throughout the country is a common aspiration of researchers in the sand。
Scorpion pines have the advantage of drought, cold and infertile. As a result, technologists have stepped out of their training to build bases in the o-han flag of inner mongolia, the yongjiang district of heilongjiang, qinghai sining and shashi zirin, among others, to promote sound seed technologies for silviculture。
At present, swarms have become the main forested species in the three northern regions of the country. According to incomplete statistics, we have an area of 12 million acres of sorghum plantations, which has undoubtedly become one of the main sapling species in the construction of our “thir north” project。
The sand fields have been chosen to produce the national and provincial forested species of wushin, sandi redsine, white pines, etc., as well as the cold-resistant, drought-resistant, small diamond-drying, sand-dwelling pine pine, etc. Among them, zhuang song is fast, drought-resistant, cold-resistant, especially with no visible pests and pests, and the composite indicator is more than 20 per cent higher than sorghum, making it the green tree species of the beijing winter olympics。
These results have been widely applied at the front line of combating desertification. In the north-western region of liao, xiaomei zhang has become the main forested species, with 750,000 acres being planted in the new city alone; he has spread to heilongjiang, shaanxi and shanxi provinces。
The sand explores ways to achieve ecological restoration and to meet the growing needs of the people of the sandy region for a better life, through seeding of excellent trees, such as sandy rheumatism, sandy ointment trees, sandy alpines, etc。
The combined benefits of scientific research are increasing
A number of generations of veterans surrounded the grass, silvicultural silhouettes and built a solid green wall in the north-west of liaon, firmly preventing the sand-flowing southwards. Today, the days in the sand are over and green brings a new life to the people of changwu county。
The people of the town of gutai know this best。
In the town of zhang gutai, forest cover increased from 6 per cent in the early days of the new china to 44 per cent, and solid sarin protected large areas of agricultural land, water fields and orchards, minimizing the damage to wind and sand and increasing total food production 10 times more than before governance。
Sandhouses have passed the technique of pine seedlings to the local population free of charge, making the area of zhang zhang zhang zhuai, the country's largest seeding plant, a local rich industry. At the same time, the promotion of economic forest cultivation, such as eucalyptus, and sandy, multi-purpose forest-based business techniques and models have emerged from the path of ecological improvement, local economic development and increased income for the population。
The transformation of tung yu from poor to rich forest districts has not only brought forestry to feed agriculture, but has also brought forestry to feed the industry, as has the new municipal forest products industrial base。
Agriculture, animal husbandry, silican sand industry, wood processing and wood industry and ecotourism are all growing rapidly. Studies have shown that solid sarin, dominated by safroles, has significant economic, ecological and social benefits, with combined benefits of 7. 47 times the total investment。
In 2020, the story of the silvicultural team, “the first change in heart and oasis from desert to oasis”, was rated as one of the first “advanced developments” in the national forest grass office's implementation of xi jinping's ecological civilization。
In a new era, new weather and new practices, sandshire will continue to take on the responsibility of the rich and the rich, in a spirit of great indifference, and will do its utmost to guide the modernization of forestry in sandy areas to build healthy and rapid development. (giggling)
