In the evening of April, the golden glow fell on the continuous grassland. In the distance, groups of Tibetan antelopes and Tibetan wild donkeys sometimes bow their heads to eat and sometimes walk and run. This is the Qiangtang National Nature Reserve, known as the "forbidden zone of human life", with an average altitude of more than 5000 meters. It is also a paradise for the growth of unique and tenacious "plateau elves". Since the 18th National Congress of the Communist Party of China, as an important national ecological security barrier, the Tibet Autonomous Region has attached great importance to ecological and environmental protection, taken multiple measures to protect the ecological environment, and achieved good results. Now, a picture of "the most beautiful third pole" is slowly unfolding in the grassland of northern Tibet. "We are the watchers of this land" In the yaamu management station north of Shuanghu County, Tibet, the stove that was lit the night before yesterday has long been extinguished. As the black sheep dung poured into the stove, the house began to warm up. As the youngest caretaker of yaamu management station, 24-year-old losangrida often gets up early to make a fire. "The most commonly used fuel is animal manure, and the stove is standard in Shuanghu." He said. Shuanghu County, located in Qiangtang National Nature Reserve, is the county with the highest altitude in China. The oxygen content in the air here is only 40% of that in plain areas, and the number of strong winds above grade 8 is more than 200 days a year As a caretaker, losangida and seven other teammates are the watchers of this no man's land. Every morning, losangrida and his friends rode motorcycles to the depths of the no man's land. A notebook, a pen, a bag of Zanba and beef jerky, and a pair of binoculars are their common equipment. "We usually travel more than 100 kilometers at most. Sometimes we see wild animals trapped by barbed wire and rescue them," he said "Our job is usually to patrol and record." "Every time we patrol, we will classify and record the number, population and gender of Tibetan antelope, Tibetan gazelle, wolf, brown bear and other wild animals encountered along the way, so as to better monitor the changes in the number of wild animals," losangrida said Walking into yaamu management station, the reporter was impressed by all kinds of popular science pictures of wild animals and various protection slogans on the wall. "We usually go to herdsmen's homes to distribute popular science materials to let herdsmen understand the significance of protecting wild animals." Deputy stationmaster daga said. In July 2015, Tibet began the pilot reform of the management system and mechanism of Qiangtang National Nature Reserve. It is understood that at present, there are 73 management stations and 780 caretakers in the nature reserve. "We are the watchers of this land. We like to watch these 'elves' running freely on this land that belongs to them from a distance." Daga told reporters that in recent years, it has been obvious that the ecological environment of the reserve is improving, and the number of wild animals such as Tibetan antelope and Tibetan wild donkey is gradually increasing. "I have seen snow leopard many times in recent years, which was unimaginable when I was young". "They are the masters of this land" In the 1970s, with the rapid growth of population and livestock in the south of Qiangtang, herdsmen moved to the no man's land in the hinterland of Qiangtang. However, with the strengthening of ecological and environmental protection, the restorative growth of the number of wild animals has made it difficult for the local people, "how to resolve the contradiction between future generations, grasslands and wild animals?" Data show that since 1990, 87% of families in Qiangtang plateau have experienced conflicts between people and wildlife, including the "challenge" of wild animals such as snow leopard and brown bear to human daily life, as well as the increasingly prominent contradiction between grass and livestock. In order to solve the problem of harmonious coexistence between man and nature, let some herdsmen live a more comfortable life in low altitude places and make "homes" for wild animals, Tibet began to implement the high altitude ecological relocation project in June 2018. "They are the masters of this land. Return the alpine grassland in northern Tibet to them so that they can survive better." Renzeng, a herdsman, said that his family moved from Rongma Township, NIMA County, Naqu city to Gurong Town, duilong Deqing District, Lhasa City in 2018. People retreat and advance. The natural resource protection system with nature reserves as the main body has gradually taken shape, and more than 80% of the rare and endangered wild animal and plant species and typical ecosystems in the region have been effectively protected. The wildlife in Qiangtang National Nature Reserve has also ushered in a broader space for activities. In addition, in order to better solve the conflict between people and wildlife, all parts of Tibet have successively carried out commercial insurance business of wildlife accident compensation. Up to now, 722 million yuan of compensation funds have been cashed, realizing the dual objectives of safeguarding the interests of the masses and wildlife protection. "Protect our common home" In recent years, the population of some rare wild animals endemic to the plateau in Tibet has recovered significantly. So far, the number of Tibetan antelopes has increased from 50000 to about 300000, the number of black necked cranes has increased from less than 3000 to more than 8000, and the number of wild yaks, brown bears, wolves, sand foxes and other wild animals has also increased significantly. Tibet has invested more than 12.1 billion yuan to fully implement the protection and construction of ecological security barriers. Qiangtang National Nature Reserve is the largest nature reserve in China at present. It is also a dense distribution area of large rare and endangered plateau wild animals in China. It inhabits 10 species of national first-class protected wild animals such as Tibetan antelope, wild yak, Tibetan wild donkey, snow leopard, black necked Crane and 21 species of national second-class protected wild animals. It is known as the "Alpine biological germplasm resource bank". Nowadays, when tourists pass by the edge of Qiangtang National Nature Reserve in Tibet, they are overjoyed by the wonderful encounters with Tibetan antelope and Tibetan wild donkey from time to time. Such a scene is what Qiong Nu, deputy head of zabu management station of Xianqian Township in Ali area, has been looking forward to. He said: "this is our common home. We should learn and practice how to better protect wild animals. This is also the most precious treasure we leave to future generations." (Xinhua News Agency)
