Xinhua Hohhot, February 20 (Reporter Li Yunping)Sand sea green, desert oasis.After years of comprehensive control, as in north China area is the largest and most comprehensive ecological function areas, Inner Mongolia autonomous region ecological conditions to realize “the overall deterioration contained, local improvement” historic transformation, gradually formed a against the sand, conserving soil and water, USES to promote animal husbandry “the great green wall”, let the important ecological security barrier in north China more solid and glorious.Kubuqi means “string on bow” in Mongolian.Kubuqi Desert, with a total area of 27.9 million mu, stretches across the northwest of Ordos city on the south bank of the Yellow River like a bowstring. This seventh largest desert in China, known as the “life exclusion zone”, was once one of the sources of dust weather in Beijing and Tianjin.In the depths of the Kubuqi Desert, in a place called “Day Sand”, a ruler of more than 10 meters high stands on the sand dune, hanging on the ruler every one or two meters of a year, each sign reflects the height of the dune, the highest point is 2009, 2012, 2014, 2016…Zhang Jishu, a sand control expert from Yili Group, told reporters that they used wind direction data to greatly reduce the height of dunes.The technique uses peak-clipping and valley filling to determine the prevailing wind direction of a moving dune. Trees are then planted below three-quarters of the height of the windward slope. The unforested top of the slope is gradually flattened by high winds, leaving a fixed spot for planting trees.”In the past 10 years, we have used this technology to control 1.6 million mu of sand, reducing the height of sand dunes in the Kubuqi Desert control area by about one third on average.”Zhang Jishu said.According to introducing, in accordance with the local “easy first then difficult, pair, overlock cutting, partition management, the whole advancement” the management idea, insisted that biological measures combined with engineering measures, focus on prevention and control combined with regional control, research and development using the windward side of container seedling planting, afforestation, water planting method, licorice planting in translation, by aerial drones and sand “black” science and technology,Scientific and effective efforts will be made to control the Kubuqi Desert.At present, 8.733 million mu of kubuqi Desert has been rehabilitated, vegetation coverage has increased from less than 3 percent in the 1980s to 53 percent, precipitation has significantly increased, sand and dust weather has significantly decreased, and the overall trend is good.Kubuqi Desert Ecological Reserve, Inner Mongolia.Hao Ying, director of the Forestry and grassland Bureau of the Inner Mongolia Autonomous Region, said that the kubuqi Desert governance is an epitome of Inner Mongolia’s overall ecological restoration and governance achievements.During the 13th Five-Year Plan period, nearly 72 million mu of desertification land has been brought under control in Inner Mongolia, accounting for more than 40% of China’s total area of desertification control, which is equivalent to three times the land area of Beijing. The transformation from “sand advancing and people retreating” to “green advancing and sand retreating” has been realized.The Inner Mongolia autonomous region is extremely important ecological status, but the ecological environment is very fragile, domestic distribution of the badain jaran, tengger, ulan buh, KuBuQi four and maowusu desert, HunShanDaKe, khorchin, hulun buir sand, four is the focus, desertification and desertification of land in our country, one of most serious harm.The ecological conditions of Inner Mongolia not only affect the survival and development of all ethnic groups in the region, but also affect the ecological security of North China, northeast China, northwest China and even the whole country.Inner Mongolia Mu us Sandy Land ecological management project area.Xinhua News Agency reporter yun-ping li was taken according to the Inner Mongolia autonomous region bureau of trees and sand Zhang Genxi xiao xun, head of the desertification land in Inner Mongolia science and promote comprehensive management, the implementation of the Beijing and tianjin sandstorm source control, the “three north” shelterbelt system construction, returning farmland to forest, natural forest resources protection and so on many national key ecological construction projects, integrate and artificial restoration of natural recovery,Comprehensive measures such as artificial afforestation and grass planting, aerial seeding and afforestation and grass planting, sand sealing and afforestation (grass) have been taken to effectively protect and restore the ecosystem in sandy areas.Zhang genxi said that Inner Mongolia has planned to build a number of different types of desertification control demonstration bases, leading to breakthroughs in desertification control work.For example, Wengniute Banner of Chifeng city focuses on controlling areas with serious land desertification hazards, forming a comprehensive sand control base of one million mu.Duolun County, Xilingol League concentrated people, money, material, built into a million mu of Pinus sylvestris base;Alxa League uses industry to build millions of acres of shuttle forest base.Wengniute Banner, Chifeng City, Inner Mongolia, carries out air seeding for sand control and afforestation.Inner Mongolia has closely combined desertification prevention and control with the development of local economy and the increase of income of farmers and herdsmen, explored various types of industrial prevention and control models, focusing on cultivating and developing the cultivation and utilization of sand plants, the cultivation and processing of special medicinal plants, desert landscape tourism and other industries.A new approach of “administrative promotion, policy promotion, industry promotion and typical driving” has been developed to combat desertification.At present, the forest coverage rate in Inner Mongolia has increased to 23 percent, the comprehensive grassland vegetation coverage has recovered to 45 percent, and the area of desertification and desertified land has been continuously reduced. The ecological condition of key desertified land control areas has been significantly improved, and some areas of desert have been transformed into oases.Ecological function area of Hulun Buir Grassland in Inner Mongolia.It is reported that Inner Mongolia has put half of its territory under the ecological protection red line and plans to significantly improve the ecological and productive functions of grasslands by 2035.Editor: Mu Yu
