Xu Xinwen intake tower in the desert park. photo52-year-old Huang Ziyou and his wife live in the world's second largest mobile desert - the Taklimakan Desert hinterland a less than 10 square meters of small board room, bedside is the stove Their home is called. "021 wells room."For seven years, this couple from Sichuan, 12 hours a day in the roar of diesel generators, and guarded bite pumping wells and pumps connected to a section of thin black tube. These stretching several kilometers thin tube drip desert road on both sides of shelterbelts .After breakfast, Huangzi You walk to check whether the water within four kilometers of the scope of his jurisdiction under shelterbelts in normal drip. Desert no TV signal, no network, Huangzi completed the day's work after only entertainment is watching DVDs. In his lonely time in Haloxylon, Calligonum, tamarisk and other plants grow well.Next to the Tarim Desert Highway, like a well house, well out of every four kilometers of groundwater nourishing it stretches 436 kilometers of shelterbelts to protect the safe and smooth flow of the world in the construction of the longest desert highway.Taklimakan Desert Research Station of Chinese Academy of Sciences Xu Xinwen introduced nine years ago since the Tarim Desert Highway shelterbelt ecological project is completed, this "green corridor" effectively reduce wind speed 50-77%, sand inner belt unit time per unit width through the It was only quicksand of 0.98 to 12.55 percent."Tarim Desert Highway shelterbelt ecological engineering to eradicate the quicksand of road hazards.
to ensure the safe and smooth road, the ecological environment along the roads improved significantly, increasing the number of plant and animal species, so that once the flow of barren desert full of life. "Has been the desert for 20 years, with both feet measured each kilometer of highway through the desert Xu Xinwen said.Central Tarim Basin Taklimakan Desert 337,600 square kilometers, rich underground oil and gas resources, is China's important strategic resource base, but transportation is very difficult desert areas. In 1995, Chinese oil investment 800 million yuan to build a north-south across the Taklimakan Desert , a total length of 522 kilometers of the world's longest desert highway rating. This road becomes hub of the Taklimakan Desert oil and gas exploration and development in the southern region of Xinjiang. However, this runs through the "sea of death" after the completion of economic channels because of the continuous accumulation of sand facing severe challenges, highway maintenance costs increased year by year, has seriously hampered the normal oil and gas exploration and development.To completely cure this desert sand along the road hazards and improve the ecological environment in arid climate scientists, sand strong, high temperature hot, desert environment under little precipitation, it carried out biological and preventive measures as the main highway into the desert ecological engineering shelterbelt Research and difficult exploration.China built a total length of 436 kilometers of the Tarim Desert Highway shelterbelt ecological engineering in 2003-2006,air max femme, with a total investment of 218 million yuan. The overall belt width 72-78 meters, with a total area of 3128 hectares, planted saplings of nearly 20 million."This shelterbelt project effectively control the hazards of sand on the road.
completely changed the road along the barren landscape. It is the world's first, is a major challenge to human nature, to provide for human governance and improving the desert environment desert the success stories and scientific basis. "Xu Xinwen said.To desert oilfield bases biological protection system and Desert highway Ecological Construction screening fine species, and provides an ex-situ conservation and biodiversity research base for desert plants, China is also building a tower Desert Botanical Garden in 2002, became the world the first one in the vast sea of sand in the hinterland of the Botanical Gardens, the Botanical Garden is one of the worst natural environments in the world. Scientists have introduced more than 400 kinds of plants from the southern, northern, and Ningxia, Gansu, Qinghai, and even Africa and other places, more than 200 kinds of desert plants preserved in the tower Desert Botanical Garden.
