Lanzhou, September 4 (Cui Lin, Gao Zhan, Huang Wanyi) Since the beginning of autumn, the Water Flowing Water in the Reservoir Area of the Red Cliff Mountain Reservoir, which blocked the two major desert "meetings" of Tengger and Badain Jarin, has been babbling, and the surrounding machine wells have flowed into springs, nourishing nearly 300,000 people in Shaxiang. Over the years, in addition to becoming a place for migratory birds to fly, the ecological zone has attracted more and more tourists to come to enjoy the scenery.

Located in the northeast of the Hexi Corridor, downstream of the Shiyang River, about 30 kilometers from the county seat of Minqin, Hongyashan Reservoir is a desert depression water storage project and the largest desert reservoir in Asia.
Gao Peixing, director of the Wuwei Minqin County Water Bureau, said that since 2010, the Hongyashan Reservoir has accumulated 280 million square meters of ecological water discharged into Qingtu Lake, the water area of Qingtu Lake is 26.7 square kilometers, and the northern lake area has formed about 106 square kilometers of arid wetlands.
Gao Liwen, former secretary of the party branch of Liugou Village in Daba Town, has been working in this post for 27 years. He told reporters that before the comprehensive management of the Shiyang River Basin was carried out in 2015, affected by the sand, there were countless villages buried in quicksand, the water for production and living was limited, and the people took a bath at most once a year, without any income, and it was not too much to be called an ecological refugee.
In order to alleviate these dilemmas, the reservoir was built in 1958 to integrate water storage irrigation, flood control and control functions, while playing an important role in injecting ecological water into the downstream Qingtu Lake to block the confluence of the two deserts. The water from the reservoir is mainly composed of three parts: the normal water from the natural river in the middle reaches, the water transfer of the second phase of the Jingdian polling project, and the water transfer of the Xiying River in Liangzhou District.
Gao Peixing said that the construction of the Hongyashan Reservoir is of great significance for supporting the survival and development of the Minqin Oasis, consolidating and expanding the key governance achievements of the Shiyang River Basin, and maintaining the ecological balance of the basin. He pointed out that at present, the forest coverage rate of the county has increased from 11.52% in 2010 to 17.91% in 2019, and the area of desertification and desertification has shown a trend of decreasing and decreasing year by year, and the overall trend of containment and reversal is in the trend of containment and reversal, and the number of sandstorms has decreased significantly.
After the ecological improvement, minqin county officials began to promote comprehensive agricultural water-saving technologies such as pipeline water transmission, sub-membrane drip irrigation, small pipe outflow, small furrow irrigation, ridge crop furrow irrigation, ridge film ditch irrigation, and mulch film reuse no-tillage, and actively adjusted and optimized the agricultural industrial structure. In the past, Liugou Village, which was difficult to bathe, now has 1452 acres of ginseng fruits, and is continuing to expand the solar greenhouse, with an average income of about 80,000 yuan in the shed, and the people of Shaxiang are at ease to buy a range Rover here.
Gao Peixing said that it is gratifying that the total water consumption of the county has decreased from 744 million square meters before the treatment to 413 million square meters now. The unilateral water efficiency of agriculture increased from 3.46 yuan in 2007 to 21.7 yuan in 2019, and the per capita disposable income of farmers increased from 4666 yuan in 2009 to 14414 yuan in 2019, achieving a win-win situation between ecological protection and farmers' income.
He also frankly said that although the key governance of the Shiyang River Basin has achieved remarkable phased results, due to the large number of historical debts, the long-term mechanism has not yet been established, the long-term accumulation of ecological risks has not been eliminated, the momentum of the two major deserts converging still exists, to ensure the ecological water use and ecological vegetation restoration of the Minqin Basin, it is necessary to rely on the external basin water transfer to solve, and fundamentally solve the problem of local oasis ecological water use.
