QHNEWS -- The ecology-based construction in the Sanjiangyuan National Nature Reserve has come to its implementation phase. Being able to transmit 1.2 billion cubic meters of water to the rivers of its lower reaches with an estimated value of over 70 billion Yuan, the water resources of the Sanjiangyuan can efficiently alleviate the harsh water shortage in North China.
Having the most influential accommodating role for China¡¯s ecology, even in the world, the Sanjiangyuan is the important water resources for the upper reaches of the main rivers in both China and Asia and is also an area from which most of the great rivers on the Euro-Asian Continent originate.
As the core of the whole Sanjiangyuan Area, the Sanjiangyuan Nature Reserve is the most concentrative region with ecologial types and possesses the most important ecological status and the most integrated ecosystem in its 152,300-square-km area, 42% of the whole Sanjiangyuan Area. According to the General Program on Ecology-based Protection and Construction of the Sanjiangyuan Nature Reserve in Qinghai, which was approved and maily funded early this year by the State, 7.507 billion Yuan will be invested for the construction of the nature reserve. The program covers three sections, involving ecological-based protection and construction, infrastructure construction for farmers and herders¡¯ production and living, and sustainable work for the protection of the nature reserve.
In detail, the first section includes 8 items: the reconversion of the grasslands from pasture-purposed use, the reconversion of the grasslands from being already assarted, the reconversion of the forests from plant cultivation, the restoration of deteriorated land, the fireproofing of forests and grasslands, the control of rat threat, conservation of water and soil, and the protection of the facilities. The second section refers to the migration of the people in the nature reserve area, township construction, the auxiliary project for grassland protection , and water supply project for people and livestocks. The third section contains project of artificial rainfall, supervision of the dynamic ecology and the support of science and technology.
Upon the gradual implementation of the above program, by the 2010, 96,582,900 mu of grassland is planned to be reconverted from pasture-purposed use; 4,520,000 mu of mountain forests is planned to be cultivated through sealing mountains; 98,100 mu of forests is planned to be reconverted from plant cultivation; 661,500 mu of land is planned to restored from desertification; an increase of vegetation coverage between 20% and 40% and a 1.32-billion-cubic growth of water conservative amount is expected .Valued by the current water consumption amount of per ten thousand GDP, it is estimated that the Sanjiangyuan will bring about a production value of over 70 billion Yuan after the program as it can transmit 1.2 billion cubic meters of water to the rivers of the lower reaches. By then, the ecological environment of the Sanjiangyuan Area will be improved greatly and undoubtedly become ¡° a natural shelter for wild living creatures¡± and ¡°a gene bank of biological species¡±.
