Research on Agricultural Water-Saving Potential for Oasis Security and Sustainable Development in Arid Areas
摘要
Abstract
In order to ensure oasis security under total water use control and achieve the sustainable development goals in arid areas,taking the Kaikong River watershed in Xinjiang as an example,a new method for calculating irrigation water-saving potential in arid areas was pro-posed based on the constraint conditions of total water use control index and groundwater safety.The results show that a)the current annual(2020)groundwater extraction in the Kaikong River watershed is 1.297 billion m3 and the total irrigation water is 3.485 billion m3.Under the traditional water-saving model,the water-saving potential of the watershed is 74 million m3 in the medium-term planning year(2030)and 502 million m3 in the long-term planning year(2050).b)Under the new connotation of water-saving potential,there is no water-saving po-tential in the Kaikong River watershed in the medium-term planning year,and 18 667 hm2 needs to be fallow,while the longvterm planning annual water-saving potential is 177 million m3.c)In order to prevent secondary salinization in arid areas and achieve sustainable develop-ment in arid areas with water shortage,the groundwater level of oasis should be controlled between 3.5 m and 4.0 m after saving water.For the irrigation area with water and soil imbalance,the importance of oasis safety is not enough under the traditional water-saving thinking,and the evaluation of water-saving potential is too high.关键词
