Abstract
With the increasing shortage of water resources, the development and utilization of unconventional water resources have received more and more attention from various countries. Using unconventional water resources to irrigate is one of the important measures to deal with the shortage of water resources. Unconventional water resources mainly include the reclaimed water and brackish water. In China, the agricultural unconventional water resources have relatively high potentials. It has been predicted that the amount of unconventional water available for agriculture will reach 3.438×1010 m3 in 2030 and the irrigation amount of reclaimed water and brackish water will be 1.645×1010 m3 and 2.48×109 m3, respectively. In areas where the fresh water resources are lacking and the unconventional water resources are relatively abundant, especially in the arid area in the north, developing and using unconventional water resources can be regarded as a good solution for the shortage of fresh water. In this paper, based on the situation of China, the irrigation mode of unconventional water resources was summarized. From the aspects of zoning technology, suitable crop classification, pollution identification technology, high-efficient irrigation technique, monitoring and evaluation technology, and integrated application mode, this paper proposes the safe irrigation measures of unconventional water resources in China. Finally, in order to establish a technical system of agricultural unconventional water resources utilization suitable for China, this paper puts forward the development and utilization strategy, which is to further strengthen the technical research and popularization of the agricultural unconventional water resource utilization technology, to improve the recycling standards and regulation system, to bring the unconventional water resources into the planning of water resources development and utilization, and to formulate incentive policies.
