摘要
随着水资源的日益紧缺,非常规水资源开发和利用越来越受到各国的重视。非常规水资源主要包括微咸水、再生水、雨水和海水等,如果合理利用,可有效缓解水资源短缺矛盾。在分析我国水资源紧缺状况与农业节水发展趋势的基础上,介绍了我国非常规水资源农业利用的必要性与可行性,总结了非常规水资源农业利用的主要方式,探讨了非常规水资源农业利用对生态环境可能产生的影响,提出了促进非常规水资源农业利用的策略建议。
Along with the increasingly shortage of water resources, development and utilization of unconventional water resources attract more and more attention from all over the world. Uncon- ventional water resources, mainly including brackish water, reclaimed wastewater, rainwater, seawater, are possible for alleviating water shortage problem if they are properly utilized. In this paper, the necessity and feasibility of unconventional water resources utilization in agriculture are presented and the irrigation technologies of utilizing unconventional water resources are summarized. On this basis, the effects of unconventional water resources utilization on regional environment are discussed, and some strategies for improving unconventional water resources utilization in agriculture are suggested.
