    摘要:

    大田滴灌在新疆地区大规模应用取得了非常显著的经济、社会和生态效益,但不同区域应用时,对土壤水盐平衡及地下水动态的影响也各异。为准确掌握长期节水灌溉对新疆农田土壤水盐及地下水埋深的影响,本文系统梳理了新疆大田滴灌的发展历程及取得成效,分析了长期大田滴灌以来耕层土壤水分状况、南北疆的主要灌区农田地下潜水埋深、耕层土壤盐分再分布的变化情况,并从维护新疆水土资源可持续利用角度提出4条对策与建议:“两水”统观统用构建安全地下水位埋深、灌溉洗盐结合维持良好农田耕层、区域统防统治实现区域水土可持续、节水降盐为核心提升区域农业资源利用效率,为进一步开展新疆农业水资源可持续利用提供参考和方向。节水抑盐是新疆农业可持续发展的战略举措,但如何实现干旱盐碱区水土资源的高效利用,探索和遵循水盐平衡这个科学问题值得长久关注。

    Abstract:

    The large-scale application of field drip irrigation in Xinjiang has achieved significant economic,social and ecological benefits,but its impact on the water and salt balance in soil and the dynamics of groundwater is different in different regions as well. This article systematically reviewed the history of development and achievements of field drip irrigation in Xinjiang to accurately understand the effect of long-term water-saving irrigation on water-salt balance in soil and groundwater level in Xinjiang. The changes of soil moisture in the topsoil,the depth of underground phreatic water in the farmland in the main irrigation areas in northern and southern Xinjiang,and the redistribution of soil salt in the topsoil since the long-term field drip irrigation were analyzed. Four countermeasures and suggestions are put forward from the perspective of maintaining the sustainable use of water and soil resources in Xinjiang. The groundwater and surface water are overall used to build a safe groundwater level. Scientific irrigation and drainage shall be combined to maintain good farmland topsoil. Unified planning and utilization of saline alkali land in the region is used to realize the sustainable utilization of regional water and soil resources. Water saving and salt reduction is used as the core to improve the utilization efficiency of regional agricultural resources. It will provide reference and direction for further developing sustainable utilization of agricultural water resources in Xinjiang. Water saving and salt reduction is a strategic measure for the sustainable development of agriculture in Xinjiang in the future. However,how to realize the efficient use of water and soil resources in arid saline-alkali areas and explore and follow the scientific issue of water and salt balance deserves long-term attention.
