摘　　要：本研究依托于新疆干旱区和民勤盆地红崖山灌区水资源和沙区植被调查分析,展开对地下水位回升及地表用水的节水模式科学调控,对土壤水分平衡影响进行探讨,并评价植被特征与植被恢复能力。通过重点规划治理和红崖山灌区水资源科学配置与节水调控模式,运用Origen数据软件线性拟合与Excel数据统计分析地下水开采量与地表水高效利用模式.结果表明:对土壤水分平衡研究,发现降水条件下布设麦草沙障的人工梭梭林比白刺包蒸散量小,其土壤有效储水效果更好,两者降水截留效果基本一致;对植被恢复能力试验得出,在灌区水生态治理时地下水恢复与地表水优化配置两种模式相结合,稳定实现可持续化恢复。Based on the investigation and analysis of water resources and vegetation in the Hongyashan Irrigation District of Xinjiang arid area and Minqin Basin,this study carried out scientific regulation of water-saving models for groundwater level rise and surface water use,discussed the impact of soil water balance,and evaluated vegetation characteristics and vegetation restoration capacity.Through the key planning and management and the scientific allocation of water resources and water-saving regulation and control mode of Hongyashan Irrigation District,the linear fitting of Origen data software and Excel data statistics are used to analyze the groundwater exploitation and the efficient use mode of surface water The results showed that the evapotranspiration of the artificial Haloxylon ammodendron forest with wheat straw sand barrier was smaller than that of Nitraria barbadensis,and the soil effective water storage effect was better;According to the test of vegetation restoration capacity,the combination of groundwater restoration and surface water optimal allocation can stably realize sustainable restoration.
