摘　　要：为科学管护吐鲁番盆地的人工梭梭防护林,本文对4个国家气象观测站的降水数据和32眼观测井的地下水位数据进行了分析。结果表明,吐鲁番盆地水资源极为稀缺且时空分布差异明显,绝大多数地区的地下水位过深,无法被人工梭梭林利用,且无法通过天然降水为快速生长期的人工梭梭林提供有效的土壤水分补给。因此,在该地区进行人工梭梭防护林建设时,需结合实际情况进行灌溉需求分析,避免人工梭梭林因长期缺水严重退化。To scientifically manage the artificial haloxylon ammodendron forest protective forest in Turpan Depression,this paper analyzes precipitation data from four national meteorological observation stations and groundwater level data from 32 observation wells.The results indicate that water resources in Turpan Depression are extremely scarce,with significant spatial-temporal distribution variations.In the vast majority of areas,the groundwater level is too deep to be utilized by the artificial haloxylon ammodendron forest,and natural precipitation cannot effectively provide soil moisture replenishment during the rapid growth period of the artificial haloxylon ammodendron forest.Therefore,when establishing the artificial haloxylon ammodendron forest in this region,irrigation demand analysis should be conducted in conjunction with the actual conditions to avoid severe degradation of the artificial haloxylon ammodendron forest due to prolonged water shortage.
