摘　　要：梭梭和柽柳既是维持生态平衡的重要的荒漠植物,也是宝贵的沙生经济植物。在咸水资源丰富地区,研究了咸水滴灌条件下梭梭和柽柳生长的土壤的水平湿润区、土壤湿润体内部水分变化特点,湿润范围表层盐分和湿润体内部盐分的运移特征。一方面,为开发和利用当地丰富的咸水资源进行了尝试,另一方面,两种植物在高矿化度的水环境下生长,为咸水的安全利用及维持主要荒漠植物梭梭和柽柳成活提供了初步的参考。Haloxylon ammodendron and Tamarisk are not only important desert plants to maintain the ecological balance but also valuable desert economy plants.In an abundance of the saline water resources area,this paper studies the moisture movement law of the soil horizontal wetting area and in the wetting body,the characteristics of the soil salt movement of surface wetting areas and in the wetting body for Haloxylon ammodendron and Tamarisk under drip irrigation conditions.On the one hand,this is a practice to exploit and utilize the local saline water resources,on the other hand,it serves as a reference for the safe use of saline water and maintaining the living of the main desert plants,Haloxylon ammodendron and Tamarisk,if two plants can keep growing under such salinity groundwater conditions.
