中文摘要	通过对甘肃省景电灌区的水盐引排量的统计和土壤、排水沟水溶性盐组分浓度与TDS关系分析,总结了干旱扬水灌区引排水盐的特点。研究表明,干旱扬水灌区内的降水、潜水出露的径流、地下水灌溉等在灌区水盐循环中的作用与引黄灌溉量和干沟的排水量相比处于次要地位,人工的扬黄灌溉对灌区水循环的影响远远超过自然因素的影响强度,灌区内水土的水溶性盐在迁移过程中具有明显的共生聚集规律性,并与难溶盐组分的分异作用显著,这种作用主要受控于可溶性盐在水土中迁移的稳定性、迁移速率及方向。通过合理地调控地表水及其与地下水在循环过程中的量比关系,可以有效预防次生盐碱化的发生。
英文摘要	Based on statistics of water and salt input and excretion in the Jingdian irrigation area,and,through analysis relations of the components of soluble salt concentration and TDS in the soil and drain,Summarizes the characteristics of water and salt input and excretion in the arid pumping Irrigation area.Study shows that:The role of precipitation,the runoff diving exposed and groundwater irrigation in water and salt circulation of arid pumping irrigation area is not important than the volume of irrigation and drainage of the discharge,the impact of artificial irrigation on irrigation water cycle is far more than the strength of natural factors affect.During the migration process,water-soluble salt of irrigation water and soil have apparent regularity of the symbiotic,soluble salt components with a significant effect on differentiation.This effect is controlled by stability,migration rate and direction of the migration of soluble salts in the soil and water.Through reasonable control the ratio of the surface water and groundwater in the cycle can be effective in preventing the occurrence of secondary salinization.
