中文摘要	通过三年咸水灌溉田间试验，探讨了新疆干旱区膜下滴灌条件下，咸水灌溉后土壤中盐分的分布及积累特征。研究结果表明：膜下滴灌棉田持续利用咸水进行灌溉，土壤中盐分逐年增加，积盐程度随灌溉水盐度的增加而加重。地表滴灌土壤盐分的表聚明显；而地下滴灌在滴灌管上部土层盐分含量较高。与地表滴灌相比，地下滴灌的盐分会被淋洗到更深的土层。两种滴灌方式下，0～100cm土壤平均盐度均逐年增加，且积累程度随灌溉水盐度增加而加重。在干旱区连续进行咸水灌溉，盐分的累积效应非常明显，如果不采取必要的洗盐措施，土壤中盐分最终会累积到危害作物生长的程度。
英文摘要	Saline water irrigation effects were studied in a field experiment for three growing seasons with the aim of clarifying the characters of salt distribution and accumulation under surface drip irrigation and subsurface drip irrigation in arid region of Xinjiang. Soil salinity increased with increasing irrigation water salinity levels in under-film drip irrigation. Soil salt was built up in 0-10 cm of topsoil in the surface drip irrigation treatment and accumulated significantly above the drip lateral layer in the subsurface drip irrigation treatment. Soil salt was leached to deeper layer in the subsurface drip irrigation than that in the surface drip irrigation treatment. The average soil salinity in 0-100 cm soil depth profile was increased with increasing irrigation water salinity levels in both surface and subsurface drip irrigation treatments. Those results suggested that salt accumulation increased significantly with saline water irrigation applied in the arid region.
