中文摘要	针对南疆绿洲灌区224团果树滴灌条件下次生盐渍化的问题，通过在项目区布设观测井，逐月不间断的对地下水的埋深、水位及矿化度进行监测，开展对其变化规律的研究。年度观测结果显示，地下水埋深及水位在果树生育期的灌前及灌后相对较低，灌溉期内最大涨幅接近1m；地下水矿化度灌前、灌后最小，灌溉期内在2~5.8g/L范围内变动，矿化度最高值出现在果树春灌之后。研究初步表明：无排水系统滴灌条件下，滴灌对地下水水位具有一定的抬升作用，对地下水位较高区域的果树生长存在潜在威胁；同时，滴灌洗盐作用明显，土壤盐分会随地下水的流动，不断向下游转移积聚。
英文摘要	Aimed at the secondary salinization under the condition of drip irrigation on fruiter in Oasis Irrigation Region of South Xinjiang, the groundwater depth, level and mineralization were observed in succession every month in 2010by monitoring wells.The observed data showed that the groundwater depth, level and mineralization were higher in the growth period irrigation than before or after the irrigation.The most variation of groundwater depth and level was closed to 1m, the groundwater mineralization was changed from 2g/L to 5.8g/L, its highest value appeared after spring irrigation.The results showed that drip irrigation can arise the groundwater level.So drip irrigation without drainage system will be a latent threaten to fruiter growth when the groundwater level is higher.At the same time, the role of drip irrigation washing salt is obvious.The soil salt can be moved and accumulated with the flowage of groundwater to downstream.
