为了研究不同灌溉模式对土地整治项目区土壤环境、地下水矿化度和埋深的影响，在内蒙古河套灌区选定具有代表性的红卫试验场进行了枸杞田间微咸水灌溉试验，探讨对土壤环境、地下水环境影响最小的枸杞微咸水灌溉模式。结果表明：不同轮灌模式下土壤盐分均发生表聚现象，在枸杞根系发达区淡-咸-咸灌溉模式下土壤盐分最低，对枸杞生长影响较小；地下水矿化度存在显著差异，淡-咸-咸灌溉模式下枸杞整个生育期内地下水矿化度最低，咸-咸-咸灌溉模式下最高；不同轮灌模式下地下水埋深差异不大，并且在生育期末基本回到了开春时的水平；淡-咸-咸灌溉模式对地下水环境影响较小，是适合当地土地整治采用的最优灌溉模式。
為瞭研究不同灌溉模式對土地整治項目區土壤環境、地下水礦化度和埋深的影響，在內矇古河套灌區選定具有代錶性的紅衛試驗場進行瞭枸杞田間微鹹水灌溉試驗，探討對土壤環境、地下水環境影響最小的枸杞微鹹水灌溉模式。結果錶明：不同輪灌模式下土壤鹽分均髮生錶聚現象，在枸杞根繫髮達區淡-鹹-鹹灌溉模式下土壤鹽分最低，對枸杞生長影響較小；地下水礦化度存在顯著差異，淡-鹹-鹹灌溉模式下枸杞整箇生育期內地下水礦化度最低，鹹-鹹-鹹灌溉模式下最高；不同輪灌模式下地下水埋深差異不大，併且在生育期末基本迴到瞭開春時的水平；淡-鹹-鹹灌溉模式對地下水環境影響較小，是適閤噹地土地整治採用的最優灌溉模式。

In order to study the influence on different irrigation modes to the environment of soil, groundwater salinity and buried depth of land renovation project, this research selected representative filed which is called Hongwei testing field to carry on the experiments of brackish water irrigation in Hetao irrigation area in Inner Mongolia for wolfberry and studied the minimum influence of brackish water irrigation mode to the environment of soil and groundwater for wolfberry. Results show that soil salinity is occurred surface assembled phenomenon under the different rotational irrigation modes, soil salinity of fresh-salty-salty mode is the lowest in the wolfberry root developed area and the influence to the wolfberry grow is smaller; the groundwater salinity exists significant difference under different rotational irrigation modes, groundwater salinity is the minimum throughout the reproductive period under the fresh-salty-salty mode for wolfberry, groundwater salinity is the highest under the salty-salty-salty mode, from small to large followed by fresh-salty-salty < salty-salty-fresh <salty-fresh-salty < salty-salty-salty;ground water depth is different under the different rotational irrigation modes, at the end of period of growth, it returns to the level of the spring. Therefore, the influence of fresh-salty-salty irrigation mode to the groundwater environmental is small, it is suitable for irrigation mode adopted by the local land renovation project.
