摘　　要：针对灌溉水质、土壤安全、经济作物及荒漠植物安全等各项目标,结合灌溉制度、灌水方法、灌溉方式及土壤改良措施等动态因子,就微咸水资源化利用的安全性评价及其指标体系的建立进行了研究,确定了动态安全评价指标体系、评价方法及评价等级并编制了用于微咸水灌溉动态安全性评价的SASI软件。利用该软件对准噶尔盆地南缘莫索湾灌区微咸水农业灌溉的安全性进行了评价。评价结果表明该研究区域内,随着微咸水灌溉年份的增加,棉田土壤及作物虽然仍保持在未受污染的范围内,但污染指数逐渐增大,由此提出改善微咸水灌溉安全状况的措施及建议。This paper aims at investigating the security of irrigation water,soil,economic crops and eremophytes,together with a number of dynamic factors including irrigation scheduling,irrigation methods,irrigation water management strategies and soil amelioration methods are taken into account at the same time,then index system and method of security appraisal by using saline water are studied.Based on the dynamic security index system,judgment method and grade standards security appraisal software model named SASI are compiled.SASI software is used to appraise the security of using mildly saline groundwater for agricultural irrigation in the southern part of Junggar Basin.The result shows that as the continuous irrigation with mildly saline groundwater for years,soil and crop in the cotton field are gradually polluted to a certain degree.And finally,measures and suggestions for improving the security situation of mildly saline groundwater irrigation are put forward.
