| 摘 要： | 目的]对艾比湖湿地国家级自然保护区荒漠边缘缓冲带枸杞种植前后土壤的pH、总盐、有机质、全氮及C/N进行比较分析,评价其土壤综合质量变化情况,为保护区水土保持和经济作物种植提供依据.方法]通过人工栽培和室内试验,对枸杞种植前后及周边自然对照土样理化性质及综合质量状况进行评价分析.结果]短期天气变化对土壤pH、总盐和全氮的影响不显著,但对表层土壤有机质影响较为强烈；人工开垦、种植与灌溉对土壤理化性质影响强烈,如可降低土壤pH与土壤总盐量,有利于盐渍化土壤的改良,但同时也降低了土壤有机质与土壤全氮量；4、8月试验组与对照组的综合土壤质量指数排序为8月试验组＜4月＜8月对照组.结论]新种植的枸杞林对干旱区荒漠缓冲带土壤盐渍化具有一定的改良作用,但加剧了土壤贫瘠程度,自然条件下从春季到夏季土壤质量呈增大趋势,种植枸杞在一定程度上降低了土壤质量.

| Abstract: | 【Objective】 A comparative analysis was conducted about the soil pH,organic matter,total soil N and C/N before and after planting Lycium barbarum in Arid Desert Buffer Zone of National Nature Reserve in the Ebinur Wetland and the condition of soil comprehensive quality changes was evaluated in order that the basis for protecting areas soil and water conservation and planting economic crops could be provided.【Method】 Through artificial cultivation and indoor experiments,the physical and chemical properties and comprehensive quality status of soil samples before and after planting the Lycium barbarum and the surrounding natural control samples were evaluated and analyzed.【Result】Short-term weather changes insignificantly impacted on soil pH,total salt and total nitrogen,while the influence on surface soil organic matter was stronger;Effects of Artificial cultivation,planting and irrigation on soil physical and chemical properties were strong,such as reducing the soil pH and total salt,which was helpful to the improvement of soil salinization,while reducing soil organic matter and total nitrogen at the same time;The orders about integrated soil quality index of April,August,the experimental group and contrast group were that August test group
