摘  要：
[目的]对新疆地区进行土壤盐分特征分析,开展该区土壤盐渍化特征研究,为干旱地区盐渍化研究提供参考依据。[方法]以克拉玛依碳汇林中不同土地类型的土壤垂直剖面为研究对象,对其土壤盐分、可溶性离子进行测定,运用统计特征值、趋势面等方法进行分析,探讨该区域土壤盐分分布特征。[结果]碳汇林研究区土壤中盐类主要为硫酸盐-氯化物型及氯化物型,其中阳离子主要是Na+、K+和Ca2+,阴离子主要有CO32-,Cl-和SO42-;CO32-变异系数高达292.91,Cl-的变异系数为265.56。土壤可溶性总盐在0～100 cm土层中变化趋势不显著,土层中的含量较稳定。[结论]该研究为加快对土壤盐渍化的动态监测,寻找盐渍化有效地控制途径奠定基础。

摘  要：
[Objective] The paper was to analyze the soil salinity characteristics in Xinjiang region,and develop salinization characteristic research,so as to provide reference for salinization research in arid region.[Method] With different land types of soil vertical profiles in Karamay absorbing carbon forest as research object,soil salinity and water soluble ions were determined and analyzed using statistical characteristic value and trend surface,and the distribution characteristic of soil salinity in the region was explored.[Result] The salinity in survey area of absorbing carbon forest mainly were sulfate-chloride type and chloride type,of which cations were mainly Na+,K+ and Ca2+,anions were CO32-,Cl-and SO42-,the variation coefficient of CO32-was as high as 292.91,while the variation coefficient of Cl-was 265.56.The variation of soil total soluble salts in the soil layer of 0-100 cm was not significant,indicating that the content in each soil layer was relatively stable.[Conclusion] The study provided basis for speeding up dynamic monitoring for soil salinization and finding the effective control approach against salinization.
