摘  要:
为了给艾比湖地区防风治沙及生态恢复工作提供科学依据,以艾比湖主要供给河流——博尔塔拉河下游河岸带土壤为研究对象,对不同植被类型覆盖条件下土壤总盐含量、可溶性离子等指标进行定量测定,并进行相关性分析以及主成分分析。结果显示:研究区土壤盐含量表聚性较强;土壤中的总盐含量与HCO3-,K++Na+存在极显著的正相关关系;HCO3-,Cl-,K++Na+是研究区盐渍化状况的特征因子。研究区土壤次生盐渍化严重,经盐渍化分级为盐土。

摘  要:
In order to provide a scientific basis to prevent dust and ecological restoration,as the research object of Bohe River riparian,the total salt content,contents of eight ions under the conditions in different types of vegetation were quantitative measured.According to the correlation analysis and principal component analysis,the results show that salt accumulation in surface is significant;the total salt content in the soil is significant positive correlation with the HCO-3,K+,Na+;HCO-3,Cl-,K+ and Na+ are the characteristic factors of salinization;conclusion is that secondary soil salinization is serious in the study area.Soil is classified saline soil according to salinization classification standard in the study area.
