以新疆艾比湖湿地泥炭土壤为研究对象,结合分析化学的手段,对泥炭土壤中的有机质、碱解氮、速效钾、有效磷等养分含量、空间分布特征进行测定与统计分析。结果表明:土壤有机质、碱解氮含量呈现出较强的表聚性,养分含量中有机质含量较高;其它养分含量较低;泥炭土壤中表层土壤有机质与碱解氮、速效钾、有效磷存在显著相关性,泥炭深层土壤的有机质与碱解氮、有效磷相关性较强;空间变异特征显示,土壤各养分指标均表现为中等空间变异特征。
Taking the peat soil in the wetland of Aibi Lake in Xinjiang as the research object and combining with analytical chemistry, the nutrient contents and spatial distribution characteristics of organic matter, alkaline hydrolysis nitrogen, available potassium and available phosphorus in peat soil were determined and statistically analyzed. The results showed that the content of soil organic matter and alkali-hydrolyzable nitrogen showed strong surface aggregation, the content of organic matter was higher in nutrient content and lower in other nutrients. The contents of soil organic matter and available nitrogen, available potassium and available phosphorus in peat soil Significantly, soil organic matter in peat soil had a strong correlation with available nitrogen and available phosphorus. Spatial variability showed that soil nutrients showed medium spatial variability.
