| 中文摘要: |
| 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。 |
| 英文摘要: |
| Peat soil in Xinjiang Ebinur Lake wetland was collected and examined through chemical analysis. The contents and spatial distribution characteristics of organic matter, nitrogen, potassium, and phosphorus were determined statistically. The results showed that the level of soil organic matter and nitrogen content in peat soil displayed a characteristic of top-down vertical differentiation, but the overall level was low. Additionally, the correlation analysis showed that there was significant correlation among the amounts of peat soil organic matter, nitrogen, potassium, and phosphorus in different surface soil layers, and there was also significant correlation among the amounts of peat soil organic matter, nitrogen, and phosphorus in different deep soil layers. Moreover, soil nutrient spatial variations seemed to be at moderate level. In conclusion, the study in this area provided scientific fundamentals for rational protection of peat resources usage, to stabilize and restore ecological environment. |
