艾比湖湿地芦苇生长土壤的化学特性

以艾比湖湿地不同样点芦苇生长的土壤为研究对象，对土壤中盐分、可溶性离子、pH值以及速效养分指标进行测定。结果表明：芦苇适生土壤中，总盐分布呈现出较强的表聚性并且均值不大于10 g·kg^-1，总盐与HCO₃^-具有显著相关性；阳离子中K⁺+Na⁺含量最多，阴离子则为HCO₃^-含量最多；养分含量中水解氮和速效磷丰富；土壤pH值变幅在8.28～8.46之间。研究结果说明艾比湖湿地芦苇生长的土壤盐分含量高、养分含量低，以碱性土壤为主。

Chemical properties of reed growing soil in Ebinur wetlands

With the reed growing soil at different sampling sites in Ebinur wetlands as the research object, the salinity, soluble ions, pH and available nutrients were measured. The results showed that, in reed suitable soil, the distribution of total salt showed a strong surface cohesion and the mean value was no more than 10 g·kg^-1. There was a significant correlation between total salt and HCO₃^-. The content of K⁺+Na⁺ was the highest in cation, while that of HCO₃^- was the highest in anion. There were affluent hydrolysis nitrogen and available phosphorus among all nutrients, and the soil pH varied from 8.28 to 8.46. It can be concluded that the salt content is high, the nutrient content is low and the soil is alkaline in Ebinur wetlands.
