红碱淖流域湿地土壤全氮含量及分布特征研究

摘要

By the designated measurement and regional soil survey, the samples taken from Hongjiannao watershed were determined. And by integrating the soil TN, the study revealed Hongjiannao watershed wetland' s soil ecological characteristics and wetland' s succession law, and analyzed the basin of wetland soil vertical differentiation, level differentiation, seasonal change and their relationship. It laid the foundation for further research of wetland soil degradation of nitrogen, and the response of the mechanism.%通过定点测定及湿地土壤的区域调查,对取自红碱淖流域湿地土壤样品全氮(TN)含量进行测定,并整合土壤含水量、植被类型等参数,揭示了红碱淖流域湿地土壤生态特征及湿地演替规律,分析了流域内湿地土壤的垂直分异、水平分异等相关关系,为进一步研究湿地土壤退化中氮素的响应机制奠定了基础.
