[目的]探讨干旱区盐渍化严重地区芦苇与盐分关系,揭示芦苇地下生物量垂直分布规律。[方法]通过野外调查、野外实地采样得到了较准确的芦苇种群地下生物量数据,利用统计学和生态学相结合的方法分析了芦苇地下生物量的垂直分布。通过试验测定了芦苇湿地有机碳和全氮的含量,求取了C/N比值,并分析了三者之间的相关性模型。[结果]芦苇种群地下总的生物量集中在10～40cm土层,粗根在总的生物量中起明显的决定性作用。有机碳和全氮总体变化呈下降趋势,50cm以下土壤有机碳和全氮变化趋势稳定。土壤有机碳与全氮含量呈显著正相关。[结论]为干旱区盐渍化地区芦苇地下生物量的获取提供了理论依据。

[Objective]The aim of this study was to reveal the relationship between the reed and salinity in severely salinized area,so as to making clear the vertical distribution of underground biomass of reed.[Method]Field investigation and sampling method were used to get the mass accurate data of underground biomass of reed.further its vertical distribution was analyzed using combined statistical and ecological method.Moreover,the C/N ratio was obtained by measuring the contents of organic carbon and nitrogen in reed wetland soil.The correlation model among organic carbon,nitrogen of reed wetlands and C/N were finally analyzed.[Result]Total underground biomass of reed population is concentrated at 10 to 40 cm underground soil layer.Thick root plays crucial role in the composition of reed total biomass,Overall change of organic carbon and total nitrogen shows a declining trend.The content of organic carbon and nitrogen in soils becpmes stable below 50 cm from the surface.The content of organic carbon in soil is positively correlated with total nitrogen in soil at significant level.[Conclusion]These results provided theoretical basis for revealing underground biomass of reed in salinized area of arid region.
