摘　　要：[目的]为进一步恢复湿地优势植被——芦苇的研究提供科学依据。[方法]采用野外调查和室内实验相结合的方法,分析桂林会仙湿地典型植被芦苇土壤全氮、全磷、有机质、水分与芦苇之间相关性。[结果]会仙湿地芦苇区域内的C/N比变异系数为0.16,C/P比变异系数为0.41,N/P比变异系数为0.40。[结论]会仙湿地土壤沉积物粒度越细,其中氮、磷、有机质含量也高,越有利于芦苇的生长发育。[Objective] The research aimed to provide a scientific basis for the further restoration of wetlands dominant vegetation-reeds.[Method] The methods of field surveys and lab experiments were carried.The correlation was analyzed between reed and soil total nitrogen,total phosphorus,organic matter,water in Huixian wetland.[Result] The variation coefficients of C/N ratio,C/P ratio,N/P ratio in Huixian wetland area were 0.16,0.41,and 0.40.[Conclusion] Sediment particle size was finer,and the contents of nitrogen,phosphorus,organic matter content was higher,which was beneficial for the growth of reeds.
