[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 further research on the restoration of dominant vegetation-reed in wetlands. [Method] The correlation between total nitrogen, total phosphorus, organic matter, water and reed soil of Phragmites australis in the typical vegetation of Huixian wetland in Guilin was analyzed by field survey and indoor experiment. [Result] The coefficient of variation of C / N ratio was 0.16, the coefficient of variation of C / P ratio was 0.41 and the coefficient of variation of N / P ratio was 0.40 in the reed area of Huixian wetland. [Conclusion] The finer grain size of soil sediments in Huixian wetland, in which the contents of nitrogen, phosphorus and organic matter were also high, the more conducive to the growth and development of reed.
