Correlative Analysis of Two Water Chemistry Parameters Affecting the Distribution of Ceratopteris thalictroides in China
[Objective] The relationship of two water chemiscal parameters affecting the Ceratopteris thalictroides was analyzed to provide the basis of its protection and population restoration. [Method] The coefficient of variation of the average values of 22 water chemiscal parameters from 22 sampling places distributed in China's tropical and subtropical region was calculated and the multiple comparative analysis and correlation analysis between two chemical factors with significant difference were done with the Method of least significant difference and the correlation coefficient, respectively. [Results] There was large variation in change coefficient of 22 chemical factors measured, but only the difference of pH value and electrical conductivity in two water bodies (type A and type B) was significant, which was a positive correlation. And the multiple comparison analysis showed that the significant difference of pH value between water bodies was higher than that of electrical conductivity. [Conclusion] In the two chemical factors with significant difference, the impact of pH value in water body on the distribution of Ceratopteris thalictroides was greater.
