| Abstract: | The relationship between growth of bulrush and 8 soil factors were studied by grey connected analysis in the ZhaLong National Wetlands. The primary and secondary factors have been educible. The results showed that the height of bulrush was mainly determined by density and organic matter, the diameter at breast height of bulrush was mainly determined by pH and available N ,and the amount of bulrush was mainly determined by available N and organic matter. The suitable of soil factors were discovered. |
