Species composition and important values of lithophytic moss in different elevation gradients

Supplementary Table 1 shows that a total of 58 bryophyte species belonging to 13 families and 27 genera were recorded in the karst urban survey sample, and the species composition was different in different altitude gradients, and the important values were significantly different.  Supplementary Table 2 shows that Chi-square test and Jaccard index comparison of dominant species of lithophyte moss at different elevations in urban areas. Supplementary Table 3 shows that the correlation coefficients of lithophytic moss in different altitude gradients are quite different. Supplementary Tables 4 and 5 show that the Canonical Correspondence Analysis ranking results of 117 plots and 9 environmental factors and stability can better explain the changes in species composition., The data in supplementary Table 1 are the important value information of Lithophytic moss species at different elevations in karst cities. The data is based on the ArcGIS10.2 software and fishing net grid, which divides the urban area into four elevation sections and sets survey sample sites. Each sample site is selected with a 10m×10m large square, which is then divided into five medium squares (2m×2m). Within each medium square, the 5-point sampling method is adopted.  Using 10cm×10cm metal mesh, 5 small quadrats were identified and sampled, and the coverage and frequency were recorded. All specimens were brought back to the laboratory and identified by microscope. The relative coverage and relative frequency are used to calculate the important values. Supplementary Table 2 shows the Chi-square test and Jaccard index comparison of dominant species of lithophyte moss at different elevations in urban areas. The data in supplementary Table 3 are  Semi-matrix of Pearson and Spearman rank ..., , # Species composition and important values of lithophytic moss in different elevation gradients

## Description of the data and file structure

This file consists of supplementary tables 1, 2, 3, 4, and 5. The contents of each file, the software used and the analysis results are different. The details are described as follows：

**Supplementary Table 1**：Species composition and important values of lithogenic bryophytes in different elevation gradients

Supplementary Table 1 shows that 58 bryophyte species belonging to 13 families and 27 genera were recorded in the karst urban survey sample, and the species composition was different in different altitude gradients, and the important values were significantly different.

We surveyed lithophyte moss in the downtown area of Guiyang with a sample method (Nanming District, Yunyan District, Huaxi District, Wudang District, Baiyun District, and Guanshan Lake Dist...
