Correlation between altitude, longitude and latitude and flora diversity. The correlation between altitude, longitude, latitude and diversity is measured by the correlation coefficient r. When the value of r is between 0.0 and 0.2, there is a very weak correlation or no correlation. When the value of r is between 0.2 and 0.4, there is a weak correlation. The value of r is Between 0.4–0.6 indicates a moderate degree of correlation. when the r value is between 0.6–0.8, it means a strong correlation, and when r > 0.8, it indicates a powerful correlation. a The altitude of C. pilosula planting area is positively correlated with microbial community. b The latitude of C. pilosula planting area is negatively correlated with the diversity of flora. c The longitude of C. pilosula planting area is negatively correlated with the diversity of flora. d, e and f represent the distance attenuation model of altitude, latitude and longitude and microbial community diversity
