The computer programme WinTWINS (Version 23), designed by Hill and Šmilauer (2005), was used to classify
vegetation types, and CANOCO (Version 45), designed by Ter Braak and Šmilauer (2002), was used for ordination
analysis. The ordination diagrams and the response curve of diversity indices to GWD and SAL modelled by the
generalised additive model (GAM) were made with the computer programme CanoDraw (Version40), designed
by Smilauer. The default cut levels (0, 2, 5, 10 and 20) were used in TWINSPAN, and the default options were
also used in the division procedure. The data on groundwater attributes (annual average value) were square
root transformed in the analysis. The significance of the resulting ordination was evaluated by 499 Monte Carlo
permutations
