Fig. 1: Research ideas and methodological design.

a Research ideas (shows the grassland NDVI and tourist sightseeing trends over the years; where t is time, SOS is the Start of the Growing Season, EOS is the End of the Growing Season, LGS is the Length of the Growing Season, and Lag is the difference between the date of NDVI peak and the date of sightseeing peak). LGS_1, LGS_2, LGS_n” now denote the Length of the Growing Season in different years, illustrating interannual comparisons of grassland phenology, while “Lag_1, Lag_2, …, Lag_n” represent the time lag (in days) between the NDVI peak and the tourism peak in corresponding years; b methodological design.
