- •
Responses of the halophyte Tamarix chinensis to temporal-spatial variability with environmental factors are focused.
- •
Variations in the season, sunlight, soil salinity, air temperature and relative humidity control the changes in δ13C.
- •
C content varies with seasonal variations in the air temperature, precipitation and relative humidity.
- •
Differences in the N content can be explained by differences in the quantity of sunlight received.
- •
The C:N ratio is mainly affected by sunlight received and significantly correlated with the N content while weakly correlated with the C content.
