Ephemeral plants are an important part of desert ecosystems. To understand the stoichiometric characteristics of leaf N and P in growth season variation, we compared plant leaf N and P with seasonal variation among 6 main species of ephemeral plants in the Gurbantunggut Desert in China, including 3 species of annual ephemeral plants and 3 of perennial ephemeral plants: Erodium oxyrrhynchum, Nepeta micrantha, Alyssum linifolium, Eremurus chinensis, Scorzonera pusilla, and Soranthus meyeri. The mean N content for the 3 annual ephemeral species was (11.23±7.16), (14.11±6.38) and (10.85±6.14) mg·g-1 and mean P content was (2.82±0.73), (3.12±1.24) and (3.43±0.55) mg·g-1. The mean N content for the 3 perennial ephemeral species was (19.97±5.94), (15.08±4.01) and (17.94±9.03) mg·g-1 and mean P content was (3.55±0.83), (2.73±1.11) and (5.03±0.65) mg·g-1. The stoichiometric characteristics of leaf N-P differed during the growth of ephemeral plants. The content of N and P in each species was higher in the early growth stage than during other growing seasons. The content of N and P decreased with increasing leaf biomass in the growing season but increased in the late growth season. The relation among the elements at different life stages differed, with no significant difference in the relation between the elements of the same life stage, so it embodies the consistency of inter species.
