英文摘要	The differences in nitrogen/phosphorus (N/P) ratios of different functional groups in ecology are more helpful in explaining species competition and community dynamics. Based on the functional groups of plant growth type, carbon metabolism pathway, root type and phylogenetic type, we analyzed characteristics of leaf N/P ratios of 77 species in Sanggendalai (typical grassland zone) of Zhenglan Banner, Inner Mongolia, China and 91 species in the Habahu National Nature Reserve (desertified grassland zone) in Yanchi County of Ningxia, China. The results show that the N/P ratio (16.91) of C-3 plants in the desertified steppe was significantly larger than that (12.72) in the typical steppe, but there was no significant difference between the N/P ratios of C-4 plants in the two zones. There was no significant difference in N/P ratios between C-3 plants and C-4 plants in the same zone. Similarly, the N/P ratio (16.60) of dicotyledons in desertified steppe were significantly higher than that (12.98) in typical steppe, while differences in N/P ratios between monocotyledonous plants of the two zones was not significant, and there existed no significant difference in N/P ratios between dicotyledonous and monocotyledonous plants in the same zone. The N/P ratio had significant difference between gramineous and non-gramineous plants in the typical steppe but not in the desertified steppe, but there existed no significant difference in N/P ratios among different root types of perennial herbaceous plants in the same type of steppe or between two types of steppe. Thus, different features on the N/P ratios of C-3 plants and dicotyledonous plants between typical steppe and desertified steppe may lead to different growth status of plants, and the N/P ratio stoichiometric of the same plant functional group may be a foundation of the changes of a plant community.
