Floristic composition, morphological functional types and habitat distributions for C4species were studied in Xinjiang, North-western China. 89 species, in 9 families and 41 genera, were identified with C4photosynthesis. 48 % of these C4species were found inMonocotyledoneae, e.g. Cyperaceae(5 species),Gramineae(38 species), the other 52 % was inDicotyledoneae, e.g. Chenopodiaceae(29 species),Amaranthaceae(7 species), andPolygonaceae(5 species). Compared with those in semi-arid grasslands in North China and tropical forests in South China, more plant families were found with the occurrence of C4plants in this arid region. Relatively higher annual species (63 %), shrubs (18 %), andChenopodiaceaeC4species (33 %) compositions were the primary characteristics for the C4species occurring in Xinjiang, and this was remarkably related with its arid environment. MoreChenopodiaceaeC4species occurring in the region suggested that this type of C4species may have higher capacity to fit the air and soil droughts. There was a strong relationship between C4occurrence and habitat distributions, more than half of the total 89 C4species were found in disturbed and cultivated lands and early stages of vegetation successions, indicating C4occurrence was not only related with climate changes, but also with land uses and vegetation dynamics.
