摘要
The climate of the loess‐hill area near Lanzhou, on the Yellow River, Gansu‐Province, NW‐China is arid throughout the year. The vegetation is xerophilic and mainly dominated by species of Zygophyllaceae, Chenopodiaceae, Plumbaginaceae, Tamaricaceae, Asclepiadaceae and Asteraceae. Among 11 species sampled of these families, δ13C‐analyses only indicated C4‐photosynthesis for 2 species. This relatively low frequency of C4‐plants may be due to elevation (1978 m a.s.l.) and the relatively cold temperatures (annual mean 5.9°C). 1990 Deutsche Botanische Gesellschaft/German Botanical Society
