In this paper, we sampling surveyed on the Reaumurta soongorica populations naturally distributed in semi-desert vegetated area of Yongdeng, Lanzhou. Through analysised the relationship between R. soongorica stem basal diameter and age, the regression equation was established to get the age of the corresponding basal diameter. We made the static life table, analyzed the dynamics index, the survival curves and survival analysis curves. The results showed that: the R.soongorica populations in different habitats had lots of seedlings, the seedlings accounted for large proportion of the populations. The population survival curves in all plots were close to Deevey-Ⅲ type (concave). The static life tables showed the R. soongorica populations adopted two kinds of different strategy for the habitat heterogeneity, especially different water conditions. The population dynamics index Vn were positive value, fully illustrated the R. soongorica populations were in the developing state, and the overall populations kept on the tendency with steady increasing.
