Abstract The diameter-class structure, age-class structure, time-specific-life-table and survivorship curves of P. Euphratica populations in different habitats of Tarim River were analyzed on the base of a field investigation. In order to analyze quantitatively the dynamic changes of P. euphratica populations, population dynamics quantitative analysis method was also adopted. The results showed the population structures were different in different habitats, especially there was significant difference among downstream, upper and middle reaches of Tarim River. The seedlings of P. euphratica populations were abundant at upper and middle reaches of Tarim River, and the diameter-class and age-class structures of populations presented pyramidal form with a survivorship curve of Deevey-C (concave-type) type. Moreover, the dynamic indices of populations were bigger than 0, and these populations were progressive. Compared to populations of upper and middle reaches of Tarim River, the seedlings number at downstream reaches of Tarim River is rare and the growth is bad. The diameter-class and age-class structures of populations there presented a skewed normal distribution and with a survivorship curve of convex-type. Furthermore, the dynamic indices were less than 0, which indicated the populations were degenerative type.
