Abstract: Using mark-recapture method and according to the snout-vent length growth pattern,five age groups of Phry,iocephalus przewalskii on deserts are differentiatecd.And based on the data of lizards morpholo-gy,the community of Phrynocephalus przewalskii with 30-81mm snout-vent length is differentiated in-to five body length groups by fuzzy cltster analysis method,which are basically in accordance with corre-sponding age groups,These biological and mathematlcal methods are both proved to be feasible in age dif-ferentiation of Phrynocephalus przewalskii.
