  1. The reproductive characteristics and population structure of artemisia ordosica, hedysantm scoparium, caragana korshinskii and the reproductive characteristics of annual plants eragrostis poaeoides and bassia dasyphylla were observed in shapotou artificial revegetation area. stability of the artificial vegetation was appraised from the views of its persistence and variability under local natural condition. the study showed that : the artificial - natural vegetation built with sandbreaks and plants is stable in shapotou area
