Abstract

based on the field survey in the past four years, the floristic characteristics of urban and rural monocotyledonous weeds in southern Junggar Basin were studied. The results showed that there were 108 species, 2 subspecies and 1 variety of monocotyledonous weeds in the study area, belonging to 52 genera and 11 families, including a new record species of exotic weeds in Xinjiang.
