The investigation showed that there were 34 species of weeds belonging to I5 families in this region. And 22 species belonging to 7 families, which were heavily harmful, and accounting for 64. 71% of the weeds.

Xi county ranked the highest weed amounts, reaching for 284 plants/m^2, the experimental field of Academy of Agricultural Sciences was the lowest, reaching 85 plants/m^2. The abundant species of weeds was unite field which had 16 species. Cyperaceae and MoUugo pentaphylla L. with the highest A and F were regarded as the dominant populations.
