Investigation find that Ageratina adenophora exist all surveyed community. In side of the road and area of human activity frequently and soil of good condition and space of rather shade, Ageratina adenophora population is more. Altitude and gradient and sloping direction and moisture etc. natu- ral factor has significantly effect on average height and individual number and sum of Ageratina adenophora population.
