According to law of community succession, using perennial herbs and shrubs that later successional species displace ragweeds is an ecological control method of weeds.

Ragweeds reduced the individual number and community diversity of soil insects. According to the results of monthly ANOVA and LSD, in August and September the individual number and diversity indices of soil insects in the control plot without ragweeds were significantly higher than those in ragweed plots.

豚草降低了土壤昆虫的个体数量和群落多样性，根据逐月方差分析和多重比较，8月和9月对照样地土壤昆虫个体数量和多样性指数均显著高于豚草样地。
