[Comprehensive assessment on control measures of Ambrosia artemisiifolia L].

Three control measures of Ambrosia artemisiifolia, including biological control, chemical control, and CK without any treatment, were evaluated by analytic hierarchy process (AHP). Corresponding contributions of the three control measures to comprehensive profit (CP) and comprehensive cost (CC) were calculated and ranked, which were regarded as the assessment criteria of the control measures. The results showed that among the three control measures, biological control had the highest CP and the lowest CC, CK was in adverse; and chemical control was in intervenient. Biological control had the highest ratio of profit to cost, and suggesting that this control measure is an optimal and recommendable measure in controlling A. artemisiifolia.
