摘要: 运用层次分析法对豚草生物防治、化学防治和不实施任何防治措施的空白对照进行综合评价.对3种防治措施的综合效益和综合成本进行计算和排序,作为选择豚草防治措施的准则.结果表明:豚草生物防治所获得的综合效益最高,综合成本最低;空白对照的综合效益最低,综合成本最高;化学防治的综合效益和综合成本居中.豚草生物防治效益成本比最高,说明其是一种最为理想的防治措施,值得推广应用.

Abstract: 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.
