为满足决策支持系统对桉树枝瘿姬小蜂虫害风险评估及获取量化结果的需要,根据已知桉树枝瘿姬小蜂生物学性状和传播规律,建立了桉树枝瘿姬小蜂虫害风险模糊评价体系,提出了基于模糊综合评价的虫害风险评估方法。利用该方法对广西黄冕林场一新增桉树项目进行了虫害风险评估,并分析了不同虫害预防措施的效果,所得结果与事实吻合。这表明,该方法是一种有效的桉树枝瘿姬小蜂虫害风险评估方法。
In order to meet the need of decision support system for assessing the risk of pest insects in Eucalyptus chinensis and the quantification results, according to the biological characteristics and propagation rules of the bugs, the fuzzy evaluation of pest risk of Eucalyptus chinensis System, a risk assessment method based on fuzzy comprehensive evaluation was proposed. The method was used to evaluate the pest risk of a newly-added eucalyptus plantation in Huangmian Forest Farm, Guangxi. The effects of different pest precautionary measures were analyzed. The results obtained were in good agreement with the facts. This indicates that this method is an effective method for assessing insect pest risk of Eucalyptus chinensis.
