    Establishment on the loss evaluation index system of Hyphantria cunea Drury's invading China

    • 摘要: 美国白蛾不仅破坏自然资源的物质量,而且制约了寄主植物多种功能的充分发挥,对人们的视觉、心理和日常生活等方面造成了损失.以往的文献通过森林资源等实物变化来认识美国白蛾造成的危害,忽视了社会和经济属性,且危害程度的量化研究较少,并未使社会各界充分认识到其危害与损失.目前迫切需要科学定量评估美国白蛾入侵我国造成的损失,客观反映美国白蛾造成的损失与人类、社会之间的关系.该文遵循科学性、系统性与可比性等原则,结合美国白蛾的自身特点,在对美国白蛾入侵危害及损失进行系统研究的基础上,首次系统构建了较为完善的美国白蛾损失评价指标体系,共计47个指标,其中包括2个一级指标,9个二级指标,27个三级指标,并阐述了主要指标的内涵及其测度方法.

       

      Abstract: Hyphantria cunea Drury not only damages natural resources,but also limits the multi-functions of host-plants.In addition,it causes the great loss of human eyesights,psychology and everyday life,etc.Past studies recognized its damage only through the changes of materials such as forest resources,ignoring its social and economic nature.And at present,the researches on its loss evaluation are not adequate,especially lacking of quantitative analysis,and the common concern from the whole society is not brought forward.Therefore,it is in great need to analyze and evaluate the damage and loss systematically and scientifically caused by H.cunea.In accordance with scientific,systematic and comparable principles,combining its own characteristics,the paper firstly identified the sorts of damage and loss caused by this invasive species.Then the index system of its loss evaluation was set up,up to 47 indices,including two first-level indices,nine second-level ones and 27 third-level ones,and the connotation of main indices was elaborated for the first time.Based on the indices,the study also established the measuring methods.
