松毛虫危害的生态经济损失内容及评估指标体系构建探析

在查阅现有相关文献的基础上,结合松毛虫危害发生的实际情况,首先对松毛虫危害所引发的生态与经济损失的主要内容进行了系统地分析和论证,包括林产品、景观价值、农业、畜牧业、渔业、人类健康、涵养水源、保持水土、防风固沙、净化空气、调节气候、固碳制氧、生物多样性保护等11个方面的损失;接着构建了松毛虫危害的生态经济损失评估指标体系,其中共包括2个一级指标、4个二级指标、13个三级指标和26个四级指标。

The Analysis of the Eco-Economic Losses Content and Evaluation Index System of the Pine Caterpillars

On the base of consulting the existing literature,and combining with the occurring situation of the pine caterpillars,this article firstly systematically analyzes and demonstrates the main content of the eco-economic losses caused by the pine caterpillars,including 11 aspects of the losses:forest product,landscape value,agriculture,animal husbandry,fishery,human health,water conservation,soil and water conservation,windbreak and sand-fixation,purifying air,regulating climate,carbon sequestration and oxygen production,protecting biodiversity,etc;then constructs the index system of the eco-economic losses evaluation of the pine caterpillars,including 2 first-level indexes,4 second-level indexes,13 third-level indexes,26 fourth-level indexes.
