摘　　要：根据环境经济学的原理与方法,建立冰冻灾害造成森林生态功能价值损失经济评估的指标体系,并确定各项指标的评估方法;提出通过定量和半定量折算的方式计算出各项评估指标值,将造成的生态功能价值损失以货币数值形式反映出来,实现定量评价的目标;同时,以福建省受灾森林为例,对冰冻灾害造成森林生态功能价值的经济损失进行实证评估。结果表明:2008年冰冻灾害造成福建省森林涵养水源、保育土壤、固碳释氧、净化空气、保护生物多样性等功能方面的价值损失分别为107.906,80.228,52.617,27.782和0.720亿元·a-1,共造成生态服务价值的间接经济损失达到269.253亿元·a-1,给福建省林业造成直接提供产品价值的经济损失为45.975亿元。说明冰冻灾害造成森林间接使用价值的损失远大于森林直接提供产品价值的损失。Firstly,the assessment index system for the economical loss brought by the blizzards and frozen to the forest ecosystem in the functional value of ecological environment services were established and the estimating methods for the various index were ascertained,according to the principles and methods of environmental economics.And then put to calculate the value of assessment indicators through the methods of quantitative and semi-quantitative converting,in order to reflect the loss of ecological functions value in the monetary form and achieve the goal of quantitative evaluation.At the same time,evaluated empirically the value loss,taking the disaster-stricken forest in Fujian province as an example,the results show that the indirect economic loss brought by 2008＇ blizzard and frozen disasters to Fujian provincial forest in water conservation,soil conservation,carbon sequestration release oxygen,purify air,biodiversity conservation,and other ecological functions value were 10.790 6,8.022 8,5.261 7,2.778 2 and 0.072 0 million yuan yearly,a total of the indirect economic loss in the value of ecosystem services reached 26.925 3 billion yuan yearly,and the direct economic loss brought by 2008 blizzard and frozen disasters to Fujian provincial forestry in provision of forest products is 4.597 5 billion yuan.The results indicated that the indirect use value loss of forest in ecological environment services is far greater than the value loss of the direct provision of forest products.
