摘　　要：根据雨雪冰冻灾害森林资源受灾面积、受灾程度以及我国相关领域的研究工作,采用森林生态系统服务功能评估规范,对此次雨雪冰冻灾害受损森林生态系统保育土壤、涵养水源、森林固碳和生物多样性进行初步评估。结果表明:此次雨雪冰冻灾害造成生态系统服务功能损失的价值为7117亿元,各项服务功能价值量损失排序为水源涵养>森林碳储量>生物多样性>森林年固碳能力>保育土壤;从各省份雨雪冰冻灾害森林生态系统服务功能损失价值来看,江西与湖南最大,分别为1499.8亿元和1463.75亿元,江苏、陕西和青海最小,分别为58.96亿元、53.42亿元与1.06亿元;从各省份雨雪冰冻灾害不同树种生态服务功能受损情况来看,马尾松、杉木最为严重,马尾松林生态服务功能损失价值为1570.16亿元,不同树种生态服务功能损失价值排序为马尾松>杉木>阔叶树>竹林>其他树种>经济林树种>湿地松>桉树。Based on the data of the area and grade of the damaged forest resources by frozen rain and snow disaster,as well as on the relevant researches,the forest ecosystem services standardized assessment criterions were used to estimate the erosion control,water storage,C fixation and biodiversity conservation of the forest ecosystem in the south China.The result indicated that frozen rain and snow disaster caused a loss of ecosystem services valued 711.7 billion RMB.The value loss of various service functions ranked as：water storage 〉 C storage 〉biodiversity conservation 〉 C fixation 〉erosion control.Comparing the value order of ecosystem services damaged in different provinces in the south China,Jiangxi and Hunan lost the most of value,that were 149.98 billion RMB and 146.375 billion RMB;Jiangsu,Shaanxi and Qinghai lost the least of value,that were 5.896,5.342 and 0.106 billion RMB respectively.The value losses of Masson Pine and Chinese Fir were the most serious and the value loss of Masson Pine was up to 157.016 billion RMB.The value loss of service functions in different species ranked as：Masson Pine 〉 Chinese Fir 〉broad-leaved tree 〉bamboo〉 other tree species〉economic forest tree〉 Slash Pine〉eucalyptus.
