摘　　要：运用机会成本法、影子价格法对2001和2005年我国平原林业净化空气和固碳释氧价值进行核算。结果表明:1)2001和2005年我国平原林业净化空气和固碳释氧的总价值分别为14 609.23亿和18 739.27亿元。2005年,东北区、华北区、华东区、中南区、西南区和西北区平原林业的净化空气价值分别为2 574.96亿、2 975.93亿、5 285.94亿、3 172.19亿、316.43亿和1 238.33亿元,固碳释氧价值分别为906.30亿、426.35亿、838.49亿、665.25亿、52.04亿和287.06亿元;2)平原林业净化空气和固碳释氧总价值排序为华东区>中南区>东北区>华北区>西北区>西南区。平原林业在净化空气和固碳释氧方面的生态服务功能价值相当可观,应该大力推进平原地区林业生态工程的建设步伐和管理水平,对改善我国平原地区空气质量,增加林业碳汇功能具有重要意义。The capacity of plain forestry purifying air purification,fixing carbon and releasing oxygen of forestry in 2001 and 2005 were measured by methods of opportunity cost,shadow price,etc.The results indicated that 1） the total values of air purification,carbon fixation and oxygen release in 2001 and 2005 were 1.46×1012 and 1.87×1012 Yuan respectively.In 2005,the values of air purification in the northeast zone,the Chinese north zone,the Chinese east zone,the central south zone,the southwest zone,the northwest zone of China were 2.57×1011,2.97×1011,5.29×1011,3.17×1011,3.16×1010 and 1.24×1011 Yuan respectively,while the values of carbon fixation and oxygen release were 9.06×1010,4.26×1010,8.38×1010,6.65×1010,5.20×109 and 2.87×1010 Yuan respectively.2） The descending order by the total values was sorted as： the Chinese east zone,the central south zone,the northeast zone,the Chinese north zone,the northwest zone,and the southwest zone.Based on such tremendous values,construction and management of plain forestry in China should be advocated to solve the problem of air pollution and increase forestry carbon sinks of plain areas in China.
