摘　　要：城市森林有着改善城市生态环境的巨大作用,对城市森林的生态效益进行评价,就能对它的价值量有一个准确客观的认识,并能够更好地规划城市森林资源分布、制定合理的生态公益林补偿政策和森林经理措施。对城市森林的生态效益种类和森林生态效益评价的理论基础做了初步研究,探讨了南京市城市森林固碳制氧效益的评价方法,以及借助这些方法建立起来的固碳制氧效益评价模型,并进行固碳制氧效益价值和对全球碳平衡贡献价值的量化和计算。研究结果表明:阔叶林的固碳制氧价值最大,为2.99亿元,针叶林以2.62亿元次之,针阔混交林则最低,仅为0.23亿元。考虑南京市针阔混交林面积比较少,建议对阔叶林和针叶林加以改造,以形成既能增加单位面积碳释氧价值功能、又能增加土地肥力、改善环境、抗病虫害、可持续利用的高效针阔混交林。Urban forest which can provide ecological and environmental services, is a useful instrument to tackle with the urban environment degradation caused by the rapid urbanization processes. Now it is critically important to make an accurate assessment of ecological benefits provided by urban forest to implement sound urban forestry projects and urban forestry policy. This paper deal with the evaluation of fixing carbolic and manufacturing oxygen with the biomass-carbolic- oxygen models and history forest resource inventory data. The result shows that the average annual value of fixing carbolic and manufacturing oxygen by urban forests in Nanjing is 0. 584 billion Yuan, in which the broadleaf forest has the most contribution （0. 299 billion Yuan）, and then the coniferous forest （0.262 billion Yuan）. The mixed conifer and deciduous forest is only 0. 023 billion Yuan because of scarcity in area and biomass. It is suggested that in order to both improve the fertility of forest soil and increase fixing carbolic and manufacturing oxygen value, both broad leave forest and coniferous forest should be reconstructed into the mixed conifer and deciduous forest.
