摘要 综述国内外生态系统服务功能价值评估相关研究进展,以深圳市为例,运用生态经济学原理与方法,阐释了生态系统调节气候、固碳释氧、保持土壤、涵养水源、净化环境和减弱噪声等生态服务功能,对其经济价值进行评估.结果表明,深圳市生态系统服务功能具有巨大的生态经济效益,2000年总价值为1 265.29亿元,与深圳市当年国内生产总值1 665.24亿元相当.同时,城市生态系统各生态服务功能的重要性,由大到小依次为固碳释氧功能、调节气候功能、涵养水源功能、保持土壤功能、净化空气功能与减弱噪声功能.而减弱噪声与净化空气是深圳市下一阶段景观管理与生态建设中需要重点保障的生态系统服务功能. Based on research progress on economic value of ecosystem services, taking Shenzhen for instance, the authors analyze the functions of ecosystem services such as conditioning climate, fixing carbon and releasing oxygen, preserving soil, keeping waterhead, purifying environment, and restraining noises. Economic values of all the six kinds of ecological service functions are calculated. The results show that ecosystems in Shenzhen provide enormous ecological economic benefits with the total value of RMB 126292000000, which corresponds with the RMB 166524000000 of GDP of Shenzhen in 2000. Meanwhile, the importance of different ecosystem services in urban areas is different. The function of fixing carbon and releasing oxygen is the most important, the function of conditioning climate is the second, and the functions of keeping waterhead, preserving soil, purifying environment, and restraining noises are the last important. As for the case study in Shenzhen, the functions of purifying environment and restraining noises are in great need of protection in urban landscape management and ecological construction.
