摘要
采用Costanza等人的生态系统服务评价方法,对兰州市区植被生态系统的调节气候、固碳释氧、涵养水源、净化环境和减弱噪声等四项服务功能进行评估。结果表明,2000年,兰州市植被生态系统服务功能价值为1.64×109元。同时,城市植被生态系统各生态服务功能价值大小依次为:固碳释氧、调节气候、净化环境、减弱噪声、涵养水源。净化环境和减弱噪声是兰州市下阶段城市植被规划设计中需要重点保障的生态系统服务功能。
The economic value of urban vegetation ecosystem service in Lanzhou was studied using the ways that Costanza et al evaluated ecosystem services. Five functions of ecosystem service was analyzed such as fixing carbon and releasing oxygen, conditioning climate, keeping waterhead, purifying environment, and restraining noises. The result showed that the urban vegetation ecosystem services provided enormous ecological benefits with the total value of RMBI. 34 ×10^9 in 2000, The function of conditioning climate is the most important, the function of fixing carbon and releasing oxygen is the second, the functions of purifying environ- ment, restraining noises and keeping waterhead are the last important. As for the case study in Lanzhou, the functions of restraining noises and purifying environment are in great need of protection in urban landscape management and ecological construction.
