摘　　要：以珠三角区域绿道(省立)一号线为例,估算了绿道生态系统所具有的调节气候、固碳释氧、保持土壤、涵养水源、净化环境和减弱噪声6项服务功能的经济价值,并对绿道一号线不同城市段的6项服务功能价值进行比较。结果表明,省立绿道一号线生态系统服务功能总经济价值约为17.8亿元/a,调节气候和固碳释氧2项价值在总经济价值中所占比例较大。在一号线途经的5个城市中,广州段的服务功能价值总量最大。现阶段各城市段绿道控制范围内的建筑密度与规划纲要中的要求还有一定差距。Taking the Pearl River Delta Greenway Line One as an example,the authors estimate its ecosystem services value,includingclimate regulation,carbon fixation,oxygen generation,soil maintenance,water conservation,environment purification and noise control.Also,the authors have compared different city segments'ecosystem services value.The result shows that the ecosystem services value of Pearl RiverDelta Greenway Line One is about17.8billion yuan per year,of which,value of climate regulation and carbon fixation have large proportion.Guangzhou segment has the largest value among all five city segments.There is still a gap between current building density of all five citysegments and the building density standard required in PRD Greenway Planning Outline.
