摘　　要：作为全球碳循环和当前低碳发展的重要组成内容之一,城市碳汇资源研究受到广泛关注.以高度城市化的深圳市为例,利用IPCC缺省碳汇系数法和相关研究模型,分析了城市碳汇资源的基本特征.结果显示:深圳市2005年碳汇总量约为347.85×104 t,其中林地、耕地、草地、湿地和海洋的碳汇总量分别为317.52×104、4.50×104、2.10×104、12.60×104和11.13×104 t.碳汇资源持续减少、碳汇资源量较低、碳汇品质较差、碳汇资源保护形势严峻、碳汇能力提升压力较大等是当前深圳碳汇资源的主要特征,表明要推动高度城市化地区低碳生态城市建设,必须重视城市碳汇资源相关工作的开展,促进碳汇资源持续增加和碳汇品质持续提升.结合深圳城市发展实际,从碳汇资源保护、碳汇资源建设、碳汇品质提升、碳汇服务交易等角度提出了深圳城市碳汇资源提升的主要策略.Taking the highly urbanized city of Shenzhen as an example,the IPCC default factor method and carbon sink model were adopted to analyze the basic characteristics of the urban carbon sink resources.The results revealed that the total carbon sinks in Shenzhen City totaled about 3,478,500 tons in 2005,of which 3,175,200 tons,45,000 tons,21,000 tons,126,000 tons,and 111,300 tons were stored in forest land,farmland,grass land,wet land,and seas,respectively.The main characteristics of Shenzhen＇s current carbon sink resources are that they are constantly being reduced,they are of inferior quality,the protection situation issevere,and there is great pressure for capacity improvement.The results demonstrated that in order to promote the construction of a low carbon and ecological city in highly urbanized areas,work related to urban carbon sink resources must be carried out to ensure sustained increase of carbon sink capacity and continuous enhancement of the carbon sink quality.Based on the real situation in Shenzhen,strategies for improving Shenzhen＇s carbon sink resources were proposed from the perspectives of carbon sink protection,carbon sink construction,carbon sink quality enhancement and carbon sink service trade.
