摘要
[目的]通过分析烟台市2000—2011年碳排放与经济发展之间的关系,为烟台市碳减排及发展低碳经济提供参考。[方法]基于土地利用碳源/碳汇研究的理论框架和计算模型,首先对烟台市土地利用、能源消费等数据进行分析,计算了不同土地利用类型的碳源/汇。然后利用Tapio脱钩模型分析该区碳排放与经济发展之间的脱钩弹性关系。[结果](1)建设用地是主要碳源,其面积与净碳排放量成倒U型库兹涅茨曲线关系。(2)林地为主要碳汇,其他用地影响较小且主要表现为碳汇。(3)烟台市净碳排放量在2001—2011年持续增长,年均增长率不断降低。[结论]烟台市碳减排工作已取得一定的成效,但减排形势依然严峻。其经济发展3个阶段(连接阶段、脱钩阶段Ⅰ和脱钩阶段Ⅱ)分别对应于其碳排放的高速增长、较快增长、稳定阶段这3阶段。
City from [-Objective] 2000 to 201 economy in this city. By exploring the links between carbon emissions and economic development in Yantai 1, and to provide the reference on carbon emission reduction and developing low-carbon [Methods] Based on the theoretical framework and estimation model of land-use chan- ges, carbon emissions in Yantai City were calculated through data analysis of its land use types and energy consumption. Then the relationship of them with respect to decoupling elasticity was analyzed by the use of the Tapio Decoupling model. [Results] （1） Construction land is the major carbon source in Yantai City, and the relationship between construction land area and the net carbon emissions presented an inverted U-shaped Kuznets curve. （2） Forest is the major carbon sink, and other land use types with less effect, are mainly regarded as carbon sinks. （3） Though the carbon emissions in Yantai City showed a continual increasing trend from 2000 to 2011, the increasing rate declined consistently. [-Conclusion] The work of carbon emission re- duction in Yantai City had achieved some success, but it is still under great pressure. The economic development in Yantai City can be divided into three stages according to the analysis of Tapio Decoupling model. The three stages are the connected phase, Decoupled stage Ⅰ and Decoupled stage Ⅱ , in corresponding to highest rate phase, higher rate phase and stabilized phase of carbon emissions in Yantai City, respectively.
