摘　　要：以杭州市域为案例,运用数据包络分析方法中基于投入导向的C2R-I模型,将林地利用中不同类型的林地利用数量作为投入,将森林固碳总量作为最终产出,结合全面的历史统计资料查证与实地校验,对我国区域林地利用数量变化的碳源汇效应进行了测度与实证研究。研究结论表明,林地利用数量变化的碳源汇效应评价是可行的,区域林地利用数量变化的碳源汇效应变化同其经济发展水平具有高度的相关性,这说明经济增长方式转变是区域林地利用数量变化的碳源汇效应可持续发展的动力源泉。该研究结论不仅对区域林地利用数量变化的碳源汇效应研究具有理论贡献,而且可以从碳循环调控的角度为区域低碳经济发展的模式选择与发展战略提供科学依据。Take Hangzhou as the example,select C：R-I model based on date envelopment analysis（DEA）,which adopt the forestland used in different types as the number of inputs and the total forest carbon sinks as a final output, combined with comprehensivehistorical historal statistics and field calibration, this paper analyzes the car- bon sinks efficiency of the regional forestland use quantity.The results are as follows： firstly, the results show that the measure and evaluation of the efficiency of carbon sinks of forestland use quantity is feasible; sencondly, the results show the carbon sink efficiency of the regional forestland use quantity changes with its level of economic development, which indicates that the sustainable development of economic is the source of the carbon sequestra- tion efficiency of the regional forestland use quantity;thirdly, the findings of this paper not only gives a theoreti- cal contribution to the carbon sequestration efficiency of the regional forestland use quantity, but also provides a scientific basis for the development mode selection of regional low-carbon economy from the perspective of the carbon cycle regulation.
