摘要
通过研究林地、水稻田、园地、草地、湿地和城市绿地六类绿地的碳源排放/汇清除,构建城乡生态绿地的碳汇功能评估模型,并以北京市延庆县为例,对城乡生态绿地空间的碳汇能力进行量化评估.结果表明:2010年延庆县城乡生态绿地的碳排放总量为0.06万t CO2e,汇清除总量为135.20万t CO2e,净汇清除量为135.14万t CO2e.研究结果将有助于深入理解生态绿地空间的碳汇功能,为实现城乡绿地空间的合理布局、推进低碳城市建设提供科学依据.
By studying the carbon emissions / removals of six types of greenland,including forest,rice fields,garden, meadows,wetlands and urban green space,the urban and rural ecological greenland carbon sink assessment model has been buih.The carbon sink capacity has been calculated based on this model in Yanqing County,Beijing.The results showed that：Yanqing rural ecological green carbon emissions was 600 t CO2e,removals total was 1 352 000 t CO2e, the net carbon sinks was 1 351 400 tCO2e in 2010.This article will help us to understand ecological green space carbon sink,and provide a scientific basis for the realization of rational distribution of urban green space and promoting low-carbon urban construction.
