森林在全球陆地碳循环中起着决定性作用,而碳储量和碳循环监测是生态系统碳汇研究的基础.本文通过建立深圳市森林碳储量和碳循环的监测方法,选取深圳市山地森林、园林绿地和红树林中具有代表性的森林群落样方,进行碳储量和碳循环的实地监测,开展深圳市典型森林群落的碳密度和碳循环评估.碳密度监测结果表明:马尾松林、杉木林、针叶混交林、湿地松林、常绿阔叶林、针阔混交林、荔枝林、灌木林、榕树林、棕榈树林和红树林等11个具有代表性的群落样方,其生态系统碳密度在65.09～257.31 t·hm-2之间,其中,红树林的生态系统碳密度最大,为257.31 t·hm-2,其次为常绿阔叶林和针阔混交林,分别为117.48 t·hm-2和105.46 t·hm-2,灌木林的生态系统碳密度最小,为65.09 t·hm-2.群落生态系统碳循环研究结果表明,11种群落样方的净生态系统生产力(即碳汇量)在0.02～3.37t·hm-2·a-1之间,因此,研究中所选取的11个深圳市典型群落类型均表现为碳汇,其中,红树林的年碳汇量最大,为3.37 t·hm-2·a-1,其次为常绿阔叶林和针阔混交林,分别为2.09t·hm-2·a-1和2.66 t·hm-2·a-1,相当于红树林的60％左右,园林绿地和灌木林的碳汇量较小,仅在0.02～0.08 t·hm-2·a-1之间碳汇资源评估不但可以为碳排放交易市场的建立提供重要的数据和技术支撑,而且可以为低碳城市发展提供重要的决策依据.
