摘　　要：为了研究郑州市不同种类园林植物的净碳汇及其经济价值,选择了具有代表性的13种乔木树种,8种灌木树种,5种草本植物,调查计算了这些植物的碳投入量,测定了这些植物的净生产力和碳含量,计算其净碳汇,用碳税法计算不同植物种类固碳价值。结果表明,乔木树种净碳汇的价值由大到小的顺序为:法桐、银杏、国槐、雪松、旱柳、女贞、广玉兰、黄山栾、白蜡、垂柳、龙柏、侧柏、紫叶李;灌木树种净碳汇的价值由大到小的顺序为:红叶石楠、小叶女贞、法青、黄杨、千头柏、月季、紫叶小檗、紫薇;草本植物净碳汇的价值由大到小的顺序为:菊花、鸢尾、葱兰、麦冬、早熟禾;不同类型园林植物的净碳汇的价值,乔木树种最大,其后依次为灌木树种、草本植物。建议在园林绿化中选择净碳汇较高的园林植物,减少园林绿地管理中农药与肥料的使用量,降低其碳投入,不断提高园林绿地空气净化功能。In order to study net carbon sink and economic value of different kinds of garden plants, thirteen arbor tree species, eight shrub tree species and five herb species were selected as the research materials in Zhengzhou city of Henan province, the carbon input, carbon content and net productivity of above plant species were measured. The value of net carbon sink of these plant species were evaluated using carbon tax method, then the value of net carbon sink of different plant types were calculated on the basis of above calculation results. The results showed that Platanus orientalis had the highest value of net carbon sink, followed by Ginkgo biloba, Sophora japonica, Cedrus deodara, Salix matsudana, Ligustrum lucidum, Magnolia Grandiflora, Koelreuteria bipinnata, Fraxinus chinensis, Salix babylonica, Sabina chinensis, Platycladus orientalis, Prunus cerasifera in the arbor tree species. Photinia serrulata has the highest value of net carbon sink, followed by Ligustrum quihoui, Viburnum odoratissimum, Buxus sinica, Platycladus orientalis, Rosa chinensis, Berberis thunbergii, Lagerstroemia indica in the shrub species. Dendranthema morifolium had the highest value of net carbon sink, followed by Iris tectorum, Zephyranthes candida, Ophiopogon japonicus, Poa annua in the herb species. The arbor tree species had the highest carbon input, followed by the shrub species, the herb species. It is suggested to select garden plants with high net carbon sink in landscape greening, the usage amount of pesticides and fertilizers should be reduced in landscape plant maintenance to improve the air purification function of garden green space.
