摘要由于地处华北平原,郑州市域内农田面积较多,约占44.40%,而森林和城市绿化面积相对较少。目前,我国的碳汇主要估算对象是林业资源,常常忽略了农田和城市绿化碳汇资源。为全面了解郑州市全口径碳汇情况,利用郑州市的统计数据,估算了郑州市森林碳汇(乔木林、竹林、经济林、灌木林等)、农田碳汇(小麦、玉米、蔬菜、瓜果等)和城市绿化碳汇(乔木和灌木)。研究结果表明,郑州市农田碳汇量约为146.05万吨,作为主要农作物的小麦和玉米贡献最大,约占73.19%;人工林树种(如杨树、泡桐等)对森林碳汇贡献最大,约占48.81%,森林碳汇总量约为21.68万吨;城市绿化碳汇量约为22.89万吨,行道树类别的栾树、银杏、悬铃木等贡献较多,约占51.16%。因此,在进行郑州市碳汇估算时,若忽略农田和城市绿化碳汇资源,碳汇结果将被严重低估。

Abstract：Located in North China Plain, Zhengzhou has a large area of farmland, accounting for about 44.4%, while forest and urban green area are relatively small. Currently, the forest resources are the primary target of carbon sink estimation in China, while urban green and farmland resources usually have been ignored. In order to completely consider all carbon sink resources in Zhengzhou, the carbon sink of forest (e.g. arbors, bamboo, shrub, economic forests), farmland (e.g. wheat, corn, vegetables, fruits) and urban green (arbors and shrub) had been estimated in the study, using the statistics of Zhengzhou. The results showed that farmland carbon sink in Zhengzhou was about 1.46million tons, and wheat and corn, as the main crops, contributed the most (approximately 73.19%). Man-made forest (e.g. poplar, paulownia) had the maximum contribution to the forest carbon sink, accounting for 48.81%, and the total forest carbon sink in Zhengzhou was about 0.22million tons. The urban green carbon sink was about 0.22million tons. The carbon sink of street trees, such as goldraintree, ginkgo, sycamore, were the biggest part of the urban green carbon sink in Zhengzhou, which was approximately 51.16%. Therefore, when estimating carbon sink in Zhengzhou, the carbon sink result would be seriously underestimated, if the farmland and the urban green carbon sink resources were ignored.
