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.

Key words： metrology all carbon sink resources urban carbon sink carbon summary estimates vegetation carbon stock non-forest carbon sink resources
