摘要/Abstract

摘要： 明晰农田生态系统的碳汇量不仅对河南省实现碳达峰碳中和计划有着重要作用，而且也有益于指导河南省农业低碳可持续发展。然而，当前大多数碳汇核算研究都立足于单一方法的测算，缺乏多方法对比。基于第三次全国国土调查数据、河南省统计年鉴以及联合国政府间气候变化专门委员会评估报告中的参数数据等，采用净碳汇法和固碳速率法对河南省农田生态系统碳汇量进行核算，前一方法从碳吸收和碳排放角度核算河南省农田生态系统净碳汇，后一方法则主要考虑农田土壤生态系统净碳汇。结果表明，净碳汇法更适用于核算河南省农田生态系统净碳汇(以C计)，其值为354.00万t；同时，两种方法的测算结果均显示河南省农田生态系统呈碳汇特征。从空间上看，两种方法核算的碳汇分布情况呈现大体一致的规律，即由西北向东南方向逐渐增加。整体而言，该研究核算的河南省农田生态系统碳汇量远低于已有的研究结果，但对比河南省农田面积在全国占比所对应的碳汇量和已有研究，其更具合理性。

Abstract: Clarifying the carbon sink of cropland ecosystem not only plays a significant role in the realization of the carbon neutralization plan for Henan Province, but also provides the helps for low-carbon and sustainable agriculture development. However, current studies on the carbon sink accounting are mainly based on only one single calculation method, lacking of multiple methods comparison. Based on the data of the Third National Land Survey, Statistical Yearbook of Henan Province, and the parameter data in the assessment report of the United Nations Intergovernmental Panel on Climate Change, the net carbon sink method and the carbon sequestration rate method were used to assess the carbon sink of cropland ecosystem in Henan Province. The net carbon sink method estimated the net carbon sink from the perspective of carbon absorption and carbon emission, while the carbon sequestration rate method mainly considered the net carbon sink of cropland soil. The results show that the net carbon sink method is more suitable for calculating the carbon sink of cropland ecosystem in Henan Province, and its value was 3.54 million t C; Meanwhile, the calculation results of the two methods all show that the cropland ecosystem in Henan Province is a carbon sink. Spatially, the distribution of carbon sinks estimated by the two methods presented a generally consistent law, that is, it gradually increased from the northwest to the southeast. On the whole, the carbon sinks of cropland ecosystem in Henan Province estimated in this study are far lower than the results of the previous studies, but it is more reasonable compared with the corresponding carbon sink of the proportion of Henan Province to the national cropland area.

Key words: cropland, ecosystem, carbon sink, net carbon sink, carbon sequestration rate
