| 摘 要： | 为分析陕西关中地区测土配方施肥项目减少温室气体排放的潜力，以陕西省CDM项目中渭南市临渭区测土配方施肥项目为例，采用IPCC2006中N2O排放量计算方法和测土配方施肥固碳减排计量方法指南中土壤碳储量计算方法，从氮肥施用、土壤碳固定，农作物产量改变3个方面对该地区测土配方施肥项目温室气体减排潜力进行综合分析和估算。该项目共涉及临渭区3个乡镇17个项目村，共计农田面积2 818.89 hm。结果表明：测土配方施肥的使用，不但可以减少氮肥施用量，提高农作物产量，增加土壤碳储量，而且能够减少农田温室气体的排放。项目实施后，每公顷农田每年可减少温室气体排放1 206.93~1 484.18 kg CO2当量，项目年温室气体减排量为3 660.95 t CO2当量。

| Abstract: | In order to analysis the reduction potential of greenhouse gas emission under recommended fertilization project in the central shaanxi plain, taking Weinan Linwei recommended fertilization project of CDM project in shaanxi province as a case study, the methods of nitrous oxide emission of IPCC2006 and soil carbon storage calculation method of the Method Guideline for Quantifying Carbon Sequestration and Reduction in Greenhouse Gas Emission Under Recommended Fertilization were used to comprehensive analyze and estimate greenhouse gas emission reduction potential of recommended fertilization project by the aspects of using nitrogenous fertilizer, soil carbon sequestration and crop yield change. The project involved in 2 818.89 hmfarmland in 17 villages of 3 towns. The results indicated that using recommended fertilization not only reduced quantity of nitrogen fertilizer, increased crop yield and soil carbon storage, but also reduced farmland greenhouse gas. After the implementation of the recommended fertilization project, farmland could reduce greenhouse gas emission of 1 206.93-1 484.18 kg CO2 equivalent per hectare annually and greenhouse gas emissions of 3 660.95 t CO2 equivalent was reduced annually for the project. |
