河南省农业农村碳排放测度及其时空格局分析

Measurement and Spatiotemporal Pattern Analysis of Carbon Emissions from Agriculture and Rural Areas in Henan Province

为探讨河南省农业农村碳排放时序特征及空间格局,基于IPCC(2006)提出的碳排放因子估算法对河南省2000—2020年农业农村碳排放进行估算,同时运用ArcGIS 10.6软件对河南省各市农业农村碳排放空间格局趋势进行分析。结果表明:河南省2000—2020年农业农村碳排放整体呈先上升后下降的倒“U”曲线趋势,农业农村碳排放结构中畜牧养殖业是第一源头,农村居民能源消费碳排放是第二大碳源。从空间格局来看,河南省各地区的碳排放量参差不齐,碳排放情况整体上由北向南,自西向东逐渐增多。但是,2000—2020年间河南省各地区的碳排放量整体上大致呈下降趋势。研究建议河南省要重视畜牧业的碳减排问题,大力推进畜牧业绿色低碳发展,以科技进步为引擎坚持适度农业机械化、科学施肥,坚持政策引导鼓励使用清洁能源替代高碳排放能源。

In order to explore the temporal characteristics and spatial pattern of carbon emissions from agriculture and rural areas in Henan Province,the carbon emission factor estimation method proposed by IPCC(2006)was used to estimate the carbon emissions from agriculture and rural areas in Henan Province from 2000 to 2020.At the same time,ArcGIS 10.6 software was used to analyze the spatial pattern trend of carbon emissions from agriculture and rural areas in various cities in Henan Province.The results show that from 2000 to 2020,the overall carbon emissions from agriculture and rural areas in Henan Province showed an inverted“U”curve trend of first increasing and then decreasing.In the carbon emission structure of agriculture and rural areas,animal husbandry is the first source,and rural residents'energy consumption carbon emissions are the second largest carbon source.From the perspective of spatial pattern,the carbon emissions in various regions of Henan Province are uneven,and the overall carbon emissions gradually increase from north to south and from west to east.However,from 2000 to 2020,the overall carbon emissions in various regions of Henan Province showed a downward trend.Research suggests that Henan Province should pay attention to carbon reduction in animal husbandry,vigorously promote green and low-carbon development of animal husbandry,use technological progress as the engine,adhere to moderate agricultural mechanization and scientific fertilization,and adhere to policy guidance to encourage the use of clean energy to replace high carbon emitting energy.
