宁夏市域尺度下畜牧业碳排放时空演变及驱动因子研究

Study on the Spatial and Temporal Evolution of Carbon Emissions from Animal Husbandry and the Driving Factors at the Municipal Scale in Ningxia

以宁夏5个市2001—2020年畜牧存栏统计数据为基础,探究畜牧养殖业碳排放的时空变化规律及驱动因子。结果表明,2001—2020年宁夏各市畜牧业碳排放总体呈增长趋势。在相同时限内,固原市和吴忠市碳排放增幅较大,石嘴山市增幅相对稳定。碳排放量主要受政策、经济、技术、行业因素影响。

Based on the statistical data of animal husbandry inventory in five cities in Ningxia from 2001 to 2020,this study explores the spatiotemporal variation patterns and driving factors of carbon emissions from animal husbandry.The result showed that the overall trend of carbon emissions from livestock farming in Ningxia cities from 2001 to 2020 was increasing.Within the same time frame,carbon emissions increased more in Guyuan City and Wuzhong City,while the increase in Shizuishan City was relatively stable.Carbon emissions were mainly influenced by policy,economic,technological and industry factors.
