摘　　要：系统分析土地利用碳排放时空演变特征,为促进碳排放功能协调发展提供科学依据和决策参考。基于土地利用数据及能源排放数据,采用碳排放系数法和空间自相关分析法,探究阿克苏河流域土地利用碳排放时空演变特征。结果表明:1990—2020年流域净碳排放量呈显著增加趋势,增加了15.32×10^(4)t,年均增长率为6.62%,其增长趋势分为缓慢增长阶段、快速增长阶段、小幅增长阶段;重度排放区域集中在流域东部,中度排放区域集中在乌什县,轻度排放区域集中在流域中部,微度排放区域逐年减少,至2020年仅剩阿合奇县;全局Moran’s Ⅰ值呈增大后减小趋势,总体上处于聚集状态。土地利用碳排放正相关性整体较强,空间上处于高值聚集状态。The spatial and temporal evolution characteristics of land use carbon emissions were systematically analyzed to provide scientific basis and decision-making reference for promoting the coordinated development of carbon emission function.Based on the land use data and energy emission data,the carbon emission coefficient method and spatial autocorrelation analysis method were used to explore the spatial and temporal evolution characteristics of carbon emission from land use in Aksu River Basin.The results showed that:the net carbon emissions of the basin increased significantly from 1990 to 2020,increasing by 15.32×10^(4) t,with an average annual growth rate of 6.62%,and its growth trend was classified into a slow growth stage,a rapid growth stage,and a small growth stage;the heavy emission area was concentrated in the eastern part of the basin,the moderate emission area was concentrated in Wushi County,the mild emission area was concentrated in the middle of the basin,and the slight emission area was decreasing year by year;the overall Moran’sI value increased and then decreased,and it was generally in a state of aggregation.Therewasastrong overall positive correlation between land use and carbon emissions,and it was spatially in a high-value aggregation state.
