阿克苏河流域土地利用碳排放时空演变
Spatial and Temporal Evolution of Land Use Carbon Emissions in Aksu River Basin
摘要
Abstract
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 15.32×104 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's I value increased and then decreased,and it was generally in a state of aggregation.There was a strong overall positive correlation between land use and carbon emissions,and it was spatially in a high-value aggregation state.关键词
