摘　　要：基于遥感数据,利用GIS,ESDA和GWR模型,分析东北三省2000—2018年土地利用动态变化、土地利用碳排放时空格局及空间相关性,进而分析其影响因素。结果表明:(1)2000—2018年,东北三省土地利用变化和土地类型相互转变明显。(2)2000—2018年东北三省土地利用净碳排放量呈不断上升趋势,增长率达31.3%;土地利用净碳排放区域差异显著,高值区集中在哈尔滨、齐齐哈尔、沈阳和大连,低值区集中在大兴安岭、长白山等山区。(3)Moran’s I指数呈先增后降趋势,整体呈现显著的空间正相关,局部热点区分布在辽宁省的阜新、锦州、鞍山、营口和大连,冷点区集中在黑龙江省的鹤岗、双鸭山、鸡西和佳木斯及吉林省的白山和通化。(4)东北三省土地利用碳排放影响因素从大到小依次为土地利用强度、工业结构、总人口。Based on remote sensing data,using GIS,exploratory spatial data analysis and GWR models,analyze land use changes and the spatial and temporal patterns and spatial correlation of carbon emissions in the three northeastern provinces from 2000 to 2018,and analyze their influencing factors to scientifically formulate regional carbon emission reduction measures.The results show that:①In the past 18 years,land use changes and land types in the three northeastern provinces have changed significantly.②From 2000 to 2018,the net carbon emissions from land use in the three northeastern provinces showed a rising trend,with a growth rate of 31.3%,the regional differences in net carbon emissions from land use were significant.In Suihua and Dalian,low-value areas are mainly concentrated in mountainous areas such as Daxinganling and Changbai Mountain.③The Moran’s I increased first and then decreased,showing a significant positive spatial correlation as a whole.The local hot spots are mainly distributed in Fuxin,Jinzhou,Anshan,Yingkou and Dalian in Liaoning Province,and the cold spots are mainly concentrated in Hegang in Heilongjiang Province,Shuangyashan,Jixi and Jiamusi,and Baishan and Tonghua in Jilin Province.④The influencing factors of land use carbon emissions in the three northeastern provinces in descending order are land use intensity,industrial structure and total population.Combining the results of the analysis of influencing factors,some suggestions are made for the formulation of carbon emission reduction measures in the three provinces of Northeast China.
