摘　　要：基于2005、2010、2015年杭州市县域单元土地利用数据和能源消耗数据,分析了土地利用碳排放的时空演变特征,并利用LMDI因素分解法对土地利用碳排放的影响因素进行分析。结果表明:杭州市土地利用碳排放逐渐增加,城镇用地、农村居民点用地和工业及其他建设用地的碳排放量逐渐增加,耕地碳排放在减少。从土地利用碳排放结构看,工业及其他建设用地的碳排放量最大,其次为城镇用地、耕地和农村居民点用地。不同县域单元土地利用碳排放结构及变化不尽相同。杭州市城镇用地和工业及其他建设用地碳排放呈现东北高、西南低的空间分布特征;农村居民点用地碳排放呈现东北高和西南高、中部低、主城区最低的空间分布特征;耕地碳排放呈现东北高、西南低、主城区最低的空间分布特征。总体上,土地利用变化和土地利用集约度对土地利用碳排放起抑制作用,经济发展因素和人口因素起促进作用,但不同因素在不同时期、不同县域单元的作用强度和作用方向不尽相同。Based on the land use data and energy consumption data of each county in Hangzhou in 2005,2010 and 2015,the spatial and temporal evolution characteristics of land use carbon emissions were analyzed,and the influencing factors of land use carbon emissions were analyzed using LMDI model.The results show that:The total land use carbon emissions in Hangzhou were gradually increasing.The carbon emissions of urban land,rural residential land and industrial and other construction land were gradually increasing,while the carbon emissions of cultivated land were decreasing.From the perspective of the structure of land use carbon emission,industrial and other construction land had the largest carbon emissions,followed by urban land,cultivated land and rural residential land.The structure of land use carbon emission and its change in different counties were not the same.The carbon emissions of urban land and industrial and other construction land in Hangzhou showed the spatial distribution characteristics of high in the northeast and low in the southwest.The carbon emission of rural residential land showed the spatial distribution characteristics of high in the northeast and southwest,low in the middle and lowest in the main urban area.The carbon emission of cultivated land showed the spatial distribution characteristics of high in the northeast,low in the southwest and lowest in the main urban area.(3)In general,land use change and intense land use restrained land use carbon emissions,while economic development and population growth promoted land use carbon emissions.But the action intensity and its direction of different factors in different periods and counties were different.
