Abstract

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.
