[Analysis of Carbon Emission Characteristics and Influencing Factors of Different Land Use Types in Hunan Province].

It is important to explore the development path of urban low-carbon economies and formulate climate control policies to analyze the spatial and temporal evolution characteristics of land use carbon emissions and their influencing factors by accounting for carbon emissions from different land use types. Our study measured the carbon emissions of different land-use types in Hunan Province in 2010 and 2019. We used the OLS model to determine the influencing factors of land use carbon emissions based on the framework for land use carbon emissions using land use and cover and statistical data. The results showed that： ① Over 64% of the cities in Hunan Province had varying degrees of growth in total carbon emissions， with an east-high and west-low distribution. Specifically， the high-carbon emission cities were mainly located in the central part of Hunan Province with Loudi and Xiangtan as the center， spreading towards the north-south direction. ② Carbon emissions from energy consumption in construction land were the main source of carbon emissions in Hunan Province. More than 90% of the carbon emissions from construction land in cities accounted for 85% of urban carbon emissions， with some cities exceeding 95%. ③ The secondary and tertiary industries had consistently been the most significant contributors to the increase in carbon emissions， with their coefficients becoming larger despite minimal changes. In contrast， the primary industry consistently exerted a carbon-suppressing effect on emissions， with its coefficients also increasing but exhibiting substantial changes.
