[Objective] The decoupling relationship between land-use carbon emissions and economic development， and the influencing factors were explored， in order to provide a theoretical basis for better aligning urban carbon reduction strategies with economic growth in the first batch of low-carbon pilot cities in China. [Methods] Taking the first batch of 8 low-carbon pilot cities （nemely Tianjin， Chongqing， Shenzhen， Xiamen， Hangzhou， Nanchang， Guiyang and Baoding cities） as the study area， the evolution trend of land-use carbon emissions in the pilot cities from 2005 to 2020 were analyzed. Based on the Tapio decoupling model， the decoupling relationship between land-use net carbon emissions and economic development was explored， and the influencing factors of net carbon emissions from land use were investigated by employing the logarithmic mean divisia index （LMDI） method. [Results] ① The net carbon emissions of the first batch of low-carbon pilot cities during 2005—2020 showed a rapid growth trend， increasing from 7.74×10⁸ tons in 2005 to 1.80×10⁹ tons in 2020. ② The overall decoupling index of the pilot cities gradually decreased during the study period， indicating that the dependence of economic development on land-use carbon emissions was on a downward trend. During the period from 2015 to 2020， the land-use carbon emissions of Tianjin City presented a desirable strong decoupling state from the economic development， while Baoding City showed an undesirable expansive negative decoupling state， and the remaining six cities showed a weak decoupling state. This reflected that there were still considerable potential for improvement in coordinating the relationship between land-use carbon emissions and economic development in the pilot cities. ③ Positive factors affecting land-use carbon emissions in descending order were： economic development level > land use structure > population density > total land area； negative factors were ranked as follows： economic efficiency of land use > carbon emission intensity of land type. [Conclusion] The decoupling status and the influencing factors of land-use carbon emissions in pilot cities varied significantly across regions， thus regionally differentiated low-carbon economic development strategies should be formulated in combination with the influencing factors.
