Abstract
Objective] The study aimed to study carbon emission and the influence factors of carbon emission from various types of land in land use.[Method]Taking Gansu province as a case, based on the analysis of land use structure change from 1995 to 2012, estimating the carbon emissions of various land use types and its influence factors are analyzed using LMDI model.Research shows that Overall, the change of land use structure from 1995 to 2012 illustrates an increasing trend of construction land area and a decreasing trend of farmland area .The in-ternal structure change of construction land for residential areas and mining land area is increasing, traffic land use changes significantly.1995-2012 general land use carbon emissions is on the rise, increased from 18.820 7 million tons in 1995 to 75.032 3 million tons in 2012, an average annual increase of 3.414 8 million tons.The largest carbon intensity of land use are residential areas and mining land areas, traffic carbon intensity is slowly rising, but fell by 2012.The change of land use, the improvement of economic development, the expand of popula-tion scale, enhance the land use carbon emissions.The promotion of energy efficiency and the optimization of energy structure inhibit land use carbon emissions.[ Conclusion] The residential and industrial sites have the greatest impact on the change trend of the total land use in Gansu province.Energy efficiency and energy structure optimization will be one of the important ways of carbon emission reduction in Gansu Province in the future.关键词
