Greenhouse gas emission reduction has become the responsibility and consensus of all mankind’s development, the way of non-sustainable land use results in a lot of greenhouse gas emissions in the context of low-carbon economy. On the basis of revealing impact of land use on carbon emissions and status of carbon emissions, this paper proposes the regulation proposals of land use based on low-carbon emission: make carbon emission’s list of land use, optimize land use structure and layout, and strengthen land use control, intensive land use, soil and water conservation and ecological protection, management of agricultural land, woodland, grassland and wetland, control the scale of construction land and pace of expansion, establish compensation mechanism of land ecology. The research has great significance for China forming and further improving the policy system of land use of low-carbon emission.
