The purpose of this paper is to calculate the carbon emission of land use from 1997 to 2008 in Chongqing City, and analyze the characteristic of effect of land use on carbon emission, and divide the spatiotemporal difference types. The employed methods are documentation, inductive analysis and statistical analysis. The results indicate that:(1) carbon sink was greater than carbon source, the characteristic of carbon emission expressed as carbon absorption. the carbon absorption capacity took on the downward trend from 1997 to 2008, the total carbon uptake was -14 570.85 million tons in 2008 in Chongqing CIty, the government should control the rapid growth of carbon emission; (2) in the different types of land use, woodland is the main carbon sink and construction land is the main carbon source, the carbon emission of construction land grows fastest and increases by 9.89%; (3) the carbon emission per unit area of construction land and carbon emission per unit output value are higher, the emission intensity is found to be positively correlated with the level of economic development; (4) effects of land use on carbon emission are depended on many factors, energy consumption is the main source of carbon emission; (5) effects of land use on carbon emission of the forty counties are quite different, in order to achieve low-carbon-targert-oriented city, different strategies should be used for carbon emission reduction.
