Abstract: Carbon emission and carbon absorption are the important factors affecting regional carbon cycle, and they are closely related to land use types. Carbon emissions and carbon absorptions are quite different from different land use types. In this paper, the carbon emissions and carbon absorptions of different land use types in Xinjiang during the period from 1995 to 2011 were estimated based on the statistical data and using the carbon emission and carbon absorption estimating formulas, and the relationship between carbon emission and economic development was analyzed. The results are as follows: ① In Xinjiang, the construction land use was the main source of carbon emission, but the forestland, cultivated land and grassland are the main land use types of carbon absorption; ② The total carbon emission of land use and the per capita carbon emission were rapidly increased year by year, but the total carbon absorption of land use was slowly increased year by year; ③ There was no an inversed “U-shaped” Kuznets curve of carbon emission environment of construction land, but an inversed “U-shaped” Kuznets curve of carbon emission environment of farmland use; ④ The land use carbon absorption was higher than its carbon emission, there was a carbon absorption surplus, but the surplus space was in a decrease trend.
