Abstract: Based on the statistic area data of land utilization and energy consumption from 2001to 2010in Guizhou Province,we analyzed the effects of land uses on carbon emissions and their spatial-temporal patterns in Guizhou province by using carbon emission model.The conclusion could be drawn as follows:The total carbon emission was increasing with an annual rate of 2.9556×106t from 2001to 2010;The carbon emission by construction land had been contribution reaches above 96.86%,and there was an increasing trend;Carbon emission intensity decreased continuously,from 2.21×10-4 t·Yuan-1 in 2001falling to 1.21×10-4 t·Yuan-1 in 2010,with an annual decreased rate of 6.95%,lower than the increase rate of GDP which was 16.85%;Carbon emission payment imbalance,which caused ecological deficit;There were obvious differences in net carbon emission in 2010,with a gradually reducing trend from west to east.Liupanshui,southwest of Guizhou were the type of HE-LE(High emission-Low efficiency)while southeast of Guizhou,Tongren,Zunyi and Anshun were LE-HE(Low emissionHigh efficiency).Guiyang,south of Guizhou,Bijie were the type of ME-ME(Middle emission-Middle efficiency).
