Along with human economic and social development,Excessive carbon was emissioning to the air by our houman. The negative impact of the "greenhouse " is growing everyday.More and more scientists are focusing on how to save energy and reduce ,the emission of carbon to the air.The land is the vetor of all social and economic activities for human. the diverse of the land use structure can effectively made the macro-structure, and the emissions different . The Yunnan Province is in the upward phase of industrialization,and our province is one of the most important region in our china to reduce the carbon emissions.How to reduce reduce the carbon emissions is one of the major issue facing the development of our province.This article is based on the data of the land use change from 1997to 2008 of the yunnan province and the data of energe consumption data of yunnan province from 1997 to 2008.and use the theory of the sustainable use of land resources,the system theory,the smart growth theory,,The industrial structure theory and the theory of low-carbon economy,with the empirical analysis and normative analysis, the comparative analysis and the statistical analysis, the qualitative and quantitative analysis methods. This article use the information entropy value of the land use structure to describe land use change in Yunnan from 1997 to 2008. analyze the time structure of the information entropy of land use change because its carbon emissions and the province over the years the relationship between change and structural aspects of land use restrictions based on low-carbon standards in Yunnan Province in 2020 to forecast the number of construction sites in order to decrease the background for the low-carbon economy in Yunnan Province to provide a land use planning and scientific information supporting the theory. The follows are the conclusions:(1) with the analysis of the land use structure change of entropy of the Yunnan Province from 1997 to 2008 and the carbon emissions from 1997 to 2008 ,I found their was a strong correlation between them. And then I use the Unit root test method found that they are smooth. test both proved very stable between the two, in the use of var model to determine the optimal lag order of 2 after johansen cointegration test shows that their was a long-term stable relationship between them, I the use the granger causality test find that the structure of land use change is the reson of emission changes. Across the analysis of every changes type of land use changes and the carbon emissions over the years w showed that between them there are also a strong correlation.(2) calculated cultivated land, garden land and the construction of carbon emissions from 1997 to 2008 of the Yunnan Province and then use the data of carbon emissions from 1997 to 2008 to do a comparative analysis with them .The results showes that the forest is the major carbon sink unit area. The forest carbon sink volume is as most as 138 times of the carbon emission for the cultivated land and the garden land, or the 0.86 times same emissions land of construction. Cultivated land and orchard in the province's total carbon emissions account for a smaller proportion of carbon emissions, and reduce the area of its carbon emissions has decreased year by year. Construction land in terms of carbon emissions in the overall quantity and the proportion of total carbon emissions are in has been on the rise in 2008, its total carbon emissions accounted for the province's total 94.61 %. Based on this analysis, this paper, based on our 2020 carbon emissions target under the restrictions, predicted that the supply of land for construction Yunnan Province in 2020 is 1121400hm~2.(3) For the analyzes of the correlations of structure land use change and the carbon emissions .I find somde recomdations to reduce the the carbon emissions in the structure of land use .proposed for the differential for the land supplies ,Urge efficiency and rationality way to intensive the use of land .protected the forest as a major carbon sink for the realization of low-carbon economic strategy,.
