Abstract

With the continuous economic and social development, the carbon emissions generated by the \Land is a human carrier of all social and economic activities, differentiated land use structure can effectively guide the macro industrial structure, technological level in the same kind of different industries, and its carbon emissions are very different. Based on the Yunnan Provincial Department of 1997-2008 land use change data and the \growth theory, industrial structure theory and the theory of low-carbon economy, based on the use of empirical analysis and normative analysis, comparative analysis and statistical analysis, qualitative and quantitative analysis method of combining the use of information entropy values ??of land use structure in Yunnan in 1997 to 2008 changes in land use structure description of the system. Analysis of this period of Land Use Structure Entropy reason for the change, as well as its carbon emissions and the province over the years changes in the relationship, and from the structure of land use restrictions based on low-carbon standards of construction land in Yunnan Province in 2020 predicted to be the number of in the context of a low-carbon economy in Yunnan Province of land use structure plan to provide a theoretical support and scientific references. Specific research process and the related conclusions are as follows: (a) from Yunnan Province from 1997 to 2008 information entropy values ??of land use structure change and Yunnan Province from 1997 to 2008 carbon emissions correlation was found between the two strong correlation. Unit root test method using both stationary test proved that both the stationary sequence, then use the var model to determine the optimal lag order of 2 after johansen cointegration test showed that there is between the two long-term stable relationship then use granger causality test to determine the structural changes in land use change is the cause of carbon emissions. In all types of land from 1997 to 2008 area changes with changes in carbon emissions by regression analysis found that farmland, orchard, woodland and grassland area change on carbon emissions impact of changes little, while urban and rural construction land and transportation, water conservation and other construction land change on the carbon emissions changes have a great impact. (2) were calculated Yunnan Province from 1997 to 2008 for key sites of carbon emissions, and then with the province from 1997 to 2008 a comparative analysis of carbon emissions. The results show that the construction site is the main source of carbon, and its carbon emissions over the years have accounted for the province's total carbon emissions of 93% or more, and construction land carbon emissions both in quantity and in the province's total carbon emissions are in a proportion has been rising, in 2008, the province's total to 96.45% of total carbon emissions. Woodlands are major carbon sinks, which over the years have accounted for the province's carbon sinks carbon sequestration by more than 99%; unit area of ??forest carbon sinks are carbon farmland and orchard row 242 times and 214 times that of construction land carbon emissions of 0.76 times. Finally, this paper based on our carbon targets limiting carbon emissions standards, the predicted scale of construction land in Yunnan Province in 2020 was 989 600 hm ~ 2. (3) For this analysis are presented in different aspects of the implementation of land use structure for the land, improve land use efficiency and reasonable intensive forest protection strategies such as low-carbon economy of the land use structure countermeasures.
