China's Provincial Carbon Emission System-Models And GIS

China is one of nations with major greenhouse gas emission. Facing the adverse effects of china caused by global climate warming, China has established a comprehensive policy measures to address climate warming. The formulation of provincial policies and measures need to be based on accurately estimating carbon emissions. In this paper, the study area was China's provinces and the spatial distribution of the carbon emission in provinces was the study content. Using software engineering theory we developed the geographic information system of China's provincial carbon emission. Then we analyzed the simulation results. There are six chapters in the thesis:The first chapter reviews the situation of research on the energy carbon emission, cement carbon emission and forest carbon sink, and then illustrate the necessity and the significance of study the special features of carbon emission and the establishment of the geographic information system.In the following, Chapterâ…¡shows the system functional requirements analysis, non-functional requirements analysis, data requirements analysis and hardware and software requirements analysis. On this basis of analysis system goals, system architecture and database subsystem are designed.The chapterâ…¢mainly focused on the establishment of carbon emission models. Model focused on three aspects:energy carbon emissions, cement carbon emissions, forest carbon sinks. CO2FIX models have been summarized in this chapter and this chapter shows the data sources and parameter selection.Chapterâ…£design and implement China's provincial carbon emission geographic information systems, with the development environment, VS.NET and ADO.NET data access technology and ArcGIS Engine component library.Next, chapter V analyze the spatial distribution pattern of energy carbon emissions, cement carbon emissions and forest carbon sinks. The conclusions are as follows: The trend of China's energy carbon emissions is largely the same as the one of energy consumption, which is dominant in the national carbon emissions. So we should adjust the existing energy structure and reduce the rate of fossil fuel carbon emissions, which is an effective means to reduce energy consumption.There is a faster increase in carbon emissions of cement industry, which requires China's cement industry increase the level of production technology and reduce energy consumption. At the same time, a planned manner should be implemented to prevent oversupply situation.China will take forest carbon sinks as an important measure for reducing China's carbon emissions, so we should be active in tree planting and other activities.Energy and cement carbon emissions of eastern coastal areas dominate in the country, but the forest carbon sink is in a small proportion of the whole country, so more effective carbon emission reduction measures should be to improve energy efficiency and production levels, to improve the energy structure in the eastern region.The central region has relatively less carbon emissions, but it has great potential for forest carbon sinks, so the central region should strengthen the maintenance of existing forests and the afforestation to improve the new area of forest playing important role as a carbon pool.Carbon emission and carbon sequestration potential are both relatively small in west region, but the west region has a rapid growth of carbon emissions. The west region should do economic development planning, implement effective carbon reduction policies to control the growth of carbon.In chapter VI we gave a brief summary of the full text, the shortcomings of the models and improvements in the future.
