Research On Land Use/land Cover Change And Carbon Storage In South East Asia During 2001-2010

Due to changes in the global environment is slowly threatening the sustainable development of human society, the change of land use has become one of the main contents of global change. In Southeast Asia, it is in the tropical area, a large area of forest, humid climate, land cover change faster are the reason why it selected as the study area, has certain representativeness. With the Land Cover data from MODIS MCD12Q1(IBGP classification scheme), the land use land cover change of the southeast Asia in the period from 2001 to 2010 is analyzed, to study the basic law of land use cover change from 2001 to 2010 in Southeast Asia, and analyze the transformation mode, and realize the sustainable utilization of land resources.Global warming affects the balance of ecosystem, and carbon cycle becomes a core problem in the study of global climate change. The terrestrial ecosystems is the main sources and sinks of global greenhouse gas, with biomass and soil organic matter carbon storage, the terrestrial ecosystem carbon out of the changes in the stock of global climate change has an important role. In Southeast Asia, due to the rapid development of the city, bringing many environmental problems, thus greatly affected the biodiversity and ecological balance. So it is important to study the change of carbon storage in Southeast Asia for the sustainable development in Southeast Asia region in 2001/2010. This paper mainly considers the carbon storage and sequestration of typical area in southeast Asia like Myanmar is calculated by the InVEST toolset, considering the four carbon pool including the aboveground biomass, belowground biomass, dead wood and soil carbon. And combined with the natural conditions, social and economic factors in Southeast Asia, the study of factors affecting the carbon reserves in Southeast Asia, to provide a basis for decision-making.The main conclusion lies in: 1) the land cove change of southeast Asia is obviously in the last decade driven by factors such as climate change, population growth, and economic development fast. Land cover change always take place between the dominated ecosystem—evergreen broadleaved forest and other land cover type, paddy, rain feed crop enhanced remarkable, bare ground present increasing trend also. 2) the human activities affect the ecosystem services via the land use land cover change. The carbon storage and sequestration is stabilized in the Myanmar as a whole in the period, while some human dominated area decrease. The carbon storage and sequestration in human dominated ecosystem is decreased for both the area enlarge via land conversion and harvest rate enhance of built-up and city, agricultural area, which are also harmful to the ecosystem resilience. In ten years, woodland, grassland and savanna grassland carbon storage decreased and farmland mosaic carbon reserves increased significantly. The effect of temperature on carbon sink is negatively correlated and the impact of rainfall on the carbon sink is positively correlated. Both population and GDP have a positive correlation to the carbon sink. In the future, to harmonize the human-environment relationship and push the regional sustainable development, the land use spatial regulation, land use density reduction are should be viewed.
