Abstract
It has become the international geosphere biosphere program, the world climate research programme and one of the core tasks of global change human factors plan that the global carbon cycle and curb greenhouse gas concentrations continue to rise , therefore, the existing biomass and carbon storage quantity of ecosystem research has important practical significance. We analyzed Jatropha curcas L biomass in Yunnan Simao district, basing on GPS location positioning, combining ARCGIS spatial analysis technology, selecting ecological factor such as altitude, slope, land use. Studies have shown that the Jatropha curcas L biomass under different land use types have significant differences by using the background data of these factors, with the help of space analysis method, combining with the measured data validation, respectively, it is: the most IS plantation, the second is cultivated land, the third is weeds, and the least is shrubbery. The research results can provide based data for Jatropha curcas L biomass and carbon storage calculation, also provide information for the decision-making department industry.
