Evolution Analysis Based on ESDA about the Spatial Pattern of COD, SO2 and TSP Emissions in China
Through the ESDA analysis,using the spatial analysis methods provided by Arcgis and GeoDA Software,this paper on Chinas COD,SO2 and TSP emission spatial pattern were analyzed.The results showed that:on the whole,China COD,SO2 and TSP emissions increased and then declined,that in recent years Chinese in the control of environmental pollution has made obvious achievement; pollutant emissions from East Central than the western,COD,and SO2 discharge of pollutants distribution pattern remained stable in 2004-2009,slightly fine-tuning; TSP emissions from the change of spatial pattern,significantly reduced the number of high-emission provinces of eastern and central regions,pollutant emissions growth index of the local autocorrelation,indicating that the emissions of environmental pollutants showed the characteristics of spatial concentration of high growth rate of the western region,the low growth rate of the eastern and central gathering.Finally,the analysis showed that Chinas emissions of the formation and development of the pattern of space influenced by the economic development level,resource endowment,technical level and the area industrial structure factors.
