The Temporal and Spatial Pattern of Wastewater Discharge in China

摘要

This paper mainly studies the 31 regions(not including Hong Kong,Macao and Taiwan) wastewater discharge temporal and spatial distribution through analysis of ten thousand Yuan GDP wastewater discharge.The results show that:the spatial distribution of wastewater discharge was concentrated,southern region higher than that in the north area,underdeveloped area is higher than that in developed regions.Generally speaking,the control effect of energy conservation is remarkable,with the development of economy;wastewater discharge of GDP per ten thousand has reduced obviously.But the effect is different from different regions,that underdeveloped areas are not very obvious; in the developed areas,along with the economic development and the upgrading of the industrial structure,the effect is remarkable.
