Spatial and temporal analysis of water pollution in China
- 74 Downloads
The relationship between water pollution and economic development, its regional differentiation and its temporal trend is analyzed. With the uneven distribution of water resources, the regional differentiation of water pollution in China is very obvious. Based on the index “RSR (the ratio of sewage to runoff)”, water pollution can be divided into five grades across the whole country. Overall, water pollution is more serious in north and northeast China. On the other hand, economic development level is not the only factor associated with water pollution. As for temporal change, with current economic growth and urbanization, it is impossible that water quality in China will be improved in the near future.
