| Abstract: | The remote sensing technique was used in combination with the geographic information system (GIS) technique in a study to monitor the spatial and temporal changes in soil erosion in Hechuan, Chongqing. The results showed that soil erosion in the region studied was being alleviated, both in area and in extent. Soil erosion showed several characteristics: great difference in space and time; erosion occurs synchronously with water and heat and the peak-hour of soil erosion arrives before the rush-hour of raining. |
