| Abstract: | Soil erosion has become a global environmental problems and a threat to human sustainable development.The status quo which researches spatial and temporal changes of soil erosion is concluded systematically.It is conducive to integrate and promote research methods of soil erosion and also conducive to the assessment and forecast of the status quo of soil erosion,and then proposes reasonable measures of management.This is an important technology means at present.This paper reviews systematically the general research methods,technical means and the developmental changes on spatial and temporal changes of soil erosion in China.It reviews research progress on spatial and temporal changes of soil erosion in China from the temporal scale and regional distribution and new research methods and technical means.It points the existing problems and future development trends and directions on spatial and temporal changes of soil erosion. |
| Keywords: | soil erosion time scale tegional distribution research methods "3S" technology |
