| Abstract: | Dynamical changes of soil erosion in Lizixi catchme nt of Sichuan province in 1986 and 1999 are monitored by remote sensing and geog raphical information system. Remote sensing images are basical information and s pace analysis of varieties of soil erosion are done by geographical information system software ARC/INFO. The quantity of soil erosion is estimated. These analy sis are done: dynamical changes of soil erosion, the relation between the change s of soil erosion and the changes of land use, the relation between the changes of the intensities of soil erosion and the quantity of soil erosion. This study provides the scientific basis and support of policy decision for soil and water conservation in Lizixi catchment. |
