- Abstract:
- Taking the Hongya County of Sichuan Province as a case, based on the technology of geographical information system and the model of soil erosion degree, the status of soil erosion was analyzed and evaluated. Results showed that:there were significant differences of the land use units in Hongya County and the intensity of soil erosion was close connection with the different land use types. According to the land use status and the natural and economic conditions, the status can be divided into three intensity zones of soil erosion, which are slight erosion of northern area, micro-degree erosion of central area and no significant erosion of southwest area;corresponding water conservation measures were made for various different situations which can provide scientific basis for soil and water conservation planning for the local government.
